+A quick list of rules for committing stuff into netfilter git:
+
+- Always add an appropriate description, in git format
+ (i.e. first line is a summary)
+
+- Please try to include references to bugs when the description does not
+ include total discussion coverage or when the bug report is external to
+ netfilter-devel, e.g.
+ "Closes: netfilter bugzilla #123", or
+ "Reference: http://bugs.{debian,gentoo}.org/..."
+
+- If you touch any parts of libxtables (xtables.c, include/xtables.h.in),
+ make sure the so-version is updated _appropriately_ (i.e. read the
+ libtool manual about Versioning:: first, if need be) in configure.ac.
+ Adding fields to a struct always entails a vcurrent bump.
+
+ - Check, whether a bump (vcurrent,vage) has already been made since the
+ last release (no more than one per release), e.g.:
+ git log v1.4.4.. configure.ac

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, 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 Library 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.
+\f
+ 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.)
+\f
+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.
+\f
+ 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.
+\f
+ 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
+\f
+ Appendix: 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) 19yy <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., 675 Mass Ave, Cambridge, MA 02139, 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) 19yy 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 Library General
+Public License instead of this License.

+INCOMPATIBILITIES:
+
+- The REJECT target has an '--reject-with admin-prohib' option which used
+ with kernels that do not support it, will result in a plain DROP instead
+ of REJECT. Use with caution.
+ Kernels that do support it:
+ 2.4 - since 2.4.22-pre9
+ 2.6 - all
+
+- There are some issues related to upgrading from 1.2.x to 1.3.x on a system
+ with dynamic ruleset changes during runtime. (Please see
+ https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=334).
+ After upgrading from 1.2 to 1.3, it suggest go do an iptables-save, then
+ iptables-restore to ensure your dynamic rule changes continue to work.

+Installation instructions for iptables
+======================================
+
+iptables uses the well-known configure(autotools) infrastructure.
+
+ $ ./configure
+ $ make
+ # make install
+
+
+Prerequisites
+=============
+
+ * no kernel-source required
+
+ * but obviously a compiler, glibc-devel and linux-kernel-headers
+ (/usr/include/linux)
+
+
+Configuring and compiling
+=========================
+
+./configure [options]
+
+--prefix=
+
+ The prefix to put all installed files under. It defaults to
+ /usr/local, so the binaries will go into /usr/local/bin, sbin,
+ manpages into /usr/local/share/man, etc.
+
+--with-xtlibdir=
+
+ The path to where Xtables extensions should be installed to. It
+ defaults to ${prefix}/libexec/xtables.
+
+--enable-devel (or --disable-devel)
+
+ This option causes development files to be installed to
+ ${includedir}, which is needed for building additional packages,
+ such as Xtables-addons or other 3rd-party extensions.
+
+ It is enabled by default.
+
+--enable-static
+
+ Produce additional binaries, iptables-static/ip6tables-static,
+ which have all shipped extensions compiled in.
+
+--disable-shared
+
+ Produce binaries that have dynamic loading of extensions disabled.
+ This implies --enable-static.
+ (See some details below.)
+
+--enable-libipq
+
+ This option causes libipq to be installed into ${libdir} and
+ ${includedir}.
+
+--with-ksource=
+
+ Xtables does not depend on kernel headers anymore, but you can
+ optionally specify a search path to include anyway. This is
+ probably only useful for development.
+
+If you want to enable debugging, use
+
+ ./configure CFLAGS="-ggdb3 -O0"
+
+(-O0 is used to turn off instruction reordering, which makes debugging
+much easier.)
+
+
+Other notes
+===========
+
+The make process will automatically build multipurpose binaries.
+These have the core (iptables), -save, -restore and -xml code
+compiled into one binary, but extensions remain as modules.
+
+
+Static and shared
+=================
+
+Basically there are three configuration modes defined:
+
+ --disable-static --enable-shared (this is the default)
+
+ Build a binary that relies upon dynamic loading of extensions.
+
+ --enable-static --enable-shared
+
+ Build a binary that has the shipped extensions built-in, but
+ is still capable of loading additional extensions.
+
+ --enable-static --disable-shared
+
+ Shipped extensions are built-in, and dynamic loading is
+ deactivated.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures iptables 1.4.9.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+Description: administration tools for packet filtering and NAT
+ These are the user-space administration tools for the Linux
+ kernel's netfilter and iptables. netfilter and iptables provide
+ a framework for stateful and stateless packet filtering, network
+ and port address translation, and other IP packet manipulation.
+ The framework is the successor to ipchains.
+ netfilter and iptables are used in applications such as Internet
+ connection sharing, firewalls, IP accounting, transparent proxying,
+ advanced routing and traffic control.

+Turn on kernel logging of matching packets. When this option is set
+for a rule, the Linux kernel will print some information on all
+matching packets (like most IPv6 IPv6-header fields) via the kernel log
+(where it can be read with
+.I dmesg
+or
+.IR syslogd (8)).
+This is a "non-terminating target", i.e. rule traversal continues at
+the next rule. So if you want to LOG the packets you refuse, use two
+separate rules with the same matching criteria, first using target LOG
+then DROP (or REJECT).

+\fB\-\-log\-level\fP \fIlevel\fP

+\fB\-\-log\-prefix\fP \fIprefix\fP
+Prefix log messages with the specified prefix; up to 29 letters long,
+and useful for distinguishing messages in the logs.
+.TP
+\fB\-\-log\-tcp\-sequence\fP

+This target is only valid in the
+.B nat
+table, in the
+.B PREROUTING
+and
+.B OUTPUT
+chains, and user-defined chains which are only called from those
+chains. It specifies that the destination address of the packet
+should be modified (and all future packets in this connection will
+also be mangled), and rules should cease being examined. It takes one
+type of option:
+.TP
+\fB\-\-to\-destination\fP [\fIipaddr\fP][\fB\-\fP\fIipaddr\fP][\fB:\fP\fIport\fP[\fB\-\fP\fIport\fP]]
+which can specify a single new destination IP address, an inclusive
+range of IP addresses, and optionally, a port range (which is only
+valid if the rule also specifies
+\fB\-p tcp\fP
+or
+\fB\-p udp\fP).
+If no port range is specified, then the destination port will never be
+modified. If no IP address is specified then only the destination port
+will be modified.
+
+In Kernels up to 2.6.10 you can add several \-\-to\-destination options. For
+those kernels, if you specify more than one destination address, either via an
+address range or multiple \-\-to\-destination options, a simple round-robin (one
+after another in cycle) load balancing takes place between these addresses.
+Later Kernels (>= 2.6.11-rc1) don't have the ability to NAT to multiple ranges
+anymore.
+.TP
+\fB\-\-random\fP
+If option
+\fB\-\-random\fP
+is used then port mapping will be randomized (kernel >= 2.6.22).
+.TP
+\fB\-\-persistent\fP
+Gives a client the same source-/destination-address for each connection.
+This supersedes the SAME target. Support for persistent mappings is available
+from 2.6.29-rc2.

+This target provides userspace logging of matching packets. When this

+through a
+.IR netlink
+socket. One or more userspace processes may then subscribe to various
+multicast groups and receive the packets.
+Like LOG, this is a "non-terminating target", i.e. rule traversal
+continues at the next rule.
+.TP
+\fB\-\-ulog\-nlgroup\fP \fInlgroup\fP
+This specifies the netlink group (1-32) to which the packet is sent.
+Default value is 1.
+.TP
+\fB\-\-ulog\-prefix\fP \fIprefix\fP
+Prefix log messages with the specified prefix; up to 32 characters
+long, and useful for distinguishing messages in the logs.
+.TP
+\fB\-\-ulog\-cprange\fP \fIsize\fP
+Number of bytes to be copied to userspace. A value of 0 always copies
+the entire packet, regardless of its size. Default is 0.
+.TP
+\fB\-\-ulog\-qthreshold\fP \fIsize\fP
+Number of packet to queue inside kernel. Setting this value to, e.g. 10
+accumulates ten packets inside the kernel and transmits them as one
+netlink multipart message to userspace. Default is 1 (for backwards
+compatibility).

+This module matches packets based on their
+.B address type.
+Address types are used within the kernel networking stack and categorize
+addresses into various groups. The exact definition of that group depends on the specific layer three protocol.
+.PP
+The following address types are possible:
+.TP
+.BI "UNSPEC"
+an unspecified address (i.e. 0.0.0.0)
+.TP
+.BI "UNICAST"
+an unicast address
+.TP
+.BI "LOCAL"
+a local address
+.TP
+.BI "BROADCAST"
+a broadcast address
+.TP
+.BI "ANYCAST"
+an anycast packet
+.TP
+.BI "MULTICAST"
+a multicast address
+.TP
+.BI "BLACKHOLE"
+a blackhole address
+.TP
+.BI "UNREACHABLE"
+an unreachable address
+.TP
+.BI "PROHIBIT"
+a prohibited address
+.TP
+.BI "THROW"
+FIXME
+.TP
+.BI "NAT"
+FIXME
+.TP
+.BI "XRESOLVE"
+.TP
+[\fB!\fP] \fB\-\-src\-type\fP \fItype\fP
+Matches if the source address is of given type
+.TP
+[\fB!\fP] \fB\-\-dst\-type\fP \fItype\fP
+Matches if the destination address is of given type
+.TP
+.BI "\-\-limit\-iface\-in"
+The address type checking can be limited to the interface the packet is coming
+in. This option is only valid in the
+.BR PREROUTING ,
+.B INPUT
+and
+.B FORWARD
+chains. It cannot be specified with the
+\fB\-\-limit\-iface\-out\fP
+option.
+.TP
+\fB\-\-limit\-iface\-out\fP
+The address type checking can be limited to the interface the packet is going
+out. This option is only valid in the

+This creates an LED-trigger that can then be attached to system indicator
+lights, to blink or illuminate them when certain packets pass through the
+system. One example might be to light up an LED for a few minutes every time
+an SSH connection is made to the local machine. The following options control
+the trigger behavior:
+.TP
+\fB\-\-led\-trigger\-id\fP \fIname\fP
+This is the name given to the LED trigger. The actual name of the trigger
+will be prefixed with "netfilter-".
+.TP
+\fB\-\-led-delay\fP \fIms\fP
+This indicates how long (in milliseconds) the LED should be left illuminated
+when a packet arrives before being switched off again. The default is 0
+(blink as fast as possible.) The special value \fIinf\fP can be given to
+leave the LED on permanently once activated. (In this case the trigger will
+need to be manually detached and reattached to the LED device to switch it
+off again.)
+.TP
+\fB\-\-led\-always\-blink\fP
+Always make the LED blink on packet arrival, even if the LED is already on.
+This allows notification of new packets even with long delay values (which
+otherwise would result in a silent prolonging of the delay time.)
+.TP
+Example:
+.TP
+Create an LED trigger for incoming SSH traffic:
+iptables \-A INPUT \-p tcp \-\-dport 22 \-j LED \-\-led\-trigger\-id ssh
+.TP
+Then attach the new trigger to an LED:
+echo netfilter\-ssh >/sys/class/leds/\fIledname\fP/trigger

--- /dev/null
+This target provides logging of matching packets. When this target is
+set for a rule, the Linux kernel will pass the packet to the loaded
+logging backend to log the packet. This is usually used in combination
+with nfnetlink_log as logging backend, which will multicast the packet
+through a
+.IR netlink
+socket to the specified multicast group. One or more userspace processes
+may subscribe to the group to receive the packets. Like LOG, this is a
+non-terminating target, i.e. rule traversal continues at the next rule.
+.TP
+\fB\-\-nflog\-group\fP \fInlgroup\fP
+The netlink group (1 \- 2^32\-1) to which packets are (only applicable for
+nfnetlink_log). The default value is 0.
+.TP
+\fB\-\-nflog\-prefix\fP \fIprefix\fP
+A prefix string to include in the log message, up to 64 characters
+long, useful for distinguishing messages in the logs.
+.TP
+\fB\-\-nflog\-range\fP \fIsize\fP
+The number of bytes to be copied to userspace (only applicable for
+nfnetlink_log). nfnetlink_log instances may specify their own
+range, this option overrides it.
+.TP
+\fB\-\-nflog\-threshold\fP \fIsize\fP
+Number of packets to queue inside the kernel before sending them
+to userspace (only applicable for nfnetlink_log). Higher values
+result in less overhead per packet, but increase delay until the
+packets reach userspace. The default value is 1.

+This target allows to alter the MSS value of TCP SYN packets, to control
+the maximum size for that connection (usually limiting it to your
+outgoing interface's MTU minus 40 for IPv4 or 60 for IPv6, respectively).
+Of course, it can only be used
+in conjunction with
+\fB\-p tcp\fP.
+.PP
+This target is used to overcome criminally braindead ISPs or servers
+which block "ICMP Fragmentation Needed" or "ICMPv6 Packet Too Big"
+packets. The symptoms of this
+problem are that everything works fine from your Linux
+firewall/router, but machines behind it can never exchange large
+packets:
+.PD 0
+.RS 0.1i
+.TP 0.3i
+1)
+Web browsers connect, then hang with no data received.
+.TP
+2)
+Small mail works fine, but large emails hang.
+.TP
+3)
+ssh works fine, but scp hangs after initial handshaking.
+.RE
+.PD
+Workaround: activate this option and add a rule to your firewall
+configuration like:
+.IP
+ iptables \-t mangle \-A FORWARD \-p tcp \-\-tcp\-flags SYN,RST SYN
+ \-j TCPMSS \-\-clamp\-mss\-to\-pmtu
+.TP
+\fB\-\-set\-mss\fP \fIvalue\fP
+Explicitly sets MSS option to specified value. If the MSS of the packet is
+already lower than \fIvalue\fP, it will \fBnot\fP be increased (from Linux
+2.6.25 onwards) to avoid more problems with hosts relying on a proper MSS.
+.TP
+\fB\-\-clamp\-mss\-to\-pmtu\fP
+Automatically clamp MSS value to (path_MTU \- 40 for IPv4; \-60 for IPv6).
+This may not function as desired where asymmetric routes with differing
+path MTU exist \(em the kernel uses the path MTU which it would use to send
+packets from itself to the source and destination IP addresses. Prior to
+Linux 2.6.25, only the path MTU to the destination IP address was
+considered by this option; subsequent kernels also consider the path MTU
+to the source IP address.
+.PP
+These options are mutually exclusive.

+This target is only valid in the \fBmangle\fR table, in the \fBPREROUTING\fR
+chain and user-defined chains which are only called from this chain. It
+redirects the packet to a local socket without changing the packet header in
+any way. It can also change the mark value which can then be used in advanced
+routing rules.
+It takes three options:
+.TP
+\fB\-\-on\-port\fP \fIport\fP
+This specifies a destination port to use. It is a required option, 0 means the
+new destination port is the same as the original. This is only valid if the
+rule also specifies \fB\-p tcp\fP or \fB\-p udp\fP.
+.TP
+\fB\-\-on\-ip\fP \fIaddress\fP
+This specifies a destination address to use. By default the address is the IP
+address of the incoming interface. This is only valid if the rule also
+specifies \fB\-p tcp\fP or \fB\-p udp\fP.
+.TP
+\fB\-\-tproxy\-mark\fP \fIvalue\fP[\fB/\fP\fImask\fP]
+Marks packets with the given value/mask. The fwmark value set here can be used
+by advanced routing. (Required for transparent proxying to work: otherwise
+these packets will get forwarded, which is probably not what you want.)

+\fBhashlimit\fR uses hash buckets to express a rate limiting match (like the
+\fBlimit\fR match) for a group of connections using a \fBsingle\fR iptables
+rule. Grouping can be done per-hostgroup (source and/or destination address)
+and/or per-port. It gives you the ability to express "\fIN\fR packets per time
+quantum per group":
+.TP
+matching on source host
+"1000 packets per second for every host in 192.168.0.0/16"
+.TP

+.TP
+matching on subnet
+"10000 packets per minute for every /28 subnet in 10.0.0.0/8"
+.PP
+A hash limit option (\fB\-\-hashlimit\-upto\fP, \fB\-\-hashlimit\-above\fP) and
+\fB\-\-hashlimit\-name\fP are required.
+.TP
+\fB\-\-hashlimit\-upto\fP \fIamount\fP[\fB/second\fP|\fB/minute\fP|\fB/hour\fP|\fB/day\fP]
+Match if the rate is below or equal to \fIamount\fR/quantum. It is specified as
+a number, with an optional time quantum suffix; the default is 3/hour.
+.TP
+\fB\-\-hashlimit\-above\fP \fIamount\fP[\fB/second\fP|\fB/minute\fP|\fB/hour\fP|\fB/day\fP]
+Match if the rate is above \fIamount\fR/quantum.

+A comma-separated list of objects to take into consideration. If no
+\-\-hashlimit\-mode option is given, hashlimit acts like limit, but at the

+.TP
+\fB\-\-hashlimit\-srcmask\fP \fIprefix\fP
+When \-\-hashlimit\-mode srcip is used, all source addresses encountered will be
+grouped according to the given prefix length and the so-created subnet will be
+subject to hashlimit. \fIprefix\fR must be between (inclusive) 0 and 32. Note
+that \-\-hashlimit\-srcmask 0 is basically doing the same thing as not specifying
+srcip for \-\-hashlimit\-mode, but is technically more expensive.

+\fB\-\-hashlimit\-dstmask\fP \fIprefix\fP
+Like \-\-hashlimit\-srcmask, but for destination addresses.

+\fB\-\-hashlimit\-htable\-size\fP \fIbuckets\fP
+The number of buckets of the hash table
+.TP
+\fB\-\-hashlimit\-htable\-max\fP \fIentries\fP
+Maximum entries in the hash.

+This module matches a set of source or destination ports. Up to 15
+ports can be specified. A port range (port:port) counts as two
+ports. It can only be used in conjunction with
+\fB\-p tcp\fP
+or
+\fB\-p udp\fP.
+.TP

+Match if the source port is one of the given ports. The flag
+\fB\-\-sports\fP
+is a convenient alias for this option. Multiple ports or port ranges are
+separated using a comma, and a port range is specified using a colon.
+\fB53,1024:65535\fP would therefore match ports 53 and all from 1024 through
+65535.

+The osf module does passive operating system fingerprinting. This modules
+compares some data (Window Size, MSS, options and their order, TTL, DF,
+and others) from packets with the SYN bit set.
+.TP
+[\fB!\fP] \fB\-\-genre\fP \fIstring\fP
+Match an operating system genre by using a passive fingerprinting.
+.TP
+\fB\-\-ttl\fP \fIlevel\fP
+Do additional TTL checks on the packet to determine the operating system.
+\fIlevel\fP can be one of the following values:
+.IP \(bu 4
+0 - True IP address and fingerprint TTL comparison. This generally works for
+LANs.
+.IP \(bu 4
+1 - Check if the IP header's TTL is less than the fingerprint one. Works for
+globally-routable addresses.
+.IP \(bu 4
+2 - Do not compare the TTL at all.
+.TP
+\fB\-\-log\fP \fIlevel\fP
+Log determined genres into dmesg even if they do not match the desired one.
+\fIlevel\fP can be one of the following values:
+.IP \(bu 4
+0 - Log all matched or unknown signatures
+.IP \(bu 4
+1 - Log only the first one
+.IP \(bu 4
+2 - Log all known matched signatures
+.PP
+You may find something like this in syslog:
+.PP
+Windows [2000:SP3:Windows XP Pro SP1, 2000 SP3]: 11.22.33.55:4024 ->
+11.22.33.44:139 hops=3 Linux [2.5-2.6:] : 1.2.3.4:42624 -> 1.2.3.5:22 hops=4
+.PP
+OS fingerprints are loadable using the \fBnfnl_osf\fP program. To load
+fingerprints from a file, use:
+.PP
+\fBnfnl_osf -f /usr/share/xtables/pf.os\fP
+.PP
+To remove them again,
+.PP
+\fBnfnl_osf -f /usr/share/xtables/pf.os -d\fP
+.PP
+The fingerprint database can be downlaoded from
+http://www.openbsd.org/cgi-bin/cvsweb/src/etc/pf.os .

--- /dev/null
+Allows you to dynamically create a list of IP addresses and then match against
+that list in a few different ways.
+.PP
+For example, you can create a "badguy" list out of people attempting to connect
+to port 139 on your firewall and then DROP all future packets from them without
+considering them.
+.PP
+\fB\-\-set\fP, \fB\-\-rcheck\fP, \fB\-\-update\fP and \fB\-\-remove\fP are
+mutually exclusive.
+.TP
+\fB\-\-name\fP \fIname\fP
+Specify the list to use for the commands. If no name is given then
+\fBDEFAULT\fR will be used.
+.TP
+[\fB!\fR] \fB\-\-set\fP
+This will add the source address of the packet to the list. If the source
+address is already in the list, this will update the existing entry. This will
+always return success (or failure if \fB!\fR is passed in).
+.TP
+\fB\-\-rsource\fP
+Match/save the source address of each packet in the recent list table. This
+is the default.
+.TP
+\fB\-\-rdest\fP
+Match/save the destination address of each packet in the recent list table.
+.TP
+[\fB!\fR] \fB\-\-rcheck\fP
+Check if the source address of the packet is currently in the list.
+.TP
+[\fB!\fR] \fB\-\-update\fP
+Like \fB\-\-rcheck\fP, except it will update the "last seen" timestamp if it
+matches.
+.TP
+[\fB!\fR] \fB\-\-remove\fP
+Check if the source address of the packet is currently in the list and if so
+that address will be removed from the list and the rule will return true. If
+the address is not found, false is returned.
+.TP
+\fB\-\-seconds\fP \fIseconds\fP
+This option must be used in conjunction with one of \fB\-\-rcheck\fP or
+\fB\-\-update\fP. When used, this will narrow the match to only happen when the
+address is in the list and was seen within the last given number of seconds.
+.TP
+\fB\-\-hitcount\fP \fIhits\fP
+This option must be used in conjunction with one of \fB\-\-rcheck\fP or
+\fB\-\-update\fP. When used, this will narrow the match to only happen when the
+address is in the list and packets had been received greater than or equal to
+the given value. This option may be used along with \fB\-\-seconds\fP to create
+an even narrower match requiring a certain number of hits within a specific
+time frame. The maximum value for the hitcount parameter is given by the
+"ip_pkt_list_tot" parameter of the xt_recent kernel module. Exceeding this
+value on the command line will cause the rule to be rejected.
+.TP
+\fB\-\-rttl\fP
+This option may only be used in conjunction with one of \fB\-\-rcheck\fP or
+\fB\-\-update\fP. When used, this will narrow the match to only happen when the
+address is in the list and the TTL of the current packet matches that of the
+packet which hit the \fB\-\-set\fP rule. This may be useful if you have problems
+with people faking their source address in order to DoS you via this module by
+disallowing others access to your site by sending bogus packets to you.
+.PP
+Examples:
+.IP
+iptables \-A FORWARD \-m recent \-\-name badguy \-\-rcheck \-\-seconds 60 \-j DROP
+.IP
+iptables \-A FORWARD \-p tcp \-i eth0 \-\-dport 139 \-m recent \-\-name badguy \-\-set \-j DROP
+.PP
+Steve's ipt_recent website (http://snowman.net/projects/ipt_recent/) also has
+some examples of usage.
+.PP
+\fB/proc/net/xt_recent/*\fR are the current lists of addresses and information
+about each entry of each list.
+.PP
+Each file in \fB/proc/net/xt_recent/\fR can be read from to see the current
+list or written two using the following commands to modify the list:
+.TP
+\fBecho +\fR\fIaddr\fR\fB >/proc/net/xt_recent/DEFAULT\fR
+to add \fIaddr\fR to the DEFAULT list
+.TP
+\fBecho \-\fP\fIaddr\fP\fB >/proc/net/xt_recent/DEFAULT\fP
+to remove \fIaddr\fR from the DEFAULT list
+.TP
+\fBecho / >/proc/net/xt_recent/DEFAULT\fR
+to flush the DEFAULT list (remove all entries).
+.PP
+The module itself accepts parameters, defaults shown:
+.TP
+\fBip_list_tot\fR=\fI100\fR
+Number of addresses remembered per table.
+.TP
+\fBip_pkt_list_tot\fR=\fI20\fR
+Number of packets per address remembered.
+.TP
+\fBip_list_hash_size\fR=\fI0\fR
+Hash table size. 0 means to calculate it based on ip_list_tot, default: 512.
+.TP
+\fBip_list_perms\fR=\fI0644\fR
+Permissions for /proc/net/xt_recent/* files.
+.TP
+\fBip_list_uid\fR=\fI0\fR
+Numerical UID for ownership of /proc/net/xt_recent/* files.
+.TP
+\fBip_list_gid\fR=\fI0\fR
+Numerical GID for ownership of /proc/net/xt_recent/* files.

+will match packets, for which (if the set type is ipportmap) the source

+Use of -m set requires that ipset kernel support is provided. As standard

+It supports two distinct modes settable with the
+\fB\-\-mode\fP
+option.
+.PP
+Supported options:
+.TP
+\fB\-\-mode\fP \fImode\fP
+Set the matching mode of the matching rule, supported modes are
+.B random
+and
+.B nth.
+.TP
+\fB\-\-probability\fP \fIp\fP
+Set the probability from 0 to 1 for a packet to be randomly
+matched. It works only with the
+.B random
+mode.
+.TP
+\fB\-\-every\fP \fIn\fP
+Match one packet every nth packet. It works only with the
+.B nth
+mode (see also the
+\fB\-\-packet\fP
+option).
+.TP
+\fB\-\-packet\fP \fIp\fP
+Set the initial counter value (0 <= p <= n\-1, default 0) for the
+.B nth
+mode.

+/* Shared library add-on to iptables to add string matching support.
+ *
+ * Copyright (C) 2000 Emmanuel Roger <winfield@freegates.be>
+ *
+ * 2005-08-05 Pablo Neira Ayuso <pablo@eurodev.net>
+ * - reimplemented to use new string matching iptables match
+ * - add functionality to match packets by using window offsets
+ * - add functionality to select the string matching algorithm
+ *
+ * ChangeLog
+ * 29.12.2003: Michael Rash <mbr@cipherdyne.org>
+ * Fixed iptables save/restore for ascii strings
+ * that contain space chars, and hex strings that
+ * contain embedded NULL chars. Updated to print
+ * strings in hex mode if any non-printable char
+ * is contained within the string.
+ *
+ * 27.01.2001: Gianni Tedesco <gianni@ecsc.co.uk>
+ * Changed --tos to --string in save(). Also
+ * updated to work with slightly modified
+ * ipt_string_info.

+These extensions can be used if `\-\-protocol tcp' is specified. It
+provides the following options:
+.TP
+[\fB!\fP] \fB\-\-source\-port\fP,\fB\-\-sport\fP \fIport\fP[\fB:\fP\fIport\fP]
+Source port or port range specification. This can either be a service
+name or a port number. An inclusive range can also be specified,
+using the format \fIfirst\fP\fB:\fP\fIlast\fP.
+If the first port is omitted, "0" is assumed; if the last is omitted,
+"65535" is assumed.
+If the first port is greater than the second one they will be swapped.
+The flag
+\fB\-\-sport\fP
+is a convenient alias for this option.
+.TP
+[\fB!\fP] \fB\-\-destination\-port\fP,\fB\-\-dport\fP \fIport\fP[\fB:\fP\fIport\fP]
+Destination port or port range specification. The flag
+\fB\-\-dport\fP
+is a convenient alias for this option.
+.TP
+[\fB!\fP] \fB\-\-tcp\-flags\fP \fImask\fP \fIcomp\fP
+Match when the TCP flags are as specified. The first argument \fImask\fP is the
+flags which we should examine, written as a comma-separated list, and
+the second argument \fIcomp\fP is a comma-separated list of flags which must be
+set. Flags are:
+.BR "SYN ACK FIN RST URG PSH ALL NONE" .
+Hence the command
+.nf
+ iptables \-A FORWARD \-p tcp \-\-tcp\-flags SYN,ACK,FIN,RST SYN
+.fi
+will only match packets with the SYN flag set, and the ACK, FIN and
+RST flags unset.
+.TP
+[\fB!\fP] \fB\-\-syn\fP
+Only match TCP packets with the SYN bit set and the ACK,RST and FIN bits
+cleared. Such packets are used to request TCP connection initiation;
+for example, blocking such packets coming in an interface will prevent
+incoming TCP connections, but outgoing TCP connections will be
+unaffected.
+It is equivalent to \fB\-\-tcp\-flags SYN,RST,ACK,FIN SYN\fP.
+If the "!" flag precedes the "\-\-syn", the sense of the
+option is inverted.
+.TP
+[\fB!\fP] \fB\-\-tcp\-option\fP \fInumber\fP
+Match if TCP option set.

+U32 tests whether quantities of up to 4 bytes extracted from a packet have
+specified values. The specification of what to extract is general enough to
+find data at given offsets from tcp headers or payloads.
+.TP
+[\fB!\fP] \fB\-\-u32\fP \fItests\fP
+The argument amounts to a program in a small language described below.
+.IP
+tests := location "=" value | tests "&&" location "=" value
+.IP
+value := range | value "," range
+.IP
+range := number | number ":" number
+.PP
+a single number, \fIn\fR, is interpreted the same as \fIn:n\fR. \fIn:m\fR is
+interpreted as the range of numbers \fB>=n\fR and \fB<=m\fR.
+.IP "" 4
+location := number | location operator number
+.IP "" 4
+operator := "&" | "<<" | ">>" | "@"
+.PP
+The operators \fB&\fR, \fB<<\fR, \fB>>\fR and \fB&&\fR mean the same as in C.
+The \fB=\fR is really a set membership operator and the value syntax describes
+a set. The \fB@\fR operator is what allows moving to the next header and is
+described further below.
+.PP
+There are currently some artificial implementation limits on the size of the
+tests:
+.IP " *"
+no more than 10 of "\fB=\fR" (and 9 "\fB&&\fR"s) in the u32 argument
+.IP " *"
+no more than 10 ranges (and 9 commas) per value
+.IP " *"
+no more than 10 numbers (and 9 operators) per location
+.PP
+To describe the meaning of location, imagine the following machine that
+interprets it. There are three registers:
+.IP
+A is of type \fBchar *\fR, initially the address of the IP header
+.IP
+B and C are unsigned 32 bit integers, initially zero
+.PP
+The instructions are:
+.IP
+number B = number;
+.IP
+C = (*(A+B)<<24) + (*(A+B+1)<<16) + (*(A+B+2)<<8) + *(A+B+3)
+.IP
+&number C = C & number
+.IP
+<< number C = C << number
+.IP
+>> number C = C >> number
+.IP
+@number A = A + C; then do the instruction number
+.PP
+Any access of memory outside [skb\->data,skb\->end] causes the match to fail.
+Otherwise the result of the computation is the final value of C.
+.PP
+Whitespace is allowed but not required in the tests. However, the characters
+that do occur there are likely to require shell quoting, so it is a good idea
+to enclose the arguments in quotes.
+.PP
+Example:
+.IP
+match IP packets with total length >= 256
+.IP
+The IP header contains a total length field in bytes 2-3.
+.IP
+\-\-u32 "\fB0 & 0xFFFF = 0x100:0xFFFF\fP"
+.IP
+read bytes 0-3
+.IP
+AND that with 0xFFFF (giving bytes 2-3), and test whether that is in the range
+[0x100:0xFFFF]
+.PP
+Example: (more realistic, hence more complicated)
+.IP
+match ICMP packets with icmp type 0
+.IP
+First test that it is an ICMP packet, true iff byte 9 (protocol) = 1
+.IP
+\-\-u32 "\fB6 & 0xFF = 1 &&\fP ...
+.IP
+read bytes 6-9, use \fB&\fR to throw away bytes 6-8 and compare the result to
+1. Next test that it is not a fragment. (If so, it might be part of such a
+packet but we cannot always tell.) N.B.: This test is generally needed if you
+want to match anything beyond the IP header. The last 6 bits of byte 6 and all
+of byte 7 are 0 iff this is a complete packet (not a fragment). Alternatively,
+you can allow first fragments by only testing the last 5 bits of byte 6.
+.IP
+ ... \fB4 & 0x3FFF = 0 &&\fR ...
+.IP
+Last test: the first byte past the IP header (the type) is 0. This is where we
+have to use the @syntax. The length of the IP header (IHL) in 32 bit words is
+stored in the right half of byte 0 of the IP header itself.
+.IP
+ ... \fB0 >> 22 & 0x3C @ 0 >> 24 = 0\fR"
+.IP
+The first 0 means read bytes 0-3, \fB>>22\fR means shift that 22 bits to the
+right. Shifting 24 bits would give the first byte, so only 22 bits is four
+times that plus a few more bits. \fB&3C\fR then eliminates the two extra bits
+on the right and the first four bits of the first byte. For instance, if IHL=5,
+then the IP header is 20 (4 x 5) bytes long. In this case, bytes 0-1 are (in
+binary) xxxx0101 yyzzzzzz, \fB>>22\fR gives the 10 bit value xxxx0101yy and
+\fB&3C\fR gives 010100. \fB@\fR means to use this number as a new offset into
+the packet, and read four bytes starting from there. This is the first 4 bytes
+of the ICMP payload, of which byte 0 is the ICMP type. Therefore, we simply
+shift the value 24 to the right to throw out all but the first byte and compare
+the result with 0.
+.PP
+Example:
+.IP
+TCP payload bytes 8-12 is any of 1, 2, 5 or 8
+.IP
+First we test that the packet is a tcp packet (similar to ICMP).
+.IP
+\-\-u32 "\fB6 & 0xFF = 6 &&\fP ...
+.IP
+Next, test that it is not a fragment (same as above).
+.IP
+ ... \fB0 >> 22 & 0x3C @ 12 >> 26 & 0x3C @ 8 = 1,2,5,8\fR"
+.IP
+\fB0>>22&3C\fR as above computes the number of bytes in the IP header. \fB@\fR
+makes this the new offset into the packet, which is the start of the TCP
+header. The length of the TCP header (again in 32 bit words) is the left half
+of byte 12 of the TCP header. The \fB12>>26&3C\fR computes this length in bytes
+(similar to the IP header before). "@" makes this the new offset, which is the
+start of the TCP payload. Finally, 8 reads bytes 8-12 of the payload and
+\fB=\fR checks whether the result is any of 1, 2, 5 or 8.

+.SH DESCRIPTION
+\fBIp6tables\fP is used to set up, maintain, and inspect the
+tables of IPv6 packet
+filter rules in the Linux kernel. Several different tables
+may be defined. Each table contains a number of built-in
+chains and may also contain user-defined chains.
+.PP
+Each chain is a list of rules which can match a set of packets. Each
+rule specifies what to do with a packet that matches. This is called
+a `target', which may be a jump to a user-defined chain in the same
+table.
+.SH TARGETS
+A firewall rule specifies criteria for a packet and a target. If the
+packet does not match, the next rule in the chain is the examined; if
+it does match, then the next rule is specified by the value of the
+target, which can be the name of a user-defined chain or one of the
+special values \fBACCEPT\fP, \fBDROP\fP, \fBQUEUE\fP or \fBRETURN\fP.
+.PP
+\fBACCEPT\fP means to let the packet through.
+\fBDROP\fP means to drop the packet on the floor.
+\fBQUEUE\fP means to pass the packet to userspace.
+(How the packet can be received
+by a userspace process differs by the particular queue handler. 2.4.x
+and 2.6.x kernels up to 2.6.13 include the \fBip_queue\fP
+queue handler. Kernels 2.6.14 and later additionally include the
+\fBnfnetlink_queue\fP queue handler. Packets with a target of QUEUE will be
+sent to queue number '0' in this case. Please also see the \fBNFQUEUE\fP
+target as described later in this man page.)
+\fBRETURN\fP means stop traversing this chain and resume at the next
+rule in the
+previous (calling) chain. If the end of a built-in chain is reached
+or a rule in a built-in chain with target \fBRETURN\fP
+is matched, the target specified by the chain policy determines the
+fate of the packet.
+.SH TABLES
+There are currently three independent tables (which tables are present
+at any time depends on the kernel configuration options and which
+modules are present).
+.TP
+\fB\-t\fP, \fB\-\-table\fP \fItable\fP
+This option specifies the packet matching table which the command
+should operate on. If the kernel is configured with automatic module
+loading, an attempt will be made to load the appropriate module for
+that table if it is not already there.
+
+The tables are as follows:
+.RS
+.TP .4i
+\fBfilter\fP:
+This is the default table (if no \-t option is passed). It contains
+the built-in chains \fBINPUT\fP (for packets destined to local sockets),
+\fBFORWARD\fP (for packets being routed through the box), and
+\fBOUTPUT\fP (for locally-generated packets).
+.TP
+\fBmangle\fP:
+This table is used for specialized packet alteration. Until kernel
+2.4.17 it had two built-in chains: \fBPREROUTING\fP
+(for altering incoming packets before routing) and \fBOUTPUT\fP
+(for altering locally-generated packets before routing).
+Since kernel 2.4.18, three other built-in chains are also supported:
+\fBINPUT\fP (for packets coming into the box itself), \fBFORWARD\fP
+(for altering packets being routed through the box), and \fBPOSTROUTING\fP
+(for altering packets as they are about to go out).
+.TP
+\fBraw\fP:
+This table is used mainly for configuring exemptions from connection
+tracking in combination with the NOTRACK target. It registers at the netfilter
+hooks with higher priority and is thus called before ip_conntrack, or any other
+IP tables. It provides the following built-in chains: \fBPREROUTING\fP
+(for packets arriving via any network interface) \fBOUTPUT\fP
+(for packets generated by local processes)
+.RE
+.SH OPTIONS
+The options that are recognized by
+\fBip6tables\fP can be divided into several different groups.
+.SS COMMANDS
+These options specify the specific action to perform. Only one of them
+can be specified on the command line unless otherwise specified
+below. For all the long versions of the command and option names, you
+need to use only enough letters to ensure that
+\fBip6tables\fP can differentiate it from all other options.
+.TP
+\fB\-A\fP, \fB\-\-append\fP \fIchain rule-specification\fP
+Append one or more rules to the end of the selected chain.
+When the source and/or destination names resolve to more than one
+address, a rule will be added for each possible address combination.
+.TP
+\fB\-D\fP, \fB\-\-delete\fP \fIchain rule-specification\fP
+.ns
+.TP
+\fB\-D\fP, \fB\-\-delete\fP \fIchain rulenum\fP
+Delete one or more rules from the selected chain. There are two
+versions of this command: the rule can be specified as a number in the
+chain (starting at 1 for the first rule) or a rule to match.
+.TP
+\fB\-I\fP, \fB\-\-insert\fP \fIchain\fP [\fIrulenum\fP] \fIrule-specification\fP
+Insert one or more rules in the selected chain as the given rule
+number. So, if the rule number is 1, the rule or rules are inserted
+at the head of the chain. This is also the default if no rule number
+is specified.
+.TP
+\fB\-R\fP, \fB\-\-replace\fP \fIchain rulenum rule-specification\fP
+Replace a rule in the selected chain. If the source and/or
+destination names resolve to multiple addresses, the command will
+fail. Rules are numbered starting at 1.
+.TP
+\fB\-L\fP, \fB\-\-list\fP [\fIchain\fP]
+List all rules in the selected chain. If no chain is selected, all
+chains are listed. Like every other ip6tables command, it applies to the
+specified table (filter is the default).
+.IP ""
+Please note that it is often used with the \fB\-n\fP
+option, in order to avoid long reverse DNS lookups.
+It is legal to specify the \fB\-Z\fP
+(zero) option as well, in which case the chain(s) will be atomically
+listed and zeroed. The exact output is affected by the other
+arguments given. The exact rules are suppressed until you use
+.nf
+ ip6tables \-L \-v
+.fi
+.TP
+\fB\-S\fP, \fB\-\-list\-rules\fP [\fIchain\fP]
+Print all rules in the selected chain. If no chain is selected, all
+chains are printed like ip6tables-save. Like every other ip6tables command,
+it applies to the specified table (filter is the default).
+.TP
+\fB\-F\fP, \fB\-\-flush\fP [\fIchain\fP]
+Flush the selected chain (all the chains in the table if none is given).
+This is equivalent to deleting all the rules one by one.
+.TP
+\fB\-Z\fP, \fB\-\-zero\fP [\fIchain\fP [\fIrulenum\fP]]
+Zero the packet and byte counters in all chains, or only the given chain,
+or only the given rule in a chain. It is legal to
+specify the
+\fB\-L\fP, \fB\-\-list\fP
+(list) option as well, to see the counters immediately before they are
+cleared. (See above.)
+.TP
+\fB\-N\fP, \fB\-\-new\-chain\fP \fIchain\fP
+Create a new user-defined chain by the given name. There must be no
+target of that name already.
+.TP
+\fB\-X\fP, \fB\-\-delete\-chain\fP [\fIchain\fP]
+Delete the optional user-defined chain specified. There must be no references
+to the chain. If there are, you must delete or replace the referring rules
+before the chain can be deleted. The chain must be empty, i.e. not contain
+any rules. If no argument is given, it will attempt to delete every
+non-builtin chain in the table.
+.TP
+\fB\-P\fP, \fB\-\-policy\fP \fIchain target\fP
+Set the policy for the chain to the given target. See the section \fBTARGETS\fP
+for the legal targets. Only built-in (non-user-defined) chains can have
+policies, and neither built-in nor user-defined chains can be policy
+targets.
+.TP
+\fB\-E\fP, \fB\-\-rename\-chain\fP \fIold\-chain new\-chain\fP
+Rename the user specified chain to the user supplied name. This is
+cosmetic, and has no effect on the structure of the table.
+.TP
+\fB\-A\fP, \fB\-\-append\fP \fIchain rule-specification\fP
+Append one or more rules to the end of the selected chain.
+When the source and/or destination names resolve to more than one
+address, a rule will be added for each possible address combination.
+.TP
+\fB\-h\fP
+Help.
+Give a (currently very brief) description of the command syntax.
+.SS PARAMETERS
+The following parameters make up a rule specification (as used in the
+add, delete, insert, replace and append commands).
+.TP
+[\fB!\fP] \fB\-p\fP, \fB\-\-protocol\fP \fIprotocol\fP
+The protocol of the rule or of the packet to check.
+The specified protocol can be one of \fBtcp\fP, \fBudp\fP, \fBudplite\fP,
+\fBicmpv6\fP, \fBesp\fP, \fBmh\fP or \fBall\fP,
+or it can be a numeric value, representing one of these protocols or a
+different one. A protocol name from /etc/protocols is also allowed.
+But IPv6 extension headers except \fBesp\fP are not allowed.
+\fBesp\fP and \fBipv6\-nonext\fP
+can be used with Kernel version 2.6.11 or later.
+A "!" argument before the protocol inverts the
+test. The number zero is equivalent to \fBall\fP.
+Protocol \fBall\fP
+will match with all protocols and is taken as default when this
+option is omitted.
+.TP
+[\fB!\fP] \fB\-s\fP, \fB\-\-source\fP \fIaddress\fP[\fB/\fP\fImask\fP]
+Source specification.
+\fIAddress\fP can be either be a hostname,
+a network IP address (with \fB/\fP\fImask\fP), or a plain IP address.
+Names will be resolved once only, before the rule is submitted to the kernel.
+Please note that specifying any name to be resolved with a remote query such as
+DNS is a really bad idea.
+(Resolving network names is not supported at this time.)
+The \fImask\fP is a plain number,
+specifying the number of 1's at the left side of the network mask.
+A "!" argument before the address specification inverts the sense of
+the address. The flag \fB\-\-src\fP
+is an alias for this option.
+Multiple addresses can be specified, but this will \fBexpand to multiple
+rules\fP (when adding with \-A), or will cause multiple rules to be
+deleted (with \-D).
+.TP
+[\fB!\fP] \fB\-d\fP, \fB\-\-destination\fP \fIaddress\fP[\fB/\fP\fImask\fP]
+Destination specification.
+See the description of the \fB\-s\fP
+(source) flag for a detailed description of the syntax. The flag
+\fB\-\-dst\fP is an alias for this option.
+.TP
+\fB\-j\fP, \fB\-\-jump\fP \fItarget\fP
+This specifies the target of the rule; i.e., what to do if the packet
+matches it. The target can be a user-defined chain (other than the
+one this rule is in), one of the special builtin targets which decide
+the fate of the packet immediately, or an extension (see \fBEXTENSIONS\fP
+below). If this
+option is omitted in a rule (and \fB\-g\fP
+is not used), then matching the rule will have no
+effect on the packet's fate, but the counters on the rule will be
+incremented.
+.TP
+\fB\-g\fP, \fB\-\-goto\fP \fIchain\fP
+This specifies that the processing should continue in a user
+specified chain. Unlike the \-\-jump option return will not continue
+processing in this chain but instead in the chain that called us via
+\-\-jump.
+.TP
+[\fB!\fP] \fB\-i\fP, \fB\-\-in\-interface\fP \fIname\fP
+Name of an interface via which a packet was received (only for
+packets entering the \fBINPUT\fP, \fBFORWARD\fP and \fBPREROUTING\fP
+chains). When the "!" argument is used before the interface name, the
+sense is inverted. If the interface name ends in a "+", then any
+interface which begins with this name will match. If this option is
+omitted, any interface name will match.
+.TP
+[\fB!\fP] \fB\-o\fP, \fB\-\-out\-interface\fP \fIname\fP
+Name of an interface via which a packet is going to be sent (for packets
+entering the \fBFORWARD\fP, \fBOUTPUT\fP and \fBPOSTROUTING\fP
+chains). When the "!" argument is used before the interface name, the
+sense is inverted. If the interface name ends in a "+", then any
+interface which begins with this name will match. If this option is
+omitted, any interface name will match.
+.\" Currently not supported (header-based)
+.\" .TP
+.\" [\fB!\fP] \fB\-f\fP, \fB\-\-fragment\fP
+.\" This means that the rule only refers to second and further fragments
+.\" of fragmented packets. Since there is no way to tell the source or
+.\" destination ports of such a packet (or ICMP type), such a packet will
+.\" not match any rules which specify them. When the "!" argument
+.\" precedes the "\-f" flag, the rule will only match head fragments, or
+.\" unfragmented packets.
+.TP
+\fB\-c\fP, \fB\-\-set\-counters\fP \fIpackets bytes\fP
+This enables the administrator to initialize the packet and byte
+counters of a rule (during \fBINSERT\fP, \fBAPPEND\fP, \fBREPLACE\fP
+operations).
+.SS "OTHER OPTIONS"
+The following additional options can be specified:
+.TP
+\fB\-v\fP, \fB\-\-verbose\fP
+Verbose output. This option makes the list command show the interface
+name, the rule options (if any), and the TOS masks. The packet and
+byte counters are also listed, with the suffix 'K', 'M' or 'G' for
+1000, 1,000,000 and 1,000,000,000 multipliers respectively (but see
+the \fB\-x\fP flag to change this).
+For appending, insertion, deletion and replacement, this causes
+detailed information on the rule or rules to be printed.
+.TP
+\fB\-n\fP, \fB\-\-numeric\fP
+Numeric output.
+IP addresses and port numbers will be printed in numeric format.
+By default, the program will try to display them as host names,
+network names, or services (whenever applicable).
+.TP
+\fB\-x\fP, \fB\-\-exact\fP
+Expand numbers.
+Display the exact value of the packet and byte counters,
+instead of only the rounded number in K's (multiples of 1000)
+M's (multiples of 1000K) or G's (multiples of 1000M). This option is
+only relevant for the \fB\-L\fP command.
+.TP
+\fB\-\-line\-numbers\fP
+When listing rules, add line numbers to the beginning of each rule,
+corresponding to that rule's position in the chain.
+.TP
+\fB\-\-modprobe=\fP\fIcommand\fP
+When adding or inserting rules into a chain, use \fIcommand\fP
+to load any necessary modules (targets, match extensions, etc).
+.SH MATCH EXTENSIONS
+ip6tables can use extended packet matching modules. These are loaded
+in two ways: implicitly, when \fB\-p\fP or \fB\-\-protocol\fP
+is specified, or with the \fB\-m\fP or \fB\-\-match\fP
+options, followed by the matching module name; after these, various
+extra command line options become available, depending on the specific
+module. You can specify multiple extended match modules in one line,
+and you can use the \fB\-h\fP or \fB\-\-help\fP
+options after the module has been specified to receive help specific
+to that module.
+.PP
+The following are included in the base package, and most of these can
+be preceded by a "\fB!\fP" to invert the sense of the match.
+.\" @MATCH@
+.SH TARGET EXTENSIONS
+ip6tables can use extended target modules: the following are included
+in the standard distribution.
+.\" @TARGET@
+.SH DIAGNOSTICS
+Various error messages are printed to standard error. The exit code
+is 0 for correct functioning. Errors which appear to be caused by
+invalid or abused command line parameters cause an exit code of 2, and
+other errors cause an exit code of 1.
+.SH BUGS
+Bugs? What's this? ;-)
+Well... the counters are not reliable on sparc64.
+.SH COMPATIBILITY WITH IPCHAINS
+This \fBip6tables\fP
+is very similar to ipchains by Rusty Russell. The main difference is
+that the chains \fBINPUT\fP and \fBOUTPUT\fP
+are only traversed for packets coming into the local host and
+originating from the local host respectively. Hence every packet only
+passes through one of the three chains (except loopback traffic, which
+involves both INPUT and OUTPUT chains); previously a forwarded packet
+would pass through all three.
+.PP
+The other main difference is that \fB\-i\fP refers to the input interface;
+\fB\-o\fP refers to the output interface, and both are available for packets
+entering the \fBFORWARD\fP chain.
+There are several other changes in ip6tables.

+.SH NAME
+iptables-xml \(em Convert iptables-save format to XML
+.SH SYNOPSIS
+\fBiptables\-xml\fP [\fB\-c\fP] [\fB\-v\fP]
+.SH DESCRIPTION
+.PP
+.B iptables-xml
+is used to convert the output of iptables-save into an easily manipulatable
+XML format to STDOUT. Use I/O-redirection provided by your shell to write to
+a file.
+.TP
+\fB\-c\fR, \fB\-\-combine\fR
+combine consecutive rules with the same matches but different targets. iptables
+does not currently support more than one target per match, so this simulates
+that by collecting the targets from consecutive iptables rules into one action
+tag, but only when the rule matches are identical. Terminating actions like
+RETURN, DROP, ACCEPT and QUEUE are not combined with subsequent targets.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Output xml comments containing the iptables line from which the XML is derived
+
+.PP
+iptables-xml does a mechanistic conversion to a very expressive xml
+format; the only semantic considerations are for \-g and \-j targets in
+order to discriminate between <call> <goto> and <nane-of-target> as it
+helps xml processing scripts if they can tell the difference between a
+target like SNAT and another chain.
+
+Some sample output is:
+
+<iptables-rules>
+ <table name="mangle">
+ <chain name="PREROUTING" policy="ACCEPT" packet-count="63436"
+byte-count="7137573">
+ <rule>
+ <conditions>
+ <match>
+ <p>tcp</p>
+ </match>
+ <tcp>
+ <sport>8443</sport>
+ </tcp>
+ </conditions>
+ <actions>
+ <call>
+ <check_ip/>
+ </call>
+ <ACCEPT/>
+ </actions>
+ </rule>
+ </chain>
+ </table>
+</iptables-rules>
+
+.PP
+Conversion from XML to iptables-save format may be done using the
+iptables.xslt script and xsltproc, or a custom program using
+libxsltproc or similar; in this fashion:
+
+xsltproc iptables.xslt my-iptables.xml | iptables-restore

+.SH DESCRIPTION
+\fBIptables\fP is used to set up, maintain, and inspect the
+tables of IPv4 packet
+filter rules in the Linux kernel. Several different tables
+may be defined. Each table contains a number of built-in
+chains and may also contain user-defined chains.
+.PP
+Each chain is a list of rules which can match a set of packets. Each
+rule specifies what to do with a packet that matches. This is called
+a `target', which may be a jump to a user-defined chain in the same
+table.
+.SH TARGETS
+A firewall rule specifies criteria for a packet and a target. If the
+packet does not match, the next rule in the chain is the examined; if
+it does match, then the next rule is specified by the value of the
+target, which can be the name of a user-defined chain or one of the
+special values \fBACCEPT\fP, \fBDROP\fP, \fBQUEUE\fP or \fBRETURN\fP.
+.PP
+\fBACCEPT\fP means to let the packet through.
+\fBDROP\fP means to drop the packet on the floor.
+\fBQUEUE\fP means to pass the packet to userspace.
+(How the packet can be received
+by a userspace process differs by the particular queue handler. 2.4.x
+and 2.6.x kernels up to 2.6.13 include the \fBip_queue\fP
+queue handler. Kernels 2.6.14 and later additionally include the
+\fBnfnetlink_queue\fP queue handler. Packets with a target of QUEUE will be
+sent to queue number '0' in this case. Please also see the \fBNFQUEUE\fP
+target as described later in this man page.)
+\fBRETURN\fP means stop traversing this chain and resume at the next
+rule in the
+previous (calling) chain. If the end of a built-in chain is reached
+or a rule in a built-in chain with target \fBRETURN\fP
+is matched, the target specified by the chain policy determines the
+fate of the packet.
+.SH TABLES
+There are currently three independent tables (which tables are present
+at any time depends on the kernel configuration options and which
+modules are present).
+.TP
+\fB\-t\fP, \fB\-\-table\fP \fItable\fP
+This option specifies the packet matching table which the command
+should operate on. If the kernel is configured with automatic module
+loading, an attempt will be made to load the appropriate module for
+that table if it is not already there.
+
+The tables are as follows:
+.RS
+.TP .4i
+\fBfilter\fP:
+This is the default table (if no \-t option is passed). It contains
+the built-in chains \fBINPUT\fP (for packets destined to local sockets),
+\fBFORWARD\fP (for packets being routed through the box), and
+\fBOUTPUT\fP (for locally-generated packets).
+.TP
+\fBnat\fP:
+This table is consulted when a packet that creates a new
+connection is encountered. It consists of three built-ins: \fBPREROUTING\fP
+(for altering packets as soon as they come in), \fBOUTPUT\fP
+(for altering locally-generated packets before routing), and \fBPOSTROUTING\fP
+(for altering packets as they are about to go out).
+.TP
+\fBmangle\fP:
+This table is used for specialized packet alteration. Until kernel
+2.4.17 it had two built-in chains: \fBPREROUTING\fP
+(for altering incoming packets before routing) and \fBOUTPUT\fP
+(for altering locally-generated packets before routing).
+Since kernel 2.4.18, three other built-in chains are also supported:
+\fBINPUT\fP (for packets coming into the box itself), \fBFORWARD\fP
+(for altering packets being routed through the box), and \fBPOSTROUTING\fP
+(for altering packets as they are about to go out).
+.TP
+\fBraw\fP:
+This table is used mainly for configuring exemptions from connection
+tracking in combination with the NOTRACK target. It registers at the netfilter
+hooks with higher priority and is thus called before ip_conntrack, or any other
+IP tables. It provides the following built-in chains: \fBPREROUTING\fP
+(for packets arriving via any network interface) \fBOUTPUT\fP
+(for packets generated by local processes)
+.RE
+.SH OPTIONS
+The options that are recognized by
+\fBiptables\fP can be divided into several different groups.
+.SS COMMANDS
+These options specify the desired action to perform. Only one of them
+can be specified on the command line unless otherwise stated
+below. For long versions of the command and option names, you
+need to use only enough letters to ensure that
+\fBiptables\fP can differentiate it from all other options.
+.TP
+\fB\-A\fP, \fB\-\-append\fP \fIchain rule-specification\fP
+Append one or more rules to the end of the selected chain.
+When the source and/or destination names resolve to more than one
+address, a rule will be added for each possible address combination.
+.TP
+\fB\-D\fP, \fB\-\-delete\fP \fIchain rule-specification\fP
+.ns
+.TP
+\fB\-D\fP, \fB\-\-delete\fP \fIchain rulenum\fP
+Delete one or more rules from the selected chain. There are two
+versions of this command: the rule can be specified as a number in the
+chain (starting at 1 for the first rule) or a rule to match.
+.TP
+\fB\-I\fP, \fB\-\-insert\fP \fIchain\fP [\fIrulenum\fP] \fIrule-specification\fP
+Insert one or more rules in the selected chain as the given rule
+number. So, if the rule number is 1, the rule or rules are inserted
+at the head of the chain. This is also the default if no rule number
+is specified.
+.TP
+\fB\-R\fP, \fB\-\-replace\fP \fIchain rulenum rule-specification\fP
+Replace a rule in the selected chain. If the source and/or
+destination names resolve to multiple addresses, the command will
+fail. Rules are numbered starting at 1.
+.TP
+\fB\-L\fP, \fB\-\-list\fP [\fIchain\fP]
+List all rules in the selected chain. If no chain is selected, all
+chains are listed. Like every other iptables command, it applies to the
+specified table (filter is the default), so NAT rules get listed by
+.nf
+ iptables \-t nat \-n \-L
+.fi
+Please note that it is often used with the \fB\-n\fP
+option, in order to avoid long reverse DNS lookups.
+It is legal to specify the \fB\-Z\fP
+(zero) option as well, in which case the chain(s) will be atomically
+listed and zeroed. The exact output is affected by the other
+arguments given. The exact rules are suppressed until you use
+.nf
+ iptables \-L \-v
+.fi
+.TP
+\fB\-S\fP, \fB\-\-list\-rules\fP [\fIchain\fP]
+Print all rules in the selected chain. If no chain is selected, all
+chains are printed like iptables-save. Like every other iptables command,
+it applies to the specified table (filter is the default).
+.TP
+\fB\-F\fP, \fB\-\-flush\fP [\fIchain\fP]
+Flush the selected chain (all the chains in the table if none is given).
+This is equivalent to deleting all the rules one by one.
+.TP
+\fB\-Z\fP, \fB\-\-zero\fP [\fIchain\fP [\fIrulenum\fP]]
+Zero the packet and byte counters in all chains, or only the given chain,
+or only the given rule in a chain. It is legal to
+specify the
+\fB\-L\fP, \fB\-\-list\fP
+(list) option as well, to see the counters immediately before they are
+cleared. (See above.)
+.TP
+\fB\-N\fP, \fB\-\-new\-chain\fP \fIchain\fP
+Create a new user-defined chain by the given name. There must be no
+target of that name already.
+.TP
+\fB\-X\fP, \fB\-\-delete\-chain\fP [\fIchain\fP]
+Delete the optional user-defined chain specified. There must be no references
+to the chain. If there are, you must delete or replace the referring rules
+before the chain can be deleted. The chain must be empty, i.e. not contain
+any rules. If no argument is given, it will attempt to delete every
+non-builtin chain in the table.
+.TP
+\fB\-P\fP, \fB\-\-policy\fP \fIchain target\fP
+Set the policy for the chain to the given target. See the section \fBTARGETS\fP
+for the legal targets. Only built-in (non-user-defined) chains can have
+policies, and neither built-in nor user-defined chains can be policy
+targets.
+.TP
+\fB\-E\fP, \fB\-\-rename\-chain\fP \fIold\-chain new\-chain\fP
+Rename the user specified chain to the user supplied name. This is
+cosmetic, and has no effect on the structure of the table.
+.TP
+\fB\-h\fP
+Help.
+Give a (currently very brief) description of the command syntax.
+.SS PARAMETERS
+The following parameters make up a rule specification (as used in the
+add, delete, insert, replace and append commands).
+.TP
+[\fB!\fP] \fB\-p\fP, \fB\-\-protocol\fP \fIprotocol\fP
+The protocol of the rule or of the packet to check.
+The specified protocol can be one of \fBtcp\fP, \fBudp\fP, \fBudplite\fP,
+\fBicmp\fP, \fBesp\fP, \fBah\fP, \fBsctp\fP or \fBall\fP,
+or it can be a numeric value, representing one of these protocols or a
+different one. A protocol name from /etc/protocols is also allowed.
+A "!" argument before the protocol inverts the
+test. The number zero is equivalent to \fBall\fP.
+Protocol \fBall\fP
+will match with all protocols and is taken as default when this
+option is omitted.
+.TP
+[\fB!\fP] \fB\-s\fP, \fB\-\-source\fP \fIaddress\fP[\fB/\fP\fImask\fP][\fB,\fP\fI...\fP]
+Source specification. \fIAddress\fP
+can be either a network name, a hostname, a network IP address (with
+\fB/\fP\fImask\fP), or a plain IP address. Hostnames will
+be resolved once only, before the rule is submitted to the kernel.
+Please note that specifying any name to be resolved with a remote query such as
+DNS is a really bad idea.
+The \fImask\fP
+can be either a network mask or a plain number,
+specifying the number of 1's at the left side of the network mask.
+Thus, a mask of \fI24\fP is equivalent to \fI255.255.255.0\fP.
+A "!" argument before the address specification inverts the sense of
+the address. The flag \fB\-\-src\fP is an alias for this option.
+Multiple addresses can be specified, but this will \fBexpand to multiple
+rules\fP (when adding with \-A), or will cause multiple rules to be
+deleted (with \-D).
+.TP
+[\fB!\fP] \fB\-d\fP, \fB\-\-destination\fP \fIaddress\fP[\fB/\fP\fImask\fP][\fB,\fP\fI...\fP]
+Destination specification.
+See the description of the \fB\-s\fP
+(source) flag for a detailed description of the syntax. The flag
+\fB\-\-dst\fP is an alias for this option.
+.TP
+\fB\-j\fP, \fB\-\-jump\fP \fItarget\fP
+This specifies the target of the rule; i.e., what to do if the packet
+matches it. The target can be a user-defined chain (other than the
+one this rule is in), one of the special builtin targets which decide
+the fate of the packet immediately, or an extension (see \fBEXTENSIONS\fP
+below). If this
+option is omitted in a rule (and \fB\-g\fP
+is not used), then matching the rule will have no
+effect on the packet's fate, but the counters on the rule will be
+incremented.
+.TP
+\fB\-g\fP, \fB\-\-goto\fP \fIchain\fP
+This specifies that the processing should continue in a user
+specified chain. Unlike the \-\-jump option return will not continue
+processing in this chain but instead in the chain that called us via
+\-\-jump.
+.TP
+[\fB!\fP] \fB\-i\fP, \fB\-\-in\-interface\fP \fIname\fP
+Name of an interface via which a packet was received (only for
+packets entering the \fBINPUT\fP, \fBFORWARD\fP and \fBPREROUTING\fP
+chains). When the "!" argument is used before the interface name, the
+sense is inverted. If the interface name ends in a "+", then any
+interface which begins with this name will match. If this option is
+omitted, any interface name will match.
+.TP
+[\fB!\fP] \fB\-o\fP, \fB\-\-out\-interface\fP \fIname\fP
+Name of an interface via which a packet is going to be sent (for packets
+entering the \fBFORWARD\fP, \fBOUTPUT\fP and \fBPOSTROUTING\fP
+chains). When the "!" argument is used before the interface name, the
+sense is inverted. If the interface name ends in a "+", then any
+interface which begins with this name will match. If this option is
+omitted, any interface name will match.
+.TP
+[\fB!\fP] \fB\-f\fP, \fB\-\-fragment\fP
+This means that the rule only refers to second and further fragments
+of fragmented packets. Since there is no way to tell the source or
+destination ports of such a packet (or ICMP type), such a packet will
+not match any rules which specify them. When the "!" argument
+precedes the "\-f" flag, the rule will only match head fragments, or
+unfragmented packets.
+.TP
+\fB\-c\fP, \fB\-\-set\-counters\fP \fIpackets bytes\fP
+This enables the administrator to initialize the packet and byte
+counters of a rule (during \fBINSERT\fP, \fBAPPEND\fP, \fBREPLACE\fP
+operations).
+.SS "OTHER OPTIONS"
+The following additional options can be specified:
+.TP
+\fB\-v\fP, \fB\-\-verbose\fP
+Verbose output. This option makes the list command show the interface
+name, the rule options (if any), and the TOS masks. The packet and
+byte counters are also listed, with the suffix 'K', 'M' or 'G' for
+1000, 1,000,000 and 1,000,000,000 multipliers respectively (but see
+the \fB\-x\fP flag to change this).
+For appending, insertion, deletion and replacement, this causes
+detailed information on the rule or rules to be printed.
+.TP
+\fB\-n\fP, \fB\-\-numeric\fP
+Numeric output.
+IP addresses and port numbers will be printed in numeric format.
+By default, the program will try to display them as host names,
+network names, or services (whenever applicable).
+.TP
+\fB\-x\fP, \fB\-\-exact\fP
+Expand numbers.
+Display the exact value of the packet and byte counters,
+instead of only the rounded number in K's (multiples of 1000)
+M's (multiples of 1000K) or G's (multiples of 1000M). This option is
+only relevant for the \fB\-L\fP command.
+.TP
+\fB\-\-line\-numbers\fP
+When listing rules, add line numbers to the beginning of each rule,
+corresponding to that rule's position in the chain.
+.TP
+\fB\-\-modprobe=\fP\fIcommand\fP
+When adding or inserting rules into a chain, use \fIcommand\fP
+to load any necessary modules (targets, match extensions, etc).
+.SH MATCH EXTENSIONS
+iptables can use extended packet matching modules. These are loaded
+in two ways: implicitly, when \fB\-p\fP or \fB\-\-protocol\fP
+is specified, or with the \fB\-m\fP or \fB\-\-match\fP
+options, followed by the matching module name; after these, various
+extra command line options become available, depending on the specific
+module. You can specify multiple extended match modules in one line,
+and you can use the \fB\-h\fP or \fB\-\-help\fP
+options after the module has been specified to receive help specific
+to that module.
+.PP
+The following are included in the base package, and most of these can
+be preceded by a "\fB!\fP" to invert the sense of the match.
+.\" @MATCH@
+.SH TARGET EXTENSIONS
+iptables can use extended target modules: the following are included
+in the standard distribution.
+.\" @TARGET@
+.SH DIAGNOSTICS
+Various error messages are printed to standard error. The exit code
+is 0 for correct functioning. Errors which appear to be caused by
+invalid or abused command line parameters cause an exit code of 2, and
+other errors cause an exit code of 1.
+.SH BUGS
+Bugs? What's this? ;-)
+Well, you might want to have a look at http://bugzilla.netfilter.org/
+.SH COMPATIBILITY WITH IPCHAINS
+This \fBiptables\fP
+is very similar to ipchains by Rusty Russell. The main difference is
+that the chains \fBINPUT\fP and \fBOUTPUT\fP
+are only traversed for packets coming into the local host and
+originating from the local host respectively. Hence every packet only
+passes through one of the three chains (except loopback traffic, which
+involves both INPUT and OUTPUT chains); previously a forwarded packet
+would pass through all three.
+.PP
+The other main difference is that \fB\-i\fP refers to the input interface;
+\fB\-o\fP refers to the output interface, and both are available for packets
+entering the \fBFORWARD\fP chain.
+.PP
+The various forms of NAT have been separated out; \fBiptables\fP
+is a pure packet filter when using the default `filter' table, with
+optional extension modules. This should simplify much of the previous
+confusion over the combination of IP masquerading and packet filtering
+seen previously. So the following options are handled differently:
+.nf
+ \-j MASQ
+ \-M \-S
+ \-M \-L
+.fi
+There are several other changes in iptables.

+ipq_create_handle, ipq_destroy_handle \(em create and destroy libipq handles.
+.SH SYNOPSIS
+.B #include <linux/netfilter.h>
+.br
+.B #include <libipq.h>
+.sp
+.BI "struct ipq_handle *ipq_create_handle(u_int32_t " flags ", u_int32_t " protocol ");"
+.br
+.BI "int ipq_destroy_handle(struct ipq_handle *" h );
+.SH DESCRIPTION
+The
+.B ipq_create_handle
+function initialises libipq for an application, attempts to bind to the
+Netlink socket used by ip_queue, and returns an opaque context handle. It
+should be the first libipq function to be called by an application. The
+handle returned should be used in all subsequent library calls which
+require a handle parameter.
+.PP
+The
+.I flags
+parameter is not currently used and should be set to zero by the application
+for forward compatibility.
+.PP
+The
+.I protocol
+parameter is used to specify the protocol of the packets to be queued.
+Valid values are NFPROTO_IPV4 for IPv4 and NFPROTO_IPV6 for IPv6. Currently,
+only one protocol may be queued at a time for a handle.
+.PP
+The
+.B ipq_destroy_handle
+function frees up resources allocated by
+.BR ipq_create_handle ,
+and should be used when the handle is no longer required by the application.
+.SH RETURN VALUES
+On success,
+.B ipq_create_handle
+returns a pointer to a context handle.
+.br
+On failure, NULL is returned.
+.PP
+On success,
+.B ipq_destroy_handle
+returns zero.
+.br
+On failure, \-1 is returned.
+.SH ERRORS
+On failure, a descriptive error message will be available
+via the
+.B ipq_errstr
+function.
+.SH BUGS
+None known.

+.BI "char *ipq_errstr(" void );
+.br
+.BI "void ipq_perror(const char *" s );
+.SH DESCRIPTION
+The
+.B ipq_errstr
+function returns a descriptive error message based on the current
+value of the internal
+.B ipq_errno
+variable. All libipq API functions set this internal variable
+upon failure.
+.PP
+The
+.B ipq_perror
+function prints an error message to stderr corresponding to the
+current value of the internal
+.B ipq_error
+variable, and the global
+.B errno
+variable (if set). The error message is prefixed with the string
+.I s
+as supplied by the application. If
+.I s
+is NULL, the error message is prefixed with the string "ERROR".
+.SH RETURN VALUE
+.B ipq_errstr
+returns an error message as outlined above.

+.BI "int ipq_message_type(const unsigned char *" buf ");"
+.br
+.BI "ipq_packet_msg_t *ipq_get_packet(const unsigned char *" buf ");"
+.br
+.BI "int ipq_get_msgerr(const unsigned char *" buf ");"
+.SH DESCRIPTION
+The
+.B ipq_message_type
+function returns the type of queue message returned to userspace
+via
+.BR ipq_read .
+.PP
+.B ipq_message_type
+should always be called following a successful call to
+.B ipq_read
+to determine whether the message is a packet message or an
+error message. The
+.I buf
+parameter should be the same data obtained from
+the previous call to
+.BR ipq_read .
+.PP
+.B ipq_message_type
+will return one of the following values:
+.TP
+.B NLMSG_ERROR
+An error message generated by the Netlink transport.
+.PP
+.TP
+.B IPQM_PACKET
+A packet message containing packet metadata and optional packet payload data.
+.PP
+The
+.B ipq_get_packet
+function should be called if
+.B ipq_message_type
+returns
+.BR IPQM_PACKET .
+The
+.I buf
+parameter should point to the same data used for the call to
+.BR ipq_message_type .
+The pointer returned by
+.B ipq_get_packet
+points to a packet message, which is declared as follows:
+.PP
+.RS
+.nf
+typedef struct ipq_packet_msg {
+ unsigned long packet_id; /* ID of queued packet */
+ unsigned long mark; /* Netfilter mark value */
+ long timestamp_sec; /* Packet arrival time (seconds) */
+ long timestamp_usec; /* Packet arrvial time (+useconds) */
+ unsigned int hook; /* Netfilter hook we rode in on */
+ char indev_name[IFNAMSIZ]; /* Name of incoming interface */
+ char outdev_name[IFNAMSIZ]; /* Name of outgoing interface */
+ unsigned short hw_protocol; /* Hardware protocol (network order) */
+ unsigned short hw_type; /* Hardware type */
+ unsigned char hw_addrlen; /* Hardware address length */
+ unsigned char hw_addr[8]; /* Hardware address */
+ size_t data_len; /* Length of packet data */
+ unsigned char payload[0]; /* Optional packet data */
+} ipq_packet_msg_t;
+.fi
+.RE
+.PP
+Each of these fields may be read by the application. If the queue mode
+is
+.B IPQ_COPY_PACKET
+and the
+.I data_len
+value is greater than zero, the packet payload contents may be accessed
+in the memory following the
+.B ipq_packet_msg_t
+structure to a range of
+.I data_len.
+.PP
+The
+.I packet_id
+field contains a packet identifier to be used when calling
+.BR ipq_set_verdict .

+.SH NAME
+ipq_read \(em read queue messages from ip_queue and read into supplied buffer
+.SH SYNOPSIS
+.B #include <linux/netfilter.h>
+.br
+.B #include <libipq.h>
+.sp
+.BI "ssize_t ipq_read(const struct ipq_handle *" h ", unsigned char *" buf ", size_t " len ", int " timeout ");"
+.SH DESCRIPTION
+The
+.B ipq_read
+function reads a queue message from the kernel and copies it to
+the memory pointed to by
+.I buf
+to a maximum length of
+. IR len .
+.PP
+The
+.I h
+parameter is a context handle which must previously have been returned
+successfully from a call to
+.BR ipq_create_handle .
+.PP
+The caller is responsible for ensuring that the memory pointed to by
+.I buf
+is large enough to contain
+.I len
+bytes.
+.PP
+The
+.I timeout
+parameter may be used to set a timeout for the operation, specified in microseconds.
+This is implemented internally by the library via the
+.BR select
+system call. A value of zero provides normal, backwards-compatible blocking behaviour
+with no timeout. A negative value causes the function to return immediately.
+.PP
+Data returned via
+.I buf
+should not be accessed directly. Use the
+.BR ipq_message_type ,
+.BR ipq_get_packet ", and"
+.BR ipq_get_msgerr
+functions to access the queue message in the buffer.
+.SH RETURN VALUE
+On failure, \-1 is returned.
+.br
+On success, a non-zero positive value is returned when no timeout
+value is specified.
+.br
+On success with a timeout value specified, zero is returned if no data
+was available to read, or if a non-blocked signal was caught. In the
+latter case, the global
+.B errno
+value will be set to
+.BR EINTR .
+.SH ERRORS
+On error, a descriptive error message will be available
+via the
+.B ipq_errstr
+function.
+.SH DIAGNOSTICS
+While the
+.B ipq_read
+function may return successfully, the queue message copied to the buffer
+may itself be an error message from a higher level kernel component. Use
+.B ipq_message_type
+to determine if it is an error message, and
+.B ipq_get_msgerr
+to access the value of the message.
+.SH BUGS
+None known.

+.br
+.B #include <libipq.h>
+.sp
+.BI "int ipq_set_mode(const struct ipq_handle *" h ", u_int8_t " mode ", size_t " range );
+.SH DESCRIPTION
+The
+.B ipq_set_mode
+function sends a message to the kernel ip_queue module, specifying whether
+packet metadata only, or packet payloads as well as metadata should be copied to
+userspace.
+.PP
+The
+.I h
+parameter is a context handle which must previously have been returned
+successfully from a call to
+.BR ipq_create_handle .
+.PP
+The
+.I mode
+parameter must be one of:
+.TP
+.B IPQ_COPY_META
+Copy only packet metadata to userspace.
+.TP
+.B IPQ_COPY_PACKET
+Copy packet metadata and packet payloads to userspace.
+.PP
+The
+.I range
+parameter is used to specify how many bytes of the payload to copy
+to userspace. It is only valid for
+.B IPQ_COPY_PACKET
+mode and is otherwise ignored. The maximum useful value for
+.I range
+is 65535 (greater values will be clamped to this by ip_queue).
+.PP
+.B ipq_set_mode
+is usually used immediately following
+.B ipq_create_handle
+to enable the flow of packets to userspace.
+.PP
+Note that as the underlying Netlink messaging transport is connectionless,
+the ip_queue module does not know that a userspace application is ready to
+communicate until it receives a message such as this.
+.SH RETURN VALUE
+On failure, \-1 is returned.
+.br
+On success, a non-zero positive value is returned.
+.SH ERRORS
+On failure, a descriptive error message will be available
+via the
+.B ipq_errstr
+function.
+.SH DIAGNOSTICS
+A relatively common failure may occur if the ip_queue module is not loaded.
+In this case, the following code excerpt:
+.PP
+.RS
+.nf
+status = ipq_set_mode(h, IPQ_COPY_META, 0);
+if (status < 0) {
+ ipq_perror("myapp");
+ ipq_destroy_handle(h);
+ exit(1);
+}
+.RE

+.SH NAME
+libipq \(em iptables userspace packet queuing library.
+.SH SYNOPSIS
+.B #include <linux/netfilter.h>
+.br
+.B #include <libipq.h>
+.SH DESCRIPTION
+libipq is a development library for iptables userspace packet queuing.
+.SS Userspace Packet Queuing
+Netfilter provides a mechanism for passing packets out of the stack for
+queueing to userspace, then receiving these packets back into the kernel
+with a verdict specifying what to do with the packets (such as ACCEPT
+or DROP). These packets may also be modified in userspace prior to
+reinjection back into the kernel.
+.PP
+For each supported protocol, a kernel module called a
+.I queue handler
+may register with Netfilter to perform the mechanics of passing
+packets to and from userspace.
+.PP
+The standard queue handler for IPv4 is ip_queue. It is provided as an
+experimental module with 2.4 kernels, and uses a Netlink socket for
+kernel/userspace communication.
+.PP
+Once ip_queue is loaded, IP packets may be selected with iptables
+and queued for userspace processing via the QUEUE target. For example,
+running the following commands:
+.PP
+ # modprobe iptable_filter
+.br
+ # modprobe ip_queue
+.br
+ # iptables \-A OUTPUT \-p icmp \-j QUEUE
+.PP
+will cause any locally generated ICMP packets (e.g. ping output) to
+be sent to the ip_queue module, which will then attempt to deliver the
+packets to a userspace application. If no userspace application is waiting,
+the packets will be dropped
+.PP
+An application may receive and process these packets via libipq.
+.PP
+.PP
+.SS Libipq Overview
+Libipq provides an API for communicating with ip_queue. The following is
+an overview of API usage, refer to individual man pages for more details
+on each function.
+.PP
+.B Initialisation
+.br
+To initialise the library, call
+.BR ipq_create_handle (3).
+This will attempt to bind to the Netlink socket used by ip_queue and
+return an opaque context handle for subsequent library calls.
+.PP
+.B Setting the Queue Mode
+.br
+.BR ipq_set_mode (3)
+allows the application to specify whether packet metadata, or packet
+payloads as well as metadata are copied to userspace. It is also used to
+initially notify ip_queue that an application is ready to receive queue
+messages.
+.PP
+.B Receiving Packets from the Queue
+.br
+.BR ipq_read (3)
+waits for queue messages to arrive from ip_queue and copies
+them into a supplied buffer.
+Queue messages may be
+.I packet messages
+or
+.I error messages.
+.PP
+The type of packet may be determined with
+.BR ipq_message_type (3).
+.PP
+If it's a packet message, the metadata and optional payload may be retrieved with
+.BR ipq_get_packet (3).
+.PP
+To retrieve the value of an error message, use
+.BR ipq_get_msgerr (3).
+.PP
+.B Issuing Verdicts on Packets
+.br
+To issue a verdict on a packet, and optionally return a modified version
+of the packet to the kernel, call
+.BR ipq_set_verdict (3).
+.PP
+.B Error Handling
+.br
+An error string corresponding to the current value of the internal error
+variable
+.B ipq_errno
+may be obtained with
+.BR ipq_errstr (3).
+.PP
+For simple applications, calling
+.BR ipq_perror (3)
+will print the same message as
+.BR ipq_errstr (3),
+as well as the string corresponding to the global
+.B errno
+value (if set) to stderr.
+.PP
+.B Cleaning Up
+.br
+To free up the Netlink socket and destroy resources associated with
+the context handle, call
+.BR ipq_destroy_handle (3).
+.SH SUMMARY
+.TP 4
+.BR ipq_create_handle (3)
+Initialise library, return context handle.
+.TP
+.BR ipq_set_mode (3)
+Set the queue mode, to copy either packet metadata, or payloads
+as well as metadata to userspace.
+.TP
+.BR ipq_read (3)
+Wait for a queue message to arrive from ip_queue and read it into
+a buffer.
+.TP
+.BR ipq_message_type (3)
+Determine message type in the buffer.
+.TP
+.BR ipq_get_packet (3)
+Retrieve a packet message from the buffer.
+.TP
+.BR ipq_get_msgerr (3)
+Retrieve an error message from the buffer.
+.TP
+.BR ipq_set_verdict (3)
+Set a verdict on a packet, optionally replacing its contents.
+.TP
+.BR ipq_errstr (3)
+Return an error message corresponding to the internal ipq_errno variable.
+.TP
+.BR ipq_perror (3)
+Helper function to print error messages to stderr.
+.TP
+.BR ipq_destroy_handle (3)
+Destroy context handle and associated resources.
+.SH EXAMPLE
+The following is an example of a simple application which receives
+packets and issues NF_ACCEPT verdicts on each packet.

+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

+# using a macro with the same name in our local m4/libtool.m4 it'll

+#
+#
+# This fingerprint database is adapted from Michal Zalewski's p0f passive
+# operating system package. The last database sync was from a Nov 3 2003
+# p0f.fp.
+#
+#
+# Each line in this file specifies a single fingerprint. Please read the
+# information below carefully before attempting to append any signatures
+# reported as UNKNOWN to this file to avoid mistakes.
+#
+# We use the following set metrics for fingerprinting:
+#
+# - Window size (WSS) - a highly OS dependent setting used for TCP/IP
+# performance control (max. amount of data to be sent without ACK).
+# Some systems use a fixed value for initial packets. On other
+# systems, it is a multiple of MSS or MTU (MSS+40). In some rare
+# cases, the value is just arbitrary.
+#
+# NEW SIGNATURE: if p0f reported a special value of 'Snn', the number
+# appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn'
+# means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the
+# value of nn is not fixed (unlikely), just copy the Snn or Tnn token
+# literally. If you know this device has a simple stack and a fixed
+# MTU, you can however multiply S value by MSS, or T value by MSS+40,
+# and put it instead of Snn or Tnn.
+#
+# If WSS otherwise looks like a fixed value (for example a multiple
+# of two), or if you can confirm the value is fixed, please quote
+# it literally. If there's no apparent pattern in WSS chosen, you
+# should consider wildcarding this value.
+#
+# - Overall packet size - a function of all IP and TCP options and bugs.
+#
+# NEW SIGNATURE: Copy this value literally.
+#
+# - Initial TTL - We check the actual TTL of a received packet. It can't
+# be higher than the initial TTL, and also shouldn't be dramatically
+# lower (maximum distance is defined as 40 hops).
+#
+# NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally.
+# You need to determine the initial TTL. The best way to do it is to
+# check the documentation for a remote system, or check its settings.
+# A fairly good method is to simply round the observed TTL up to
+# 32, 64, 128, or 255, but it should be noted that some obscure devices
+# might not use round TTLs (in particular, some shoddy appliances use
+# "original" initial TTL settings). If not sure, you can see how many
+# hops you're away from the remote party with traceroute or mtr.
+#
+# - Don't fragment flag (DF) - some modern OSes set this to implement PMTU
+# discovery. Others do not bother.
+#
+# NEW SIGNATURE: Copy this value literally.
+#
+# - Maximum segment size (MSS) - this setting is usually link-dependent. P0f
+# uses it to determine link type of the remote host.
+#
+# NEW SIGNATURE: Always wildcard this value, except for rare cases when
+# you have an appliance with a fixed value, know the system supports only
+# a very limited number of network interface types, or know the system
+# is using a value it pulled out of nowhere. Specific unique MSS
+# can be used to tell Google crawlbots from the rest of the population.
+#
+# - Window scaling (WSCALE) - this feature is used to scale WSS.
+# It extends the size of a TCP/IP window to 32 bits. Some modern
+# systems implement this feature.
+#
+# NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set
+# to zero or other low value. There's usually no need to wildcard this
+# parameter.
+#
+# - Timestamp - some systems that implement timestamps set them to
+# zero in the initial SYN. This case is detected and handled appropriately.
+#
+# - Selective ACK permitted - a flag set by systems that implement
+# selective ACK functionality.
+#
+# - The sequence of TCP all options (MSS, window scaling, selective ACK
+# permitted, timestamp, NOP). Other than the options previously
+# discussed, p0f also checks for timestamp option (a silly
+# extension to broadcast your uptime ;-), NOP options (used for
+# header padding) and sackOK option (selective ACK feature).
+#
+# NEW SIGNATURE: Copy the sequence literally.
+#
+# To wildcard any value (except for initial TTL or TCP options), replace
+# it with '*'. You can also use a modulo operator to match any values
+# that divide by nnn - '%nnn'.
+#
+# Fingerprint entry format:
+#
+# wwww:ttt:D:ss:OOO...:OS:Version:Subtype:Details
+#
+# wwww - window size (can be *, %nnn, Snn or Tnn). The special values
+# "S" and "T" which are a multiple of MSS or a multiple of MTU
+# respectively.
+# ttt - initial TTL
+# D - don't fragment bit (0 - not set, 1 - set)
+# ss - overall SYN packet size
+# OOO - option value and order specification (see below)
+# OS - OS genre (Linux, Solaris, Windows)
+# Version - OS Version (2.0.27 on x86, etc)
+# Subtype - OS subtype or patchlevel (SP3, lo0)
+# details - Generic OS details
+#
+# If OS genre starts with '*', p0f will not show distance, link type
+# and timestamp data. It is useful for userland TCP/IP stacks of
+# network scanners and so on, where many settings are randomized or
+# bogus.
+#
+# If OS genre starts with @, it denotes an approximate hit for a group
+# of operating systems (signature reporting still enabled in this case).
+# Use this feature at the end of this file to catch cases for which
+# you don't have a precise match, but can tell it's Windows or FreeBSD
+# or whatnot by looking at, say, flag layout alone.
+#
+# Option block description is a list of comma or space separated
+# options in the order they appear in the packet:
+#
+# N - NOP option
+# Wnnn - window scaling option, value nnn (or * or %nnn)
+# Mnnn - maximum segment size option, value nnn (or * or %nnn)
+# S - selective ACK OK
+# T - timestamp
+# T0 - timestamp with a zero value
+#
+# To denote no TCP options, use a single '.'.
+#
+# Please report any additions to this file, or any inaccuracies or
+# problems spotted, to the maintainers: lcamtuf@coredump.cx,
+# frantzen@openbsd.org and bugs@openbsd.org with a tcpdump packet
+# capture of the relevant SYN packet(s)

+#
+#
+# WARNING WARNING WARNING
+# -----------------------
+#
+# Do not add a system X as OS Y just because NMAP says so. It is often
+# the case that X is a NAT firewall. While nmap is talking to the
+# device itself, p0f is fingerprinting the guy behind the firewall
+# instead.
+#
+# When in doubt, use common sense, don't add something that looks like
+# a completely different system as Linux or FreeBSD or LinkSys router.
+# Check DNS name, establish a connection to the remote host and look
+# at SYN+ACK - does it look similar?
+#
+# Some users tweak their TCP/IP settings - enable or disable RFC1323
+# functionality, enable or disable timestamps or selective ACK,
+# disable PMTU discovery, change MTU and so on. Always compare a new rule
+# to other fingerprints for this system, and verify the system isn't
+# "customized" before adding it. It is OK to add signature variants
+# caused by a commonly used software (personal firewalls, security
+# packages, etc), but it makes no sense to try to add every single
+# possible /proc/sys/net/ipv4 tweak on Linux or so.
+#
+# KEEP IN MIND: Some packet firewalls configured to normalize outgoing
+# traffic (OpenBSD pf with "scrub" enabled, for example) will, well,
+# normalize packets. Signatures will not correspond to the originating
+# system (and probably not quite to the firewall either).
+#
+# NOTE: Try to keep this file in some reasonable order, from most to
+# least likely systems. This will speed up operation. Also keep most
+# generic and broad rules near the end.
