(Actually, rev and classtype - are also added if missing, unless you edit addsid.pl and tune this.) The - script first looks for the current highest SID (even in inactive rules) - and starts at the next one, unless this value is below MIN_SID (defined - inside addsid.pl). By default, this value is set to 1000001 since this - is the lowest SID assigned for local usage. Handles multi-line rules. -------------------------------------------------------------------------------- - - - -------------------------------------------------------------------------------- -* create-sidmap.pl by Andreas Östling <andreaso@it.su.se> - - A script that parses all active rules in *.rules in all specified - directories and creates a SID map. (Like Snort's regen-sidmap, but this - one handles multi-line rules.) Result goes to standard output which can - be redirected to a sid-msg.map file. -------------------------------------------------------------------------------- - - - -------------------------------------------------------------------------------- -* makesidex.pl, originally by Jerry Applebaum but later rewritten by - Andreas Östling <andreaso@it.su.se> to handle multi-line rules and - multiple rules directories. - - It reads *.rules in all specified directories, looks for all disabled - rules and prints a "disablesid <sid> # <msg>" line for each disabled rule. - The output can be appended to oinkmaster.conf. - Useful to new Oinkmaster users. -------------------------------------------------------------------------------- - - - -------------------------------------------------------------------------------- -* addmsg.pl by Andreas Östling <andreaso@it.su.se>: - - A script that will parse your oinkmaster.conf for - localsid/enablesid/disablesid lines and add their rule message as a #comment. - If your oinkmaster.conf looks like this before addmsg.pl has been run: - - disablesid 286 - disablesid 287 - disablesid 288 - - It will look something like this afterward: - - disablesid 286 # POP3 EXPLOIT x86 bsd overflow - disablesid 287 # POP3 EXPLOIT x86 bsd overflow - disablesid 288 # POP3 EXPLOIT x86 linux overflow - - addmsg.pl will not touch lines that already has a comment in them. - It's not able to handle SID lists when written like this: - disablesid 1,2,3, ... - But it should handle them if written like this: - disablesid \ - 1, \ - 2, \ - 3 - - The new config file will be printed to standard output, so you - probably want to redirect the output to a file, for example: - - ./addmsg.pl oinkmaster.conf rules/ > oinkmaster.conf.new - - If oinkmaster.conf.new looks ok, simply rename it to oinkmaster.conf. - Do NOT redirect to the same file you read from, as this will destroy - that file. -------------------------------------------------------------------------------- diff --git a/config/snort-old/bin/oinkmaster_contrib/addmsg.pl b/config/snort-old/bin/oinkmaster_contrib/addmsg.pl deleted file mode 100644 index e5866d6f..00000000 --- a/config/snort-old/bin/oinkmaster_contrib/addmsg.pl +++ /dev/null @@ -1,299 +0,0 @@ -#!/usr/bin/perl -w - -# $Id: addmsg.pl,v 1.19 2005/12/31 13:42:46 andreas_o Exp $ # - -# Copyright (c) 2004-2006 Andreas Östling <andreaso@it.su.se> -# All rights reserved. -# -# Redistribution and use in source and binary forms, with or -# without modification, are permitted provided that the following -# conditions are met: -# -# 1.
