Known issue / missing feature T50 5.6.7 - September 1st, 2016 * Checks for Linux on configure script * Uses compiler processor's optimizations options only for x86-64 and i?86. T50 5.6.6 - August, 2016 - Fixed a bug on command line parser. T50 5.6.3 - May 30th, 2016 * Project now compiles and installs with GNU Build System help. * Compiler option -mtune=native changed to -march=native. SSE options for i386 not necessary anymore. T50 5.5 - March 19th, 2016 * Minor fixes * Added comments to the code (for developers) T50 5.5 - March 16th, 2016 * SIGTSTP and SIGTRAP are now blocked. - Some nasty bugs based on kl0nEz discovery fixed. - A nasty bug detected by kl0nEz (shell crash!) was corrected. T50 5.5 - December 18th, 2015 + Added experimental xorshift128+ pseudo random number generator routine. T50 5.5 - December 1st, 2015 - The PRNG now generates 32 bit unsigned numbers. * t50.c changed to main.c T50 5.5 - February 3rd, 2015 ! Changed the behavior of signals from RESTART to INTERRUPT. * The raw socket is NON BLOCKING now. ! Improved command line parser: No more duplicated options accepted! --protocol is case insensitive now. - Add call to tcp_help() to usage(). * Support for RDRAND and BMI2 instruction set added. - Small bug when calculating IP address on t50.c fixed + Added some "post-mortem" debug routines * If sendto's errno is EPERM, show permission error message asking to check firewall settings. - Fixed bugs of modules memory allocations. * Code compiles fine with LLVM clang 3.x; * SSE is enabled by default in x86-64 architecture (commented on Makefile); * Changed return type of module funcions; * Small corrections on modules functions; * All files were converted to UNIX text format; * gre_encapsulation() was still not used on ospf.c; - Calls to sendto with second parameter were wrong; * Function ip_header() added to modules/ip.c. - On embeded systems the use of VLAs (Variable Length Arrays) in modules functions can be hazardous due to restricted stack space. "Differential" buffer reallocation on heap fix this problem; * cksum() 5 times faster now (summing QWORDs, DWORDs WORDs and BYTES, in that order); * Using a trick to deal with pointers of multiple types on modules functions; * New Makefile (still needs some tweaks) for better incremental compiling; * Minor fix on getOrdinalSuffix() function, no t50.c (11, 12 & 13 have a "th" suffix!). + Added comments with FIX, FIXME, NOTE prefix for better code reading. * Changed the way modules table are declared. See modules.c for advice. * Module table are not order dependant anymore! * Created src/help directory and src/include/help.h header to improve module "modularity". * Host name now can be a partial IP or name, optionally followed by "/cidr". Partial IP have the format 'a(.b(.c(.d)))'. Formats as 'a.b./cidr' are invalid. ! if a name or a full IP is given, the default cidr is 32. T50 will fail showing the message: "CIDR must be between 8 and 30.". - CIDR bug above fixed by Fernando Mercês. * socket descriptor isolated from anyone except sock.c. * "modules" just manipulates the packet buffer. main() actually sends the packet. * 'stdout' is now unbuffered on initialization.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. t50-5.6.8/Makefile.am000066400000000000000000000001671277750616000142150ustar00rootroot00000000000000SUBDIRS = src . man_MANS = doc/t50.8 EXTRA_DIST = $(man_MANS) \ doc/README.md \ doc/DOWNLOAD.md \ CHANGELOG \ LICENSE t50-5.6.8/Makefile.in000066400000000000000000000662541277750616000142370ustar00rootroot00000000000000# Makefile.in generated by automake 1.14.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2013 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__is_gnu_make = test -n '$(MAKEFILE_LIST)' && test -n '$(MAKELEVEL)' am__make_running_with_option = \ case $${target_option-} in \ ?) ;; \ *) echo "am__make_running_with_option: internal error: invalid" \ "target option '$${target_option-}' specified" >&2; \ exit 1;; \ esac; \ has_opt=no; \ sane_makeflags=$$MAKEFLAGS; \ if $(am__is_gnu_make); then \ sane_makeflags=$$MFLAGS; \ else \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ bs=\\; \ sane_makeflags=`printf '%s\n' "$$MAKEFLAGS" \ | sed "s/$$bs$$bs[$$bs $$bs ]*//g"`;; \ esac; \ fi; \ skip_next=no; \ strip_trailopt () \ { \ flg=`printf '%s\n' "$$flg" | sed "s/$$1.*$$//"`; \ }; \ for flg in $$sane_makeflags; do \ test $$skip_next = yes && { skip_next=no; continue; }; \ case $$flg in \ *=*|--*) continue;; \ -*I) strip_trailopt 'I'; skip_next=yes;; \ -*I?*) strip_trailopt 'I';; \ -*O) strip_trailopt 'O'; skip_next=yes;; \ -*O?*) strip_trailopt 'O';; \ -*l) strip_trailopt 'l'; skip_next=yes;; \ -*l?*) strip_trailopt 'l';; \ -[dEDm]) skip_next=yes;; \ -[JT]) skip_next=yes;; \ esac; \ case $$flg in \ *$$target_option*) has_opt=yes; break;; \ esac; \ done; \ test $$has_opt = yes am__make_dryrun = (target_option=n; $(am__make_running_with_option)) am__make_keepgoing = (target_option=k; $(am__make_running_with_option)) pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

F22 Raptor) is a tool designed to perform "Stress Testing". The concept started on 2001, right after release 'nb-isakmp.c', and the main goal was: - Having a tool to perform TCP/IP protocol fuzzer, covering common regular protocols, such as: ICMP, TCP and UDP. Things have changed, and the T50 became a good unique resource capable to perform "Stress Testing". And, after checking the "/usr/include/linux", some protocols were chosen to be part of its coverage: a) ICMP - Internet Control Message Protocol b) IGMP - Internet Group Management Protocol c) TCP - Transmission Control Protocol d) UDP - User Datagram Protocol Why "Stress Testing"? Well, because when people are designing a new network infra-structure (eg. Datacenter serving to Cloud Computing) they think about: a) High-Availability b) Load Balancing c) Backup Sites (Cold Sites, Hot Sites, and Warm Sites) d) Disaster Recovery e) Data Redundancy f) Service Level Agreements g) Etc... But almost nobody thinks about "Stress Testing", or even performs any test to check how the networks infra-structure behaves under stress, under overload, and under attack. Even during a Penetration Test, people prefer not running any kind of Denial-of-Service testing. Even worse, those people are missing one of the three key concepts of security that are common to risk management: - Confidentiality - Integrity - AVAILABILITY T50 was designed to perform “Stress Testing” on a variety of infra-structure network devices (Version 2.45), using widely implemented protocols, and after some requests it was was re-designed to extend the tests (as of Version 5.3), covering some regular protocols (ICMP, TCP and UDP), some infra-structure specific protocols (GRE, IPSec and RSVP), and some routing protocols (RIP, EIGRP and OSPF). This new version (Version 5.3) is focused on internal infra-structure, which allows people to test the availability of its resources, and cobering: a) Interior Gateway Protocols (Distance Vector Algorithm): 1. Routing Information Protocol (RIP) 2. Enhanced Interior Gateway Routing Protocol (EIGRP) b) Interior Gateway Protocols (Link State Algorithm): 1. Open Shortest Path First (OSPF) c) Quality-of-Service Protocols: 1. Resource ReSerVation Protocol (RSVP). d) Tunneling/Encapsulation Protocols: 1. Generic Routing Encapsulation (GRE). T50 is a powerful and unique packet injector tool, which is capable to: a) Send sequentially the following fifteen (15) protocols: 1. ICMP - Internet Control Message Protocol 2. IGMPv1 - Internet Group Management Protocol v1 3. IGMPv3 - Internet Group Management Protocol v3 4. TCP - Transmission Control Protocol 5. EGP - Exterior Gateway Protocol 6.

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.

T50 (f.k.a. F22 Raptor) is a tool designed to perform "Stress Testing". The concept started on 2001, right after release 'nb-isakmp.c', and the main goal was: - Having a tool to perform TCP/IP protocol fuzzer, covering common regular protocols, such as: ICMP, TCP and UDP. Things have changed, and the T50 became a good unique resource capable to perform "Stress Testing". And, after checking the "/usr/include/linux", some protocols were chosen to be part of its coverage: a) ICMP - Internet Control Message Protocol b) IGMP - Internet Group Management Protocol c) TCP - Transmission Control Protocol d) UDP - User Datagram Protocol Why "Stress Testing"? Well, because when people are designing a new network infra-structure (eg. Datacenter serving to Cloud Computing) they think about: a) High-Availability b) Load Balancing c) Backup Sites (Cold Sites, Hot Sites, and Warm Sites) d) Disaster Recovery e) Data Redundancy f) Service Level Agreements g) Etc... But almost nobody thinks about "Stress Testing", or even performs any test to check how the networks infra-structure behaves under stress, under overload, and under attack. Even during a Penetration Test, people prefer not running any kind of Denial-of-Service testing. Even worse, those people are missing one of the three key concepts of security that are common to risk management: - Confidentiality - Integrity - AVAILABILITY T50 was designed to perform “Stress Testing” on a variety of infra-structure network devices (Version 2.45), using widely implemented protocols, and after some requests it was was re-designed to extend the tests (as of Version 5.3), covering some regular protocols (ICMP, TCP and UDP), some infra-structure specific protocols (GRE, IPSec and RSVP), and some routing protocols (RIP, EIGRP and OSPF). This new version (Version 5.3) is focused on internal infra-structure, which allows people to test the availability of its resources, and cobering: a) Interior Gateway Protocols (Distance Vector Algorithm): 1. Routing Information Protocol (RIP) 2. Enhanced Interior Gateway Routing Protocol (EIGRP) b) Interior Gateway Protocols (Link State Algorithm): 1. Open Shortest Path First (OSPF) c) Quality-of-Service Protocols: 1. Resource ReSerVation Protocol (RSVP). d) Tunneling/Encapsulation Protocols: 1. Generic Routing Encapsulation (GRE). T50 is a powerful and unique packet injector tool, which is capable to: a) Send sequentially the following fifteen (15) protocols: 1. ICMP - Internet Control Message Protocol 2. IGMPv1 - Internet Group Management Protocol v1 3. IGMPv3 - Internet Group Management Protocol v3 4. TCP - Transmission Control Protocol 5. EGP - Exterior Gateway Protocol 6. UDP - User Datagram Protocol 7. RIPv1 - Routing Information Protocol v1 8. RIPv2 - Routing Information Protocol v2 9. DCCP - Datagram Congestion Control Protocol 10. RSVP - Resource ReSerVation Protocol 11. GRE - Generic Routing Encapsulation 12. IPSec - Internet Protocol Security (AH/ESP) 13. EIGRP - Enhanced Interior Gateway Routing Protocol 14. OSPF - Open Shortest Path First b) It is the only tool capable to encapsulate the protocols (listed above) within Generic Routing Encapsulation (GRE). c) Send an (quite) incredible amount of packets per second, making it a "second to none" tool: -> More than 1,000,000 pps of SYN Flood (+50% of the network uplink) in a 1000BASE-T Network (Gigabit Ethernet). -> More than 120,000 pps of SYN Flood (+60% of the network uplink) in a 100BASE-TX Network (Fast Ethernet). d) Perform "Stress Testing" on a variety of network infrastructure, network devices and security solutions in place. e) Simulate "Distributed Denial-of-Service" & "Denial-of-Service" attacks, validating Firewall rules, Router ACLs, Intrusion Detection System and Intrusion Prevention System policies. The main differentiator of the T50 is that it is able to send all protocols, sequentially, using one single SOCKET, besides it is capable to be used to modify network routes, letting IT Security Professionals performing advanced "Penetration Test". t50-5.6.8/doc/README.modules000066400000000000000000000322421277750616000152540ustar00rootroot00000000000000How to create a new module for T50 Suppose you want to add a new protocol for packet injection on T50. Let's say you want to add "Stream Control Transport Protocol" (SCTP). For this example I choose this protocol because it's defined in header as IPPROTO_SCTP. You can code any protocol you want. But if your protocol description (IPPROTO_xxx) isn't available on standard header files, you *MUST* create your own definition on 'src/include/defines.h' file. The IPPROTO_T50 definition, for instance, is defined there. Adding a module is a 5 step process: ** STEP 1: The first step is to create a module that re-allocate, fills the packet buffer and returns the packet buffer size to the caller. All module routines *MUST* follow the signature defined in "typedefs.h": ┌────────────────────────────────────────────────────────────────────────────────────────────────┐ │ typedef void (*module_func_ptr_t)(const struct config_options * const __restrict__, size_t *); │ └────────────────────────────────────────────────────────────────────────────────────────────────┘ Your module *MUST* be created in src/modules/ directory as 'sctp.c'. You *SHOULD* code something like this: ┌──────────────────────────────────────────────────────────────────────────────┐ │ #include /* Include all t50 definitions and prototypes. */ │ │ │ │ static void fill_sctp(void *buffer); │ │ static size_t get_sctp_buffer_size(void); │ │ │ │ /* This is the module! */ │ │ void sctp(const struct config_options * const __restrict__ co, size_t *size) │ │ { │ │ /* Working pointers to the buffer */ │ │ struct iphdr *ip; │ │ │ │ /* Get the packet size */ │ │ *size = sizeof(struct iphdr) + get_sctp_buffer_size(); │ │ │ │ /* Tries to reallocate space for the packet buffer, if necessary. */ │ │ alloc_packet(*size); │ │ │ │ /* Fill IP header */ │ │ ip = ip_header(packet, *size, │ │ │ │ fill_sctp(packet + sizeof(struct iphdr)); │ │ } │ │ │ │ /* This will fill the buffer part of sctp protocol. */ │ │ static void fill_sctp(void *buffer, size_t size) { ... } │ │ │ │ /* This is only an example! */ │ │ #define SCTP_SIZE 524 │ │ static size_t get_sctp_buffer_size(void) { return SCTP_SIZE; } │ └──────────────────────────────────────────────────────────────────────────────┘ Notice that "packet" is a global pointer to the packet buffer used by all modules. It is necessary to reallocate the buffer for every module, since the previous module who use it could leave a very small buffer behind. Any protocol specific structures, types *SHOULD* be defined in a separated header file 'sctp.h' in 'src/include/protocol/' directory and this header *MUST* be added to '/src/include/common.h' file. The prototype of the module function *MUST* be added to 'src/include/modules.h' file: ┌───────────────────────────────────────────────────────────────────────────────┐ │ extern void sctp(const struct config_options * const __restrict__, size_t *); │ └───────────────────────────────────────────────────────────────────────────────┘ Take a look at the actual modules. They are a little more complicated than this, but essentially, that's all they do. ** STEP 2: Create an entry on 'src/modules.c'. You *MUST* add a line like this before END_MODULES_TABLE declaration: ┌────────────────────────────────────────────────────────────────────────────────┐ │ MODULE_ENTRY(IPPROTO_SCTP, "SCTP","Stream Control Transport Protocol", sctp) │ │ END_MODULES_TABLE │ └────────────────────────────────────────────────────────────────────────────────┘ This way T50 now knows how to fill the packet for your protocol. ** STEP 3: Change config_options structure on 'src/config.c' and 'src/include/config.h'. Let's say that SCTP needs only one item called 'tag' (a 32 bits value) that could be a random value. You can add a new structure on config_options: ┌───────────────────────────────────────────────────────────────────────────┐ │ struct { │ │ uint32_t tag; │ │ } sctp; │ └───────────────────────────────────────────────────────────────────────────┘ OBS: The "random" part depends on the module. The macro __RND(), defined in 'src/include/defines.h' will return an random value if its parameter is 0. You acn use this on your function to garantee an random value if this 'tag' is informed as 0 or not informed at all in the command line. Now, add an OPTION_SCTP_TAG in the enumeration at the beggining of config.h file. Add a default value to config_options 'co' variable at config.c, if you need something different from 0. Add an entry called 'sctp-tag' on long_opt array to allow you to change this value through the command line: ┌───────────────────────────────────────────────────────────────────────────┐ │ { "sctp-tag", required_argument, NULL, OPTION_SCTP_TAG }, │ └───────────────────────────────────────────────────────────────────────────┘ And, finally, change getConfigOptions() function, adding a 'case' inside the 'switch(cli_opts)' block, like this: ┌───────────────────────────────────────────────────────────────────────────┐ │ case OPTION_SCTP_TAG: co.sctp.tag = atoi(optarg): break; │ └───────────────────────────────────────────────────────────────────────────┘ ** STEP 4 Create a routine showing the usage for SCTP protocol options and put it on sctp_help.c at 'src/help/' directory: ┌─────────────────────────────────────────────────────────────────────────────────────────────────┐ │ void sctp_help(void) │ │ { │ │ puts("SCTP Options:\n" │ │ " --sctp-tag NUM SCTP tag number (default RANDOM)\n"); │ │ } │ └─────────────────────────────────────────────────────────────────────────────────────────────────┘ To keep the standard, the first line starts with a description of the protocol followed by "Options:". The following lines are formated as (printf style): " --%-23s %-32s (default: %s)\n" Where the first string (max 23 chars) is the option. The second string (32 chars max) is a small description and the last string is a numeric value or "RANDOM", depending of what you did in config_options 'co' and your module. After creating the sctp_help() functiom, put a call on the usage routine at 'src/usage.c': ┌───────────────────────────────────────────────────────────────────────────────┐ │ ... │ │ rsvp_help(); │ │ ipsec_help(); │ │ eigrp_help(); │ │ ospf_help(); │ │ sctp_help(); /* Added sctp help */ │ └───────────────────────────────────────────────────────────────────────────────┘ ** STEP 5 (FINAL) Modify the Makefile adding the object filename (sctp.o) file location on OBJS var: ┌────────────────────────────────────────────────────────────────────────────────┐ │ ... │ │ $(OBJ_DIR)/modules/igmpv1.o \ │ │ $(OBJ_DIR)/modules/icmp.o \ │ │ $(OBJ_DIR)/modules/sctp.o \ <-- here! │ │ $(OBJ_DIR)/common.o \ │ │ ... │ └────────────────────────────────────────────────────────────────────────────────┘ And test everything trying to compile the project: $ make Don't forget to compile in DEBUG mode and test everything with your favorite debugger: $ DEBUG=1 make $ sudo gdb release/t50 Good luck!
