Discussion about rules normally takes place on snort-sigs, so you guys probably aren't following the discussion on this rule over there. In short, the current revision of the rule is 3 and it is now in deleted.rules. The rule will appear in the deleted.rules for registered users when they can download the rules released on October 5th. In the meantime, might as well move it there yourselves.

I haven't had time to review the rule itself to see if I can figure out what the issue is exactly - I can supply data if needed.Also - does anyone have a script that could extract the full details ofthe even from the Snorby database? I have a hard time providing data using the web-based export methods, as it doesn't contain all the information. Thanks!I'll second the large amounts of "false positives" on that signature. I came in today to several hundred alerts for 17246. The signature src addresses are fairly random (banking site, diet site, several ad servers, etc) and all are from web traffic (tcp/80).
