Re: Snort 2.9.0.2 / barnyard2 / base 1.4.5 signature not displayed and is unclassified

[JS <jspudz () yahoo com>]

Kevin thanks for the info. I reviewed my setup and my startup script for 
barnyard2 and its barnyard.conf both point to the gen-msg.map and sid-msg.map 
files in the /etc/snort directory. Those files were updated when I updated with 
the snort 2.9.0.1 ruleset.

This is uber confusing as I have been reading the "README" for stream5 from 
snort 2.9.0.2 and it only lists SID's for stream5 (generatorid 129) that go up 
to number 14. Yet somehow my snort install (version 2.9.0.2) is throwing a SID 
of 15??? 


As far as I can see this event sid (129-15) does not even exist in snort 2.9.0.2 
according to the readme. Any thoughts on this?

You need to include your gen-msg.map file in barnyard.conf. What it means if a 
number and GID is showing in the name in base instead of a proper name is that 
it doesn't have a -msg.map file such as it is missing from sid-msg.map, 
gen-msg.map etc. If you include them to be used then the name will appear. You 
may enounter the same issue if you do not update your sid-msg.map file and 
alerts appear for stuff (if you don't do it by script).
