Subject: [Snort-sigs] Pb with rule 2000346
Date: Mon, 06 Sep 2004 16:07:40 +0200 
This rule contain a mistake:

alert tcp $EXTERNAL_NET any -> $HOME_NET !6661:6668 (msg:"BLEEDING-EDGE IRC - Name response on non-std port"; content:"\:"; offset:0; depth:1; content:" 302 "; content:"=+"; content:"@"; dsize:<128; flow:to_client,established; tag:session,300,seconds; classtype:trojan-activity; sid:2000346; rev:3;)

It should be :

alert tcp $EXTERNAL_NET !6661:6668 -> $HOME_NET any (msg:"BLEEDING-EDGE IRC - Name response on non-std port"; content:"\:"; offset:0; depth:1; content:" 302 "; content:"=+"; content:"@"; dsize:<128; flow:to_client,established; tag:session,300,seconds; classtype:trojan-activity; sid:2000346; rev:4;)
