Bug reports should be sent to roesch@clark.net, cc to snort-devel@lists.sourceforge.net (Snort Developers mailing list) Please include the following information with your report: System Architecture (Sparc, x86, etc) Operating System and version (Linux 2.0.22, IRIX 5.3, etc) What rules (if any) you were using What command line switches you were using Any Snort error messages If you get a core file, here is a procedure that would be very helpful for me to debug your problem faster. When it crashes, try the following steps: 1) At the command prompt, type 'gdb snort snort.core'. This will load snort and the core file into the GNU debugger. You may need to give the path to the snort binary file, and your core file might have a different name (like "core" or something). 2) At the (gdb) prompt, type 'bt' (without the quotes). 3) At the (gdb) prompt, type 'quit'. This will return you to your shell. 4) Cut and paste the output from gdb into the email you send me! If the problem could be reproduced, coredump analysis and snort output of 'debug-enabled' build would be appreciated. Hints: To build debugging-enabled snort: make distclean; ./configure --enable-debug; make To debug some particular part of snort functionality: export SNORT_DEBUG= and run snort. See debug.h file for details on debugging levels. (those could be combined, f.e. if you want to see IP and TCP/UDP related info: debuglevel would be: IPdebuglevel + TCPUDPdebuglevel) Thanks! -Marty
