By contrast, the GNU General Public 13 | License is intended to guarantee your freedom to share and change free 14 | software--to make sure the software is free for all its users. This 15 | General Public License applies to most of the Free Software 16 | Foundation's software and to any other program whose authors commit to 17 | using it. (Some other Free Software Foundation software is covered by 18 | the GNU Library General Public License instead.) You can apply it to 19 | your programs, too. 20 | 21 | When we speak of free software, we are referring to freedom, not 22 | price. Our General Public Licenses are designed to make sure that you 23 | have the freedom to distribute copies of free software (and charge for 24 | this service if you wish), that you receive source code or can get it 25 | if you want it, that you can change the software or use pieces of it 26 | in new free programs; and that you know you can do these things. 27 | 28 | To protect your rights, we need to make restrictions that forbid 29 | anyone to deny you these rights or to ask you to surrender the rights. 30 | These restrictions translate to certain responsibilities for you if you 31 | distribute copies of the software, or if you modify it. 32 | 33 | For example, if you distribute copies of such a program, whether 34 | gratis or for a fee, you must give the recipients all the rights that 35 | you have. You must make sure that they, too, receive or can get the 36 | source code. And you must show them these terms so they know their 37 | rights. 38 | 39 | We protect your rights with two steps: (1) copyright the software, and 40 | (2) offer you this license which gives you legal permission to copy, 41 | distribute and/or modify the software. 42 | 43 | Also, for each author's protection and ours, we want to make certain 44 | that everyone understands that there is no warranty for this free 45 | software. If the software is modified by someone else and passed on, we 46 | want its recipients to know that what they have is not the original, so 47 | that any problems introduced by others will not reflect on the original 48 | authors' reputations. 49 | 50 | Finally, any free program is threatened constantly by software 51 | patents. We wish to avoid the danger that redistributors of a free 52 | program will individually obtain patent licenses, in effect making the 53 | program proprietary. To prevent this, we have made it clear that any 54 | patent must be licensed for everyone's free use or not licensed at all. 55 | 56 | The precise terms and conditions for copying, distribution and 57 | modification follow. 58 | 59 | GNU GENERAL PUBLIC LICENSE 60 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61 | 62 | 0. This License applies to any program or other work which contains 63 | a notice placed by the copyright holder saying it may be distributed 64 | under the terms of this General Public License. The "Program", below, 65 | refers to any such program or work, and a "work based on the Program" 66 | means either the Program or any derivative work under copyright law: 67 | that is to say, a work containing the Program or a portion of it, 68 | either verbatim or with modifications and/or translated into another 69 | language. (Hereinafter, translation is included without limitation in 70 | the term "modification".) Each licensee is addressed as "you". 71 | 72 | Activities other than copying, distribution and modification are not 73 | covered by this License; they are outside its scope. The act of 74 | running the Program is not restricted, and the output from the Program 75 | is covered only if its contents constitute a work based on the 76 | Program (independent of having been made by running the Program). 77 | Whether that is true depends on what the Program does. 78 | 79 | 1. You may copy and distribute verbatim copies of the Program's 80 | source code as you receive it, in any medium, provided that you 81 | conspicuously and appropriately publish on each copy an appropriate 82 | copyright notice and disclaimer of warranty; keep intact all the 83 | notices that refer to this License and to the absence of any warranty; 84 | and give any other recipients of the Program a copy of this License 85 | along with the Program. 86 | 87 | You may charge a fee for the physical act of transferring a copy, and 88 | you may at your option offer warranty protection in exchange for a fee. 89 | 90 | 2. You may modify your copy or copies of the Program or any portion 91 | of it, thus forming a work based on the Program, and copy and 92 | distribute such modifications or work under the terms of Section 1 93 | above, provided that you also meet all of these conditions: 94 | 95 | a) You must cause the modified files to carry prominent notices 96 | stating that you changed the files and the date of any change. 97 | 98 | b) You must cause any work that you distribute or publish, that in 99 | whole or in part contains or is derived from the Program or any 100 | part thereof, to be licensed as a whole at no charge to all third 101 | parties under the terms of this License. 102 | 103 | c) If the modified program normally reads commands interactively 104 | when run, you must cause it, when started running for such 105 | interactive use in the most ordinary way, to print or display an 106 | announcement including an appropriate copyright notice and a 107 | notice that there is no warranty (or else, saying that you provide 108 | a warranty) and that users may redistribute the program under 109 | these conditions, and telling the user how to view a copy of this 110 | License. (Exception: if the Program itself is interactive but 111 | does not normally print such an announcement, your work based on 112 | the Program is not required to print an announcement.) 113 | 114 | These requirements apply to the modified work as a whole. If 115 | identifiable sections of that work are not derived from the Program, 116 | and can be reasonably considered independent and separate works in 117 | themselves, then this License, and its terms, do not apply to those 118 | sections when you distribute them as separate works. But when you 119 | distribute the same sections as part of a whole which is a work based 120 | on the Program, the distribution of the whole must be on the terms of 121 | this License, whose permissions for other licensees extend to the 122 | entire whole, and thus to each and every part regardless of who wrote it. 123 | 124 | Thus, it is not the intent of this section to claim rights or contest 125 | your rights to work written entirely by you; rather, the intent is to 126 | exercise the right to control the distribution of derivative or 127 | collective works based on the Program. 128 | 129 | In addition, mere aggregation of another work not based on the Program 130 | with the Program (or with a work based on the Program) on a volume of 131 | a storage or distribution medium does not bring the other work under 132 | the scope of this License. 133 | 134 | 3. You may copy and distribute the Program (or a work based on it, 135 | under Section 2) in object code or executable form under the terms of 136 | Sections 1 and 2 above provided that you also do one of the following: 137 | 138 | a) Accompany it with the complete corresponding machine-readable 139 | source code, which must be distributed under the terms of Sections 140 | 1 and 2 above on a medium customarily used for software interchange; or, 141 | 142 | b) Accompany it with a written offer, valid for at least three 143 | years, to give any third party, for a charge no more than your 144 | cost of physically performing source distribution, a complete 145 | machine-readable copy of the corresponding source code, to be 146 | distributed under the terms of Sections 1 and 2 above on a medium 147 | customarily used for software interchange; or, 148 | 149 | c) Accompany it with the information you received as to the offer 150 | to distribute corresponding source code. (This alternative is 151 | allowed only for noncommercial distribution and only if you 152 | received the program in object code or executable form with such 153 | an offer, in accord with Subsection b above.) 154 | 155 | The source code for a work means the preferred form of the work for 156 | making modifications to it. For an executable work, complete source 157 | code means all the source code for all modules it contains, plus any 158 | associated interface definition files, plus the scripts used to 159 | control compilation and installation of the executable. However, as a 160 | special exception, the source code distributed need not include 161 | anything that is normally distributed (in either source or binary 162 | form) with the major components (compiler, kernel, and so on) of the 163 | operating system on which the executable runs, unless that component 164 | itself accompanies the executable. 165 | 166 | If distribution of executable or object code is made by offering 167 | access to copy from a designated place, then offering equivalent 168 | access to copy the source code from the same place counts as 169 | distribution of the source code, even though third parties are not 170 | compelled to copy the source along with the object code. 171 | 172 | 4. You may not copy, modify, sublicense, or distribute the Program 173 | except as expressly provided under this License. Any attempt 174 | otherwise to copy, modify, sublicense or distribute the Program is 175 | void, and will automatically terminate your rights under this License. 176 | However, parties who have received copies, or rights, from you under 177 | this License will not have their licenses terminated so long as such 178 | parties remain in full compliance. 179 | 180 | 5. You are not required to accept this License, since you have not 181 | signed it. However, nothing else grants you permission to modify or 182 | distribute the Program or its derivative works. These actions are 183 | prohibited by law if you do not accept this License. Therefore, by 184 | modifying or distributing the Program (or any work based on the 185 | Program), you indicate your acceptance of this License to do so, and 186 | all its terms and conditions for copying, distributing or modifying 187 | the Program or works based on it. 188 | 189 | 6. Each time you redistribute the Program (or any work based on the 190 | Program), the recipient automatically receives a license from the 191 | original licensor to copy, distribute or modify the Program subject to 192 | these terms and conditions. You may not impose any further 193 | restrictions on the recipients' exercise of the rights granted herein. 194 | You are not responsible for enforcing compliance by third parties to 195 | this License. 196 | 197 | 7. If, as a consequence of a court judgment or allegation of patent 198 | infringement or for any other reason (not limited to patent issues), 199 | conditions are imposed on you (whether by court order, agreement or 200 | otherwise) that contradict the conditions of this License, they do not 201 | excuse you from the conditions of this License. If you cannot 202 | distribute so as to satisfy simultaneously your obligations under this 203 | License and any other pertinent obligations, then as a consequence you 204 | may not distribute the Program at all. For example, if a patent 205 | license would not permit royalty-free redistribution of the Program by 206 | all those who receive copies directly or indirectly through you, then 207 | the only way you could satisfy both it and this License would be to 208 | refrain entirely from distribution of the Program. 209 | 210 | If any portion of this section is held invalid or unenforceable under 211 | any particular circumstance, the balance of the section is intended to 212 | apply and the section as a whole is intended to apply in other 213 | circumstances. 214 | 215 | It is not the purpose of this section to induce you to infringe any 216 | patents or other property right claims or to contest validity of any 217 | such claims; this section has the sole purpose of protecting the 218 | integrity of the free software distribution system, which is 219 | implemented by public license practices. Many people have made 220 | generous contributions to the wide range of software distributed 221 | through that system in reliance on consistent application of that 222 | system; it is up to the author/donor to decide if he or she is willing 223 | to distribute software through any other system and a licensee cannot 224 | impose that choice. 225 | 226 | This section is intended to make thoroughly clear what is believed to 227 | be a consequence of the rest of this License. 228 | 229 | 8. If the distribution and/or use of the Program is restricted in 230 | certain countries either by patents or by copyrighted interfaces, the 231 | original copyright holder who places the Program under this License 232 | may add an explicit geographical distribution limitation excluding 233 | those countries, so that distribution is permitted only in or among 234 | countries not thus excluded. In such case, this License incorporates 235 | the limitation as if written in the body of this License. 236 | 237 | 9. The Free Software Foundation may publish revised and/or new versions 238 | of the General Public License from time to time. Such new versions will 239 | be similar in spirit to the present version, but may differ in detail to 240 | address new problems or concerns. 241 | 242 | Each version is given a distinguishing version number. If the Program 243 | specifies a version number of this License which applies to it and "any 244 | later version", you have the option of following the terms and conditions 245 | either of that version or of any later version published by the Free 246 | Software Foundation. If the Program does not specify a version number of 247 | this License, you may choose any version ever published by the Free Software 248 | Foundation. 249 | 250 | 10. If you wish to incorporate parts of the Program into other free 251 | programs whose distribution conditions are different, write to the author 252 | to ask for permission. For software which is copyrighted by the Free 253 | Software Foundation, write to the Free Software Foundation; we sometimes 254 | make exceptions for this. Our decision will be guided by the two goals 255 | of preserving the free status of all derivatives of our free software and 256 | of promoting the sharing and reuse of software generally. 257 | 258 | NO WARRANTY 259 | 260 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268 | REPAIR OR CORRECTION. 269 | 270 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 271 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 272 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 273 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 274 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 275 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 276 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 277 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 278 | POSSIBILITY OF SUCH DAMAGES. 279 | 280 | END OF TERMS AND CONDITIONS 281 | 282 | How to Apply These Terms to Your New Programs 283 | 284 | If you develop a new program, and you want it to be of the greatest 285 | possible use to the public, the best way to achieve this is to make it 286 | free software which everyone can redistribute and change under these terms. 287 | 288 | To do so, attach the following notices to the program. It is safest 289 | to attach them to the start of each source file to most effectively 290 | convey the exclusion of warranty; and each file should have at least 291 | the "copyright" line and a pointer to where the full notice is found. 292 | 293 | 294 | Copyright (C) 295 | 296 | This program is free software; you can redistribute it and/or modify 297 | it under the terms of the GNU General Public License as published by 298 | the Free Software Foundation; either version 2 of the License, or 299 | (at your option) any later version. 300 | 301 | This program is distributed in the hope that it will be useful, 302 | but WITHOUT ANY WARRANTY; without even the implied warranty of 303 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 304 | GNU General Public License for more details. 305 | 306 | You should have received a copy of the GNU General Public License 307 | along with this program; if not, write to the Free Software 308 | Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 309 | 310 | 311 | Also add information on how to contact you by electronic and paper mail. 312 | 313 | If the program is interactive, make it output a short notice like this 314 | when it starts in an interactive mode: 315 | 316 | Gnomovision version 69, Copyright (C) year name of author 317 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 318 | This is free software, and you are welcome to redistribute it 319 | under certain conditions; type `show c' for details. 320 | 321 | The hypothetical commands `show w' and `show c' should show the appropriate 322 | parts of the General Public License. Of course, the commands you use may 323 | be called something other than `show w' and `show c'; they could even be 324 | mouse-clicks or menu items--whatever suits your program. 325 | 326 | You should also get your employer (if you work as a programmer) or your 327 | school, if any, to sign a "copyright disclaimer" for the program, if 328 | necessary. Here is a sample; alter the names: 329 | 330 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program 331 | `Gnomovision' (which makes passes at compilers) written by James Hacker. 332 | 333 | , 1 April 1989 334 | Ty Coon, President of Vice 335 | 336 | This General Public License does not permit incorporating your program into 337 | proprietary programs. If your program is a subroutine library, you may 338 | consider it more useful to permit linking proprietary applications with the 339 | library. If this is what you want to do, use the GNU Library General 340 | Public License instead of this License. 341 | -------------------------------------------------------------------------------- /ChangeLog: -------------------------------------------------------------------------------- 1 | Version 1.5beta7 (2006-03-28) 2 | 3 | Added check to ensure pcap_fd is within the range of select(2) to 4 | avoid any potential FD_SET overflows, by Shaun Colley 5 | 6 | Rebuilt autoconf files with a more recent version of autoconf from a 7 | Debian Sarge system, to resolve Debian Bug#333827. 8 | 9 | Updated the man page and examples.txt files to document the new --dnat 10 | detection features. 11 | 12 | Updated the (unofficial) debian/control file to build-depend on 13 | libnet1-dev rather than libnet0-dev. 14 | 15 | Version 1.5beta6 (2005-01-03) 16 | 17 | New --dnat, --no-dnat (default), and --no-dnat-strict command line 18 | arguments. --dnat enabled Destination NAT detection, which works by 19 | comparing the quoted IP address in an ICMP payload with the 20 | destination a probe packet was addressed to. 21 | 22 | Numeric IP address in parenthesis is now only displayed if the content 23 | in the parenthesis is different than the non-parenthesized content, 24 | making the output less busy. 25 | 26 | The SYN ISN (Initial Sequence Number) now set to a random 32bit value; 27 | previously had always been zero. 28 | 29 | Added missing htons() call around the arguments to getservbyport(), 30 | which resulted in the destination port service name not being correctly 31 | reported on some architectures, by Dmitry Karasik 32 | 33 | Improved the configure.ac so that it is less likely to link against 34 | unnecessary libraries by "Dmitry V. Levin" 35 | 36 | --no-select is now the default under NetBSD, based on a report and data 37 | collected by Ed Ravin . 38 | 39 | Split the tcptraceroute.c file into main.c, datalink.c, probe.c, 40 | capture.c, util.c, and a number of include files, which should make 41 | things much more manageable. 42 | 43 | Version 1.5beta5 (2003-07-02) 44 | 45 | Now functions properly with libpcap when using an interface without a 46 | valid IPv4 addresss. Reported by Kris Shannon 47 | in Debian Bug#183456. 48 | 49 | Improved autoconf handling of the --with-libpcap= command line argument, 50 | by Richard van den Berg . 51 | 52 | Moved the tcptraceroute man page to section 1 from section 8 now that 53 | tcptraceroute is installed in /usr/bin by default, as suggested by 54 | James Ralston . 55 | 56 | Added a missing call to pcap_freecode() to free up memory utilized 57 | by the bpf_program struct, after applying it with pcap_setfilter(). 58 | 59 | Should now deal better (and skip over) unconfigured interface under 60 | NetBSD. 61 | 62 | Version 1.5beta4 (2003-06-29) 63 | 64 | A call to seteuid() has been replaced with a call to setuid() to fully 65 | drop root privileges. As there are currently no known exploitable 66 | portions of tcptraceroute, older versions are still believed to be 67 | safe even without fully dropping privileges, however users are still 68 | encouraged to upgrade to provide a measure of containment in the event 69 | that an exploitable flaw is discovered in the future. Reported by Matt 70 | Zimmerman , and published in Debian Security Advisory 71 | DSA 330-1. 72 | 73 | AC_FUNC_REALLOC was commented out of configure.ac, which was failing on 74 | HP/UX badly systems. The xrealloc() function in tcptraceroute already 75 | works around the realloc(0,0) case that AC_FUNC_REALLOC is attempting 76 | to prevent against, anyway. Reported by Petter Reinholdtsen 77 | . 78 | 79 | Version 1.5beta3 (2003-06-01) 80 | 81 | Added some additional AC_CHECK_LIB lines to the configure.ac file, 82 | required for Solaris systems, by Petter Reinholdtsen . 83 | 84 | Fixed a number of type warnings under non-gcc compilers by adding a few 85 | casts; reported by Petter Reinholdtsen . 86 | 87 | Version 1.5beta2 (2003-05-25) 88 | 89 | Added an autoconf check to detect MacOS X systems by looking to see if 90 | __APPLE__ and __MACH__ are defined. Also added an autoconf configure 91 | command line argument --enable-noselect-default to control the default 92 | behavior of the tcptraceroute --noselect command line argument, and 93 | enabled it by default on MacOS X systems if not otherwise specified. 94 | 95 | Version 1.5beta1 (2003-05-24) 96 | 97 | Most substantially, support for both autoconf and libnet-1.1.x 98 | has been added, based on patches from (in alphabetical order): 99 | 100 | jbash@velvet.com 101 | Jon Allen Boone 102 | James Ralston 103 | Darren Tucker 104 | Matt Weidner 105 | 106 | Added linklayer support for PPPoE interfaces, by Darren Tucker 107 | . 108 | 109 | Improved the round trip time calculations, by Amgad Zeitoun 110 | . 111 | 112 | Removed a number of multi-line strings, which apparently causes 113 | trouble for some compilers, based on patches from: 114 | 115 | jbash@velvet.com 116 | Richard van den Berg 117 | Petter Reinholdtsen 118 | 119 | Version 1.4 (2002-07-30) 120 | 121 | Added linklayer support for Linux ISDN Sync-PPP interfaces, 122 | by Dr. Peter Bieringer . 123 | 124 | Adds support back for DLT_RAW interfaces, which was inadvertently 125 | removed sometime between 1.2 and 1.3beta1, and as a result caused 126 | tcptraceroute to fail over PPP interfaces. Reported in Debian 127 | Bug#154793 by David Harris . 128 | 129 | Version 1.3 (2002-05-19) 130 | 131 | Now detects (and ignores) IP packets with IP options. 132 | 133 | Packets are now properly aligned by allocating new space and 134 | copying the packet data there before casting packet header 135 | structs against them. 136 | 137 | New, undocumented --no-select command line argument added to never 138 | call select(), which fails to indicate that a BPF socket is ready 139 | for reading on some BSD systems. 140 | 141 | Now sets a non-zero exit code if the destination was not reached, 142 | as suggested by Arndt Schoenewald 143 | 144 | Fixes an off-by-one error in getinterfaces(), discovered by 145 | Kit Knox . 146 | 147 | probe() and capture() now use a new proberecord structure which 148 | contains information about each probe in a modularized way. 149 | 150 | Added a new command line argument, --track-port, which causes each 151 | probe to have a unique source port so that something other than the 152 | IP ID can be used to track it, and also a corresponding --track-id 153 | argument to specify the old behavior of tracking IP ID's. If a 154 | source port is specified with -p, --track-id is implied. The 155 | compile-time default on Solaris is --track-port, enabling 156 | tcptraceroute to work out-of-the-box, and --track-id on all other 157 | platforms. 158 | 159 | probe() now calls allocateid() to generate an IP ID, which 160 | caches the last ALLOCATEID_CACHE_SIZE allocations to prevent 161 | against duplicates. 162 | 163 | Display "!" instead of "!?" for unknown ICMP codes, as 164 | suggested by Kevin McAllister 165 | 166 | Attempts to find virtual addresses under OpenBSD, based on a 167 | patch by Scott Gifford 168 | 169 | Moves the datalinkoffset and datalinkname information into a 170 | single data structure, which is much more logical, and less 171 | prone to error. 172 | 173 | Improved command line argument handling a good deal, based 174 | on suggestions by Scott Fenton . First, 175 | a pass through is made to process and shift out long command 176 | line arguments, then the remaining command line is passed to 177 | getopt(). 178 | 179 | It is now possible to traceroute to yourself, by switching the 180 | device to the loopback interface if the destination matches the 181 | address of a local interface. Additionally, as learned by 182 | looking through the nmap source, we now never set a libpcap 183 | filter on the loopback interface to avoid apparent libpcap bugs 184 | which previously made it impossible to traceroute to 127.0.0.1 185 | 186 | Added -S and -A command line arguments to control the SYN 187 | and ACK flags in outgoing packets. By using -A, it is now 188 | possible to traceroute through stateless firewalls which 189 | permit hosts behind the firewalls to establish outgoing TCP 190 | connections. In the absence of either -A or -S, -S is set. 191 | 192 | Added -N command line argument which takes the place of the 193 | previous RESOLVE_RFC1918 #define. 194 | 195 | Now displays if the remote host is ECN capable when using -E 196 | 197 | Version 1.2 (2001-07-31) 198 | 199 | Contains large portions of code and ideas contributed by 200 | Scott Gifford 201 | 202 | Attempt to determine what outgoing interface to use based on 203 | the destination address and the local system's interface list. 204 | Could still use a good deal of work on BSD systems, though, 205 | especially when it comes to virtual addresses which reside on 206 | subnets different than the primary address. 207 | 208 | The timeout code has been reworked significantly, and should 209 | now be much more reliable. 210 | 211 | Added -E command line argument to send ECN (RFC2481) packets. 212 | Requested by Christophe Barb and 213 | Jim Penny 214 | 215 | Added -l command line argument to set the total packet length, 216 | including IP header. 217 | 218 | Added support for sending more than one probe to each hop, and 219 | the -q command line option to specify the number of probes. 220 | 221 | Added -F command line argument to set the IP_DF bit. 222 | 223 | Added -t command line argument to set the IP TOS. 224 | 225 | Now properly checks the length of the packets returned by libpcap 226 | before blindly assuming that the entire header structure we happen 227 | to be looking for is there. This could have been very ugly had the 228 | snaplen not been set so conservatively. 229 | 230 | Print banner information to stderr, not stdout, to be compatible with 231 | traceroute(8). Reported by Scott Fenton 232 | 233 | Fixed an endian bug reported by Zoran Dzelajlija , 234 | which prevented users from specifying the destination port number by 235 | name. 236 | 237 | Version 1.1 (2001-06-30) 238 | 239 | Now drops root privileges after sockets have been opened. 240 | 241 | Must now be root to use -s or -p, making it now safe to to install 242 | tcptraceroute suid root, without fear that users can generate arbitrary 243 | SYN packets. 244 | 245 | Version 1.0 (2001-04-10) 246 | 247 | Initial Release. 248 | 249 | # vim:set ts=4 sw=4 tw=75 ai syntax=off: 250 | -------------------------------------------------------------------------------- /INSTALL: -------------------------------------------------------------------------------- 1 | As of release 1.5beta1, tcptraceroute now uses GNU autoconf to ease the 2 | task of installation and to provide better portability. As with all 3 | programs utilizing autoconf, the simplest way to compile the package is 4 | (quoting from the default INSTALL documentation that ships with 5 | autoconf): 6 | 7 | 1. `cd' to the directory containing the package's source code and type 8 | `./configure' to configure the package for your system. If you're 9 | using `csh' on an old version of System V, you might need to type 10 | `sh ./configure' instead to prevent `csh' from trying to execute 11 | `configure' itself. 12 | 13 | Running `configure' takes awhile. While running, it prints some 14 | messages telling which features it is checking for. 15 | 16 | 2. Type `make' to compile the package. 17 | 18 | 3. Type `make install' to install the programs and any data files and 19 | documentation. 20 | 21 | 4. You can remove the program binaries and object files from the 22 | source code directory by typing `make clean'. To also remove the 23 | files that `configure' created (so you can compile the package for 24 | a different kind of computer), type `make distclean'. 25 | 26 | The configure scripts supports a number of command line options. The 27 | ones you're most likely to use are: 28 | 29 | --prefix=PREFIX install architecture-independent files in 30 | PREFIX [/usr/local] 31 | --with-libpcap=DIR use libpcap in DIR 32 | --with-libnet=DIR use libnet in DIR 33 | --enable-noselect-default 34 | default to not using select(2) 35 | --enable-track-default=PORT|ID 36 | default to tracking probes by PORT or ID 37 | --enable-default-port=N default destination port 38 | --enable-static compile staticly, if using gcc 39 | 40 | -mct, Sun May 25 11:16:48 EDT 2003 41 | -------------------------------------------------------------------------------- /Makefile.am: -------------------------------------------------------------------------------- 1 | bin_PROGRAMS = tcptraceroute 2 | tcptraceroute_SOURCES = main.c datalink.c util.c probe.c capture.c 3 | man_MANS = tcptraceroute.1 4 | 5 | docdir = $(datadir)/doc/tcptraceroute 6 | doc_DATA = AUTHORS COPYING ChangeLog NEWS README \ 7 | examples.txt tcptraceroute.1.html tcptraceroute.lsm 8 | 9 | EXTRA_DIST = $(doc_DATA) $(man_MANS) VERSION debian 10 | 11 | # AM_CFLAGS = @AM_CFLAGS@ 12 | 13 | -------------------------------------------------------------------------------- /Makefile.in: -------------------------------------------------------------------------------- 1 | # Makefile.in generated automatically by automake 1.4-p6 from Makefile.am 2 | 3 | # Copyright (C) 1994, 1995-8, 1999, 2001 Free Software Foundation, Inc. 4 | # This Makefile.in is free software;

However, in many cases, these firewalls will permit 53 | inbound TCP packets to specific ports that hosts sitting behind the 54 | firewall are listening for connections on.

DESCRIPTION

78 | 79 | tcptraceroute 80 | 81 | is a traceroute implementation using TCP packets. 82 | 83 | The more traditional 84 | traceroute(8) 85 | 86 | sends out either UDP or ICMP ECHO packets with a TTL of one, and increments 87 | the TTL until the destination has been reached. By printing the gateways that 88 | generate ICMP time exceeded messages along the way, it is able to determine the 89 | path packets are taking to reach the destination. 90 |

91 | 92 | The problem is that with the widespread use of firewalls on the modern 93 | Internet, many of the packets that 94 | traceroute(8) 95 | sends out end up being filtered, making it impossible to completely trace the 96 | path to the destination. However, in many cases, these firewalls will permit 97 | inbound TCP packets to specific ports that hosts sitting behind the 98 | firewall are listening for connections on. By sending out TCP SYN packets 99 | instead of UDP or ICMP ECHO packets, 100 | tcptraceroute 101 | is able to bypass the most common firewall filters. 102 |

103 | 104 | It is worth noting that 105 | tcptraceroute 106 | 107 | never completely establishes a TCP connection with the destination host. 108 | If the host is not listening for incoming connections, it will respond with 109 | an RST indicating that the port is closed. If the host instead responds 110 | with a SYN|ACK, the port is known to be open, and an RST is sent by the 111 | kernel 112 | tcptraceroute 113 | 114 | is running on to tear down the connection without completing 115 | three-way handshake. This is the same half-open scanning technique 116 | that 117 | nmap(1) 118 | 119 | uses when passed the 120 | -sS 121 | 122 | flag. 123 |   124 |

OPTIONS

125 | 126 |
127 |
-n
128 | 129 | 130 | Display numeric output, rather than doing a reverse DNS lookup for each hop. 131 | By default, reverse lookups are never attempted on RFC1918 address space, 132 | regardless of the -n flag. 133 |
-N
134 | 135 | 136 | Perform a reverse DNS lookup for each hop, including RFC1918 addresses. 137 |
-f
138 | 139 | 140 | Set the initial TTL used in the first outgoing packet. The default is 1. 141 |
-m
142 | 143 | 144 | Set the maximum TTL used in outgoing packets. The default is 30. 145 |
-p
146 | 147 | 148 | Use the specified local TCP port in outgoing packets. The default is to 149 | obtain a free port from the kernel using 150 | >bind(2). 151 | 152 | Unlike with traditional 153 | traceroute(8), 154 | 155 | this number will not increase with each hop. 156 |
-s
157 | 158 | 159 | Set the source address for outgoing packets. See also the -i flag. 160 |
-i
161 | 162 | 163 | Use the specified interface for outgoing packets. 164 |
-q
165 | 166 | 167 | Set the number of probes to be sent to each hop. The default is 3. 168 |
-w
169 | 170 | 171 | Set the timeout, in seconds, to wait for a response for each probe. The 172 | default is 3. 173 |
-S
174 | 175 | 176 | Set the TCP SYN flag in outgoing packets. This is the default, if neither 177 | -S or -A is specified. 178 |
-A
179 | 180 | 181 | 182 | 183 | Set the TCP ACK flag in outgoing packets. By doing so, it is possible to 184 | trace through stateless firewalls which permit outgoing TCP connections. 185 |
-E
186 | 187 | 188 | Send ECN SYN packets, as described in RFC2481. 189 |
-t
190 | 191 | 192 | Set the IP TOS (type of service) to be used in outgoing packets. The 193 | default is not to set any TOS. 194 |
-F
195 | 196 | 197 | Set the IP "don't fragment" bit in outgoing packets. 198 |
-l
199 | 200 | 201 | Set the total packet length to be used in outgoing packets. If the length 202 | is greater than the minimum size required to assemble the necessary probe 203 | packet headers, this value is automatically increased. 204 |
-d
205 | 206 | Enable debugging, which may or may not be useful. 207 |

208 | 209 |

--dnat
210 | 211 |
212 | Enable DNAT detection, and display messages when DNAT transitions are 213 | observed. DNAT detection is based on the fact that some NAT devices, 214 | such as some Linux 2.4 kernels, do not correctly rewrite the IP address 215 | of the IP packets quoted in ICMP time-exceeded messages 216 | tcptraceroute solicits, revealing the destination IP address an outbound 217 | probe packet was NATed to. NAT devices which correctly rewrite the IP 218 | address quoted by ICMP messages, such as some Linux 2.6 kernels, will 219 | not be detected. For some target hosts, it may be necessary to use 220 | --dnat in conjunction with --track-port. See the examples.txt file for 221 | examples. 222 |

223 | 224 |

--no-dnat
225 |
226 | Enable DNAT detection for the purposes of correctly identifying ICMP 227 | time-exceeded messages that match up with outbound probe packets, but 228 | do not display messages when a DNAT transition is observed. This is 229 | the default behavior. 230 |

231 | 232 |

--no-dnat-strict
233 |
234 | Do not perform any DNAT detection whatsoever. No attempt will be made 235 | match up ICMP time-exceeded messages with outbound probe packets, and 236 | when tracerouting through a NAT device which does not rewrite the IP 237 | addresses of the IP packets quoted in ICMP time-exceeded messages, some 238 | hops along the path may appear to be unresponsive. This option should 239 | not be needed in the vast majority of cases, but may be utilized if 240 | it is suspected that the DNAT detection code is misidentifying ICMP 241 | time-exceeded messages. 242 |

BUGS

273 | 274 | No error checking is performed on the source address specified by the -s 275 | flag, and it is therefore possible for 276 | tcptraceroute 277 | 278 | to send out TCP SYN packets for which it has no chance of seeing a response 279 | to. 280 |   281 |
