-.TH SCAPY 1 "May 12, 2003"
-.SH NAME
-scapy \- Interactive packet manipulation tool
-.SH SYNOPSIS
-.B scapy
-.RI [ options ]
-.SH DESCRIPTION
-This manual page documents briefly the
-.B scapy
-tool.
-.PP
-\fBscapy\fP is a powerful interactive packet manipulation tool, 
-packet generator, network scanner, network discovery, packet sniffer,
-etc. It can for the moment replace hping, parts of nmap, arpspoof, arp-sk,
-arping, tcpdump, tshark, p0f, ...
-.PP
-\fBscapy\fP uses the python interpreter as a command board. That means that 
-you can use directly python language (assign variables, use loops, 
-define functions, etc.) If you give a file as parameter when you run 
-\fBscapy\fP, your session (variables, functions, intances, ...) will be saved 
-when you leave the interpretor, and restored the next time you launch
-\fBscapy\fP. 
-.PP
-The idea is simple. Those kind of tools do two things : sending packets 
-and receiving answers. That's what \fBscapy\fP does : you define a set of 
-packets, it sends them, receives answers, matches requests with answers 
-and returns a list of packet couples (request, answer) and a list of 
-unmatched packets. This has the big advantage over tools like nmap or 
-hping that an answer is not reduced to (open/closed/filtered), but is 
-the whole packet. 
-.PP
-On top of this can be build more high level functions, for example one 
-that does traceroutes and give as a result only the start TTL of the 
-request and the source IP of the answer. One that pings a whole network 
-and gives the list of machines answering. One that does a portscan and 
-returns a LaTeX report. 
-
-.SH OPTIONS
-Options for scapy are:
-.TP
-\fB\-h\fR
-display usage
-.TP
-\fB\-d\fR
-increase log verbosity. Can be used many times.
-.TP
-\fB\-s\fR FILE
-use FILE to save/load session values (variables, functions, intances, ...) 
-.TP
-\fB\-p\fR PRESTART_FILE 
-use PRESTART_FILE instead of $HOME/.scapy_prestart.py as pre-startup file
-.TP
-\fB\-P\fR
-do not run prestart file
-.TP
-\fB\-c\fR STARTUP_FILE 
-use STARTUP_FILE instead of $HOME/.scapy_startup.py as startup file
-.TP
-\fB\-C\fR
-do not run startup file
-
-.SH COMMANDS
-Only the vital commands to begin are listed here for the moment.
-.TP
-\fBls()\fR
-lists supported protocol layers. If a protocol layer is given as parameter, lists its fields and types of fields.
-.TP
-\fBlsc()\fR
-lists some user commands. If a command is given as parameter, its documentation is displayed.
-.TP
-\fBconf\fR
-this object contains the configuration. 
-
-.SH FILES
-\fB$HOME/.scapy_prestart.py\fR
-This file is run before scapy core is loaded. Only the \fb\conf\fP object 
-is available. This file can be used to manipulate \fBconf.load_layers\fP 
-list to choose which layers will be loaded:
-
-.nf
-conf.load_layers.remove("bluetooth")
-conf.load_layers.append("new_layer")
-.fi
-
-\fB$HOME/.scapy_startup.py\fR
-This file is run after scapy is loaded. It can be used to configure
-some of the scapy behaviors:
-
-.nf
-conf.prog.pdfreader="xpdf"
-split_layers(UDP,DNS)
-.fi
-
-.SH EXAMPLES
-
-More verbose examples are available at
-http://www.secdev.org/projects/scapy/demo.html
-Just run \fBscapy\fP and try the following commands in the interpreter.
-
-.LP
-Test the robustness of a network stack with invalid packets:
-.nf
-sr(IP(dst="172.16.1.1", ihl=2, options="\verb$\x02$", version=3)/ICMP())
-.fi
-
-.LP
-Packet sniffing and dissection (with a bpf filter or thetereal-like output):
-.nf
-a=sniff(filter="tcp port 110")
-a=sniff(prn = lambda x: x.display) 
-.fi
-
-.LP
-Sniffed packet reemission:
-.nf
-a=sniff(filter="tcp port 110")
-sendp(a)
-.fi
-
-.LP
-Pcap file packet reemission:
-.nf
-sendp(rdpcap("file.cap"))
-.fi
-
-.LP
-Manual TCP traceroute:
-.nf
-sr(IP(dst="www.google.com", ttl=(1,30))/TCP(seq=RandInt(), sport=RandShort(), dport=dport)
-.fi
-
-.LP
-Protocol scan:
-.nf
-sr(IP(dst="172.16.1.28", proto=(1,254)))
-.fi
-
-.LP
-ARP ping:
-.nf
-srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst="172.16.1.1/24"))
-.fi
-
-.LP
-ACK scan:
-.nf
-sr(IP(dst="172.16.1.28")/TCP(dport=(1,1024), flags="A"))
-.fi
-
-.LP
-Passive OS fingerprinting:
-.nf
-sniff(prn=prnp0f) 
-.fi
-
-.LP
-Active OS fingerprinting:
-.nf
-nmap_fp("172.16.1.232")
-.fi
-
-
-.LP
-ARP cache poisonning:
-.nf
-sendp(Ether(dst=tmac)/ARP(op="who-has", psrc=victim, pdst=target))
-.fi
-
-.LP
-Reporting:
-.nf
-report_ports("192.168.2.34", (20,30))
-.fi
-
-.SH SEE ALSO
-
-.nf
-http://www.secdev.org/projects/scapy
-http://trac.secdev.org/scapy
-.fi
-
-.SH BUGS
-Does not give the right source IP for routes that use interface aliases.
-
-May miss packets under heavy load.
-
-Session saving is limited by Python ability to marshal objects. As a 
-consequence, lambda functions and generators can't be saved, which seriously
-reduce usefulness of this feature. 
-
-BPF filters don't work on Point-to-point interfaces.

+# How to contribute
+
+Contributors are essential to Scapy (as they are to most open source
+projects). Here is some advice to help you help the project!
+
+## Project objectives
+
+We try to keep Scapy as powerful as possible, to support as many
+protocols and platforms as possible, to keep and make the code (and
+the commit history) as clean as possible.
+
+Since Scapy can be slow and memory consuming, we try to limit CPU and
+memory usage, particularly in parts of the code often called.
+
+## What to contribute
+
+You want to spend time working on Scapy but have no (or little)
+idea what to do? You can look for open issues
+[labeled "contributions wanted"](https://github.com/secdev/scapy/labels/contributions%20wanted), or look at the [contributions roadmap](https://github.com/secdev/scapy/issues/399)
+
+If you have any ideas of useful contributions that you cannot (or do
+not want to) do yourself, open an issue and use the label
+"contributions wanted".
+
+Once you have chosen a contribution, open an issue to let other people
+know you're working on it (or assign the existing issue to yourself)
+and track your progress. You might want to ask whether you're working
+in an appropriate direction, to avoid the frustration of seeing your
+contribution rejected after a lot of work.
+
+## Reporting issues
+
+### Questions
+
+It is OK so submit issues to ask questions (more than OK,
+encouraged). There is a label "question" that you can use for that.
+
+### Bugs
+
+If you have installed Scapy through a package manager (from your Linux
+or BSD system, from PyPI, etc.), please get and install the current
+development code, and check that the bug still exists before
+submitting an issue.
+
+Please label your issues "bug".
+
+If you're not sure whether a behavior is a bug or not, submit an issue
+and ask, don't be shy!
+
+### Enhancements / feature requests
+
+If you want a feature in Scapy, but cannot implement it yourself or
+want some hints on how to do that, open an issue with label
+"enhancement".
+
+Explain if possible the API you would like to have (e.g., give examples
+of function calls, packet creations, etc.).
+
+## Submitting pull requests
+
+### Coding style & conventions
+
+First, Scapy "legacy" code contains a lot of code that do not comply
+with the following recommendations, but we try to comply with some
+guidelines for new code.
+
+-   The code should be PEP-8 compliant; you can check your code with
+    [pep8](https://pypi.python.org/pypi/pep8).
+
+-   [Pylint](http://www.pylint.org/) can help you write good Python
+    code (even if respecting Pylint rules is sometimes either too hard
+    or even undesirable; human brain needed!).
+
+-   [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html)
+    is a nice read!
+
+-   Avoid creating unnecessary `list` objects, particularly if they
+    can be huge (e.g., when possible, use `scapy.modules.six.range()` instead of
+    `range()`, `for line in fdesc` instead of `for line in
+    fdesc.readlines()`; more generally prefer generators over lists).
+
+### Tests
+
+Please consider adding tests for your new features or that trigger the
+bug you are fixing. This will prevent a regression from being
+unnoticed. Do not use the variable `_`  in your tests, as it could break them.
+
+If you find yourself in a situation where your tests locally succeed  but 
+fail if executed on the CI, try to enable the debugging option for the 
+dissector by setting `conf.debug_dissector = 1`.
+
+### New protocols
+
+New protocols can go either in `scapy/layers` or to
+`scapy/contrib`. Protocols in `scapy/layers` should be usually found
+on common networks, while protocols in `scapy/contrib` should be
+uncommon or specific.
+
+To be precise, `scapy/layers` protocols should not be importing `scapy/contrib`
+protocols, whereas `scapy/contrib` protocols may import both `scapy/contrib` and
+`scapy/layers` protocols.
+
+The detailed requirements are explained in [Design patterns](https://scapy.readthedocs.io/en/latest/build_dissect.html#design-patterns) on Scapy's doc.
+
+### Features
+
+Protocol-related features should be implemented within the same module
+as the protocol layers(s) (e.g., `traceroute()` is implemented in
+`scapy/layers/inet.py`).
+
+Other features may be implemented in a module (`scapy/modules`) or a
+contribution (`scapy/contrib`).
+
+### Core
+
+If you contribute to Scapy's core (e.g., `scapy/base_classes.py`,
+`scapy/packet.py`, etc.), please be very careful with performances and
+memory footprint, as it is easy to write Python code that wastes
+memory or CPU cycles.
+
+As an example, `Packet().__init__()` is called each time a **layer** is
+parsed from a string (during a network capture or a PCAP file
+read). Adding inefficient code here will have a disastrous effect on
+Scapy's performances.
+
+### Python 2 and 3 compatibility
+
+The project aims to provide code that works both on Python 2 and Python 3. Therefore, some rules need to be applied to achieve compatibility:
+
+-   byte-string must be defined as `b"\x00\x01\x02"`
+-   exceptions must comply with the new Python 3 format: `except SomeError as e:`
+-   lambdas must be written using a single argument when using tuples: use `lambda x, y: x + f(y)` instead of `lambda (x, y): x + f(y)`.
+-   use int instead of long
+-   use list comprehension instead of map() and filter()
+-   use scapy.modules.six.moves.range instead of xrange and range
+-   use scapy.modules.six.itervalues(dict) instead of dict.values() or dict.itervalues()
+-   use scapy.modules.six.string_types instead of basestring
+-   `__bool__ = __nonzero__` must be used when declaring `__nonzero__` methods
+-   `__next__ = next` must be used when declaring `next` methods in iterators
+-   `StopIteration` must NOT be used in generators (but it can still be used in iterators)
+-   `io.BytesIO` must be used instead of `StringIO` when using bytes
+-   `__cmp__` must not be used.
+-   UserDict should be imported via `six.UserDict`
+
+### Code review
+
+Maintainers tend to be picky, and you might feel frustrated that your
+code (which is perfectly working in your use case) is not merged
+faster.
+
+Please don't be offended, and keep in mind that maintainers are
+concerned about code maintainability and readability, commit history
+(we use the history a lot, for example to find regressions or
+understand why certain decisions have been made), performances,
+integration in Scapy, API consistency (so that someone who knows how
+to use Scapy will know how to use your code), etc.
+
+**Thanks for reading, happy hacking!**

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+
+Scapy is a powerful Python-based interactive packet manipulation program and
+library.
+
+It is able to forge or decode packets of a wide number of protocols, send them
+on the wire, capture them, store or read them using pcap files, match requests
+and replies, and much more. It is designed to allow fast packet prototyping by
+using default values that work.
+
+It can easily handle most classical tasks like scanning, tracerouting, probing,
+unit tests, attacks or network discovery (it can replace `hping`, 85% of `nmap`,
+`arpspoof`, `arp-sk`, `arping`, `tcpdump`, `wireshark`, `p0f`, etc.). It also
+performs very well at a lot of other specific tasks that most other tools can't
+handle, like sending invalid frames, injecting your own 802.11 frames, combining
+techniques (VLAN hopping+ARP cache poisoning, VoIP decoding on WEP protected
+channel, ...), etc.
+
+Scapy supports Python 2.7 and Python 3 (3.4 to 3.7). It's intended to
+be cross platform, and runs on many different platforms (Linux, OSX,
+\*BSD, and Windows).
+
+## Getting started
+
+Scapy is usable either as a **shell** or as a **library**.
+For further details, please head over to [Getting started with Scapy](https://scapy.readthedocs.io/en/latest/introduction.html), which is part of the documentation.
+
+### Shell demo
+
+![Scapy install demo](https://secdev.github.io/img/animation-scapy-install.svg)
+
+Scapy can easily be used as an interactive shell to interact with the network.
+The following example shows how to send an ICMP Echo Request message to
+`github.com`, then display the reply source IP address:
+
+```python
+sudo ./run_scapy
+Welcome to Scapy
+>>> p = IP(dst="github.com")/ICMP()
+>>> r = sr1(p)
+Begin emission:
+.Finished to send 1 packets.

+## [Installation](https://scapy.readthedocs.io/en/latest/installation.html)
+
+Scapy works without any external Python modules on Linux and BSD like operating
+systems. On Windows, you need to install some mandatory dependencies as
+described in [the
+documentation](http://scapy.readthedocs.io/en/latest/installation.html#windows).
+
+On most systems, using Scapy is as simple as running the following commands:
+
+```bash
+git clone https://github.com/secdev/scapy
+cd scapy
+./run_scapy
+```
+
+To benefit from all Scapy features, such as plotting, you might want to install
+Python modules, such as `matplotlib` or `cryptography`. See the
+[documentation](http://scapy.readthedocs.io/en/latest/installation.html) and
+follow the instructions to install them.

+.TH SCAPY 1 "May 8, 2018"
+.SH NAME
+scapy \- Interactive packet manipulation tool
+.SH SYNOPSIS
+.B scapy
+.RI [ options ]
+.SH DESCRIPTION
+This manual page documents briefly the
+.B Scapy
+tool.
+.PP
+\fBScapy\fP is a powerful interactive packet manipulation tool, 
+packet generator, network scanner, network discovery, packet sniffer,
+etc. It can for the moment replace hping, parts of nmap, arpspoof, arp-sk,
+arping, tcpdump, tshark, p0f, ...
+.PP
+\fBScapy\fP uses the Python interpreter as a command board. That means that 
+you can use directly Python language (assign variables, use loops, 
+define functions, etc.) If you give a file a parameter when you run 
+\fBScapy\fP, your session (variables, functions, instances, ...) will be saved 
+when you leave the interpreter and restored the next time you launch
+\fBScapy\fP. 
+.PP
+The idea is simple. Those kinds of tools do two things : sending packets 
+and receiving answers. That's what \fBScapy\fP does : you define a set of 
+packets, it sends them, receives answers, matches requests with answers 
+and returns a list of packet couples (request, answer) and a list of 
+unmatched packets. This has the big advantage over tools like nmap or 
+hping that an answer is not reduced to (open/closed/filtered), but is 
+the whole packet. 
+.PP
+On top of this can be used to build more high-level functions, for example, one 
+that does traceroutes and give as a result only the start TTL of the 
+request and the source IP of the answer. One that pings a whole network 
+and gives the list of machines answering. One that does a portscan and 
+returns a LaTeX report. 
+
+.SH OPTIONS
+Options for Scapy are:
+.TP
+\fB\-h\fR
+display usage
+.TP
+\fB\-d\fR
+increase log verbosity. Can be used many times.
+.TP
+\fB\-s\fR FILE
+use FILE to save/load session values (variables, functions, instances, ...) 
+.TP
+\fB\-p\fR PRESTART_FILE 
+use PRESTART_FILE instead of $HOME/.scapy_prestart.py as pre-startup file
+.TP
+\fB\-P\fR
+do not run prestart file
+.TP
+\fB\-c\fR STARTUP_FILE 
+use STARTUP_FILE instead of $HOME/.scapy_startup.py as startup file
+.TP
+\fB\-C\fR
+do not run startup file
+
+.SH COMMANDS
+Only the vital commands to begin are listed here for the moment.
+.TP
+\fBls()\fR
+lists supported protocol layers.
+If a protocol layer is given as parameter, lists its fields and types of fields.
+If a string is given as parameter, it is used to filter the layers.
+.TP
+\fBexplore()\fR
+explores available protocols.
+Allows to look for a layer or protocol through an interactive GUI.
+If a Scapy module is given as parameter, explore this specific module.
+.TP
+\fBlsc()\fR
+lists scapy's main user commands.
+.TP
+\fBconf\fR
+this object contains the configuration. 
+
+.SH FILES
+\fB$HOME/.scapy_prestart.py\fR
+This file is run before Scapy core is loaded. Only the \fBconf\fP object
+is available. This file can be used to manipulate \fBconf.load_layers\fP 
+list to choose which layers will be loaded:
+
+.nf
+conf.load_layers.remove("bluetooth")
+conf.load_layers.append("new_layer")
+.fi
+
+\fB$HOME/.scapy_startup.py\fR
+This file is run after Scapy is loaded. It can be used to configure
+some of the Scapy behaviors:
+
+.nf
+conf.prog.pdfreader = "xpdf"
+split_layers(UDP,DNS)
+.fi
+
+.SH EXAMPLES
+
+More verbose examples are available in the documentation
+https://scapy.readthedocs.io/
+Just run \fBscapy\fP and try the following commands in the interpreter.
+
+.LP
+Test the robustness of a network stack with invalid packets:
+.nf
+sr(IP(dst="172.16.1.1", ihl=2, options=["verb$2"], version=3)/ICMP(), timeout=2)
+.fi
+
+.LP
+Packet sniffing and dissection (with a bpf filter or tshark-like output):
+.nf
+a=sniff(filter="tcp port 110")
+a=sniff(prn = lambda x: x.display) 
+.fi
+
+.LP
+Sniffed packet re-emission:
+.nf
+a=sniff(filter="tcp port 110")
+sendp(a)
+.fi
+
+.LP
+Pcap file packet re-emission:
+.nf
+sendp(rdpcap("file.cap"))
+.fi
+
+.LP
+Manual TCP traceroute:
+.nf
+sr(IP(dst="www.google.com", ttl=(1,30))/TCP(seq=RandInt(), sport=RandShort(), dport=dport)
+.fi
+
+.LP
+Protocol scan:
+.nf
+sr(IP(dst="172.16.1.28", proto=(1,254)))
+.fi
+
+.LP
+ARP ping:
+.nf
+srp(Ether(dst="ff:ff:ff:ff:ff:ff")/ARP(pdst="172.16.1.1/24"))
+.fi
+
+.LP
+ACK scan:
+.nf
+sr(IP(dst="172.16.1.28")/TCP(dport=(1,1024), flags="A"))
+.fi
+
+.LP
+Passive OS fingerprinting:
+.nf
+sniff(prn=prnp0f) 
+.fi
+
+.LP
+Active OS fingerprinting:
+.nf
+nmap_fp("172.16.1.232")
+.fi
+
+
+.LP
+ARP cache poisoning:
+.nf
+sendp(Ether(dst=tmac)/ARP(op="who-has", psrc=victim, pdst=target))
+.fi
+
+.LP
+Reporting:
+.nf
+report_ports("192.168.2.34", (20,30))

+.fi
+
+.SH BUGS
+Does not give the right source IP for routes that use interface aliases.
+
+May miss packets under heavy load. This is a restriction from python itself
+
+Session saving is limited by Python ability to marshal objects. As a 
+consequence, lambda functions and generators can't be saved, which seriously
+reduce the usefulness of this feature. 
+
+BPF filters don't work on Point-to-point interfaces.

-ASN.1 provides basic objects: integers, many kinds of strings, floats, booleans, containers, etc. They are grouped in the so called Universal class. A given protocol can provide other objects which will be grouped in the Context class. For example, SNMP defines PDU_GET or PDU_SET objects. There are also the Application and Private classes.

-Each of theses objects is given a tag that will be used by the encoding rules. Tags from 1 are used for Universal class. 1 is boolean, 2 is integer, 3 is a bit string, 6 is an OID, 48 is for a sequence. Tags from the ``Context`` class begin at 0xa0. When encountering an object tagged by 0xa0, we'll need to know the context to be able to decode it. For example, in SNMP context, 0xa0 is a PDU_GET object, while in X509 context, it is a container for the certificate version.

For example, in SNMP context, 0xa0 is a PDU_GET object, while in X509 context, it is a container for the certificate version.
 
 Other objects are created by assembling all those basic brick objects. The composition is done using sequences and arrays (sets) of previously defined or existing objects. The final object (an X509 certificate, a SNMP packet) is a tree whose non-leaf nodes are sequences and sets objects (or derived context objects), and whose leaf nodes are integers, strings, OID, etc.
 
 Scapy and ASN.1
 ---------------
 
-Scapy provides a way to easily encode or decode ASN.1 and also program those encoders/decoders. It is quite more lax than what an ASN.1 parser should be, and it kind of ignores constraints. It won't replace neither an ASN.1 parser nor an ASN.1 compiler. Actually, it has been written to be able to encode and decode broken ASN.1. It can handle corrupted encoded strings and can also create those.

 Automata
 ========
 
-Scapy enables to create easily network automata. Scapy does not stick to a specific model like Moore or Mealy automata. It provides a flexible way for you to choose you way to go.
+Scapy enables to create easily network automata. Scapy does not stick to a specific model like Moore or Mealy automata. It provides a flexible way for you to choose your way to go.
 
-An automaton in Scapy is deterministic. It has different states. A start state and some end and error states. There are transitions from one state to another. Transitions can be transitions on a specific condition, transitions on the reception of a specific packet or transitions on a timeout. When a transition is taken, one or more actions can be run. An action can be bound to many transitions. Parameters can be passed from states to transitions and from transitions to states and actions.
+An automaton in Scapy is deterministic. It has different states. A start state and some end and error states. There are transitions from one state to another. Transitions can be transitions on a specific condition, transitions on the reception of a specific packet or transitions on a timeout. When a transition is taken, one or more actions can be run. An action can be bound to many transitions. Parameters can be passed from states to transitions, and from transitions to states and actions.
 
 From a programmer's point of view, states, transitions and actions are methods from an Automaton subclass. They are decorated to provide meta-information needed in order for the automaton to work.

+PipeTools
+=========
+
+Pipetool is a smart piping system allowing to perform complex stream data management. There are various differences between PipeTools and Automatons:
+
+- PipeTools have no states: data is always sent following the same pattern
+- PipeTools are not based on sockets but can handle more varied sources of data (and outputs) such as user input, pcap input (but also sniffing)
+- PipeTools are not class-based, but rather implemented by manually linking all their parts. That has drawbacks but allows to dynamically add a Source, Drain while running, and set multiple drains for the same source
+
+.. note:: Pipetool default objects are located inside ``scapy.pipetool``
+
+Class Types
+-----------
+
+There are 3 different class of objects used for data management:
+
+- ``Sources``
+- ``Drains``
+- ``Sinks``
+
+They are executed and handled by a ``PipeEngine`` object.
+
+When running, a pipetool engine waits for any available data from the Source, and send it in the Drains linked to it.
+The data then goes from Drains to Drains until it arrives in a Sink, the final state of this data.
+
+Here is a basic demo of what the PipeTool system can do
+
+.. image:: graphics/pipetool_engine.png
+
+For instance, this engine was generated with this code:
+
+>>> s = CLIFeeder()
+>>> s2 = CLIHighFeeder()
+>>> d1 = Drain()
+>>> d2 = TransformDrain(lambda x: x[::-1])
+>>> si1 = ConsoleSink()
+>>> si2 = QueueSink()
+>>> 
+>>> s > d1
+>>> d1 > si1
+>>> d1 > si2
+>>> 
+>>> s2 >> d1
+>>> d1 >> d2
+>>> d2 >> si1
+>>> 
+>>> p = PipeEngine()
+>>> p.add(s)
+>>> p.add(s2)
+>>> p.graph(target="> the_above_image.png")
+
+Let's start our PipeEngine:
+
+>>> p.start()
+
+Now, let's play with it:
+
+>>> s.send("foo")
+>'foo'
+>>> s2.send("bar")
+>>'rab'
+>>> s.send("i like potato")
+>'i like potato'
+>>> print(si2.recv(), ":", si2.recv())
+foo : i like potato
+
+Let's study what happens here:
+
+- there are two canals in a PipeEngine, a lower one and a higher one. Some Sources write on the lower one, some on the higher one and some on both.
+- most sources can be linked to any drain, on both lower and higher canals. The use of `>` indicates a link on the low canal, and `>>` on the higher one.
+- when we send some data in `s`, which is on the lower canal, as shown above, it goes through the `Drain` then is sent to the `QueueSink` and to the `ConsoleSink`
+- when we send some data in `s2`, it goes through the Drain, then the TransformDrain where the data is reversed (see the lambda), before being sent to `ConsoleSink` only. This explains why we only have the data of the lower sources inside the QueueSink: the higher one has not been linked.
+
+Most of the sinks receive from both lower and upper canals. This is verifiable using the `help(ConsoleSink)`
+
+>>> help(ConsoleSink)

+
+
+Sources
+^^^^^^^
+
+A Source is a class that generates some data.
+
+There are several source types integrated with Scapy, usable as-is, but you may
+also create yours.
+
+Default Source classes
+~~~~~~~~~~~~~~~~~~~~~~
+
+For any of those class, have a look at ``help([theclass])`` to get more information or the required parameters.
+
+- CLIFeeder : a source especially used in interactive software. its ``send(data)`` generates the event data on the lower canal
+- CLIHighFeeder : same than CLIFeeder, but writes on the higher canal
+- PeriodicSource : Generate messages periodically on the low canal.
+- AutoSource: the default source, that must be extended to create custom sources. 
+
+Create a custom Source
+~~~~~~~~~~~~~~~~~~~~~~
+
+To create a custom source, one must extend the ``AutoSource`` class.
+
+Do NOT use the default ``Source`` class except if you are really sure of what you are doing: it is only used internally, and is missing some implementation. The ``AutoSource`` is made to be used.
+
+
+To send data through it, the object must call its ``self._gen_data(msg)`` or ``self._gen_high_data(msg)`` functions, which send the data into the PipeEngine.
+
+The Source should also (if possible), set ``self.is_exhausted`` to ``True`` when empty, to allow the clean stop of the ``PipeEngine``. If the source is infinite, it will need a force-stop (see PipeEngine below)
+
+For instance, here is how CLIHighFeeder is implemented::
+
+    class CLIFeeder(CLIFeeder):
+        def send(self, msg):
+            self._gen_high_data(msg)
+        def close(self):
+            self.is_exhausted = True
+
+Drains
+^^^^^^
+
+Default Drain classes
+~~~~~~~~~~~~~~~~~~~~~
+
+Drains need to be linked on the entry that you are using. It can be either on the lower one (using ``>``) or the upper one (using ``>>``).
+See the basic example above.
+
+- Drain : the most basic Drain possible. Will pass on both low and high entry if linked properly.
+- TransformDrain : Apply a function to messages on low and high entry
+- UpDrain : Repeat messages from low entry to high exit
+- DownDrain : Repeat messages from high entry to low exit
+
+Create a custom Drain
+~~~~~~~~~~~~~~~~~~~~~
+
+To create a custom drain, one must extend the ``Drain`` class.
+
+A ``Drain`` object will receive data from the lower canal in its ``push`` method, and from the higher canal from its ``high_push`` method.
+
+To send the data back into the next linked Drain / Sink, it must call the ``self._send(msg)`` or ``self._high_send(msg)`` methods.
+
+For instance, here is how TransformDrain is implemented::
+
+    class TransformDrain(Drain):
+        def __init__(self, f, name=None):
+            Drain.__init__(self, name=name)
+            self.f = f
+        def push(self, msg):
+            self._send(self.f(msg))
+        def high_push(self, msg):
+            self._high_send(self.f(msg))
+
+Sinks
+^^^^^
+
+Sinks are destinations for messages.
+
+A :py:class:`Sink` receives data like a :py:class:`Drain`, but doesn't send any
+messages after it.
+
+Messages on the low entry come from :py:meth:`~Sink.push`, and messages on the
+high entry come from :py:meth:`~Sink.high_push`.
+
+Default Sink classes
+~~~~~~~~~~~~~~~~~~~~
+
+.. py:class:: Sink
+
+    Does nothing; interface to extend for custom sinks.
+
+    All sinks have the following constructor parameters:
+
+    :param name: a human-readable name for the element
+    :type name: str
+
+    All sinks should implement at least one of these methods:
+
+    .. py:method:: push
+
+        Called by :py:class:`PipeEngine` when there is a new message for the
+        low entry.
+
+        :param msg: The message data
+        :returns: None
+        :rtype: None
+
+    .. py:method:: high_push
+
+        Called by :py:class:`PipeEngine` when there is a new message for the
+        high entry.
+
+        :param msg: The message data
+        :returns: None
+        :rtype: None
+
+.. py:class:: ConsoleSink
+
+    Prints messages on the low and high entries to ``stdout``.
+
+.. py:class:: RawConsoleSink
+
+    Prints messages on the low and high entries, using :py:func:`os.write`.
+
+    :param newlines: Include a new-line character after printing each packet.
+                     Defaults to True.
+    :type newlines: bool
+
+.. py:class:: TermSink
+
+    Prints messages on the low and high entries, on a separate terminal (xterm
+    or cmd).
+
+    :param keepterm: Leaves the terminal window open after :py:meth:`~Pipe.stop`
+                     is called. Defaults to True.
+    :type keepterm: bool
+    :param newlines: Include a new-line character after printing each packet.
+                     Defaults to True.
+    :type newlines: bool
+    :param openearly: Automatically starts the terminal when the constructor is
+                      called, rather than waiting for :py:meth:`~Pipe.start`.
+                      Defaults to True.
+    :type openearly: bool
+
+.. py:class:: QueueSink
+
+    Collects messages on the low and high entries into a :py:class:`Queue`.
+
+    Messages are dequeued with :py:meth:`recv`.
+
+    Both high and low entries share the same :py:class:`Queue`.
+
+    .. py:method:: recv
+
+        Reads the next message from the queue.
+
+        If no message is available in the queue, returns None.
+
+        :param block: Blocks execution until a packet is available in the queue.
+                      Defaults to True.
+        :type block: bool
+        :param timeout: Controls how long to wait if ``block=True``. If None
+                        (the default), this method will wait forever. If a
+                        non-negative number, this is a number of seconds to
+                        wait before giving up (and returning None).
+        :type timeout: None, int or float
+
+.. py:class:: WiresharkSink
+
+    Streams :py:class:`Packet` from the low entry to Wireshark.
+
+    Packets are written into a ``pcap`` stream (like :py:class:`WrpcapSink`),
+    and streamed to a new Wireshark process on its ``stdin``.
+
+    Wireshark is run with the ``-ki -`` arguments, which cause it to treat
+    ``stdin`` as a capture device.  Arguments in :py:attr:`args` will be
+    appended after this.
+
+    Extends :py:mod:`WrpcapSink`.
+
+    :param linktype: See :py:attr:`WrpcapSink.linktype`.
+    :type linktype: None or int
+    :param args: See :py:attr:`args`.
+    :type args: None or list[str]
+
+    .. py:attribute:: args
+
+        Additional arguments for the Wireshark process.
+
+        This must be either ``None`` (the default), or a ``list`` of ``str``.
+
+        This attribute has no effect after calling :py:meth:`PipeEngine.start`.
+
+        See :manpage:`wireshark(1)` for more details.
+
+.. py:class:: WrpcapSink
+
+    Writes :py:class:`Packet` on the low entry to a ``pcap`` file.
+
+    Ignores all messages on the high entry.
+
+    .. note::
+
+        Due to limitations of the ``pcap`` format, all packets **must** be of
+        the same link type. This class will not mutate packets to conform with
+        the expected link type.
+
+    :param fname: Filename to write packets to.
+    :type fname: str
+    :param linktype: See :py:attr:`linktype`.
+    :type linktype: None or int
+
+    .. py:attribute:: linktype
+
+        Set an explicit link-type (``DLT_``) for packets.  This must be an
+        ``int`` or ``None``.
+
+        This is the same as the :py:func:`wrpcap` ``linktype`` parameter.
+
+        If ``None`` (the default), the linktype will be auto-detected on the
+        first packet. This field will *not* be updated with the result of this
+        auto-detection.
+
+        This attribute has no effect after calling :py:meth:`PipeEngine.start`.
+
+
+Create a custom Sink
+~~~~~~~~~~~~~~~~~~~~
+
+To create a custom sink, one must extend :py:class:`Sink` and implement
+:py:meth:`~Sink.push` and/or :py:meth:`~Sink.high_push`.
+
+This is a simplified version of :py:class:`ConsoleSink`:
+
+.. code-block:: python3
+
+    class ConsoleSink(Sink):
+        def push(self, msg):
+            print(">%r" % msg)
+        def high_push(self, msg):
+            print(">>%r" % msg)
+
+Link objects
+------------
+
+As shown in the example, most sources can be linked to any drain, on both low
+and high entry.
+
+The use of ``>`` indicates a link on the low entry, and ``>>`` on the high
+entry.
+
+For example, to link ``a``, ``b`` and ``c`` on the low entries:
+
+.. code-block:: pycon
+
+    >>> a = CLIFeeder()
+    >>> b = Drain()
+    >>> c = ConsoleSink()
+    >>> a > b > c
+    >>> p = PipeEngine()
+    >>> p.add(a)
+
+This wouldn't link the high entries, so something like this would do nothing:
+
+.. code-block:: pycon
+
+    >>> a2 = CLIHighFeeder()
+    >>> a2 >> b
+    >>> a2.send("hello")
+
+Because ``b`` (:py:class:`Drain`) and ``c`` (:py:class:`ConsoleSink`) are not
+linked on the high entry.
+
+However, using a :py:class:`DownDrain` would bring the high messages from
+:py:class:`CLIHighFeeder` to the lower channel:
+
+.. code-block:: pycon
+
+    >>> a2 = CLIHighFeeder()
+    >>> b2 = DownDrain()
+    >>> a2 >> b2
+    >>> b2 > b
+    >>> a2.send("hello")
+
+The PipeEngine class
+--------------------
+
+The ``PipeEngine`` class is the core class of the Pipetool system. It must be initialized and passed the list of all Sources.
+
+There are two ways of passing sources:
+
+- during initialization: ``p = PipeEngine(source1, source2, ...)``
+- using the ``add(source)`` method
+
+A ``PipeEngine`` class must be started with ``.start()`` function. It may be force-stopped with the ``.stop()``, or cleanly stopped with ``.wait_and_stop()``
+
+A clean stop only works if the Sources is exhausted (has no data to send left).
+
+It can be printed into a graph using ``.graph()`` methods. see ``help(do_graph)`` for the list of available keyword arguments.
+
+Scapy advanced PipeTool objects
+-------------------------------
+
+.. note:: Unlike the previous objects, those are not located in ``scapy.pipetool`` but in ``scapy.scapypipes``
+
+Now that you know the default PipeTool objects, here are some more advanced ones, based on packet functionalities.
+
+- SniffSource : Read packets from an interface and send them to low exit.
+- RdpcapSource : Read packets from a PCAP file send them to low exit.
+- InjectSink : Packets received on low input are injected (sent) to an interface
+- WrpcapSink : Packets received on low input are written to PCAP file
+- UDPDrain : UDP payloads received on high entry are sent over UDP (complicated, have a look at ``help(UDPDrain)``)
+- FDSourceSink : Use a file descriptor as source and sink
+- TCPConnectPipe : TCP connect to addr:port and use it as source and sink
+- TCPListenPipe : TCP listen on [addr:]port and use the first connection as source and sink (complicated, have a look at ``help(TCPListenPipe)``)
+
+Triggering
+----------
+
+Some special sort of Drains exists: the Trigger Drains.
+
+Trigger Drains are special drains, that on receiving data not only pass it by but also send a "Trigger" input, that is received and handled by the next triggered drain (if it exists).
+
+For example, here is a basic TriggerDrain usage:
+
+>>> a = CLIFeeder()
+>>> d = TriggerDrain(lambda msg: True) # Pass messages and trigger when a condition is met
+>>> d2 = TriggeredValve()
+>>> s = ConsoleSink()
+>>> a > d > d2 > s
+>>> d ^ d2 # Link the triggers
+>>> p = PipeEngine(s)
+>>> p.start()
+INFO: Pipe engine thread started.
+>>> 
+>>> a.send("this will be printed")
+>'this will be printed'
+>>> a.send("this won't, because the valve was switched")
+>>> a.send("this will, because the valve was switched again")
+>'this will, because the valve was switched again'
+>>> p.stop()
+
+Several triggering Drains exist, they are pretty explicit. It is highly recommended to check the doc using ``help([the class])``
+
+- TriggeredMessage : Send a preloaded message when triggered and trigger in chain
+- TriggerDrain : Pass messages and trigger when a condition is met
+- TriggeredValve : Let messages alternatively pass or not, changing on trigger
+- TriggeredQueueingValve : Let messages alternatively pass or queued, changing on trigger
+- TriggeredSwitch : Let messages alternatively high or low, changing on trigger

 This is about how fields that have a variable length can be handled with Scapy. These fields usually know their length from another field. Let's call them varfield and lenfield. The idea is to make each field reference the other so that when a packet is dissected, varfield can know its length from lenfield when a packet is assembled, you don't have to fill lenfield, that will deduce its value directly from varfield value.
 
-Problems arise whe you realize that the relation between lenfield and varfield is not always straightforward. Sometimes, lenfield indicates a length in bytes, sometimes a number of objects. Sometimes the length includes the header part, so that you must substract the fixed header length to deduce the varfield length. Sometimes the length is not counted in bytes but in 16bits words. Sometimes the same lenfield is used by two different varfields. Sometimes the same varfield is referenced by two lenfields, one in bytes one in 16bits words.

 The length field
 ~~~~~~~~~~~~~~~~
 
-First, a lenfield is declared using ``FieldLenField`` (or a derivate). If its value is None when assembling a packet, its value will be deduced from the varfield that was referenced. The reference is done using either the ``length_of`` parameter or the ``count_of`` parameter. The ``count_of`` parameter has a meaning only when varfield is a field that holds a list (``PacketListField`` or ``FieldListField``). The value will be the name of the varfield, as a string. According to which parameter is used the ``i2len()`` or ``i2count()`` method will be called on the varfield value. The returned value will the be adjusted by the function provided in the adjust parameter. adjust will be applied on 2 arguments: the packet instance and the value returned by ``i2len()`` or ``i2count()``.

+Design patterns
+===============
+Some patterns are similar to a lot of protocols and thus can be described the same way in Scapy.
+
+The following parts will present several models and conventions that can be followed when implementing a new protocol.
+
+Field naming convention
+-----------------------
+The goal is to keep the writing of packets fluent and intuitive. The basic instructions are the following :
+
+* Use inverted camel case and common abbreviations (e.g. len, src, dst, dstPort, srcIp).
+* Wherever it is either possible or relevant, prefer using the names from the specifications. This aims to help newcomers to easily forge packets.
+
+Add new protocols to Scapy
+--------------------------
+
+New protocols can go either in ``scapy/layers`` or to ``scapy/contrib``. Protocols in ``scapy/layers`` should be usually found on common networks, while protocols in ``scapy/contrib`` should be uncommon or specific.
+
+To be precise, ``scapy/layers`` protocols should not be importing ``scapy/contrib`` protocols, whereas ``scapy/contrib`` protocols may import both ``scapy/contrib`` and ``scapy/layers`` protocols.
+
+Scapy provides an ``explore()`` function, to search through the available layer/contrib modules. Therefore, modules contributed back to Scapy must provide information about them, knowingly:
+
+- A **contrib** module must have defined, near the top of the module (below the license header is a good place) **(without the brackets)** `Example <https://github.com/secdev/scapy/blob/0f6ac82ed66919a20226a3d8d164b810c8eb293c/scapy/contrib/openflow.py#L11-L12>`_ ::
+
+    # scapy.contrib.description = [...]
+    # scapy.contrib.status = [...]
+    # scapy.contrib.name = [...] (optional)
+
+- If the contrib module does not contain any packets, and should not be indexed in `explore()`, then you should instead set::
+
+    # scapy.contrib.status = skip 
+
+- A **layer** module must have a docstring, in which the first line shortly describes the module.

+Improve the documentation
+=========================
+
+The documentation can be improved in several ways by:
+
+* Adding docstrings to the source code.
+* Adding usage examples to the documentation.
+
+Adding Docstrings
+-----------------
+The Scapy source code has few explanations of what a function is doing. A docstring, by adding explanation and
+expected input and output parameters, helps saving time for both the layer developers and the users looking for
+advanced features.
+
+An example of docstring from the ``scapy.fields.FlagsField`` class: ::
+
+  class FlagsField(BitField):
+    """ Handle Flag type field
 
+     Make sure all your flags have a label
+
+     Example:
+         >>> from scapy.packet import Packet
+         >>> class FlagsTest(Packet):
+                 fields_desc = [FlagsField("flags", 0, 8, ["f0", "f1", "f2", "f3", "f4", "f5", "f6", "f7"])]
+         >>> FlagsTest(flags=9).show2()
+         ###[ FlagsTest ]###
+           flags     = f0+f3
+         >>> FlagsTest(flags=0).show2().strip()
+         ###[ FlagsTest ]###
+           flags     =
+
+     :param name: field's name
+     :param default: default value for the field
+     :param size: number of bits in the field
+     :param names: (list or dict) label for each flag, Least Significant Bit tag's name is written first
+     """
+
+It will contain a short one-line description of the class followed by some indications about its usage.
+You can add a usage example if it makes sense using the `doctest <https://docs.python.org/2.7/library/doctest.html>`_ format.
+Finally, the classic python signature can be added following the `sphinx documentation  <http://www.sphinx-doc.org/en/stable/domains.html#python-signatures>`_.
+
+This task works in pair with writing non regression unit tests.
+
+Documentation
+-------------
+A way to improve the documentation content is by keeping it up to date with the latest version of Scapy. You can also help by adding usage examples of your own or directly gathered from existing online Scapy presentations.
 
 Testing with UTScapy

 UTScapy is a small Python program that reads a campaign of tests, runs the campaign with Scapy and generates a report indicating test status. The report may be in one of four formats, text, ansi, HTML or LaTeX.
 
-Three basic test containers exist with UTScapy, a unit test, a test set and a test campaign. A unit test is a list of Scapy commands that will be run by Scapy or a derived work of Scapy. Evaluation of the last command in the unit test will determine the end result of the individual unit test. A test set is a group of unit tests with some association. A test campaign consists of one or more test sets. Test sets and unit tests can be given keywords to form logical groupings. When running a campaign, tests may be selected by keyword. This allows the user to run tests within a desired grouping.

 For each unit test, test set and campaign, a CRC32 of the test is calculated and displayed as a signature of that test. This test signature is sufficient to determine that the actual test run was the one expected and not one that has been modified. In case your dealing with evil people that try to modify or corrupt the file without changing the CRC32, a global SHA1 is computed on the whole file.

 It is important to note that UTScapy uses the truth value from the last Python statement as the indicator as to whether a test passed or failed. Multiple logical tests may appear on the last line. If the result is 0 or False, the test fails. Otherwise, the test passes. Use of an assert() statement can force evaluation of intermediate values if needed.

+
+Using tox to test Scapy
+-----------------------
+
+The ``tox`` command simplifies testing Scapy. It will automatically create
+virtual environments and install the mandatory Python modules.
+
+For example, on a fresh Debian installation, the following command will start
+all Scapy unit tests automatically without any external dependency::
+
+ tox -- -K vcan_socket -K tcpdump -K tshark -K nmap -K manufdb -K crypto
+
+VIM syntax highlighting for .uts files
+--------------------------------------
+
+Copy all files from ``scapy/doc/syntax/vim_uts_syntax/ftdetect`` and ``scapy/doc/syntax/vim_uts_syntax/syntax`` into ``~/.vim/`` and preserve the folder structure.
+
+If ftdetect/filetype.vim already exists, you might need to modify this file manually.
+
+These commands will do the installation::
+
+ cp -i -v ftdetect/filetype.vim $HOME/.vim/ftdetect/filetype.vim
+ cp -i -v ftdetect/uts.vim $HOME/.vim/ftdetect/uts.vim
+ cp -i -v syntax/uts.vim $HOME/.vim/syntax/uts.vim
+
+Alternatively, a install script in ``scapy/doc/syntax/vim_uts_syntax/`` does the installation automatically.
+
+
+Releasing Scapy
+---------------
+
+Under the hood, a Scapy release is represented as a signed git tag. Prior to
+signing a commit, the maintainer that wishes to create a release must:
+
+* check that the corresponding Travis and AppVeyor tests pass
+* run ``./run_scapy`` locally
+* run ``tox``
+* run unit tests on BSD using the Vagrant setup from ``scapy/doc/vagrant_ci/``
+
+Taking v2.4.3 as an example, the following commands can be used to sign and
+publish the release::
+
+ git tag -s v2.4.3 -m "Release 2.4.3"
+ git tag v2.4.3 -v
+ git push --tags
+
+Release Candidates (RC) could also be done. For example, the first RC will be
+tagged v2.4.3rc1 and the message ``2.4.3 Release Candidate #1``.
+
+Prior to uploading the release to PyPi, the ``author_email`` in ``setup.py``
+must be changed to the address of the maintainer performing the release. The
+following commands can then be used::
+
+ python3 setup.py sdist
+ twine check dist/scapy-2.4.3.tar.gz
+ twine upload dist/scapy-2.4.3.tar.gz

-At the moment, there are two different versions of Scapy:
+Scapy versions
+==============
 
-* **Scapy v1.x**. It consists of only one file and works on Python 2.4, so it might be easier to install.
-  Moreover, your OS may already have a specially prepared packages or ports for it. Last version is v1.2.2.
-* **Scapy v2.x**. The current development version adds several features (e.g. IPv6). It consists of several
-  files  packaged in the standard distutils way. Scapy v2 needs Python 2.5.

-Download the `latest version <http://scapy.net>`_ to a temporary directory and install it in the standard `distutils <http://docs.python.org/inst/inst.html>`_ way::
-
-$ cd /tmp
-$ wget scapy.net 
-$ unzip scapy-latest.zip
-$ cd scapy-2.*
-$ sudo python setup.py install
- 
-Alternatively, you can execute the zip file::
-
-$ chmod +x scapy-latest.zip
-$ sudo ./scapy-latest.zip
-
-or::
-
-$ sudo sh scapy-latest.zip
+.. note::
+   To get the latest versions, with bugfixes and new features, but maybe not as stable, see the `development version <#current-development-version>`_.

-.. note::
+In fact, since 2.4.3, Scapy comes in 3 bundles:
 
-   To make a zip executable, some bytes have been added before the zip header.
-   Most zip programs handle this, but not all. If your zip program complains

+If you always want the latest version with all new features and bugfixes, use Scapy's Git repository:
 
-1. Install the `Mercurial <http://www.selenic.com/mercurial/>`_ version control system. For example, on Debian/Ubuntu use::
-
-      $ sudo apt-get install mercurial
-
-   or on OpenBSD:: 
-    
-      $ pkg_add mercurial
+1. `Install the Git version control system <https://git-scm.com/book/en/v2/Getting-Started-Installing-Git>`_.
 
 2. Check out a clone of Scapy's repository::
-    
-   $ hg clone http://hg.secdev.org/scapy
-    
-3. Install Scapy in the standard distutils way:: 
-    
-   $ cd scapy
-   $ sudo python setup.py install
-    
-Then you can always update to the latest version::
 
-$ hg pull
-$ hg update       
-$ sudo python setup.py install
- 
-For more information about Mercurial, have a look at the `Mercurial book <http://hgbook.red-bean.com/>`_. 
+   $ git clone https://github.com/secdev/scapy.git
+
+.. note::
+	You can also download Scapy's `latest version <https://github.com/secdev/scapy/archive/master.zip>`_ in a zip file::
 
+	$ wget --trust-server-names https://github.com/secdev/scapy/archive/master.zip   # or wget -O master.zip https://github.com/secdev/scapy/archive/master.zip
+	$ unzip master.zip
+	$ cd master
 
-Installing Scapy v1.2
-=====================
+3. Install Scapy in the standard `distutils <https://docs.python.org/3/distutils/setupscript.html>`_ way:: 
 
-As Scapy v1 consists only of one single Python file, installation is easy:
-Just download the last version and run it with your Python interpreter::
+   $ cd scapy
+   $ sudo python setup.py install
 
- $ wget http://hg.secdev.org/scapy/raw-file/v1.2.0.2/scapy.py
- $ sudo python scapy.py
+If you used Git, you can always update to the latest version afterwards::
 
-.. index::
-   single: scapy-bpf
+   $ git pull
+   $ sudo python setup.py install
 
-On BSD systems, you can also try the latest version of `Scapy-bpf <http://hg.natisbad.org/scapy-bpf/raw-file/tip/scapy.py>`_ (`development repository <http://hg.natisbad.org/scapy-bpf/>`_). It doesn't need libpcap or libdnet.
+.. note::
 
+   You can run scapy without installing it using the ``run_scapy`` (unix) or ``run_scapy.bat`` (Windows) script or running it directly from the executable zip file (see the previous section).
 
-Optional software for special features
-======================================
+Optional Dependencies
+=====================
 
-For some special features you have to install more software. 
-Platform-specific instructions on how to install those packages can be found in the next chapter.
+For some special features, Scapy will need some dependencies to be installed.
+Most of those software are installable via ``pip``.
 Here are the topics involved and some examples that you can use to try if your installation was successful.
 
 .. index::
    single: plot()
 
-* Plotting. ``plot()`` needs `Gnuplot-py <http://gnuplot-py.sourceforge.net/>`_ which needs `GnuPlot <http://www.gnuplot.info/>`_ and `NumPy <http://numpy.scipy.org/>`_.
+* Plotting. ``plot()`` needs `Matplotlib <https://matplotlib.org/>`_.
+
+  Matplotlib is installable via ``pip install matplotlib``
  
   .. code-block:: python

-     >>> p.plot(lambda x:len(x))
+    >>> p=sniff(count=50)
+    >>> p.plot(lambda x:len(x))
  
-* 2D graphics. ``psdump()`` and ``pdfdump()`` need `PyX <http://pyx.sourceforge.net/>`_ which in turn needs a `LaTeX distribution <http://www.tug.org/texlive/>`_. For viewing the PDF and PS files interactively, you also need `Adobe Reader <http://www.adobe.com/products/reader/>`_ (``acroread``) and `gv <http://wwwthep.physik.uni-mainz.de/~plass/gv/>`_ (``gv``). 
+* 2D graphics. ``psdump()`` and ``pdfdump()`` need `PyX <http://pyx.sourceforge.net/>`_ which in turn needs a LaTeX distribution: `texlive (Unix) <http://www.tug.org/texlive/>`_ or `MikTex (Windows) <https://miktex.org/>`_.
+  
+  Note: PyX requires version <=0.12.1 on Python 2.7. This means that on Python 2.7, it needs to be installed via ``pip install pyx==0.12.1``. Otherwise ``pip install pyx``

 Platform-specific instructions
 ==============================
 
+As a general rule, you can toggle the **libpcap** integration `on` or `off` at any time, using::
+
+    from scapy.config import conf
+    conf.use_pcap = True
+
 Linux native
 ------------
 
-Scapy can run natively on Linux, without libdnet and libpcap.
+Scapy can run natively on Linux, without libpcap.
 
-* Install `Python 2.5 <http://www.python.org>`_.
+* Install `Python 2.7 or 3.4+ <http://www.python.org>`_.
 * Install `tcpdump <http://www.tcpdump.org>`_ and make sure it is in the $PATH. (It's only used to compile BPF filters (``-ddd option``))
 * Make sure your kernel has Packet sockets selected (``CONFIG_PACKET``)
 * If your kernel is < 2.6, make sure that Socket filtering is selected ``CONFIG_FILTER``) 
 
-Debian/Ubuntu
--------------
+Debian/Ubuntu/Fedora
+--------------------
 
-Just use the standard packages::
+Make sure tcpdump is installed:
 
-$ sudo apt-get install tcpdump graphviz imagemagick python-gnuplot python-crypto python-pyx 
-

-    # cd gnuplot-py-1.8
-    # python setup.py install
+	$ yum install tcpdump
+
+Then install Scapy via ``pip`` or ``apt`` (bundled under ``python-scapy``)
+All dependencies may be installed either via the platform-specific installer, or via PyPI. See `Optional Dependencies <#optional-dependencies>`_ for more information.
 
 
 Mac OS X
 --------
 
-Here's how to install Scapy on Mac OS 10.4 (Tiger) or 10.5 (Leopard).
-
-Set up a development environment
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-1. Install X11. 
-   On the Mac OS X DVD, it is located in the "Optional Installs.mpkg" package.
- 
-2. Install SDK.
-   On the Mac OS X DVD, it is located in the "Xcode Tools/Packages" directory.
+On Mac OS X, Scapy **DOES work natively** since the recent versions.
+However, you may want to make Scapy use libpcap.
+You can choose to install it using either Homebrew or MacPorts. They both
+work fine, yet Homebrew is used to run unit tests with
+`Travis CI <https://travis-ci.org>`_. 
 
-3. Install Python 2.5 from Python.org.
-   Using Apple's Python version will lead to some problems.
-   Get it from http://www.python.org/ftp/python/2.5.2/python-2.5.2-macosx.dmg
+.. note:: 
+    Libpcap might already be installed on your platform (for instance, if you have tcpdump). This is the case of `OSX <https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/pcap.3.html>`_
 
-Install using MacPorts
+Install using Homebrew
 ^^^^^^^^^^^^^^^^^^^^^^
 
-3. Install MacPorts
-   Download the dmg from macports.org and install it.
-     
-4. Update MacPorts::
+1. Update Homebrew::
 
-   $ sudo port -d selfupdate
+   $ brew update
 
-5. Install Scapy::
+2. Install libpcap::
 
-   $ sudo port install scapy
+   $ brew install libpcap
 
-You can then update to the latest version as shown in the generic installation above. 
+Enable it In Scapy::
 
-Install from original sources
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+    conf.use_pcap = True
 
-Install libdnet and its Python wrapper::
+Install using MacPorts
+^^^^^^^^^^^^^^^^^^^^^^
+
+1. Update MacPorts::
 
- $ wget http://libdnet.googlecode.com/files/libdnet-1.12.tgz
- $ tar xfz libdnet-1.12.tgz 
- $ ./configure
- $ make
- $ sudo make install
- $ cd python
- $ python2.5 setup.py install
+   $ sudo port -d selfupdate
 
-Install libpcap and its Python wrapper::
+2. Install libpcap::
 
- $ wget http://dfn.dl.sourceforge.net/sourceforge/pylibpcap/pylibpcap-0.6.2.tar.gz
- $ tar xfz pylibpcap-0.6.2.tar.gz
- $ cd pylibpcap-0.6.2
- $ python2.5 setup.py install
+   $ sudo port install libpcap
 
-Optionally: Install readline::
+Enable it In Scapy::
 
- $ python `python -c "import pimp; print pimp.__file__"` -i readline
+    conf.use_pcap = True
 
 OpenBSD
 -------
 
-Here's how to install Scapy on OpenBSD 4.3.
+In a similar manner, to install Scapy on OpenBSD 5.9+, you **may** want to install libpcap, if you do not want to use the native extension:
 
 .. code-block:: text
 
- # export PKG_PATH=ftp://ftp.openbsd.org/pub/OpenBSD/4.3/packages/i386/
- # pkg_add py-libpcap py-libdnet mercurial
- # ln -sf /usr/local/bin/python2.5 /usr/local/bin/python
- # cd /tmp
- # hg clone http://hg.secdev.org/scapy
- # cd scapy
- # python setup.py install
+	$ doas pkg_add libpcap tcpdump
 
+Then install Scapy via ``pip`` or ``pkg_add`` (bundled under ``python-scapy``)
+All dependencies may be installed either via the platform-specific installer, or via PyPI. See `Optional Dependencies <#optional-dependencies>`_ for more information.
 
-Optional packages
-^^^^^^^^^^^^^^^^^
-
-py-crypto
-
-.. code-block:: text
+SunOS / Solaris
+---------------
 
- # pkg_add py-crypto
+Solaris / SunOS requires ``libpcap`` (installed by default) to work.
 
-gnuplot and its Python binding: 
-
-.. code-block:: text
-
- # pkg_add gnuplot py-gnuplot
-
-Graphviz (large download, will install several GNOME libraries)
-
-.. code-block:: text
-
- # pkg_add graphviz
-
-   
-ImageMagick (takes long to compile)
-
-.. code-block:: text
-
- # cd /tmp
- # ftp ftp://ftp.openbsd.org/pub/OpenBSD/4.3/ports.tar.gz 
- # cd /usr
- # tar xvfz /tmp/ports.tar.gz 
- # cd /usr/ports/graphics/ImageMagick/
- # make install
-
-PyX (very large download, will install texlive etc.)
-
-.. code-block:: text
-
- # pkg_add py-pyx
+.. note::
+    In fact, Solaris doesn't support `AF_PACKET`, which Scapy uses on Linux, but rather uses its own system `DLPI`. See `this page <https://www.oracle.com/technetwork/server-storage/solaris/solaris-linux-app-139382.html>`_.
+    We prefer using the very universal `libpcap` that spending time implementing support for `DLPI`.

-python-bz2 (for UTscapy)
+Scapy is primarily being developed for Unix-like systems and works best on those platforms. But the latest version of Scapy supports Windows out-of-the-box. So you can use nearly all of Scapy's features on your Windows machine as well.
 
-.. code-block:: text
+.. image:: graphics/scapy-win-screenshot1.png
+   :scale: 80
+   :align: center
 
- # pkg_add python-bz2    
+You need the following software in order to install Scapy on Windows:
 
-.. _windows_installation:
+  * `Python <http://www.python.org>`_: `Python 2.7.X or 3.4+ <https://www.python.org/downloads/>`_. After installation, add the Python installation directory and its \Scripts subdirectory to your PATH. Depending on your Python version, the defaults would be ``C:\Python27`` and ``C:\Python27\Scripts`` respectively.
+  * `Npcap <https://nmap.org/npcap/>`_: `the latest version <https://nmap.org/npcap/#download>`_. Default values are recommended. Scapy will also work with Winpcap.
+  * `Scapy <http://www.secdev.org/projects/scapy/>`_: `latest development version <https://github.com/secdev/scapy/archive/master.zip>`_ from the `Git repository <https://github.com/secdev/scapy>`_. Unzip the archive, open a command prompt in that directory and run ``python setup.py install``. 
 
-Windows
--------
+Just download the files and run the setup program. Choosing the default installation options should be safe. (In the case of ``Npcap``, Scapy **will work** with ``802.11`` option enabled. You might want to make sure that this is ticked when installing).
 
-.. sectionauthor:: Dirk Loss <mail at dirk-loss.de>
+After all packages are installed, open a command prompt (cmd.exe) and run Scapy by typing ``scapy``. If you have set the PATH correctly, this will find a little batch file in your ``C:\Python27\Scripts`` directory and instruct the Python interpreter to load Scapy.
 
-Scapy is primarily being developed for Unix-like systems and works best on those platforms. But the latest version of Scapy supports Windows out-of-the-box. So you can use nearly all of Scapy's features on your Windows machine as well.
+If really nothing seems to work, consider skipping the Windows version and using Scapy from a Linux Live CD -- either in a virtual machine on your Windows host or by booting from CDROM: An older version of Scapy is already included in grml and BackTrack for example. While using the Live CD you can easily upgrade to the latest Scapy version by using the `above installation methods <#installing-scapy-v2-x>`_.
 
-.. note::
-   If you update from Scapy-win v1.2.0.2 to Scapy v2 remember to use ``from scapy.all import *`` instead of ``from scapy import *``.

+Known bugs
+^^^^^^^^^^
 
-  * `Python <http://www.python.org>`_: `python-2.5.4.msi <http://www.python.org/ftp/python/2.5.4/python-2.5.4.msi>`_. `python-2.6.3.msi <http://www.python.org/ftp/python/2.6.3/python-2.6.3.msi>`_. After installation, add the Python installation directory and its \Scripts subdirectory to your PATH. Depending on your Python version, the defaults would be ``C:\Python25`` and ``C:\Python25\Scripts`` or ``C:\Python26`` and ``C:\Python26\Scripts`` respectively.
-  * `Scapy <http://www.secdev.org/projects/scapy/>`_: `latest development version <http://hg.secdev.org/scapy/archive/tip.zip>`_ from the `Mercurial repository <http://hg.secdev.org/scapy>`_. Unzip the archive, open a command prompt in that directory and run "python setup.py install". 
-  * `pywin32 <http://python.net/crew/mhammond/win32/Downloads.html>`_: `pywin32-214.win32-py2.5.exe <http://surfnet.dl.sourceforge.net/sourceforge/pywin32/pywin32-214.win32-py2.5.exe>`_ `pywin32-214.win32-py2.6.exe <http://downloads.sourceforge.net/project/pywin32/pywin32/Build%20214/pywin32-214.win32-py2.6.exe>`_
-  * `WinPcap <http://www.winpcap.org/>`_: `WinPcap_4_1_1.exe <http://www.winpcap.org/install/bin/WinPcap_4_1_1.exe>`_. You might want to choose "[x] Automatically start the WinPcap driver at boot time", so that non-privileged users can sniff, especially under Vista and Windows 7. If you want to use the ethernet vendor database to resolve MAC addresses or use the ``wireshark()`` command, download `Wireshark <http://www.wireshark.org/>`_ which already includes WinPcap. 
-  * `pypcap <http://code.google.com/p/pypcap/>`_: `pcap-1.1-scapy-20090720.win32-py25.exe <http://www.secdev.org/projects/scapy/files/pcap-1.1-scapy-20090720.win32-py2.5.exe>`_ `pcap-1.1-scapy-20090720.win32-py2.6.exe <http://www.secdev.org/projects/scapy/files/pcap-1.1-scapy-20090720.win32-py2.6.exe>`_. This is a *special version for Scapy*, as the original leads to some timing problems. Now works on Vista and Windows 7, too. Under Vista/Win7 please right-click on the installer and choose "Run as administrator".
-  * `libdnet <http://code.google.com/p/libdnet/>`_:  `dnet-1.12.win32-py2.5.exe <http://libdnet.googlecode.com/files/dnet-1.12.win32-py2.5.exe>`_ `dnet-1.12.win32-py2.6.exe <http://www.secdev.org/projects/scapy/files/dnet-1.12.win32-py2.6.exe>`_. Under Vista/Win7 please right-click on the installer and choose "Run as administrator"
-  * `pyreadline <http://ipython.scipy.org/moin/PyReadline/Intro>`_: `pyreadline-1.5-win32-setup.exe <http://ipython.scipy.org/dist/pyreadline-1.5-win32-setup.exe>`_
+You may bump into the following bugs, which are platform-specific, if Scapy didn't manage work around them automatically:
 
-Just download the files and run the setup program. Choosing the default installation options should be safe.
+ * You may not be able to capture WLAN traffic on Windows. Reasons are explained on the `Wireshark wiki <https://wiki.wireshark.org/CaptureSetup/WLAN>`_ and in the `WinPcap FAQ <https://www.winpcap.org/misc/faq.htm>`_. Try switching off promiscuous mode with ``conf.sniff_promisc=False``.
+ * Packets sometimes cannot be sent to localhost (or local IP addresses on your own host).
+ 
+Winpcap/Npcap conflicts
+^^^^^^^^^^^^^^^^^^^^^^^
 
-For your convenience direct links are given to the versions I used (for Python 2.5 and Python 2.6). If these links do not work or if you are using a different Python version, just visit the homepage of the respective package and look for a Windows binary. As a last resort, search the web for the filename.
+As ``Winpcap`` is becoming old, it's recommended to use ``Npcap`` instead. ``Npcap`` is part of the ``Nmap`` project.
 
-After all packages are installed, open a command prompt (cmd.exe) and run Scapy by typing ``scapy``. If you have set the PATH correctly, this will find a little batch file in your ``C:\Python26\Scripts`` directory and instruct the Python interpreter to load Scapy.
+.. note::
+    This does NOT apply for Windows XP, which isn't supported by ``Npcap``.
 
-If really nothing seems to work, consider skipping the Windows version and using Scapy from a Linux Live CD -- either in a virtual machine on your Windows host or by booting from CDROM: An older version of Scapy is already included in grml and BackTrack for example. While using the Live CD you can easily upgrade to the lastest Scapy version by typing ``cd /tmp && wget scapy.net``.
+1. If you get the message ``'Winpcap is installed over Npcap.'`` it means that you have installed both Winpcap and Npcap versions, which isn't recommended.
 
-Optional packages
-^^^^^^^^^^^^^^^^^
+You may first **uninstall winpcap from your Program Files**, then you will need to remove::
 
-Plotting (``plot``)
+    C:/Windows/System32/wpcap.dll
+    C:/Windows/System32/Packet.dll
 
- * `GnuPlot <http://www.gnuplot.info/>`_: `gp420win32.zip <http://downloads.sourceforge.net/gnuplot/gp420win32.zip>`_. Extract the zip file (e.g. to ``c:\gnuplot``) and add the ``gnuplot\bin`` directory to your PATH.

 The idea is simple. Scapy mainly does two things: sending packets and receiving answers. You define a set of packets, it sends them, receives answers, matches requests with answers and returns a list of packet couples (request, answer) and a list of unmatched packets. This has the big advantage over tools like Nmap or hping that an answer is not reduced to (open/closed/filtered), but is the whole packet.
 
-On top of this can be build more high level functions, for example one that does traceroutes and give as a result only the start TTL of the request and the source IP of the answer. One that pings a whole network and gives the list of machines answering. One that does a portscan and returns a LaTeX report.

 What makes Scapy so special
 ===========================
 
-First, with most other networking tools, you won't build someting the author did not imagine. These tools have been built for a specific goal and can't deviate much from it. For example, an ARP cache poisoning program won't let you use double 802.1q encapsulation. Or try to find a program that can send, say, an ICMP packet with padding (I said *padding*, not *payload*, see?). In fact, each time you have a new need, you have to build a new tool.

Or try to find a program that can send, say, an ICMP packet with padding (I said *padding*, not *payload*, see?). In fact, each time you have a new need, you have to build a new tool.
 
-Second, they usually confuse decoding and interpreting. Machines are good at decoding and can help human beings with that. Interpretation is reserved to human beings. Some programs try to mimic this behaviour. For instance they say "*this port is open*" instead of "*I received a SYN-ACK*". Sometimes they are right. Sometimes not. It's easier for beginners, but when you know what you're doing, you keep on trying to deduce what really happened from the program's interpretation to make your own, which is hard because you lost a big amount of information. And you often end up using ``tcpdump -xX`` to decode and interpret what the tool missed.

 Third, even programs which only decode do not give you all the information they received. The network's vision they give you is the one their author thought was sufficient. But it is not complete, and you have a bias. For instance, do you know a tool that reports the Ethernet padding?
 
-Scapy tries to overcome those problems. It enables you to build exactly the packets you want. Even if I think stacking a 802.1q layer on top of TCP has no sense, it may have some for somebody else working on some product I don't know. Scapy has a flexible model that tries to avoid such arbitrary limits. You're free to put any value you want in any field you want, and stack them like you want. You're an adult after all.

+Automotive Penetration Testing with Scapy
+*****************************************
+
+.. note::
+    All automotive related features work best on Linux systems. CANSockets and ISOTPSockets in Scapy are based on Linux kernel modules.
+    The python-can project is used to support CAN and CANSockets on other systems, besides Linux.
+    This guide explains the hardware setup on a BeagleBone Black. The BeagleBone Black was chosen because of its two CAN interfaces on the main processor.
+    The presence of two CAN interfaces in one device gives the possibility of CAN MITM attacks and session hijacking.
+    The Cannelloni framework turns a BeagleBone Black into a CAN-to-UDP interface, which gives you the freedom to run Scapy
+    on a more powerful machine.
+
+Protocols

+The following table should give a brief overview about all automotive capabilities
+of Scapy. Most application layer protocols have many specialized ``Packet`` classes.

+The class ``ISOTPSocket`` can be set to a ``ISOTPNativeSocket`` or a ``ISOTPSoftSocket``.
+The decision is made dependent on the configuration ``conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': True}`` (to select ``ISOTPNativeSocket``) or
+``conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': False}`` (to select ``ISOTPSoftSocket``).
+This will allow you to write platform independent code. Apply this configuration before loading the ISOTP layer
+with ``load_contrib("isotp")``.
+
+Another remark in respect to ISOTPSocket compatibility. Always use with for socket creation. Example::
+
+    with ISOTPSocket("vcan0", did=0x241, sid=0x641) as sock:

+
+   bashCommand = "/bin/bash -c 'sudo modprobe vcan; sudo ip link add name vcan0 type vcan; sudo ip link set dev vcan0 up'"
+   os.system(bashCommand)
+
+If it's required, the CAN interface can be set into a ``listen-only`` or ``loopback`` mode with `ip link set` commands::
+
+   ip link set vcan0 type can help  # shows additional information
+
+
+This example shows a basic functions of Linux can-utils. These utilities are handy for
+quick checks or logging.

+CANSocket python-can
+^^^^^^^^^^^^^^^^^^^^
+
+python-can is required to use various CAN-interfaces on Windows, OSX or Linux.
+The python-can library is used through a CANSocket object. To create a python-can
+CANSocket object, a python-can ``Bus`` object has to be used as interface.
+The ``timeout`` parameter can be used to increase the receive performance of a
+python-can CANSocket object. ``recv`` inside a python-can CANSocket object is
+implemented through busy wait, since there is no ``select`` functionality on
+Windows or on some proprietary CAN interfaces (like Vector interfaces). A small
+``timeout`` might be required, if a ``sniff`` or ``bridge_and_sniff`` on multiple
+interfaces is performed.
+
+Ways of creating a python-can CANSocket::
+
+   conf.contribs['CANSocket'] = {'use-python-can': True}
+   load_contrib('cansocket')
+   import can
+
+Creating a simple python-can CANSocket::
+
+   socket = CANSocket(iface=can.interface.Bus(bustype='socketcan', channel='vcan0', bitrate=250000))
+
+Creating a python-can CANSocket with multiple filters::
+
+   socket = CANSocket(iface=can.interface.Bus(bustype='socketcan', channel='vcan0', bitrate=250000,
+                   can_filters=[{'can_id': 0x200, 'can_mask': 0x7ff},
+                               {'can_id': 0x400, 'can_mask': 0x7ff},
+                               {'can_id': 0x600, 'can_mask': 0x7ff},
+                               {'can_id': 0x7ff, 'can_mask': 0x7ff}]))

+CANSocket MITM attack with bridge and sniff
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+This example shows how to use bridge and sniff on virtual CAN interfaces.
+For real world applications, use real CAN interfaces.
+Set up two vcans on Linux terminal::
+
+   sudo modprobe vcan
+   sudo ip link add name vcan0 type vcan
+   sudo ip link add name vcan1 type vcan
+   sudo ip link set dev vcan0 up
+   sudo ip link set dev vcan1 up
+
+Import modules::
+
+   import threading
+   load_contrib('cansocket')
+   load_layer("can")
+
+Create can sockets for attack::
+
+   socket0 = CANSocket(iface='vcan0')
+   socket1 = CANSocket(iface='vcan1')
+
+Create a function to send packet with threading::
+
+   def sendPacket():
+       sleep(0.2)
+       socket0.send(CAN(flags='extended', identifier=0x10010000, length=8, data=b'\x01\x02\x03\x04\x05\x06\x07\x08'))
+
+Create a function for forwarding or change packets::
+
+   def forwarding(pkt):
+       return pkt
+
+Create a function to bridge and sniff between two sockets::
+
+   def bridge():
+       bSocket0 = CANSocket(iface='vcan0')
+       bSocket1 = CANSocket(iface='vcan1')
+       bridge_and_sniff(if1=bSocket0, if2=bSocket1, xfrm12=forwarding, xfrm21=forwarding, timeout=1)
+       bSocket0.close()
+       bSocket1.close()
+
+Create threads for sending packet and to bridge and sniff::
+
+   threadBridge = threading.Thread(target=bridge)
+   threadSender = threading.Thread(target=sendMessage)
+
+Start the threads::
+
+   threadBridge.start()
+   threadSender.start()
+
+Sniff packets::
+
+   packets = socket1.sniff(timeout=0.3)
+
+Close the sockets::
+
+   socket0.close()
+   socket1.close()

+
+DBC File Format and CAN Signals
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In order to support the DBC file format, ``SignalFields`` and the ``SignalPacket``
+class were added to Scapy. ``SignalFields`` should only be used inside a ``SignalPacket``.
+Multiplexer fields (MUX) can be created through ``ConditionalFields``. The following
+example demonstrates the usage::
+
+    DBC Example:
+
+    BO_ 4 muxTestFrame: 7 TEST_ECU
+     SG_ myMuxer M : 53|3@1+ (1,0) [0|0] ""  CCL_TEST
+     SG_ muxSig4 m0 : 25|7@1- (1,0) [0|0] ""  CCL_TEST
+     SG_ muxSig3 m0 : 16|9@1+ (1,0) [0|0] ""  CCL_TEST
+     SG_ muxSig2 m0 : 15|8@0- (1,0) [0|0] ""  CCL_TEST
+     SG_ muxSig1 m0 : 0|8@1- (1,0) [0|0] ""  CCL_TEST
+     SG_ muxSig5 m1 : 22|7@1- (0.01,0) [0|0] ""  CCL_TEST
+     SG_ muxSig6 m1 : 32|9@1+ (2,10) [0|0] "mV"  CCL_TEST

+
+Scapy implementation of this DBC descriptions::

+        fields_desc = [
+            LEUnsignedSignalField("myMuxer", default=0, start=53, size=3),

+        fields_desc = [
+            LEFloatSignalField("floatSignal2", default=0, start=32),

+        ]

+
+
+
+CAN Calibration Protocol (CCP)
+------------------------------
+
+CCP is derived from CAN. The CAN-header is part of a CCP frame. CCP has two types
+of message objects. One is called Command Receive Object (CRO), the other is called
+Data Transmission Object (DTO). Usually CROs are sent to an ECU, and DTOs are received
+from an ECU. The information, if one DTO answers a CRO is implemented through a counter
+field (ctr). If both objects have the same counter value, the payload of a DTO object
+can be interpreted from the command of the associated CRO object.
+
+Creating a CRO message::
+
+    CCP(identifier=0x700)/CRO(ctr=1)/CONNECT(station_address=0x02)
+    CCP(identifier=0x711)/CRO(ctr=2)/GET_SEED(resource=2)
+    CCP(identifier=0x711)/CRO(ctr=3)/UNLOCK(key=b"123456")
+
+If we aren't interested in the DTO of an ECU, we can just send a CRO message like this:
+Sending a CRO message::
+
+    pkt = CCP(identifier=0x700)/CRO(ctr=1)/CONNECT(station_address=0x02)
+    sock = CANSocket(iface=can.interface.Bus(bustype='socketcan', channel='vcan0', bitrate=250000))
+    sock.send(pkt)
+
+If we are interested in the DTO of an ECU, we need to set the basecls parameter of the
+CANSocket to CCP and we need to use sr1:
+Sending a CRO message::
+
+    cro = CCP(identifier=0x700)/CRO(ctr=0x53)/PROGRAM_6(data=b"\x10\x11\x12\x10\x11\x12")
+    sock = CANSocket(iface=can.interface.Bus(bustype='socketcan', channel='vcan0', bitrate=250000), basecls=CCP)
+    dto = sock.sr1(cro)
+    dto.show()
+    ###[ CAN Calibration Protocol ]###
+      flags=
+      identifier= 0x700
+      length= 8
+      reserved= 0
+    ###[ DTO ]###
+         packet_id= 0xff
+         return_code= acknowledge / no error
+         ctr= 83
+    ###[ PROGRAM_6_DTO ]###
+            MTA0_extension= 2
+            MTA0_address= 0x34002006
+
+Since sr1 calls the answers function, our payload of the DTO objects gets interpreted with the
+command of our CRO object.
+
+ISOTP
+-----
+
+ISOTP message
+^^^^^^^^^^^^^
+
+Creating an ISOTP message::
+
+   load_contrib('isotp')
+   ISOTP(src=0x241, dst=0x641, data=b"\x3eabc")
+
+Creating an ISOTP message with extended addressing::
+
+   ISOTP(src=0x241, dst=0x641, exdst=0x41, data=b"\x3eabc")
+
+Creating an ISOTP message with extended addressing::
+
+   ISOTP(src=0x241, dst=0x641, exdst=0x41, exsrc=0x41, data=b"\x3eabc")
+
+Create CAN-frames from an ISOTP message::
+
+   ISOTP(src=0x241, dst=0x641, exdst=0x41, exsrc=0x55, data=b"\x3eabc" * 10).fragment()
+
+Send ISOTP message over ISOTP socket::
+
+   isoTpSocket = ISOTPSocket('vcan0', sid=0x241, did=0x641)
+   isoTpMessage = ISOTP('Message')
+   isoTpSocket.send(isoTpMessage)
+
+Sniff ISOTP message::
+
+   isoTpSocket = ISOTPSocket('vcan0', sid=0x641, did=0x241)
+   packets = isoTpSocket.sniff(timeout=0.5)
+
+ISOTP MITM attack with bridge and sniff
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Set up two vcans on Linux terminal::
+
+   sudo modprobe vcan
+   sudo ip link add name vcan0 type vcan
+   sudo ip link add name vcan1 type vcan
+   sudo ip link set dev vcan0 up
+   sudo ip link set dev vcan1 up
+
+Set up ISOTP::
+
+.. note::
+
+    First make sure you build an iso-tp kernel module.
+
+When the vcan core module is loaded with "sudo modprobe vcan" the iso-tp module can be loaded to the kernel.
+
+Therefore navigate to isotp directory, and load module with "sudo insmod ./net/can/can-isotp.ko". (Tested on Kernel 4.9.135-1-MANJARO)
+
+Detailed instructions you find in https://github.com/hartkopp/can-isotp.
+
+Import modules::
+
+   import threading
+   load_contrib('cansocket')
+   conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': True}
+   load_contrib('isotp')
+
+Create to ISOTP sockets for attack::
+
+   isoTpSocketVCan0 = ISOTPSocket('vcan0', sid=0x241, did=0x641)
+   isoTpSocketVCan1 = ISOTPSocket('vcan1', sid=0x641, did=0x241)
+
+Create function to send packet on vcan0 with threading::
+
+   def sendPacketWithISOTPSocket():
+       sleep(0.2)
+       packet = ISOTP('Request')
+       isoTpSocketVCan0.send(packet)
+
+Create function to forward packet::
+
+   def forwarding(pkt):
+       return pkt
+
+Create function to bridge and sniff between two buses::
+
+   def bridge():
+       bSocket0 = ISOTPSocket('vcan0', sid=0x641, did=0x241)
+       bSocket1 = ISOTPSocket('vcan1', sid=0x241, did=0x641)
+       bridge_and_sniff(if1=bSocket0, if2=bSocket1, xfrm12=forwarding, xfrm21=forwarding, timeout=1)
+       bSocket0.close()
+       bSocket1.close()
+
+Create threads for sending packet and to bridge and sniff::
+
+   threadBridge = threading.Thread(target=bridge)
+   threadSender = threading.Thread(target=sendPacketWithISOTPSocket)
+
+Start threads are based on Linux kernel modules. The python-can project is used to support CAN and CANSockets on other systems, besides Linux. This guide explains the hardware setup on a BeagleBone Black. The BeagleBone Black was chosen because of its two CAN interfaces on the main processor. The presence of two CAN interfaces in one device gives the possibility of CAN MITM attacks and session hijacking. The Cannelloni framework turns a BeagleBone Black into a CAN-to-UDP interface, which gives you the freedom to run Scapy on a more powerful machine.::
+
+   threadBridge.start()
+   threadSender.start()
+
+Sniff on vcan1::
+
+   receive = isoTpSocketVCan1.sniff(timeout=1)
+
+Close sockets::
+
+   isoTpSocketVCan0.close()
+   isoTpSocketVCan1.close()
+
+An ISOTPSocket will not respect ``src, dst, exdst, exsrc`` of an ISOTP message object.
+
+ISOTP Sockets
+-------------
+
+Scapy provides two kinds of ISOTP Sockets. One implementation, the ISOTPNativeSocket
+is using the Linux kernel module from Hartkopp. The other implementation, the ISOTPSoftSocket
+is completely implemented in Python. This implementation can be used on Linux,
+Windows, and OSX.
+
+ISOTPNativeSocket
+^^^^^^^^^^^^^^^^^
+
+**Requires:**
+
+* Python3
+* Linux
+* Hartkopp's Linux kernel module: ``https://github.com/hartkopp/can-isotp.git``
+
+During pentests, the ISOTPNativeSockets do have a better performance and
+reliability, usually. If you are working on Linux, consider this implementation::
+
+   conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': True}
+   load_contrib('isotp')
+   sock = ISOTPSocket("can0", sid=0x641, did=0x241)
+
+Since this implementation is using a standard Linux socket, all Scapy functions
+like ``sniff, sr, sr1, bridge_and_sniff`` work out of the box.
+
+ISOTPSoftSocket
+^^^^^^^^^^^^^^^
+
+ISOTPSoftSockets can use any CANSocket. This gives the flexibility to use all
+python-can interfaces. Additionally, these sockets work on Python2 and Python3.
+Usage on Linux with native CANSockets::
+
+   conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': False}
+   load_contrib('isotp')
+   with ISOTPSocket("can0", sid=0x641, did=0x241) as sock:
+       sock.send(...)
+
+Usage with python-can CANSockets::
+
+   conf.contribs['ISOTP'] = {'use-can-isotp-kernel-module': False}
+   conf.contribs['CANSocket'] = {'use-python-can': True}
+   load_contrib('isotp')
+   with ISOTPSocket(CANSocket(iface=python_can.interface.Bus(bustype='socketcan', channel="can0", bitrate=250000)), sid=0x641, did=0x241) as sock:
+       sock.send(...)
+
+This second example allows the usage of any ``python_can.interface`` object.
+
+**Attention:** The internal implementation of ISOTPSoftSockets requires a background
+thread. In order to be able to close this thread properly, we suggest the use of
+Pythons ``with`` statement.
+
+
+UDS
+---
+
+The main usage of UDS is flashing and diagnostic of an ECU. UDS is an
+application layer protocol and can be used as a DoIP or ENET payload or a UDS packet
+can directly be sent over an ISOTPSocket. Every OEM has its own customization of UDS.
+This increases the difficulty of generic applications and OEM specific knowledge is
+required for penetration tests. RoutineControl jobs and ReadDataByIdentifier/WriteDataByIdentifier
+services are heavily customized.
+
+Use the argument ``basecls=UDS`` on the ``init`` function of an ISOTPSocket.
+
+Here are two usage examples:
+
+.. image:: ../graphics/animations/animation-scapy-uds.svg
+.. image:: ../graphics/animations/animation-scapy-uds2.svg
+
+
+Customization of UDS_RDBI, UDS_WDBI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In real-world use-cases, the UDS layer is heavily customized. OEMs define there own substructure of packets.
+Especially the packets ReadDataByIdentifier or WriteDataByIdentifier have a very OEM or even ECU specific
+substructure. Therefore a ``StrField`` ``dataRecord`` is not added to the ``field_desc``.
+The intended usage is to create ECU or OEM specific description files, which extend the general UDS layer of
+Scapy with further protocol implementations.
+
+Customization example::
+
+    cat scapy/contrib/automotive/OEM-XYZ/car-model-xyz.py
+    #! /usr/bin/env python
+
+    # Protocol customization for car model xyz of OEM XYZ
+    # This file contains further OEM car model specific UDS additions.
+
+    from scapy.packet import Packet
+    from scapy.contrib.automotive.uds import *
+
+    # Define a new packet substructure
+
+    class DBI_IP(Packet):
+    name = 'DataByIdentifier_IP_Packet'
+    fields_desc = [
+        ByteField('ADDRESS_FORMAT_ID', 0),
+        IPField('IP', ''),
+        IPField('SUBNETMASK', ''),
+        IPField('DEFAULT_GATEWAY', '')
+    ]
+
+    # Bind the new substructure onto the existing UDS packets
+
+    bind_layers(UDS_RDBIPR, DBI_IP, dataIdentifier=0x172b)
+    bind_layers(UDS_WDBI, DBI_IP, dataIdentifier=0x172b)
+
+    # Give add a nice name to dataIdentifiers enum
+
+    UDS_RDBI.dataIdentifiers[0x172b] = 'GatewayIP'
+
+If one wants to work with this custom additions, these can be loaded at runtime to the Scapy interpreter::
+
+    >>> load_contrib("automotive.uds")
+    >>> load_contrib("automotive.OEM-XYZ.car-model-xyz")
+
+    >>> pkt = UDS()/UDS_WDBI()/DBI_IP(IP='192.168.2.1', SUBNETMASK='255.255.255.0', DEFAULT_GATEWAY='192.168.2.1')
+
+    >>> pkt.show()
+    ###[ UDS ]###
+      service= WriteDataByIdentifier
+    ###[ WriteDataByIdentifier ]###
+         dataIdentifier= GatewayIP
+         dataRecord= 0
+    ###[ DataByIdentifier_IP_Packet ]###
+            ADDRESS_FORMAT_ID= 0
+            IP= 192.168.2.1
+            SUBNETMASK= 255.255.255.0
+            DEFAULT_GATEWAY= 192.168.2.1
+
+    >>> hexdump(pkt)
+    0000  2E 17 2B 00 C0 A8 02 01 FF FF FF 00 C0 A8 02 01  ..+.............
+
+.. image:: ../graphics/animations/animation-scapy-uds3.svg
+
+GMLAN
+-----
+GMLAN is very similar to UDS. It's GMs application layer protocol for
+flashing, calibration and diagnostic of their cars.
+Use the argument ``basecls=GMLAN`` on the ``init`` function of an ISOTPSocket.
+
+Usage example:
+
+.. image:: ../graphics/animations/animation-scapy-gmlan.svg
+
+
+SOME/IP and SOME/IP SD messages
+-------------------------------
+
+Creating a SOME/IP message
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This example shows a SOME/IP message which requests a service 0x1234 with the method 0x421. Different types of SOME/IP messages follow the same procedure and their specifications can be seen here ``http://www.some-ip.com/papers/cache/AUTOSAR_TR_SomeIpExample_4.2.1.pdf``.
+
+
+Load the contribution::
+
+   load_contrib("automotive.someip")
+
+Create UDP package::
+
+   u = UDP(sport=30509, dport=30509)
+
+Create IP package::
+
+   i = IP(src="192.168.0.13", dst="192.168.0.10")
+
+Create SOME/IP package::
+
+   sip = SOMEIP()
+   sip.iface_ver = 0
+   sip.proto_ver = 1
+   sip.msg_type = "REQUEST"
+   sip.retcode = "E_OK"
+   sip.msg_id.srv_id = 0x1234
+   sip.msg_id.method_id = 0x421
+
+Add the payload::
+
+   sip.add_payload(Raw ("Hello"))
+
+Stack it and send it::
+
+   p = i/u/sip
+   send(p)
+
+
+Creating a SOME/IP SD message
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In this example a SOME/IP SD offer service message is shown with an IPv4 endpoint. Different entries and options basically follow the same procedure as shown here and can be seen at ``https://www.autosar.org/fileadmin/user_upload/standards/classic/4-3/AUTOSAR_SWS_ServiceDiscovery.pdf``.

+Load the contribution::
+
+   load_contrib("automotive.someip_sd")
+
+Create UDP package::
+
+   u = UDP(sport=30490, dport=30490)
+
+The UDP port must be the one which was chosen for the SOME/IP SD transmission.
+
+Create IP package::
+
+   i = IP(src="192.168.0.13", dst="224.224.224.245")
+
+The IP source must be from the service and the destination address needs to be the chosen multicast address.
+
+Create the entry array input::
+
+   ea = SDEntry_Service()
+
+   ea.type = 0x01
+   ea.srv_id = 0x1234
+   ea.inst_id = 0x5678
+   ea.major_ver = 0x00
+   ea.ttl = 3
+
+Create the options array input::
+
+   oa = SDOption_IP4_Endpoint()
+   oa.addr = "192.168.0.13"
+   oa.l4_proto = 0x11
+   oa.port = 30509
+
+l4_proto defines the protocol for the communication with the endpoint, UDP in this case.
+
+Create the SD package and put in the inputs::
+
+   sd = SD()
+   sd.set_entryArray(ea)
+   sd.set_optionArray(oa)
+   spsd = sd.get_someip(True)
+
+The get_someip method stacks the SOMEIP/SD message on top of a SOME/IP message, which has the desired SOME/IP values prefilled for the SOME/IP SD package transmission.
+
+Stack it and send it::
+
+   p = i/u/spsd
+   send(p)
+
+
+
+
+OBD message
+-------------
+
+OBD is implemented on top of ISOTP. Use an ISOTPSocket for the communication with a ECU. 
+You should set the parameters ``basecls=OBD`` and ``padding=True`` in your ISOTPSocket init call.
+
+OBD is split into different service groups. Here are some example requests:
+
+Request supported PIDs of service 0x01::
+
+   req = OBD()/OBD_S01(pid=[0x00])
+
+The response will contain a PacketListField, called `data_records`. This field contains the actual response::
+
+   resp = OBD()/OBD_S01_PR(data_records=[OBD_S01_PR_Record()/OBD_PID00(supported_pids=3196041235)])
+   resp.show()
+   ###[ On-board diagnostics ]###
+     service= CurrentPowertrainDiagnosticDataResponse
+   ###[ Parameter IDs ]###
+        \data_records\
+         |###[ OBD_S01_PR_Record ]###
+         |  pid= 0x0
+         |###[ PID_00_PIDsSupported ]###
+         |     supported_pids= PID20+PID1F+PID1C+PID15+PID14+PID13+PID11+PID10+PID0F+PID0E+PID0D+PID0C+PID0B+PID0A+PID07+PID06+PID05+PID04+PID03+PID01
+
+Let's assume our ECU under test supports the pid 0x15::
+   
+   req = OBD()/OBD_S01(pid=[0x15])
+   resp = sock.sr1(req)
+   resp.show()
+   ###[ On-board diagnostics ]### 
+     service= CurrentPowertrainDiagnosticDataResponse
+   ###[ Parameter IDs ]### 
+        \data_records\
+         |###[ OBD_S01_PR_Record ]###
+         |  pid= 0x15
+         |###[ PID_15_OxygenSensor2 ]### 
+         |     outputVoltage= 1.275 V
+         |     trim= 0 %
+
+
+The different services in OBD support different kinds of data. 
+Service 01 and Service 02 support Parameter Identifiers (pid).
+Service 03, 07 and 0A support Diagnostic Trouble codes (dtc).
+Service 04 doesn't require a payload.
+Service 05 is not implemented on OBD over CAN.
+Service 06 support Monitoring Identifiers (mid).
+Service 08 support Test Identifiers (tid).
+Service 09 support Information Identifiers (iid).
+
+Examples:
+^^^^^^^^^
+
+Request supported Information Identifiers::
+
+   req = OBD()/OBD_S09(iid=[0x00])
+
+Request the Vehicle Identification Number (VIN)::
+
+   req = OBD()/OBD_S09(iid=0x02)
+   resp = sock.sr1(req)
+   resp.show()
+   ###[ On-board diagnostics ]### 
+     service= VehicleInformationResponse
+   ###[ Infotype IDs ]###
+        \data_records\
+         |###[ OBD_S09_PR_Record ]###
+         |  iid= 0x2
+         |###[ IID_02_VehicleIdentificationNumber ]###
+         |     count= 1

+Test-Setup Tutorials
+--------------------
+
+Hardware Setup
+^^^^^^^^^^^^^^
+
+Beagle Bone Black Operating System Setup
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+#. | **Download an Image**
+   | The latest Debian Linux image can be found at the website
+   | ``https://beagleboard.org/latest-images``. Choose the BeagleBone
+     Black IoT version and download it.
+
+   ::
+
+       wget https://debian.beagleboard.org/images/bone-debian-8.7\
+       -iot-armhf-2017-03-19-4gb.img.xz
+
+
+   After the download, copy it to an SD-Card with minimum of 4 GB storage.
+
+   ::
+
+       xzcat bone-debian-8.7-iot-armhf-2017-03-19-4gb.img.xz | \
+       sudo dd of=/dev/xvdj
+
+
+#. | **Enable WiFi**
+   | USB-WiFi dongles are well supported by Debian Linux. Login over SSH
+     on the BBB and add the WiFi network credentials to the file
+     ``/var/lib/connman/wifi.config``. If a USB-WiFi dongle is not
+     available, it is also possible to share the host's internet
+     connection with the Ethernet connection of the BBB emulated over
+     USB. A tutorial to share the host network connection can be found
+     on this page:
+   | ``https://elementztechblog.wordpress.com/2014/12/22/sharing-internet -using-network-over-usb-in-beaglebone-black/``.
+   | Login as root onto the BBB:
+
+   ::
+
+       ssh debian@192.168.7.2
+       sudo su
+
+
+   Provide the WiFi login credentials to connman:
+
+   ::
+
+       echo "[service_home]
+       Type = wifi
+       Name = ssid
+       Security = wpa
+       Passphrase = xxxxxxxxxxxxx" \
+       > /var/lib/connman/wifi.config
+
+
+   Restart the connman service:
+
+   ::
+
+       systemctl restart connman.service
+
+
+Dual-CAN Setup
+~~~~~~~~~~~~~~
+
+#. | **Device tree setup**
+   | You'll need to follow this section only if you want to use two CAN
+    interfaces (DCAN0 and DCAN1). This will disable I2C2 from using pins
+    P9.19 and P9.20, which are needed by DCAN0. You only need to perform the
+    steps in this section once.
+
+   | Warning: The configuration in this section will disable BBB capes from
+    working. Each cape has a small I2C EEPROM that stores info that the BBB
+    needs to know in order to communicate with the cape. Disable I2C2, and
+    the BBB has no way to talk to cape EEPROMs. Of course, if you don't use
+    capes then this is not a problem.
+
+   | Acquire DTS sources that matches your kernel version. Go
+    `here <https://github.com/beagleboard/linux/>`__ and switch over to the
+    branch that represents your kernel version. Download the entire branch
+    as a ZIP file. Extract it and do the following (version 4.1 shown as an
+    example):
+
+    ::
+
+        # cd ~/src/linux-4.1/arch/arm/boot/dts/include/
+        # rm dt-bindings
+        # ln -s ../../../../../include/dt-bindings
+        # cd ..
+        Edit am335x-bone-common.dtsi and ensure the line with "//pinctrl-0 = <&i2c2_pins>;" is commented out.
+        Remove the complete &ocp section at the end of this file
+        # mv am335x-boneblack.dts am335x-boneblack.raw.dts
+        # cpp -nostdinc -I include -undef -x assembler-with-cpp am335x-boneblack.raw.dts > am335x-boneblack.dts
+        # dtc -W no-unit_address_vs_reg -O dtb -o am335x-boneblack.dtb -b 0 -@ am335x-boneblack.dts
+        # cp /boot/dtbs/am335x-boneblack.dtb /boot/dtbs/am335x-boneblack.orig.dtb
+        # cp am335x-boneblack.dtb /boot/dtbs/
+        Reboot
+
+#. **Overlay setup**
+    | This section describes how to build the device overlays for the two CAN devices (DCAN0 and DCAN1). You only need to perform the steps in this section once.
+    | Acquire BBB cape overlays, in one of two ways…
+
+    ::
+
+        # apt-get install bb-cape-overlays
+        https://github.com/beagleboard/bb.org-overlays/
+
+    | Then do the following:
+
+
+    ::
+
+        # cd ~/src/bb.org-overlays-master/src/arm
+        # ln -s ../../include
+        # mv BB-CAN1-00A0.dts BB-CAN1-00A0.raw.dts
+        # cp BB-CAN1-00A0.raw.dts BB-CAN0-00A0.raw.dts
+        Edit BB-CAN0-00A0.raw.dts and make relevant to CAN0. Example is shown below.
+        # cpp -nostdinc -I include -undef -x assembler-with-cpp BB-CAN0-00A0.raw.dts > BB-CAN0-00A0.dts
+        # cpp -nostdinc -I include -undef -x assembler-with-cpp BB-CAN1-00A0.raw.dts > BB-CAN1-00A0.dts
+        # dtc -W no-unit_address_vs_reg -O dtb -o BB-CAN0-00A0.dtbo -b 0 -@ BB-CAN0-00A0.dts
+        # dtc -W no-unit_address_vs_reg -O dtb -o BB-CAN1-00A0.dtbo -b 0 -@ BB-CAN1-00A0.dts
+        # cp *.dtbo /lib/firmware
+
+
+#. | **CAN0 Example Overlay**
+   | Inside the DTS folder, create a file with the content of the
+     following listing.

+
+
+ISO-TP Kernel Module Installation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A Linux ISO-TP kernel module can be downloaded from this website:
+``https://github.com/hartkopp/can-isotp.git``. The file
+``README.isotp`` in this repository provides all information and
+necessary steps for downloading and building this kernel module. The
+ISO-TP kernel module should also be added to the ``/etc/modules`` file,
+to load this module automatically at system boot of the BBB.
+
+CAN-Interface Setup
+~~~~~~~~~~~~~~~~~~~
+
+As the final step to prepare the BBB's CAN interfaces for usage, these
+interfaces have to be set up through some terminal commands. The bitrate
+can be chosen to fit the bitrate of a CAN bus under test.
+
+::
+
+    ip link set can0 up type can bitrate 500000
+    ip link set can1 up type can bitrate 500000
+
+Raspberry Pi SOME/IP setup
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To build a small test environment in which you can send SOME/IP messages to and from server instances or disguise yourself as a server, one Raspberry Pi, your laptop and the vsomeip library are sufficient.
+
+#. | **Download image**
+
+   Download the latest raspbian image (``https://www.raspberrypi.org/downloads/raspbian/``) and install it on the Raspberry.
+
+#. | **Vsomeip setup**
+
+   Download the vsomeip library on the Rapsberry, apply the git patch so it can work with the newer boost libraries and then install it.
+
+   ::
+
+      git clone https://github.com/GENIVI/vsomeip.git
+      cd vsomeip
+      wget -O 0001-Support-boost-v1.66.patch.zip \
+      https://github.com/GENIVI/vsomeip/files/2244890/0001-Support-boost-v1.66.patch.zip
+      unzip 0001-Support-boost-v1.66.patch.zip
+      git apply 0001-Support-boost-v1.66.patch
+      mkdir build
+      cd build
+      cmake -DENABLE_SIGNAL_HANDLING=1 ..
+      make
+      make install
+
+#. | **Make applications**
+
+   Write some small applications which function as either a service or a client and use the Scapy SOME/IP implementation to communicate with the client or the server. Examples for vsomeip applications are available on the vsomeip github wiki page (``https://github.com/GENIVI/vsomeip/wiki/vsomeip-in-10-minutes``).

+
+Software Setup
+^^^^^^^^^^^^^^
+
+Cannelloni Framework Installation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Cannelloni framework is a small application written in C++ to
+transfer CAN data over UDP. In this way, a researcher can map the CAN
+communication of a remote device to its workstation, or even combine
+multiple remote CAN devices on his machine. The framework can be
+downloaded from this website:
+``https://github.com/mguentner/cannelloni.git``. The ``README.md`` file
+explains the installation and usage in detail. Cannelloni needs virtual
+CAN interfaces on the operator's machine. The next listing shows the
+setup of virtual CAN interfaces.
+
+::
+
+    modprobe vcan
+
+    ip link add name vcan0 type vcan
+    ip link add name vcan1 type vcan
+
+    ip link set dev vcan0 up

+
+What is Bluetooth?
+==================
+
+Bluetooth is a short range, mostly point-to-point wireless communication
+protocol that operates on the 2.4GHz `ISM band`__.
+
+__ https://en.wikipedia.org/wiki/ISM_band
+
+`Bluetooth standards are publicly available`__ from the `Bluetooth Special
+Interest Group.`__
+
+__ https://www.bluetooth.com/specifications/bluetooth-core-specification
+
+__ https://www.bluetooth.com/
+
+Broadly speaking, Bluetooth has *three* distinct physical-layer protocols:
+
+Bluetooth Basic Rate (BR) and Enhanced Data Rate (EDR)
+   These are the "classic" Bluetooth physical layers.
+   
+   :abbr:`BR (Basic Rate)` reaches effective speeds of up to 721kbit/s. This was
+   ratified as ``IEEE 802.15.1-2002`` (v1.1) and ``-2005`` (v1.2).
+
+   :abbr:`EDR (Enhanced Data Rate)` was introduced as an optional feature of
+   Bluetooth 2.0 (2004). It can reach effective speeds of 2.1Mbit/s, and has
+   lower power consumption than BR.
+
+   In Bluetooth 4.0 and later, this is not supported by *Low Energy* interfaces,
+   unless they are marked as *dual-mode*.
+
+Bluetooth High Speed (HS)
+  Introduced as an optional feature of Bluetooth 3.0 (2009), this extends
+  Bluetooth by providing ``IEEE 802.11`` (WiFi) as an alternative, higher-speed
+  data transport. Nodes negotiate switching with
+  :abbr:`AMP (Alternative MAC/PHY)`.
+    
+  This is only supported by Bluetooth interfaces marked as *+HS*. Not all
+  Bluetooth 3.0 and later interfaces support it.
+
+Bluetooth Low Energy (BLE)
+  Introduced in Bluetooth 4.0	(2010), this is an alternate physical layer
+  designed for low power, embedded systems. It has shorter setup times, lower
+  data rates and smaller :abbr:`MTU (maximum transmission unit)` sizes.  It adds
+  broadcast and mesh network topologies, in addition to point-to-point links.
+
+  This is only supported by Bluetooth interface marked as *+LE* or
+  *Low Energy* -- not all Bluetooth 4.0 and later interfaces support it.
+
+Most Bluetooth interfaces on PCs use USB connectivity (even on laptops), and
+this is controlled with the Host-Controller Interface (HCI).  This typically
+doesn't support promiscuous mode (sniffing), however there are many other
+dedicated, non-HCI devices that support it.
+
+Bluetooth sockets (``AF_BLUETOOTH``)
+------------------------------------
+
+There are multiple protocols available for Bluetooth through ``AF_BLUETOOTH``
+sockets:
+
+Host-controller interface (HCI) ``BTPROTO_HCI``
+  Scapy class: ``BluetoothHCISocket``
+
+  This is the "base" level interface for communicating with a Bluetooth
+  controller.  Everything is built on top of this, and this represents about as
+  close to the physical layer as one can get with regular Bluetooth hardware.
+
+Logical Link Control and Adaptation Layer Protocol (L2CAP) ``BTPROTO_L2CAP``
+  Scapy class: ``BluetoothL2CAPSocket``
+
+  Sitting above the HCI, it provides connection and connection-less data
+  transport to higher level protocols. It provides protocol multiplexing, packet
+  segmentation and reassembly operations.
+
+  When communicating with a single device, one may use a L2CAP channel.
+
+RFCOMM ``BluetoothRFCommSocket``
+  Scapy class: ``BluetoothRFCommSocket``
+
+  RFCOMM is a serial port emulation protocol which operates over L2CAP.
+  
+  In addition to regular data transfer, it also supports manipulation of all of
+  RS-232's non-data control circuitry (:abbr:`RTS (Request To Send)`,
+  :abbr:`DTR (Data Terminal Ready)`, etc.)
+
+Bluetooth on Linux
+------------------
+
+Linux's Bluetooth stack is developed by `the BlueZ project`__. `The Linux kernel
+contains drivers to provide access to Bluetooth`__ interfaces using HCI, which
+are exposed through sockets with ``AF_BLUETOOTH``.
+
+__ http://www.bluez.org/
+
+__ https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth.git
+
+BlueZ also provides a user-space companion to these kernel interfaces. The key
+components are:
+
+``bluetoothd``
+  A daemon that provides access to Bluetooth devices over D-Bus.
+
+``bluetoothctl``
+  An interactive command-line program which interfaces with the ``bluetoothd``
+  over D-Bus.
+
+``hcitool``
+  A command-line program which interfaces directly with kernel interfaces.
+
+
+`Support for Classic Bluetooth in bluez is quite mature`__, however `BLE is
+under active development`__.

+
+First steps
+===========
+
+.. note::
+
+   You must run these examples as ``root``.  These have only been tested on
+   Linux, and require Scapy v2.4.3 or later.
+
+Verify Bluetooth device
+-----------------------
+
+Before doing anything else, you'll want to check that your Bluetooth device has
+actually been detected by the operating system:
+
+.. code-block:: console
+
+   $ hcitool dev
+   Devices:
+	   hci0	xx:xx:xx:xx:xx:xx
+
+
+.. _hci-open:
+
+Opening a HCI socket
+--------------------
+
+The first step in Scapy is to open a HCI socket to the underlying Bluetooth
+device:
+
+.. code-block:: pycon
+
+   >>> # Open a HCI socket to device hci0
+   >>> bt = BluetoothHCISocket(0)
+
+Send a control packet
+---------------------
+
+This packet contains no operation (ie: it does nothing), but it will test that
+you can communicate through the HCI device:
+
+.. code-block:: pycon
+
+   >>> ans, unans = bt.sr(HCI_Hdr()/HCI_Command_Hdr())
+   Received 1 packets, got 1 answers, remaining 0 packets
+
+You can then inspect the response:
+
+.. code-block:: pycon
+
+   >>> # ans[0] = Answered packet #0
+   >>> # ans[0][1] = The response packet
+   >>> ans[0][1]
+   >>> p.show()
+   ###[ HCI header ]###
+     type= Event
+   ###[ HCI Event header ]###
+        code= 0xf
+        len= 4
+   ###[ Command Status ]###
+           status= 1
+           number= 2
+           opcode= 0x0
+
+Receiving all events
+--------------------
+
+To start capturing all events from the HCI device, use ``sniff``:
+
+.. code-block:: pycon
+
+   >>> pkts = bt.sniff()
+   (press ^C after a few seconds to stop...)
+   >>> pkts
+   <Sniffed: TCP:0 UDP:0 ICMP:0 Other:0>
+
+Unless your computer is doing something else with Bluetooth, you'll probably get
+0 packets at this point. This is because ``sniff`` doesn't actually enable any
+promiscuous mode on the device.
+
+However, this is useful for some other commands that will be explained later on.
+
+Importing and exporting packets
+-------------------------------
+
+:ref:`Just like with other protocols <import-export>`, you can save packets for
+future use in ``libpcap`` format with ``wrpcap``:
+
+.. code-block:: pycon
+
+   >>> wrpcap("/tmp/bluetooth.pcap", pkts)
+
+And load them up again with ``rdpcap``:
+
+.. code-block:: pycon
+
+   >>> pkts = rdpcap("/tmp/bluetooth.pcap")
+
+
+Working with Bluetooth Low Energy
+=================================
+
+.. note::
+
+   This requires a Bluetooth 4.0 or later interface that supports
+   :abbr:`BLE (Bluetooth Low Energy)`, either as a dedicated
+   :abbr:`LE (Low Energy)` chipset or a *dual-mode* LE +
+   :abbr:`BR (Basic Rate)`/:abbr:`EDR (Enhanced Data Rate)` chipset (such as an
+   `RTL8723BU`__).
+   
+   These instructions only been tested on Linux, and require Scapy v2.4.3 or
+   later. There are bugs in earlier versions which decode packets incorrectly.
+
+__ https://www.realtek.com/en/products/communications-network-ics/item/rtl8723bu
+
+These examples presume you have already :ref:`opened a HCI socket <hci-open>`
+(as ``bt``).
+
+Discovering nearby devices
+--------------------------
+
+Enabling discovery mode
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Start active discovery mode with:
+
+.. code-block:: pycon
+
+   >>> # type=1: Active scanning mode
+   >>> bt.sr(
+   ...   HCI_Hdr()/
+   ...   HCI_Command_Hdr()/
+   ...   HCI_Cmd_LE_Set_Scan_Parameters(type=1))
+   Received 1 packets, got 1 answers, remaining 0 packets
+
+   >>> # filter_dups=False: Show duplicate advertising reports, because these
+   >>> # sometimes contain different data!
+   >>> bt.sr(
+   ...   HCI_Hdr()/
+   ...   HCI_Command_Hdr()/
+   ...   HCI_Cmd_LE_Set_Scan_Enable(
+   ...     enable=True,
+   ...     filter_dups=False))
+   Received 1 packets, got 1 answers, remaining 0 packets
+
+
+In the background, there are already HCI events waiting on the socket. You can
+grab these events with ``sniff``:
+
+.. code-block:: pycon
+
+   >>> # The lfilter will drop anything that's not an advertising report.
+   >>> adverts = bt.sniff(lfilter=lambda p: HCI_LE_Meta_Advertising_Reports in p)
+   (press ^C after a few seconds to stop...)
+   >>> adverts
+   <Sniffed: TCP:0 UDP:0 ICMP:0 Other:101>
+
+Once you have the packets, disable discovery mode with:
+
+.. code-block:: pycon
+
+   >>> bt.sr(
+   ...   HCI_Hdr()/
+   ...   HCI_Command_Hdr()/
+   ...   HCI_Cmd_LE_Set_Scan_Enable(
+   ...     enable=False))
+   Begin emission:
+   Finished sending 1 packets.
+   ...*
+   Received 4 packets, got 1 answers, remaining 0 packets
+   (<Results: TCP:0 UDP:0 ICMP:0 Other:1>, <Unanswered: TCP:0 UDP:0 ICMP:0 Other:0>)
+
+Collecting advertising reports
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can sometimes get multiple ``HCI_LE_Meta_Advertising_Report`` in a single
+``HCI_LE_Meta_Advertising_Reports``, and these can also be for different
+devices!
+
+.. code-block:: python3
+
+   # Rearrange into a generator that returns reports sequentially
+   from itertools import chain
+   reports = chain.from_iterable(
+     p[HCI_LE_Meta_Advertising_Reports].reports
+     for p in adverts)
+
+   # Group reports by MAC address (consumes the reports generator)
+   devices = {}
+   for report in reports:
+     device = devices.setdefault(report.addr, [])
+     device.append(report)
+
+   # Packet counters
+   devices_pkts = dict((k, len(v)) for k, v in devices.items())
+   print(devices_pkts)
+   # {'xx:xx:xx:xx:xx:xx': 408, 'xx:xx:xx:xx:xx:xx': 2}
+
+
+Filtering advertising reports
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: python3
+
+   # Get one packet for each device that broadcasted short UUID 0xfe50 (Google).
+   # Android devices broadcast this pretty much constantly.
+   google = {}
+   for mac, reports in devices.items():
+     for report in reports:
+       if (EIR_CompleteList16BitServiceUUIDs in report and
+           0xfe50 in report[EIR_CompleteList16BitServiceUUIDs].svc_uuids):
+         google[mac] = report
+         break
+
+   # List MAC addresses that sent such a broadcast
+   print(google.keys())
+   # dict_keys(['xx:xx:xx:xx:xx:xx', 'xx:xx:xx:xx:xx:xx'])
+
+Look at the first broadcast received:
+
+.. code-block:: pycon
+
+   >>> for mac, report in google.items():
+   ...   report.show()
+   ...   break
+   ...
+   ###[ Advertising Report ]###
+     type= conn_und
+     atype= random
+     addr= xx:xx:xx:xx:xx:xx
+     len= 13
+     \data\
+      |###[ EIR Header ]###
+      |  len= 2
+      |  type= flags
+      |###[ Flags ]###
+      |     flags= general_disc_mode
+      |###[ EIR Header ]###
+      |  len= 3
+      |  type= complete_list_16_bit_svc_uuids
+      |###[ Complete list of 16-bit service UUIDs ]###

+      |  len= 5
+      |  type= svc_data_16_bit_uuid
+      |###[ EIR Service Data - 16-bit UUID ]###

+
+   Changing advertisements may not take effect until advertisements have first
+   been :ref:`stopped <le-adv-stop>`.
+
+AltBeacon
+^^^^^^^^^
+
+`AltBeacon`__ is a proximity beacon protocol developed by Radius Networks.  This
+example sets up a virtual AltBeacon:
+
+__ https://github.com/AltBeacon/spec
+
+.. code-block:: python3
+
+    # Load the contrib module for AltBeacon
+    load_contrib('altbeacon')
+
+    ab = AltBeacon(
+        id1='2f234454-cf6d-4a0f-adf2-f4911ba9ffa6',
+        id2=1,
+        id3=2,
+        tx_power=-59,
+    )
+
+    bt.sr(ab.build_set_advertising_data())
+
+Once :ref:`advertising has been started <le-adv-start>`, the beacon may then be
+detected with `Beacon Locator`__ (Android).
+
+.. note::
+
+    Beacon Locator v1.2.2 `incorrectly reports the beacon as being an
+    iBeacon`__, but the values are otherwise correct.

+
+Eddystone
+^^^^^^^^^
+
+`Eddystone`__ is a proximity beacon protocol developed by Google. This uses an
+Eddystone-specific service data field.
+
+__ https://github.com/google/eddystone/
+
+This example sets up a virtual `Eddystone URL`__ beacon:

+
+.. code-block:: python3
+
+   # Load the contrib module for Eddystone
+   load_contrib('eddystone')
+
+   # Eddystone_URL.from_url() builds an Eddystone_URL frame for a given URL.
+   #
+   # build_set_advertising_data() wraps an Eddystone_Frame into a
+   # HCI_Cmd_LE_Set_Advertising_Data payload, that can be sent to the BLE
+   # controller.
+   bt.sr(Eddystone_URL.from_url(
+     'https://scapy.net').build_set_advertising_data())
+
+Once :ref:`advertising has been started <le-adv-start>`, the beacon may then be
+detected with `Eddystone Validator`__ or `Beacon Locator`__ (Android):

+Apple/iBeacon broadcast frames
+==============================
+
+.. note::
+
+    This describes the wire format for Apple's Bluetooth Low Energy
+    advertisements, based on (limited) publicly available information. It is not
+    specific to using Bluetooth on Apple operating systems.
+
+`iBeacon`__ is Apple's proximity beacon protocol. Scapy includes a contrib
+module, ``ibeacon``, for working with Apple's :abbr:`BLE (Bluetooth Low Energy)`
+broadcasts:
+
+__ https://en.wikipedia.org/wiki/IBeacon
+
+.. code-block:: pycon
+
+   >>> load_contrib('ibeacon')
+
+:ref:`Setting up advertising for iBeacon <adv-ibeacon>` (above) describes how to
+broadcast a simple beacon.
+
+While this module is called ``ibeacon``, Apple has other "submessages" which are
+also advertised within their manufacturer-specific data field, including:
+
+ * `AirDrop`__
+ * AirPlay
+ * AirPods
+ * `Handoff`__
+ * Nearby
+
+__ https://en.wikipedia.org/wiki/AirDrop
+__ https://en.wikipedia.org/wiki/OS_X_Yosemite#Continuity
+
+For compatibility with these other broadcasts, Apple BLE frames in Scapy are
+layered on top of ``Apple_BLE_Submessage`` and ``Apple_BLE_Frame``:
+
+ * ``HCI_Cmd_LE_Set_Advertising_Data``, ``HCI_LE_Meta_Advertising_Report``,
+   ``BTLE_ADV_IND``, ``BTLE_ADV_NONCONN_IND`` or ``BTLE_ADV_SCAN_IND`` contain
+   one or more...
+ * ``EIR_Hdr``, which may have a payload of one...
+ * ``EIR_Manufacturer_Specific_Data``, which may have a payload of one...
+ * ``Apple_BLE_Frame``, which contains one or more...
+ * ``Apple_BLE_Submessage``, which contains a payload of one...
+ * ``Raw`` (if not supported), or ``IBeacon_Data``.
+
+This module only presently supports ``IBeacon_Data`` submessages. Other
+submessages are decoded as ``Raw``.
+
+One might sometimes see multiple submessages in a single broadcast, such as
+Handoff and Nearby.  This is not mandatory -- there are also Handoff-only and
+Nearby-only broadcasts.
+
+Inspecting a raw BTLE advertisement frame from an Apple device:
+
+.. code-block:: python3
+
+    p = BTLE(hex_bytes('d6be898e4024320cfb574d5a02011a1aff4c000c0e009c6b8f40440f1583ec895148b410050318c0b525b8f7d4'))

+HTTP
+====
+
+Scapy supports the sending / receiving of HTTP packets natively.
+
+HTTP 1.X
+--------
+
+.. note::
+    Support for HTTP 1.X was added in ``2.4.3``, whereas HTTP 2.X was already in ``2.4.0``.
+
+About HTTP 1.X
+______________
+
+HTTP 1.X is a *text protocol*. Those are pretty unusual nowadays (HTTP 2.X is binary), therefore its implementation is very different.
+
+For transmission purposes, HTTP 1.X frames are split in various fragments during the connection, which may or not have been encoded.
+This is explain over https://developer.mozilla.org/fr/docs/Web/HTTP/Headers/Transfer-Encoding
+
+To summarize, the frames can be split in 3 different ways:
+
+- ``chunks``: split in fragments called chunks that are preceded by their length. The end of a frame is marked by an empty chunk
+- using ``Content-Length``: the header of the HTTP frame announces the total length of the frame
+- None of the above: the HTTP frame ends when the TCP stream ends / when a TCP push happens.
+
+Moreover, each frame may be aditionnally compressed, depending on the algorithm specified in the HTTP header:
+
+- ``compress``: compressed using *LZW*
+- ``deflate``: compressed using *ZLIB*
+- ``gzip``
+
+Let's have a look at what happens when you perform an HTTPRequest using Scapy's ``TCP_client`` (explained below):
+
+.. image:: ../graphics/http_tcp.png
+
+Once the first SYN/ACK is done, the connection is established. Scapy will send the ``HTTPRequest()``, and the host will answer with HTTP fragments. Scapy will ACK each of those, and recompile them using ``TCPSession``, like Wireshark does when it displays the answer frame.
+
+HTTP 1.X in Scapy
+_________________
+
+Let's list the module's content::
+
+    >>> explore(scapy.layers.http)
+    Packets contained in scapy.layers.http:

+    ------------|-------------
+    HTTP        |HTTP 1
+    HTTPRequest |HTTP Request
+    HTTPResponse|HTTP Response
+
+There are two frames available: ``HTTPRequest`` and ``HTTPResponse``. The ``HTTP`` is only used during dissection, as a util to choose between the two.
+All common header fields should be supported.
+
+- **Default HTTPRequest:**
+
+.. code:: python
+
+    >>> HTTPRequest().show()
+    ###[ HTTP Request ]###
+      Method= 'GET'
+      Path= '/'

+      Accept_Charset= None
+      Accept_Datetime= None
+      Accept_Encoding= None

+      Accept_Ranges= None
+      [...]
+
+Use Scapy to send/receive HTTP 1.X
+__________________________________
+
+To handle this decompression, Scapy uses `Sessions classes <../usage.html#advanced-sniffing-sessions>`_, more specifically the ``TCPSession`` class.
+You have several ways of using it:
+
++--------------------------------------------+-------------------------------------------+
+| ``sniff(session=TCPSession, [...])``       | ``TCP_client.tcplink(HTTP, host, 80)``    |
++============================================+===========================================+
+| | Perform decompression / defragmentation  | | Acts as a TCP client: handles SYN/ACK,  |
+| | on all TCP streams simultaneously, but   | | and all TCP actions, but only creates   |
+| | only acts passively.                     | | one stream.                             |
++--------------------------------------------+-------------------------------------------+
+
+**Examples:**
+
+- ``TCP_client.tcplink``:
+
+Send an HTTPRequest to ``www.secdev.org`` and write the result in a file:
+
+.. code:: python
+
+    load_layer("http")
+    req = HTTP()/HTTPRequest(
+        Accept_Encoding=b'gzip, deflate',
+        Cache_Control=b'no-cache',
+        Connection=b'keep-alive',
+        Host=b'www.secdev.org',
+        Pragma=b'no-cache'

+PROFINET IO RTC
+***************
+
+PROFINET IO is an industrial protocol composed of different layers such as the Real-Time Cyclic (RTC) layer, used to exchange data. However, this RTC layer is stateful and depends on a configuration sent through another layer: the DCE/RPC endpoint of PROFINET. This configuration defines where each exchanged piece of data must be located in the RTC ``data`` buffer, as well as the length of this same buffer. Building such packet is then a bit more complicated than other protocols.
+
+RTC data packet
+---------------
+
+The first thing to do when building the RTC ``data`` buffer is to instantiate each Scapy packet which represents a piece of data. Each one of them may require some specific piece of configuration, such as its length. All packets and their configuration are:
+
+* ``PNIORealTimeRawData``: a simple raw data like ``Raw``
+
+  * ``length``: defines the length of the data
+
+* ``Profisafe``: the PROFIsafe profile to perform functional safety
+
+  * ``length``: defines the length of the whole packet
+  * ``CRC``: defines the length of the CRC, either ``3`` or ``4``
+
+* ``PNIORealTimeIOxS``: either an IO Consumer or Provider Status byte
+
+  * Doesn't require any configuration
+
+To instantiate one of these packets with its configuration, the ``config`` argument must be given. It is a ``dict()`` which contains all the required piece of configuration::
+
+    >>> load_contrib('pnio_rtc')
+    >>> raw(PNIORealTimeRawData(load='AAA', config={'length': 4}))
+    'AAA\x00'
+    >>> raw(Profisafe(load='AAA', Control_Status=0x20, CRC=0x424242, config={'length': 8, 'CRC': 3}))
+    'AAA\x00 BBB'
+    >>> hexdump(PNIORealTimeIOxS())
+    0000   80                                                 .
+
+
+RTC packet
+----------
+
+Now that a data packet can be instantiated, a whole RTC packet may be built. ``PNIORealTime`` contains a field ``data`` which is a list of all data packets to add in the buffer, however, without the configuration, Scapy won't be
+able to dissect it::
+
+    >>> load_contrib("pnio_rtc")
+    >>> p=PNIORealTime(cycleCounter=1024, data=[
+    ... PNIORealTimeIOxS(),
+    ... PNIORealTimeRawData(load='AAA', config={'length':4}) / PNIORealTimeIOxS(),
+    ... Profisafe(load='AAA', Control_Status=0x20, CRC=0x424242, config={'length': 8, 'CRC': 3}) / PNIORealTimeIOxS(),
+    ... ])
+    >>> p.show()
+    ###[ PROFINET Real-Time ]### 
+      len= None
+      dataLen= None
+      \data\
+       |###[ PNIO RTC IOxS ]###

+       |     dataState= good
+       |     instance= subslot
+       |     reserved= 0x0
+       |     extension= 0
+       |###[ PROFISafe ]### 
+       |  load= 'AAA'
+       |  Control_Status= 0x20
+       |  CRC= 0x424242
+       |###[ PNIO RTC IOxS ]### 
+       |     dataState= good
+       |     instance= subslot
+       |     reserved= 0x0
+       |     extension= 0
+      padding= ''
+      cycleCounter= 1024
+      dataStatus= primary+validData+run+no_problem
+      transferStatus= 0
+    
+    >>> p.show2()
+    ###[ PROFINET Real-Time ]### 
+      len= 44
+      dataLen= 15
+      \data\
+       |###[ PNIO RTC Raw data ]### 
+       |  load= '\x80AAA\x00\x80AAA\x00 BBB\x80'
+      padding= ''
+      cycleCounter= 1024
+      dataStatus= primary+validData+run+no_problem
+      transferStatus= 0
+
+For Scapy to be able to dissect it correctly, one must also configure the layer for it to know the location of each data in the buffer. This configuration is saved in the dictionary ``conf.contribs["PNIO_RTC"]`` which can be updated with the ``pnio_update_config`` method. Each item in the dictionary uses the tuple ``(Ether.src, Ether.dst)`` as key, to be able to separate the configuration of each communication. Each value is then a list of a tuple which describes a data packet. It is composed of the negative index, from the end of the data buffer, of the packet position, the class of the packet as the second item and the ``config`` dictionary to provide to the class as last. If we continue the previous example, here is the configuration to set::
+
+    >>> load_contrib("pnio")
+    >>> e=Ether(src='00:01:02:03:04:05', dst='06:07:08:09:0a:0b') / ProfinetIO() / p

+
+If no data packets are configured for a given offset, it defaults to a ``PNIORealTimeIOxS``. However, this method is not very convenient for the user to configure the layer and it only affects the dissection of packets. In such cases, one may have access to several RTC packets, sniffed or retrieved from a PCAP file. Thus, ``PNIORealTime`` provides some methods to analyse a list of ``PNIORealTime`` packets and locate all data in it, based on simple heuristics. All of them take as first argument an iterable which contains the list of packets to analyse.
+
+* ``PNIORealTime.find_data()`` analyses the data buffer and separate real data from IOxS. It returns a dict which can be provided to ``pnio_update_config``.
+* ``PNIORealTime.find_profisafe()`` analyses the data buffer and find the PROFIsafe profiles among the real data. It returns a dict which can be provided to ``pnio_update_config``.
+* ``PNIORealTime.analyse_data()`` executes both previous methods and update the configuration. **This is usually the method to call.**
+* ``PNIORealTime.draw_entropy()`` will draw the entropy of each byte in the data buffer. It can be used to easily visualize PROFIsafe locations as entropy is the base of the decision algorithm of ``find_profisafe``.

+In addition, one can see, when displaying a ``PNIORealTime`` packet, the field ``len``. This is a computed field which is not added in the final packet build. It is mainly useful for dissection and reconstruction, but it can also be used to modify the behaviour of the packet. In fact, RTC packet must always be long enough for an Ethernet frame and to do so, a padding must be added right after the ``data`` buffer. The default behaviour is to add ``padding`` whose size is computed during the ``build`` process::
+
+    >>> raw(PNIORealTime(cycleCounter=0x4242, data=[PNIORealTimeIOxS()]))
+    '\x80\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00BB5\x00'
+
+However, one can set ``len`` to modify this behaviour. ``len`` controls the length of the whole ``PNIORealTime`` packet. Then, to shorten the length of the padding, ``len`` can be set to a lower value::
+
+    >>> raw(PNIORealTime(cycleCounter=0x4242, data=[PNIORealTimeIOxS()], len=50))
+    '\x80\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00BB5\x00'

+SCTP
+****
+
+SCTP is a relatively young transport-layer protocol combining both TCP and UDP characteristics. The `RFC 3286 <https://tools.ietf.org/html/rfc3286>`_ introduces it and its description lays in the `RFC 4960 <https://tools.ietf.org/html/rfc4960>`_.
+
+It is not broadly used, its mainly present in core networks operated by telecommunication companies, to support VoIP for instance.
+
+
+Enabling dynamic addressing reconfiguration and chunk authentication capabilities
+---------------------------------------------------------------------------------
+
+If you are trying to discuss with SCTP servers, you may be interested in capabilities added in `RFC 4895 <https://tools.ietf.org/html/rfc4895>`_ which describe how to authenticated some SCTP chunks, and/or `RFC 5061 <https://tools.ietf.org/html/rfc5061>`_ to dynamically reconfigure the IP address of a SCTP association.
+
+These capabilities are not always enabled by default on Linux. Scapy does not need any modification on its end, but SCTP servers may need specific activation.
+
+To enable the RFC 4895 about authenticating chunks::
+
+    $ sudo echo 1 > /proc/sys/net/sctp/auth_enable
+
+To enable the RFC 5061 about dynamic address reconfiguration::
+
+    $ sudo echo 1 > /proc/sys/net/sctp/addip_enable
+
+You may also want to use the dynamic address reconfiguration without necessarily enabling the chunk authentication::

+TCP
+===
+
+Scapy is based on a stimulus/response model. This model does not work

+Scapy's TCP client automaton
+----------------------------
+
+Scapy provides a simple TCP client automaton (no retransmits, no SAck,
+no timestamps, etc.). Automata can provide input and output in the shape
+of a supersocket (see `Automata's documentation`_).
+
+Here is how to use Scapy's TCP client automaton (needs at least Scapy v2.1.1).
+
+.. note::
+   
+   ``TCP_client.tcplink`` is a ``SuperSocket`` subclass, therefore all its functions (``.sniff()``, ...) are available.
+
+.. code::
+
+   >>> s = TCP_client.tcplink(Raw, "www.test.com", 80)
+   >>> s.send("GET /\r\n")
+   7
+   >>> s.recv()
+   <Raw  load='<html>\r\n<head> ... >
+
+.. note:: specifically for HTTP, you could pass ``HTTP`` instead of ``Raw``. More information over `HTTP in Scapy <http.html>`_.

+I can't sniff/inject packets in monitor mode.
+---------------------------------------------
+
+The use monitor mode varies greatly depending on the platform.
+
+- **Windows or *BSD or ``conf.use_pcap = True``**
+  ``libpcap`` must be called differently by Scapy in order for it to create the sockets in monitor mode. You will need to pass the ``monitor=True`` to any calls that open a socket (``send``, ``sniff``...) or to a Scapy socket that you create yourself (``conf.L2Socket``...)
+- **Native Linux (with pcap disabled):**
+  You should set the interface in monitor mode on your own. Scapy provides utilitary functions: ``set_iface_monitor`` and ``get_iface_mode`` (linux only), that may be used (they do system calls to ``iwconfig`` and will restart the adapter).
+
+Note that many adapters do not support monitor mode, especially on Windows, or may incorrectly report the headers. See `the Wireshark doc about this <https://wiki.wireshark.org/CaptureSetup/WLAN>`_
+
+We make our best to make this work, if your adapter works with Wireshark for instance, but not with Scapy, feel free to report an issue.
+
 My TCP connections are reset by Scapy or by my kernel.
 ------------------------------------------------------
 The kernel is not aware of what Scapy is doing behind his back. If Scapy sends a SYN, the target replies with a SYN-ACK and your kernel sees it, it will reply with a RST. To prevent this, use local firewall rules (e.g. NetFilter for Linux). Scapy does not mind about local firewalls.

+
+    DefaultTheme, BrightTheme, RastaTheme, ColorOnBlackTheme, BlackAndWhite, HTMLTheme, LatexTheme
+
+For instance::
+
+    conf.color_theme = BrightTheme()
+
+.. image:: graphics/animations/animation-scapy-themes-demo.gif
+   :align: center
+
+Other parameters such as ``conf.prompt`` can also provide some customization. Note Scapy will update the shell automatically as soon as the ``conf`` values are changed.

 Configuring super sockets
 -------------------------
 
 .. index::
    single: super socket
 
-The process of sending packets and receiving is quite complicated. As I wanted to use the PF_PACKET interface to go through netfilter, I also needed to implement an ARP stack and ARP cache, and a LL stack. Well it seems to work, on ethernet and PPP interfaces, but I don't guarantee anything. Anyway, the fact I used a kind of super-socket for that mean that you can switch your IO layer very easily, and use PF_INET/SOCK_RAW, or use PF_PACKET at level 2 (giving the LL header (ethernet,...) and giving yourself mac addresses, ...). I've just added a super socket which use libdnet and libpcap, so that it should be portable::
+Different super sockets are available in Scapy: the **native** ones, and the ones that use **libpcap** (to send/receive packets).
+
+By default, Scapy will try to use the native ones (*except on Windows, where the winpcap/npcap ones are preferred*). To manually use the **libpcap** ones, you must:
+
+* On Unix/OSX: be sure to have libpcap installed.
+* On Windows: have Npcap/Winpcap installed. (default)
 
-    >>> conf.L3socket=L3dnetSocket
-    >>> conf.L3listen=L3pcapListenSocket
+Then use::
+
+    >>> conf.use_pcap = True
+
+This will automatically update the sockets pointing to ``conf.L2socket`` and ``conf.L3socket``.
+
+If you want to manually set them, you have a bunch of sockets available, depending on your platform. For instance, you might want to use::
+
+    >>> conf.L3socket=L3pcapSocket  # Receive/send L3 packets through libpcap

+Asynchronous Sniffing
+---------------------
+
+.. index::
+   single: AsyncSniffer()
+
+.. note::
+   Asynchronous sniffing is only available since **Scapy 2.4.3**
+
+It is possible to sniff asynchronously. This allows to stop the sniffer programmatically, rather than with ctrl^C.
+It provides ``start()``, ``stop()`` and ``join()`` utils.
+
+The basic usage would be:
+
+.. code-block:: python
+
+    >>> t = AsyncSniffer()
+    >>> t.start()
+    >>> print("hey")
+    hey
+    [...]
+    >>> results = t.stop()
+
+.. image:: graphics/animations/animation-scapy-asyncsniffer.svg
+
+The ``AsyncSniffer`` class has a few useful keys, such as ``results`` (the packets collected) or ``running``, that can be used.
+It accepts the same arguments than ``sniff()`` (in fact, their implementations are merged). For instance:
+
+.. code-block:: python
+
+    >>> t = AsyncSniffer(iface="enp0s3", count=200)
+    >>> t.start()
+    >>> t.join()  # this will hold until 200 packets are collected
+    >>> results = t.results
+    >>> print(len(results))
+    200
+
+Another example: using ``prn`` and ``store=False``
+
+.. code-block:: python
+
+    >>> t = AsyncSniffer(prn=lambda x: x.summary(), store=False, filter="tcp")
+    >>> t.start()
+    >>> time.sleep(20)
+    >>> t.stop()
+
+Advanced Sniffing - Sniffing Sessions
+-------------------------------------
+
+.. note::
+   Sessions are only available since **Scapy 2.4.3**
+
+``sniff()`` also provides **Sessions**, that allows to dissect a flow of packets seamlessly. For instance, you may want your ``sniff(prn=...)`` function to automatically defragment IP packets, before executing the ``prn``.
+
+Scapy includes some basic Sessions, but it is possible to implement your own.
+Available by default:
+
+- ``IPSession`` -> *defragment IP packets* on-the-flow, to make a stream usable by ``prn``.
+- ``TCPSession`` -> *defragment certain TCP protocols**. Only **HTTP 1.0** currently uses this functionality.
+- ``NetflowSession`` -> *resolve Netflow V9 packets* from their NetflowFlowset information objects
+
+Those sessions can be used using the ``session=`` parameter of ``sniff()``. Examples::
+
+    >>> sniff(session=IPSession, iface="eth0")
+    >>> sniff(session=TCPSession, prn=lambda x: x.summary(), store=False)
+    >>> sniff(offline="file.pcap", session=NetflowSession)
+
+.. note::
+   To implement your own Session class, in order to support another flow-based protocol, start by copying a sample from `scapy/sessions.py <https://github.com/secdev/scapy/blob/master/scapy/sessions.py>`_
+   Your custom ``Session`` class only needs to extend the ``DefaultSession`` class, and implement a ``on_packet_received`` function, such as in the example.

 Moreover, Scapy normally makes sure that replies come from the same IP address the stimulus was sent to. But our DHCP packet is sent to the IP broadcast address (255.255.255.255) and any answer packet will have the IP address of the replying DHCP server as its source IP address (e.g. 192.168.1.1).

+      ``linktype``.  An unsupported ``linktype`` is replaced with ``DLT_EN10MB``
+      (Ethernet), and will display incorrectly in Wireshark.
 
+      For example, can't pass a bare :py:class:`ICMP` packet, but you can send

+Native Microsoft Windows sockets (L3 only)
+
+## Notice: ICMP packets
+
+DISCLAIMER: Please use Npcap/Winpcap to send/receive ICMP. It is going to work.
+Below is some additional information, mainly implemented in a testing purpose.
+
+When in native mode, everything goes through the Windows kernel.
+This firstly requires that the Firewall is open. Be sure it allows ICMPv4/6
+packets in and out.
+Windows may drop packets that it finds wrong. for instance, answers to
+ICMP packets with id=0 or seq=0 may be dropped. It means that sent packets
+should (most of the time) be perfectly built.
+
+A perfectly built ICMP req packet on Windows means that its id is 1, its
+checksum (IP and ICMP) are correctly built, but also that its seq number is
+in the "allowed range".
+    In fact, every time an ICMP packet is sent on Windows, a global sequence
+number is increased, which is only reset at boot time. The seq number of the
+received ICMP packet must be in the range [current, current + 3] to be valid,
+and received by the socket. The current number is quite hard to get, thus we
+provide in this module the get_actual_icmp_seq() function.
+
+Example:
+    >>> conf.use_pcap = False
+    >>> a = conf.L3socket()
+    # This will (most likely) work:
+    >>> current = get_current_icmp_seq()
+    >>> a.sr(IP(dst="www.google.com", ttl=128)/ICMP(id=1, seq=current))
+    # This won't:
+    >>> a.sr(IP(dst="www.google.com", ttl=128)/ICMP())
+
+PS: on computers where the firewall isn't open, Windows temporarily opens it
+when using the `ping` util from cmd.exe. One can first call a ping on cmd,
+then do custom calls through the socket using get_current_icmp_seq(). See
+the tests (windows.uts) for an example.

+    :description:
+
+        This module provides Scapy layers for the Intermediate System
+        to Intermediate System routing protocol as defined in RFC 1195.
+
+        Currently it (partially) supports the packaging/encoding
+        requirements of the following RFCs:
+         * RFC 1195 (only the TCP/IP related part)
+         * RFC 3358 (optional checksums)
+         * RFC 5301 (dynamic hostname extension)
+         * RFC 5302 (domain-wide prefix distribution)
+         * RFC 5303 (three-way handshake)
+         * RFC 5304 (cryptographic authentication)
+         * RFC 5308 (routing IPv6 with IS-IS)
+
+    :TODO:
+
+        - packet relations (requests, responses)
+        - support for recent RFCs:
+          * RFC 5305 (traffic engineering)
+          * RFC 5307 (support for G-MPLS)
+          * RFC 5310 (generic cryptographic authentication)
+          * RFC 5316 (inter-AS MPLS and G-MPLS TE)

+    The ISOTPSoftSocket aims to be fully compatible with the Linux ISOTP
+    sockets provided by the can-isotp kernel module, while being usable on any
+    operating system.
+    Therefore, this socket needs to be able to respond to an incoming FF frame
+    with a FC frame even before the recv() method is called.
+    A thread is needed for receiving CAN frames in the background, and since
+    the lower layer CAN implementation is not guaranteed to have a functioning
+    POSIX select(), each ISOTP socket needs its own CAN receiver thread.
+    Additionally, 2 timers are necessary to keep track of the timeouts and
+    frame separation times, and each timer is implemented in its own thread.
+    In total, each ISOTPSoftSocket spawns 3 background threads when
+    constructed, which must be terminated afterwards by calling the close()
+    method.
+    SuperSocket automatically calls the close() method when the GC destroys an
+    ISOTPSoftSocket. However, note that if any thread holds a reference to
+    an ISOTPSoftSocket object, it will not be collected by the GC.

+    ~~~~~~~~~~~~~~~
+
+    :description:
+
+        This module provides the IEC 60870-5-104 (common short name: iec104)
+        layer, the information objects and related information element
+        definitions.
+
+        normative references:
+            - IEC 60870-5-4:1994 (atomic base types / data format)
+            - IEC 60870-5-101:2003 (information elements (sec. 7.2.6) and
+              ASDU definition (sec. 7.3))
+            - IEC 60870-5-104:2006 (information element TSC (sec. 8.8, p. 44))
+
+    :TODO:
+        - add allowed direction to IO attributes
+          (but this could be derived from the name easily <--> )
+        - information elements / objects need more testing
+          (e.g. on live traffic w comparison against tshark)
+
+    :NOTES:
+        - bit and octet numbering is used as in the related standards
+          (they usually start with index one instead of zero)
+        - some of the information objects are only valid for IEC 60870-5-101 -
+          so usually they should never appear on the network as iec101 uses
+          serial connections. I added them if decoding of those messages is
+          needed cause one goes to implement a iec101<-->iec104 gateway or
+          hits such a gateway that acts not standard conform (e.g. by
+          forwarding 101 messages to a 104 network)

+
+    :NOTES:
+        - to allow Scapy to dissect this layer automatically, you need to bind the TZSP layer to UDP using  # noqa: E501
+          the default TZSP port (0x9090), e.g.
+
+            bind_layers(UDP, TZSP, sport=TZSP_PORT_DEFAULT)
+            bind_layers(UDP, TZSP, dport=TZSP_PORT_DEFAULT)
+
+        - packet format definition from www.networkchemistry.com is different from the one given by wikipedia  # noqa: E501
+        - seems Wireshark implements the wikipedia protocol version (didn't dive into their code)  # noqa: E501
+        - observed (miss)behavior of Wireshark (2.2.6)
+          - fails to decode RSSI & SNR using short values - only one byte taken
+          - SNR is labeled as silence
+          - WlanRadioHdrSerial is labeled as Sensor MAC
+          - doesn't know the packet count tag (40 / 0x28)

+            * length_from: a callback that returns the number of bytes that must be dissected by this field. The  # noqa: E501
+            callback prototype is:
+            length_from(pkt:Packet) -> int
+            * next_cls_cb: a callback that enables a Scapy developer to dynamically discover if another Packet instance  # noqa: E501
+            should be dissected or not. See below for this callback prototype.
+
+        The bytes that are not consumed during the dissection of this field are passed to the next field of the current  # noqa: E501
+        packet.
+
+        For the serialization of such a field, the list of Packets that are contained in a PacketListField can be  # noqa: E501
+        heterogeneous and is unrestricted.
+
+        The type of the Packet instances that are dissected with this field is specified or discovered using one of the  # noqa: E501
+        following mechanism:
+            * the cls parameter may contain a callable that returns an instance of the dissected Packet. This  # noqa: E501
+                may either be a reference of a Packet subclass (e.g. DNSRROPT in layers/dns.py) to generate an  # noqa: E501
+                homogeneous PacketListField or a function deciding the type of the Packet instance  # noqa: E501
+                (e.g. _CDPGuessAddrRecord in contrib/cdp.py)
+            * the cls parameter may contain a class object with a defined "dispatch_hook" classmethod. That  # noqa: E501
+                method must return a Packet instance. The dispatch_hook callmethod must implement the following prototype:  # noqa: E501
+                dispatch_hook(cls, _pkt:Optional[Packet], *args, **kargs) -> Packet_metaclass  # noqa: E501
+                The _pkt parameter may contain a reference to the packet instance containing the PacketListField that is  # noqa: E501
+                being dissected.
+            * the next_cls_cb parameter may contain a callable whose prototype is:  # noqa: E501
+                cbk(pkt:Packet, lst:List[Packet], cur:Optional[Packet], remain:str) -> Optional[Packet_metaclass]  # noqa: E501
+                The pkt argument contains a reference to the Packet instance containing the PacketListField that is  # noqa: E501
+                being dissected. The lst argument is the list of all Packet instances that were previously parsed during  # noqa: E501
+                the current PacketListField dissection, save for the very last Packet instance. The cur argument  # noqa: E501
+                contains a reference to that very last parsed Packet instance. The remain argument contains the bytes  # noqa: E501
+                that may still be consumed by the current PacketListField dissection operation. This callback returns  # noqa: E501
+                either the type of the next Packet to dissect or None to indicate that no more Packet are to be  # noqa: E501
+                dissected.
+                These four arguments allows a variety of dynamic discovery of the number of Packet to dissect and of the  # noqa: E501
+                type of each one of these Packets, including: type determination based on current Packet instances or  # noqa: E501
+                its underlayers, continuation based on the previously parsed Packet instances within that  # noqa: E501
+                PacketListField, continuation based on a look-ahead on the bytes to be dissected...  # noqa: E501
+
+        The cls and next_cls_cb parameters are semantically exclusive, although one could specify both. If both are  # noqa: E501
+        specified, cls is silently ignored. The same is true for count_from and next_cls_cb.  # noqa: E501
+        length_from and next_cls_cb are compatible and the dissection will end, whichever of the two stop conditions  # noqa: E501

+      byte order. This _changes the arrangement_ of the fields.
+
+      This format is used by Bluetooth Low Energy.
+
+    Note: You should use the constants here.
+
+    The "human encoding" of this field supports a number of different input
+    formats, and wraps Python's ``uuid.UUID`` library appropriately::
+
+    * Given a bytearray, bytes or str of 16 bytes, this class decodes UUIDs in
+      wire format.
+
+    * Given a bytearray, bytes or str of other lengths, this delegates to
+      ``uuid.UUID`` the Python standard library. This supports a number of
+      different encoding options -- see the Python standard library
+      documentation for more details.
+
+    * Given an int or long, presumed to be a 128-bit integer to pass to
+      ``uuid.UUID``.
+
+    * Given a tuple:
+
+      * Tuples of 11 integers are treated as having the last 6 integers forming
+        the ``node`` field, and are merged before being passed as a tuple of 6
+        integers to ``uuid.UUID``.
+
+      * Otherwise, the tuple is passed as the ``fields`` parameter to
+        ``uuid.UUID`` directly without modification.
+
+        ``uuid.UUID`` expects a tuple of 6 integers.
+
+    Other types (such as ``uuid.UUID``) are passed through.

+
+        Traditional payloads require registration of a Bluetooth Company ID
+        (requires company membership of the Bluetooth SIG), or a Bluetooth
+        Short UUID (requires a once-off payment).
+
+        There are alternatives which don't require registration (such as
+        128-bit UUIDs), but the biggest consumer of energy in a beacon is the
+        radio -- so the energy consumption of a beacon is proportional to the
+        number of bytes in a beacon frame.
+
+        Some beacon formats side-step this issue by using the Company ID of
+        their beacon hardware manufacturer, and adding a "magic data sequence"
+        at the start of the Manufacturer Specific Data field.
+
+        Examples of this are AltBeacon and GeoBeacon.

+         used.

+    src: the IPv6 address used as source of the packet. If None is provided,
+         an address associated with the emitting interface will be used
+         (based on the destination address of the packet).
+
+    target: the target address of the NS packet. If no value is provided,
+         a dummy address (2001:db8::1) is used. The value of the target
+         has a direct impact on the destination address of the packet if it
+         is not overridden. By default, the solicited-node multicast address
+         associated with the target is used as destination address of the
+         packet. Consider specifying a specific destination address if you
+         intend to use a target address different than the one of the victim.
+
+    dst: The destination address of the NS. By default, the solicited node
+         multicast address associated with the target address (see previous
+         parameter) is used if no specific value is provided. The victim
+         is not expected to check the destination address of the packet,
+         so using a multicast address like ff02::1 should work if you want
+         the attack to target all hosts on the link. On the contrary, if
+         you want to be more stealth, you should provide the target address
+         for this parameter in order for the packet to be sent only to the
+         victim.
+
+    src_mac: the MAC address used as source of the packet. By default, this
+         is the address of the interface. If you want to be more stealth,
+         feel free to use something else. Note that this address is not the
+         that the victim will use to populate its neighbor cache.
+
+    dst_mac: The MAC address used as destination address of the packet. If
+         the IPv6 destination address is multicast (all-nodes, solicited
+         node, ...), it will be computed. If the destination address is
+         unicast, a neighbor solicitation will be performed to get the
+         associated address. If you want the attack to be stealth, you
+         can provide the MAC address using this parameter.
+
+    loop: By default, this parameter is True, indicating that NS packets
+         will be sent in loop, separated by 'inter' seconds (see below).
+         When set to False, a single packet is sent.
 
+    inter: When loop parameter is True (the default), this parameter provides

+    #           than or equal to the product of the number of data items
+    #           and the size of a data item.  For requests the data area

+    # The version number, mode and keyid have the same function and are
+    # in the same location as a standard NTP packet.  The request packet
+    # is the same size as a standard NTP packet to ease receive buffer
+    # management, and to allow the same encryption procedure to be used
+    # both on mode 7 and standard NTP packets.  The mac is included when
+    # it is required that a request be authenticated, the keyid should be
+    # zero in requests in which the mac is not included.
+    #
+    # The data format depends on the implementation number/request code pair
+    # and whether the packet is a request or a response.  The only requirement
+    # is that data items start in the octet immediately following the size
+    # word and that data items be concatenated without padding between (i.e.
+    # if the data area is larger than data_items*size, all padding is at
+    # the end).  Padding is ignored, other than for encryption purposes.
+    # Implementations using encryption might want to include a time stamp

+CACE Per-Packet Information (PPI) header.
+
+A method for adding metadata to link-layer packets.
+
+For example, one can tag an 802.11 packet with GPS co-ordinates of where it
+was captured, and include it in the PCAP file.
+
+New PPI types should:
+
+ * Make their packet a subclass of ``PPI_Element``
+ * Call ``bind_layers(PPI_Hdr, ExamplePPI, pfh_type=0xffff)``
+
+See ``layers/contrib/ppi_cace.py`` for an example.

+6LoWPAN Protocol Stack
+======================
+
+This implementation follows the next documents:
+    * Transmission of IPv6 Packets over IEEE 802.15.4 Networks
+    * Compression Format for IPv6 Datagrams in Low Power and Lossy
+      networks (6LoWPAN): draft-ietf-6lowpan-hc-15
+    * RFC 4291
+
+                            |-----------------------|
+Application                 | Application Protocols |
+                            |-----------------------|
+Transport                   |   UDP      |   TCP    |
+                            |-----------------------|
+Network                     |          IPv6         | (Only IPv6)
+                            |-----------------------|
+                            |         LoWPAN        | (in the middle between network and data link layer)  # noqa: E501
+                            |-----------------------|
+Data Link Layer             |   IEEE 802.15.4 MAC   |
+                            |-----------------------|
+Physical                    |   IEEE 802.15.4 PHY   |
+                            |-----------------------|
+
+The Internet Control Message protocol v6 (ICMPv6) is used for control
+messaging.
+
+Adaptation between full IPv6 and the LoWPAN format is performed by routers at
+the edge of 6LoWPAN islands.
+
+A LoWPAN support addressing; a direct mapping between the link-layer address
+and the IPv6 address is used for achieving compression.
+
+
+
+Known Issues:
+    * Unimplemented context information
+    * Next header compression techniques
+    * Unimplemented LoWPANBroadcast

+Tools for handling TLS sessions and digital certificates.
+Use load_layer('tls') to load them to the main namespace.
+
+Prerequisites:
+
+    - You may need to 'pip install cryptography' for the module to be loaded.
+
+
+Main features:
+
+    - X.509 certificates parsing/building.
+
+    - RSA & ECDSA keys sign/verify methods.
+
+    - TLS records and sublayers (handshake...) parsing/building. Works with
+      versions SSLv2 to TLS 1.2. This may be enhanced by a TLS context. For
+      instance, if Scapy reads a ServerHello with version TLS 1.2 and a cipher
+      suite using AES, it will assume the presence of IVs prepending the data.
+      See test/tls.uts for real examples.
+
+    - TLS encryption/decryption capabilities with many ciphersuites, including
+      some which may be deemed dangerous. Once again, the TLS context enables
+      Scapy to transparently send/receive protected data if it learnt the
+      session secrets. Note that if Scapy acts as one side of the handshake
+      (e.g. reads all server-related packets and builds all client-related
+      packets), it will indeed compute the session secrets.
+
+    - TLS client & server basic automatons, provided for testing and tweaking
+      purposes. These make for a very primitive TLS stack.
+
+    - Additionally, a basic test PKI (key + certificate for a CA, a client and
+      a server) is provided in tls/examples/pki_test.
+
+
+Unit tests:
+
+    - Various cryptography checks.
+
+    - Reading a TLS handshake between a Firefox client and a GitHub server.
+
+    - Reading TLS 1.3 handshakes from test vectors of a draft RFC.
+
+    - Reading a SSLv2 handshake between s_client and s_server, without PFS.
+
+    - Test our TLS server against s_client with different cipher suites.
+
+    - Test our TLS client against our TLS server (s_server is unscriptable).
+
+
+TODO list (may it be carved away by good souls):
+
+    - Features to add (or wait for) in the cryptography library:
+
+        - X448 from RFC 7748 (no support in openssl yet);
+
+        - the compressed EC point format.
+
+
+    - About the automatons:
+
+        - Add resumption support, through session IDs or session tickets.
+
+        - Add various checks for discrepancies between client and server.
+          Is the ServerHello ciphersuite ok? What about the SKE params? Etc.
+
+        - Add some examples which illustrate how the automatons could be used.
+          Typically, we could showcase this with Heartbleed.
+
+        - Allow the server to store both one RSA key and one ECDSA key, and
+          select the right one to use according to the ClientHello suites.
+
+        - Find a way to shutdown the automatons sockets properly without
+          simultaneously breaking the unit tests.
+
+
+    - Miscellaneous:
+
+        - Enhance PSK and session ticket support.
+
+        - Define several Certificate Transparency objects.
+
+        - Add the extended master secret and encrypt-then-mac logic.
+
+        - Mostly unused features : DSS, fixed DH, SRP, char2 curves...

+    A simple TLS test server automaton. Try to overload some states or
+    conditions and see what happens on the other side.
+
+    Because of socket and automaton limitations, for now, the best way to
+    interrupt the server is by sending him 'stop_server'. Interruptions with
+    Ctrl-Z should work, but this might leave a loose listening socket behind.
+
+    In case the server receives a TLSAlert (whatever its type), or a 'goodbye'
+    message in a SSLv2 version, he will close the client session with a
+    similar message, and start waiting for new client connections.
+
+    _'mycert' and 'mykey' may be provided as filenames. They are needed for any
+    server authenticated handshake.
+    _'preferred_ciphersuite' allows the automaton to choose a cipher suite when
+    offered in the ClientHello. If absent, another one will be chosen.
+    _'client_auth' means the client has to provide a certificate.
+    _'is_echo_server' means that everything received will be sent back.
+    _'max_client_idle_time' is the maximum silence duration from the client.
+    Once this limit has been reached, the client (if still here) is dropped,
+    and we wait for a new connection.

+High-level methods for PKI objects (X.509 certificates, CRLs, asymmetric keys).
+Supports both RSA and ECDSA objects.
+
+The classes below are wrappers for the ASN.1 objects defined in x509.py.
+By collecting their attributes, we bypass the ASN.1 structure, hence
+there is no direct method for exporting a new full DER-encoded version
+of a Cert instance after its serial has been modified (for example).
+If you need to modify an import, just use the corresponding ASN1_Packet.
+
+For instance, here is what you could do in order to modify the serial of
+'cert' and then resign it with whatever 'key':
+    f = open('cert.der')
+    c = X509_Cert(f.read())
+    c.tbsCertificate.serialNumber = 0x4B1D
+    k = PrivKey('key.pem')
+    new_x509_cert = k.resignCert(c)
+No need for obnoxious openssl tweaking anymore. :)

+    The generic TLS Record message, based on section 6.2 of RFC 5246.
+
+    When reading a TLS message, we try to parse as much as we can.
+    In .pre_dissect(), according to the type of the current cipher algorithm
+    (self.tls_session.rcs.cipher.type), we extract the 'iv', 'mac', 'pad' and
+    'padlen'. Some of these fields may remain blank: for instance, when using
+    a stream cipher, there is no IV nor any padding. The 'len' should always
+    hold the length of the ciphered message; for the plaintext version, you
+    should rely on the additional 'deciphered_len' attribute.
+
+    XXX Fix 'deciphered_len' which should not be defined when failing with
+    AEAD decryption. This is related to the 'decryption_success' below.
+    Also, follow this behaviour in record_sslv2.py and record_tls13.py
+
+    Once we have isolated the ciphered message aggregate (which should be one
+    or several TLS messages of the same type), we try to decipher it. Either we
+    succeed and store the clear data in 'msg', or we graciously fail with a
+    CipherError and store the ciphered data in 'msg'.
+
+    Unless the user manually provides the session secrets through the passing
+    of a 'tls_session', obviously the ciphered messages will not be deciphered.
+    Indeed, the need for a proper context may also present itself when trying
+    to parse clear handshake messages.
+
+    For instance, suppose you sniffed the beginning of a DHE-RSA negotiation:
+        t1 = TLS(<client_hello>)
+        t2 = TLS(<server_hello | certificate | server_key_exchange>)
+        t3 = TLS(<server_hello | certificate | server_key_exchange>,
+                 tls_session=t1.tls_session)
+    (Note that to do things properly, here 't1.tls_session' should actually be
+    't1.tls_session.mirror()'. See session.py for explanations.)
+
+    As no context was passed to t2, neither was any client_random. Hence Scapy
+    will not be able to verify the signature of the server_key_exchange inside
+    t2. However, it should be able to do so for t3, thanks to the tls_session.
+    The consequence of not having a complete TLS context is even more obvious
+    when trying to parse ciphered content, as we described before.
+
+    Thus, in order to parse TLS-protected communications with Scapy:
+    _either Scapy reads every message from one side of the TLS connection and
+    builds every message from the other side (as such, it should know the
+    secrets needed for the generation of the pre_master_secret), while passing
+    the same tls_session context (this is how our automaton.py mostly works);
+    _or, if Scapy did not build any TLS message, it has to create a TLS context
+    and feed it with secrets retrieved by whatever technique. Note that the
+    knowing the private key of the server certificate will not be sufficient
+    if a PFS ciphersuite was used. However, if you got a master_secret somehow,
+    use it with tls_session.(w|r)cs.derive_keys() and leave the rest to Scapy.
+
+    When building a TLS message with raw_stateful, we expect the tls_session to
+    have the right parameters for ciphering. Else, .post_build() might fail.

+class connState(object):
+    """
+    From RFC 5246, section 6.1:
+    A TLS connection state is the operating environment of the TLS Record
+    Protocol.  It specifies a compression algorithm, an encryption
+    algorithm, and a MAC algorithm.  In addition, the parameters for
+    these algorithms are known: the MAC key and the bulk encryption keys
+    for the connection in both the read and the write directions.
+    Logically, there are always four connection states outstanding: the
+    current read and write states, and the pending read and write states.
+    All records are processed under the current read and write states.
+    The security parameters for the pending states can be set by the TLS
+    Handshake Protocol, and the ChangeCipherSpec can selectively make
+    either of the pending states current, in which case the appropriate
+    current state is disposed of and replaced with the pending state; the
+    pending state is then reinitialized to an empty state.  It is illegal
+    to make a state that has not been initialized with security
+    parameters a current state.  The initial current state always
+    specifies that no encryption, compression, or MAC will be used.
+
+    (For practical reasons, Scapy scraps these two last lines, through the
+    implementation of dummy ciphers and MAC with TLS_NULL_WITH_NULL_NULL.)
+
+    These attributes and behaviours are mostly mapped in this class.
+    Also, note that Scapy may make a current state out of a pending state
+    which has been initialized with dummy security parameters. We need
+    this in order to know when the content of a TLS message is encrypted,
+    whether we possess the right keys to decipher/verify it or not.
+    For instance, when Scapy parses a CKE without knowledge of any secret,
+    and then a CCS, it needs to know that the following Finished
+    is encrypted and signed according to a new cipher suite, even though
+    it cannot decipher the message nor verify its integrity.

+    Sniff packets and return a list of packets.
+
+    Args:
+        count: number of packets to capture. 0 means infinity.
+        store: whether to store sniffed packets or discard them
+        prn: function to apply to each packet. If something is returned, it
+             is displayed.
+             --Ex: prn = lambda x: x.summary()
+        session: a session = a flow decoder used to handle stream of packets.
+                 e.g: IPSession (to defragment on-the-flow) or NetflowSession
+        filter: BPF filter to apply.
+        lfilter: Python function applied to each packet to determine if
+                 further action may be done.
+                 --Ex: lfilter = lambda x: x.haslayer(Padding)
+        offline: PCAP file (or list of PCAP files) to read packets from,
+                 instead of sniffing them
+        timeout: stop sniffing after a given time (default: None).
+        L2socket: use the provided L2socket (default: use conf.L2listen).
+        opened_socket: provide an object (or a list of objects) ready to use
+                      .recv() on.
+        stop_filter: Python function applied to each packet to determine if
+                     we have to stop the capture after this packet.
+                     --Ex: stop_filter = lambda x: x.haslayer(TCP)
+        iface: interface or list of interfaces (default: None for sniffing
+               on all interfaces).
+        monitor: use monitor mode. May not be available on all OS
+        started_callback: called as soon as the sniffer starts sniffing
+                          (default: None).
+
+    The iface, offline and opened_socket parameters can be either an
+    element, a list of elements, or a dict object mapping an element to a
+    label (see examples below).
+
+    Examples: synchronous
+      >>> sniff(filter="arp")
+      >>> sniff(filter="tcp",

+
+    When using ``tcpdump`` on OSX (``prog == conf.prog.tcpdump``), this uses a
+    temporary file to store the packets. This works around a bug in Apple's
+    version of ``tcpdump``: http://apple.stackexchange.com/questions/152682/
+
+    Otherwise, the packets are passed in stdin.
+
+    This function can be explicitly enabled or disabled with the
+    ``use_tempfile`` parameter.
+
+    When using ``wireshark``, it will be called with ``-ki -`` to start
+    immediately capturing packets from stdin.
+
+    Otherwise, the command will be run with ``-r -`` (which is correct for
+    ``tcpdump`` and ``tshark``).
+
+    This can be overridden with ``read_stdin_opts``. This has no effect when
+    ``use_tempfile=True``, or otherwise reading packets from a regular file.
+
+pktlist: a Packet instance, a PacketList instance or a list of Packet
+         instances. Can also be a filename (as a string), an open
+         file-like object that must be a file format readable by
+         tshark (Pcap, PcapNg, etc.) or None (to sniff)
+
+dump:    when set to True, returns a string instead of displaying it.
+getfd:   when set to True, returns a file-like object to read data
+         from tcpdump or tshark from.
+getproc: when set to True, the subprocess.Popen object is returned
+args:    arguments (as a list) to pass to tshark (example for tshark:
+         args=["-T", "json"]).
+prog:    program to use (defaults to tcpdump, will work with tshark)
+quiet:   when set to True, the process stderr is discarded
+use_tempfile: When set to True, always use a temporary file to store packets.
+              When set to False, pipe packets through stdin.
+              When set to None (default), only use a temporary file with
+              ``tcpdump`` on OSX.
+read_stdin_opts: When set, a list of arguments needed to capture from stdin.
+                 Otherwise, attempts to guess.
+linktype: A custom DLT value or name, to overwrite the default values.
+wait: If True (default), waits for the process to terminate before returning
+      to Scapy. If False, the process will be detached to the background. If
+      dump, getproc or getfd is True, these have the same effect as
+      ``wait=False``.
