You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

You can override the # shellvar-default of CFLAGS of course. The order of arguments stems from # the explicit macros like AX_CFLAGS_WARN_ALL. # # The cousin AX_CXXFLAGS_GCC_OPTION would check for an option to add to # CXXFLAGS - and it uses the autoconf setup for C++ instead of C (since it # is possible to use different compilers for C and C++). # # The macro is a lot simpler than any special AX_CFLAGS_* macro (or # ax_cxx_rtti.m4 macro) but allows to check for arbitrary options. # However, if you use this macro in a few places, it would be great if you # would make up a new function-macro and submit it to the ac-archive. # # - $1 option-to-check-for : required ("-option" as non-value) # - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case) # - $3 action-if-found : add value to shellvariable # - $4 action-if-not-found : nothing # # Note: in earlier versions, $1-$2 were swapped. We try to detect the # situation and accept a $2=~/-/ as being the old option-to-check-for. # # There are other variants that emerged from the original macro variant # which did just test an option to be possibly added. However, some # compilers accept an option silently, or possibly for just another option # that was not intended. Therefore, we have to do a generic test for a # compiler family. For gcc we check "-pedantic" being accepted which is # also understood by compilers who just want to be compatible with gcc # even when not being made from gcc sources. # # See also: AX_CFLAGS_SUN_OPTION, AX_CFLAGS_HPUX_OPTION, # AX_CFLAGS_AIX_OPTION, and AX_CFLAGS_IRIX_OPTION. # # LICENSE # # Copyright (c) 2008 Guido U.

Section 9 of the GPL V2 acknowledges that the Free Software Foundation may publish revised and/or new versions of the GPL V2 from time to time. Section 9 further states that a licensee of a program subject to the GPL V2 could be free to use any such revised and/or new versions under two different scenarios: 1. "Failure to Specify." Section 9 of the GPL V2 allows a licensee of a program governed by an unspecified version of the General Public License to choose any version of the General Public License ever published by the Free Software Foundation to govern his or her use of such program. This provision is not applicable to your use of SNORT because we have expressly stated in a number of instances that any third party's use, modification or distribution of SNORT is governed by GPL V2. 2. "Any Later Version." At the end of the terms and condition of the GPL V2 is a section called "How to Apply these Terms to Your New Program," which provides guidance to a developer on how to apply the GPL V2 to a third party's use, modification and/or distribution of his/her program. Among other things, this guidance suggests that the developer attach certain notices to the program. Of particular importance is the following notice: "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." Thus if a developer follows strictly the guidance provided by the Free Software Foundation, Section 9 of the GPL V2 provides the licensee the option to either use, modify or distribute the program under GPL V2 or under any later version published by the Free Software Foundation. SNORT is an open source project that is governed exclusively by the GPL V2 and any third party desiring to use, modify or distribute SNORT must do so by strictly following the terms and conditions of GPL V2. Anyone using, modifying or distributing SNORT does not have the option to chose to use, modify or distribute SNORT under any revised or new version of the GPL, including without limitation, the GNU General Public License Version 3. For ease of reference, the comparable notice that is used with SNORT (contained in the 'README' file) is as follows: "This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License Version 2 as published by the Free Software Foundation. You may not use, modify or distribute this program under any other version of the GNU General Public License." If you have any questions about this statement, please feel free to email snort-info@snort.org. ***************************************************************************** GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU 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 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. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 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. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

The DAQ replaces direct calls to libpcap functions with an abstraction layer that facilitates operation on a variety of hardware and software interfaces without requiring changes to Snort. It is possible to select the DAQ type and mode when invoking Snort to perform pcap readback or inline operation, etc. The DAQ library may be useful for other packet processing applications and the modular nature allows you to build new modules for other platforms. This README summarizes the important things you need to know to use the DAQ. Building the DAQ Library and DAQ Modules ======================================== The DAQ is bundled with Snort but must be built first using these steps: ./configure make sudo make install This will build and install both static and dynamic DAQ modules. Note that pcap >= 1.0.0 is required. pcap 1.1.1 is available at the time of this writing and is recommended. Also, libdnet is required for IPQ and NFQ DAQs. If you get a relocation error trying to build those DAQs, you may need to reinstall libdnet and configure it with something like this: ./configure "CFLAGS=-fPIC -g -O2" You may also experience problems trying to find the dynamic dnet library because it isn't always named properly. Try creating a link to the shared library (identified by its .x or .x.y etc. extension) with the same name but with ".so" inserted as follows: $ ln -s libdnet.1.1 libdnet.so.1.1 $ ldconfig -Rv /usr/local/lib 2>&1 | grep dnet Adding /usr/local/lib/libdnet.so.1.1 Alternatively, you should be able to fix both issues as follows: libtoolize --copy --force aclocal -I config autoheader autoconf automake --foreign When the DAQ library is built, both static and dynamic flavors will be generated. The various DAQ modules will be built if the requisite headers and libraries are available. You can disable individual modules, etc. with options to configure. For the complete list of configure options, run: ./configure --help PCAP Module =========== pcap is the default DAQ. If snort is run w/o any DAQ arguments, it will operate as it always did using this module. These are equivalent: ./snort -i ./snort -r ./snort --daq pcap --daq-mode passive -i ./snort --daq pcap --daq-mode read-file -r You can specify the buffer size pcap uses with: ./snort --daq pcap --daq-var buffer_size=<#bytes> * The pcap DAQ does not count filtered packets. * AFPACKET Module =============== afpacket functions similar to the pcap DAQ but with better performance: ./snort --daq afpacket -i [--daq-var buffer_size_mb=<#MB>] [--daq-var debug] If you want to run afpacket in inline mode, you must craft the device string as one or more interface pairs, where each member of a pair is separated by a single colon and each pair is separated by a double colon like this: eth0:eth1 or this: eth0:eth1::eth2:eth3 By default, the afpacket DAQ allocates 128MB for packet memory. You can change this with: --daq-var buffer_size_mb=<#MB> Note that the total allocated is actually higher, here's why. Assuming the default packet memory with a snaplen of 1518, the numbers break down like this: * The frame size is 1518 (snaplen) + the size of the AFPacket header (66 bytes) = 1584 bytes. * The number of frames is 128 MB / 1518 = 84733. * The smallest block size that can fit at least one frame is 4 KB = 4096 bytes @ 2 frames per block. * As a result, we need 84733 / 2 = 42366 blocks. * Actual memory allocated is 42366 * 4 KB = 165.5 MB. NOTE: Linux kernel version 2.6.31 or higher is required for the AFPacket DAQ module due to its dependency on both TPACKET v2 and PACKET_TX_RING support. NFQ Module ========== NFQ is the new and improved way to process iptables packets: ./snort --daq nfq \ [--daq-var device=] \ [--daq-var proto=] \ [--daq-var queue=] ::= ip | eth0, etc; default is IP injection ::= ip4 | ip6 |; default is ip4 ::= 0..65535; default is 0 This module can not run unprivileged so ./snort -u -g will produce a warning and won't change user or group. Notes on iptables are given below. IPQ Module ========== IPQ is the old way to process iptables packets. It replaces the inline version available in pre-2.9 versions built with this: ./configure --enable-inline Note that layer 2 resets are not supported with the IPQ DAQ: config layer2resets[: ] Start the IPQ DAQ as follows: ./snort --daq ipq \ [--daq-var device=] \ [--daq-var proto=] \ ::= ip | eth0, etc; default is IP injection ::= ip4 | ip6; default is ip4 This module can not run unprivileged so ./snort -u -g will produce a warning and won't change user or group. Notes on iptables are given below. IPFW Module =========== IPFW is available for BSD systems. It replaces the inline version available in pre-2.9 versions built with this: ./configure --enable-ipfw This command line argument is no longer supported: ./snort -J Instead, start Snort like this: ./snort --daq ipfw [--daq-var port=] ::= 1..65535; default is 8000 * IPFW only supports ip4 traffic. Notes on FreeBSD and OpenBSD are given below. Dump Module =========== The dump DAQ allows you to test the various inline mode features available in 2.9 Snort like injection and normalization. ./snort -i --daq dump ./snort -r --daq dump By default a file named inline-out.pcap will be created containing all packets that passed through or were generated by snort. You can optionally specify a different name. ./snort --daq dump --daq-var file= dump uses the pcap daq for packet acquisition. It therefore does not count filtered packets (a pcap limitation). Note that the dump DAQ inline mode is not an actual inline mode. Furthermore, you will probably want to have the pcap DAQ acquire in another mode like this: ./snort -r -Q --daq dump --daq-var load-mode=read-file ./snort -i -Q --daq dump --daq-var load-mode=passive Netmap Module ============= The netmap project is a framework for very high speed packet I/O. It is available on both FreeBSD and Linux with varying amounts of preparatory setup required. Specific notes for each follow. ./snort --daq netmap -i [--daq-var debug] If you want to run netmap in inline mode, you must craft the device string as one or more interface pairs, where each member of a pair is separated by a single colon and each pair is separated by a double colon like this: em1:em2 or this: em1:em2::em3:em4 Inline operation performs Layer 2 forwarding with no MAC filtering, akin to the AFPacket module's behavior. All packets received on one interface in an inline pair will be forwarded out the other interface unless dropped by the reader and vice versa. IMPORTANT: The interfaces will need to be up and in promiscuous mode in order to function ('ifconfig em1 up promisc'). The DAQ module does not currently do either of these configuration steps for itself. FreeBSD ------- In FreeBSD 10.0, netmap has been integrated into the core OS. In order to use it, you must recompile your kernel with the line device netmap added to your kernel config. Linux ----- You will need to download the netmap source code from the project's repository: https://code.google.com/p/netmap/ Follow the instructions on the project's homepage for compiling and installing the code: http://info.iet.unipi.it/~luigi/netmap/ It will involve a standalone kernel module (netmap_lin) as well as patching and rebuilding the kernel module used to drive your network adapters. The following drivers are supported under Linux at the time of writing (June 2014): e1000 e1000e forcedeth igb ixgbe r8169 virtio TODO: - Support for attaching to only a single ring (queue) on a network adapter. - Support for VALE and netmap pipes. Notes on iptables ================= These notes are just a quick reminder that you need to set up iptables to use the IPQ or NFQ DAQs. Doing so may cause problems with your network so tread carefully. The examples below are intentionally incomplete so please read the related documentation first. Here is a blog post by Marty for historical reference: http://archives.neohapsis.com/archives/snort/2000-11/0394.html You can check this out for queue sizing tips: http://www.inliniac.net/blog/2008/01/23/improving-snort_inlines-nfq-performance.html You might find useful IPQ info here: http://snort-inline.sourceforge.net/ Use this to examine your iptables: sudo /sbin/iptables -L Use something like this to set up NFQ: sudo /sbin/iptables -I [] [] -j NFQUEUE --queue-num 1 Use something like this to set up IPQ: sudo iptables -I FORWARD -j QUEUE Use something like this to "disconnect" snort: sudo /sbin/iptables -D
Be sure to start Snort prior to routing packets through NFQ with iptables. Such packets will be dropped until Snort is started. The queue-num is the number you must give Snort. If you are running on a system with both NFQ and IPQ support, you may experience some start-up failures of the sort: The solution seems to be to remove both modules from the kernel like this: modprobe -r nfnetlink_queue modprobe -r ip_queue and then install the module you want: modprobe ip_queue or: modprobe nfnetlink_queue These DAQs should be run with a snaplen of 65535 since the kernel defrags the packets before queuing. Also, no need to configure frag3. Notes on FreeBSD::IPFW ====================== Check the online manual at: http://www.freebsd.org/doc/handbook/firewalls-ipfw.html. Here is a brief example to divert icmp packets to Snort at port 8000: To enable support for divert sockets, place the following lines in the kernel configuration file: options IPFIREWALL options IPDIVERT (The file in this case was: /usr/src/sys/i386/conf/GENERIC; which is platform dependent.) You may need to also set these to use the loadable kernel modules: /etc/rc.conf: firewall_enable="YES" /boot/loader.conf: ipfw_load="YES" ipdivert_load="YES" $ dmesg | grep ipfw ipfw2 (+ipv6) initialized, divert loadable, nat loadable, rule-based forwarding disabled, default to deny, logging disabled $ kldload -v ipdivert Loaded ipdivert, id=4 $ ipfw add 75 divert 8000 icmp from any to any 00075 divert 8000 icmp from any to any $ ipfw list ... 00075 divert 8000 icmp from any to any 00080 allow icmp from any to any ... * Note that on FreeBSD, divert sockets don't work with bridges! Please refer to the following articles for more information: https://forums.snort.org/forums/support/topics/snort-inline-on-freebsd-ipfw http://freebsd.rogness.net/snort_inline/ NAT gateway can be used with divert sockets if the network environment is conducive to using NAT. The steps to set up NAT with ipfw are as follows: 1. Set up NAT with two interface em0 and em1 by adding the following to /etc/rc.conf gateway_enable="YES" natd_program="/sbin/natd" # path to natd natd_enable="YES" # Enable natd (if firewall_enable == YES) natd_interface="em0" # Public interface or IP Address natd_flags="-dynamic" # Additional flags defaultrouter="" ifconfig_em0="DHCP" ifconfig_em1="inet 192.168.1.2 netmask 255.255.255.0" firewall_enable="YES" firewall_script="/etc/rc.firewall" firewall_type="simple" Here em0 is connected to external network and em1 to host-only LAN. 2. Add the following divert rules to divert packets to Snort above and below the NAT rule in the "Simple" section of /etc/rc.firewall. ... # Inspect outbound packets (those arriving on "inside" interface) # before NAT translation. ${fwcmd} add divert 8000 all from any to any in via ${iif} case ${natd_enable} in [Yy][Ee][Ss]) if [ -n "${natd_interface}" ]; then ${fwcmd} add divert natd all from any to any via ${natd_interface} fi ;; esac ... # Inspect inbound packets (those arriving on "outside" interface) # after NAT translation that aren't blocked for other reasons, # after the TCP "established" rule. ${fwcmd} add divert 8000 all from any to any in via ${oif} Notes on OpenBSD::IPFW ====================== OpenBSD supports divert sockets as of 4.7, so we use the ipfw DAQ. Here is one way to set things up: 1. Configure the system to forward packets: $ sysctl net.inet.ip.forwarding=1 $ sysctl net.inet6.ip6.forwarding=1 (You can also put that in /etc/sysctl.conf to enable on boot.) 2. Set up interfaces $ dhclient vic1 $ dhclient vic2 3. Set up packet filter rules: $ echo "pass out on vic1 divert-packet port 9000 keep-state" > rules.txt $ echo "pass out on vic2 divert-packet port 9000 keep-state" >> rules.txt $ pfctl -v -f rules.txt 4. Analyze packets diverted to port 9000: $ ./snort --daq ipfw --daq-var port=9000 * Note that on OpenBSD, divert sockets don't work with bridges! daq-2.0.7/configure.ac0000444000175300017520000002604013643341136013737 0ustar biswparieng# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.
