+		    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.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	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.

+
+0.Introduction
+==============
+
+ The conntrack-tools package contains two programs:
+
+  - conntrack:	the command line interface to interact with the connection 
+		tracking system.
+
+  - conntrackd: the connection tracking userspace daemon that can be used to
+  		deploy highly available GNU/Linux firewalls and collect 
+		statistics of the firewall use.
+
+ Although their names are similar, they are used for different tasks.
+
+1. Requirements
+===============
+
+ You have to install the following software in order to get the conntrack-tools
+ working, make sure that you have installed them correctly before going forward:
+
+ o linux kernel version >= 2.6.18 (http://www.kernel.org) that, at least,
+   has support for:
+
+     - connection tracking system
+	   CONFIG_NF_CONNTRACK=m
+	   CONFIG_NF_CONNTRACK_IPV4=m
+	   CONFIG_NF_CONNTRACK_IPV6=m (if you need IPv6 support)
+
+     - nfnetlink
+           CONFIG_NETFILTER_NETLINK=m
+
+     - ctnetlink (nf_conntrack_netlink)
+           CONFIG_NF_CT_NETLINK=m
+
+     - connection tracking event notification API
+           CONFIG_NF_CONNTRACK_EVENTS=y
+
+     	(To check that the event API is enabled in the kernel, make sure
+	 you have loaded nf_netlink_conntrack module, run conntrack -E and 
+	 generate traffic, you should see network events)
+
+ o libnfnetlink: the netfilter netlink library available at:
+
+     <http://www.netfilter.org/projects/libnfnetlink/files/>
+
+ o libnetfilter_conntrack: the netfilter conntrack library available at:
+
+     <http://www.netfilter.org/projects/libnetfilter_conntrack/files/>
+
+2.Compilation and Installation
+==============================
+
+ To compile and install conntrack-tools just follow the classical steps:
+
+	$ ./configure --prefix=/usr
+	$ make
+	# make install
+
+ Up to this point, the command line interface `conntrack' is ready for use,
+ see man conntrack(8). However, the userspace daemon so-called `conntrackd' 
+ requires some magic spells to get it working.
+
+ *Fedora users*: If you are trying to install the libraries in /usr/local/,
+ do not forget to do the following things:
+
+	* PKG_CONFIG_PATH=/usr/local/lib/pkgconfig; export PKG_CONFIG_PATH
+ 	* Add `/usr/local/lib' to your /etc/ld.so.conf file and run `ldconfig'
+ 
+ Check `ldd' for trouble-shooting, read <http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html#AEN70> for more information on how libraries work.
+
+3.How-to use and set up
+=======================
+
+ Please, refer to the user manual for further information on how to use and
+ set up the conntrack-tools. This user manual is is available in the 
+ documentation directory included in this tarball.

+# 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.

+\`configure' configures conntrack-tools 1.2.1 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]

+.SH NAME
+conntrack \- command line interface for netfilter connection tracking
+.SH SYNOPSIS
+.BR "conntrack -L [table] [options] [-z]"
+.br
+.BR "conntrack -G [table] parameters"
+.br
+.BR "conntrack -D [table] parameters"
+.br
+.BR "conntrack -I [table] parameters"
+.br
+.BR "conntrack -U [table] parameters"
+.br
+.BR "conntrack -E [table] [options]"
+.br
+.BR "conntrack -F [table]"
+.br
+.BR "conntrack -C [table]"
+.br
+.BR "conntrack -S "
+.SH DESCRIPTION
+.B conntrack
+provides a full featured userspace interface to the netfilter connection tracking system that is intended to replace the old /proc/net/ip_conntrack interface. This tool can be used to search, list, inspect and maintain the connection tracking subsystem of the Linux kernel.
+Using 
+.B conntrack
+, you can dump a list of all (or a filtered selection of) currently tracked
+connections, delete connections from the state table, and even add new ones.
+.PP
+In addition, you can also monitor connection tracking events, e.g. show an
+event message (one line) per newly established connection.
+.SH TABLES
+The connection tracking subsystem maintains two internal tables:
+.TP
+.BR "conntrack" :
+This is the default table.  It contains a list of all currently tracked
+connections through the system.  If you don't use connection tracking
+exemptions (NOTRACK iptables target), this means all connections that go
+through the system.
+.TP
+.BR "expect" :
+This is the table of expectations.  Connection tracking expectations are the
+mechanism used to "expect" RELATED connections to existing ones.  Expectations
+are generally used by "connection tracking helpers" (sometimes called
+application level gateways [ALGs]) for more complex protocols such as FTP,
+SIP, H.323.
+.SH OPTIONS
+The options recognized by 
+.B conntrack
+can be divided into several different groups.
+.SS COMMANDS
+These options specify the particular operation to perform.  Only one of them
+can be specified at any given time.
+.TP
+.BI "-L --dump "
+List connection tracking or expectation table
+.TP
+.BI "-G, --get "
+Search for and show a particular (matching) entry in the given table.
+.TP
+.BI "-D, --delete "
+Delete an entry from the given table.
+.TP
+.BI "-I, --create "
+Create a new entry from the given table.
+.TP
+.BI "-U, --update "
+Update an entry from the given table.
+.TP
+.BI "-E, --event "
+Display a real-time event log.
+.TP
+.BI "-F, --flush "
+Flush the whole given table
+.TP
+.BI "-C, --count "
+Show the table counter.
+.TP
+.BI "-S, --stats "
+Show the in-kernel connection tracking system statistics.
+.SS PARAMETERS
+.TP
+.BI "-z, --zero "
+Atomically zero counters after reading them.  This option is only valid in
+combination with the "-L, --dump" command options.
+.TP
+.BI "-o, --output [extended,xml,timestamp,id,ktimestamp] "
+Display output in a certain format. With the extended output option, this tool
+displays the layer 3 information. With ktimestamp, it displays the in-kernel
+timestamp available since 2.6.38 (you can enable it via echo 1 >
+/proc/sys/net/netfilter/nf_conntrack_timestamp).
+.TP
+.BI "-e, --event-mask " "[ALL|NEW|UPDATES|DESTROY][,...]"
+Set the bitmask of events that are to be generated by the in-kernel ctnetlink
+event code.  Using this parameter, you can reduce the event messages generated
+by the kernel to those types to those that you are actually interested in.
+.
+This option can only be used in conjunction with "-E, --event".
+.TP
+.BI "-b, --buffer-size " "value (in bytes)"
+Set the Netlink socket buffer size. This option is useful if the command line
+tool reports ENOBUFS errors. If you do not pass this option, the default value
+available at /proc/sys/net/core/rmem_default is used. The tool reports this
+problem if your process is too slow to handle all the event messages or, in 
+other words, if the amount of events are big enough to overrun the socket 
+buffer. Note that using a big buffer reduces the chances to hit ENOBUFS, 
+however, this results in more memory consumption.
+.
+This option can only be used in conjunction with "-E, --event".
+.SS FILTER PARAMETERS
+.TP
+.BI "-s, --orig-src " IP_ADDRESS
+Match only entries whose source address in the original direction equals the one specified as argument.
+.TP
+.BI "-d, --orig-dst " IP_ADDRESS
+Match only entries whose destination address in the original direction equals the one specified as argument.
+.TP
+.BI "-r, --reply-src " IP_ADDRESS
+Match only entries whose source address in the reply direction equals the one specified as argument.
+.TP
+.BI "-q, --reply-dst " IP_ADDRESS
+Match only entries whose destination address in the reply direction equals the one specified as argument.
+.TP
+.BI "-p, --proto " "PROTO "
+Specify layer four (TCP, UDP, ...) protocol.
+.TP
+.BI "-f, --family " "PROTO"
+Specify layer three (ipv4, ipv6) protocol
+This option is only required in conjunction with "-L, --dump". If this option is not passed, the default layer 3 protocol will be IPv4.
+.TP
+.BI "-t, --timeout " "TIMEOUT"
+Specify the timeout.
+.TP
+.BI "-m, --mark " "MARK[/MASK]"
+Specify the conntrack mark.  Optionally, a mask value can be specified.
+In "--update" mode, this mask specifies the bits that should be zeroed before XORing
+the MARK value into the ctmark.
+Otherwise, the mask is logically ANDed with the existing mark before the comparision.
+In "--create" mode, the mask is ignored.
+.TP
+.BI "-c, --secmark " "SECMARK"
+Specify the conntrack selinux security mark.
+.TP
+.BI "-u, --status " "[ASSURED|SEEN_REPLY|FIXED_TIMEOUT|EXPECTED|UNSET][,...]"
+Specify the conntrack status.
+.TP
+.BI "-n, --src-nat "
+Filter source NAT connections. 
+.TP
+.BI "-g, --dst-nat "
+Filter destination NAT connections. 
+.TP
+.BI "-j, --any-nat "
+Filter any NAT connections.
+.TP
+.BI "-w, --zone "
+Filter by conntrack zone. See iptables CT target for more information.
+.TP
+.BI "--tuple-src " IP_ADDRESS
+Specify the tuple source address of an expectation.
+.TP
+.BI "--tuple-dst " IP_ADDRESS
+Specify the tuple destination address of an expectation.
+.TP
+.BI "--mask-src " IP_ADDRESS
+Specify the source address mask of an expectation.
+.TP
+.BI "--mask-dst " IP_ADDRESS
+Specify the destination address mask of an expectation.

+.SH NAME
+conntrackd \- netfilter connection tracking user-space daemon
+.SH SYNOPSIS
+.BR "conntrackd [options]"
+.SH DESCRIPTION
+.B conntrackd
+is the user-space daemon for the netfilter connection tracking system. This daemon synchronizes connection tracking states between several replica firewalls. Thus,
+.B conntrackd 
+can be used to deploy highly available stateful firewalls. The daemon supports Primary-Backup and Multiprimary setups. The daemon can also be used as statistics collector.
+.SH OPTIONS
+The options recognized by
+.B conntrackd
+can be divided into several different groups.
+.SS MODES
+These options specify the particular operation mode in which conntrackd runs. Only one of them can be specified at any given time.
+.TP
+.BI "-d "
+Run conntrackd in daemon mode.
+.SS CLIENT COMMANDS
+.B conntrackd 
+can be used in client mode to request several information and operations to a running daemon
+.TP
+.BI "-i "[ct|expect]"
+Dump the internal cache, i.e. show local states
+.TP
+.BI "-e "[ct|expect]"
+Dump the external cache, i.e. show foreign states
+.TP
+.BI "-x "
+Display output in XML format. This option is only valid in combination
+with "-i" and "-e" parameters.
+.TP
+.BI "-f " "[|internal|external]"
+Flush the internal and/or external cache
+.TP
+.BI "-F [ct|expect]"
+Flush the kernel conntrack table (if you use a Linux kernel >= 2.6.29, this
+option will not flush your internal and external cache).
+.TP
+.BI "-c "
+Commit external cache to conntrack table.
+.TP
+.BI "-B "
+Force a bulk send to other replica firewalls. With this command, you will
+ask conntrackd to send the state-entries that it owns to others.
+.TP
+.BI "-n "
+Request resync with other node (only FT-FW and NOTRACK modes).
+.TP
+.BI "-k "
+Kill the daemon
+.TP
+.BI "-s " "[|network|cache|runtime|link|rsqueue|process|queue|ct|expect]"
+Dump statistics. If no parameter is passed, it displays the general statistics.
+If "network" is passed as parameter it displays the networking statistics.
+If "cache" is passed as parameter, it shows the extended cache statistics.
+If "runtime" is passed as parameter, it shows the run-time statistics.
+If "process" is passed as parameter, it shows existing child processes (if any).
+If "queue" is passed as parameter, it shows queue statistics.
+If "ct" is passed, it displays the general statistics.
+If "expect" is passed as parameter, it shows expectation statistics.
+.TP
+.BI "-R " "[ct|expect]"
+Force a resync against the kernel connection tracking table
+.TP
+.BI "-t "
+Reset the in-kernel timers (See PurgeTimeout clause)
+.TP
+.BI "-v "
+Display version information.
+.TP
+.BI "-h "
+Display help information.
+.TP
+.BI "-C config file"
+Configuration file path.
+.TP
+.SH DIAGNOSTICS
+The exit code is 0 for correct function. Errors cause an exit code of 1.
+.SH EXAMPLES
+The following example are illustrative, for a real use in a firewall fail-over,
+check the primary-backup.sh script that comes with the sources.
+.TP
+.B conntrackd \-d
+Runs conntrackd in daemon and synchronization mode
+.TP
+.B conntrackd \-i
+Dumps the states held in the internal cache, i.e. those handled by this firewall
+.TP
+.B conntrackd \-e
+Dumps the states held in the external cache, i.e. those handled by other replica firewalls
+.TP
+.B conntrackd \-c
+Commits the external cache into the kernel connection tracking system. This is used to inject the state so that the connections can be recovered during the failover.
+.SH DEPENDENCIES
+This daemon requires a Linux kernel version >= 2.6.18. TCP window tracking support requires >= 2.6.22, otherwise you have to disable it. Helpers are fully supported since >= 2.6.25, however, if you use any previous version, depending on the protocol helper and your setup (e.g. if you setup performs NAT sequence adjustments or not), your help connection may be successfully recovered.
+.TP
+There are several unsupported stateful iptables matches such as recent, connbytes and the quota matches which gather internal information to operate. Since that information does not belong to the domain of the connection tracking system, connections affected by those matches may not be fully recovered during the takeover.
+.TP
+The daemon requires a Linux kernel version >= 2.6.26 to support kernel-space event filtering. Otherwise, all the event filtering is done in userspace with the corresponding extra overhead. If you are not using the Filter clause in the configuration file, ignore this notice.
+.SH INCOMPATIBILITIES
+During the 0.9.9 development, some important changes in the replication message format were introduced. Therefore, conntrackd >= 0.9.9 will not work appropriately with conntrackd <= 0.9.8. This should not be a problem if you use the same
+conntrackd version in all the firewall replica nodes.

+  If you find any error or imprecision in this document, please send an email
+  to the author, it will be appreciated.</para>
+
+  <para>In this document, the author assumes that the reader is familiar with firewalling concepts and iptables in general. If this is not your case, I suggest you to read the iptables documentation before going ahead. Moreover, the reader must also understand the difference between <emphasis>stateful</emphasis> and <emphasis>stateless</emphasis> firewalls. If this is not your case, I strongly suggest you to read the article <ulink url="http://people.netfilter.org/pablo/docs/login.pdf">Netfilter's Connection Tracking System</ulink> published in <emphasis>:login; the USENIX magazine</emphasis>. That document contains a general description that should help to clarify the concepts.</para>
+
+<para>If you do not fulfill the previous requirements, this documentation is likely to be a source of frustration. Probably, you wonder why I'm insisting on these prerequisites too much, the fact is that if your iptables rule-set is <emphasis>stateless</emphasis>, it is very likely that the <emphasis>conntrack-tools</emphasis> will not be of any help for you. You have been warned!</para>

+ <chapter id="what"><title>What are the conntrack-tools?</title>
+
+  <para>The conntrack-tools are a set of free software tools for GNU/Linux that allow system administrators interact, from user-space, with the in-kernel <ulink url="http://people.netfilter.org/pablo/docs/login.pdf">Connection Tracking System</ulink>, which is the module that enables stateful packet inspection for iptables. Probably, you did not hear about this module so far. However, if any of the rules of your rule-set use the <emphasis>state</emphasis> or <emphasis>ctstate</emphasis> iptables matches, you are indeed using it.

+   in the cluster as we do not know which one would be the next to filter a
+   packet. This setup goes against the design of stateful firewalls as we
+   define the filtering policy based on flows, not in packets anymore.
+   </para>
+  </listitem>
+ </itemizedlist>
+
+ <para>As for 0.9.8, the design of <emphasis>conntrackd</emphasis> allows you

+
+ <para>On the other hand, the asymmetric scenario may work if your setup 
+ fulfills several strong assumptions. However, in the opinion of the author

+
+ <para>It is possible to disable the external cache. Thus,

+
+ <para>You can also use this option with the NOTRACK and ALARM modes. This

+

+

+ content of the packet, otherwise filtering by layer 3 and 4 selectors
+ like addresses and ports become a real nightmare. Netfilter already
+ provides the so-called <emphasis>helpers</emphasis> that track this
+ protocol  aspects to allow deploying appropriate filtering. These
+ helpers create <emphasis>expectation</emphasis> entries that
+ represent expected traffic that will arrive to the firewall according
+ to the inspected packets.</para>
+
+ <para>In case that you have enabled tracking of these protocols, you
+ may want to enable the state-synchronization of expectation as well.
+ Thus, established flows for this specific protocols will not suffer
+ any disruption.</para>
+
+ <para>To enable the expectation support in the configuration file, you
+ have to use the following option:</para>
+
+ <programlisting>
+Sync {
+       ...
+       Options {
+               ExpectationSync {

+                       sip
+                       h323
+               }
+       }
+}</programlisting>
+
+ <para>The example above enables the synchronization of the expectations
+ for the FTP, SIP and H.323 helpers.</para>
+
+ <para>In my testbed, there are two firewalls in a primary-backup
+ configuration running keepalived. They use a couple of floating cluster
+ IP address (192.168.0.100 and 192.168.1.100) that are used by the client.
+ These firewalls protect one FTP server (192.168.1.2) that will be accessed
+ by one client.</para>
+
+ <para>In ASCII art, it looks like this:</para>
+
+ <programlisting>

+
+ <para>This is the rule-set for the firewalls:</para>

+	# filter-sets in positive or negative logic depending on your needs.
+	# You can select if conntrackd filters the event messages from 
+	# user-space or kernel-space. The kernel-space event filtering
+	# saves some CPU cycles by avoiding the copy of the event message
+	# from kernel-space to user-space. The kernel-space event filtering
+	# is prefered, however, you require a Linux kernel >= 2.6.29 to

+  To use rbtrees you'll have to implement your own insert and search cores.
+  This will avoid us to use callbacks and to drop drammatically performances.
+  I know it's not the cleaner way,  but in C (not in C++) to get
+  performances and genericity...
+
+  Some example of insert and search follows here. The search is a plain
+  normal search over an ordered tree. The insert instead must be implemented
+  int two steps: as first thing the code must insert the element in
+  order as a red leaf in the tree, then the support library function
+  rb_insert_color() must be called. Such function will do the
+  not trivial work to rebalance the rbtree if necessary.

+.TH NFCT 8 "Feb 29, 2012" "" ""
+
+.\" Man page written by Pablo Neira Ayuso <pablo@netfilter.org> (Feb 2012)
+
+.SH NAME
+nfct \- command line tool to interact with the connection tracking system
+.SH SYNOPSIS
+.BR "nfct subsystem command [parameters]"
+.SH DESCRIPTION
+.B nfct
+is the command line tool that allows you Netfilter's manipulate Connection Tracking System.
+.SH SUBSYS
+By the time this manpage has been written, the supported subsystem are
+.B timeout
+.TP
+.BI "timeout "
+The timeout subsystem allows you to define fine-grain timeout policies.
+.TP
+.BI "version "
+Displays the version information.
+.TP
+.BI "help "
+Displays the help message.
+.SH TIMEOUT SUBSYSTEM
+.TP
+.BI "list "
+List the existing timeout policies.
+.TP
+.BI "add "
+Add new timeout policy.
+.TP
+.BI "delete "
+Delete timeout policy.
+.TP
+.BI "get "
+Get existing timeout policy.
+.SH EXAMPLE
+.TP
+.B nfct timeout add test-tcp inet tcp established 100 close 10 close_wait 10
+.TP
+This creates a timeout policy for tcp using 100 seconds for the ESTABLISHED state, 10 seconds for CLOSE state and 10 seconds for the CLOSE_WAIT state.
+.TP
+Then, you can attach the timeout policy with the iptables CT target:
+.TP
+.B iptables -I PREROUTING -t raw -p tcp -j CT --timeout test-tcp
+.TP
+.B iptables -I OUTPUT -t raw -p tcp -j CT --timeout test-tcp
+.TP
+You can test that the timeout policy with:
+.TP
+.B conntrack -E -p tcp
+.TP
+It should display:
+.TP
+.B [UPDATE] tcp      6 100 ESTABLISHED src=192.168.39.100 dst=57.126.1.20 sport=56463 dport=80 src=57.126.1.20 dst=192.168.39.100 sport=80 dport=56463 [ASSURED]
+.SH SEE ALSO
+.BR iptables (8), conntrack (8)
+.SH BUGS
+Please, report them to netfilter-devel@vger.kernel.org or file a bug in
+Netfilter's bugzilla (https://bugzilla.netfilter.org).
+.SH AUTHORS
+Pablo Neira Ayuso wrote and maintains the nfct tool.

+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.
