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

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).

All,

I recently decided to update my IDS(RHEL 5) to use the latest versions of snort, 
barnyard, and base. Previously this was all working fine. I am able to compile 
snort 2.9.0.2, barnyard2, and base 1.4.5 just fine. Everything is working except 
for a few signatures showing up in Base.

They are logging fine to my db, its just that a few of the alerts are showing up 
as "unclassified" and the Signature is displaying as " Snort Alert [129:15:0] ". 
I also see the same events logged for signatures 120:3:0 and 129:16:0. Now I did 
use the snort rules 2.9.0.1 as 2.9.0.2 are not out yet so I'm not sure if that 
is causing a problem or not.. 


I also created a new db, from the create_mysql included in snort 2.9.0.2. I then 
copied over the sid-msg.map, gen-msg.map,  classification.config, unicode.map, 
and reference.config to the /etc/snort directory that were included in 
snort.2.9.0.2 tar file. 


I looked in the gen-msg.map file and I only see it going up to "14" for the 129 
stream5 event. Could this be the problem? Snippit below:

--snippet from gen-msg.map--
129 || 13 || stream5: TCP 4-way handshake detected
129 || 14 || stream5: TCP Timestamp is missing
130 || 1 || dcerpc: Maximum memory usage reached
131 || 1 || dns: Obsolete DNS RData Type
--end snippet--

Have  I missed a step somewhere ? I have never seen this happen in my other 
snort deployments utilizing this same setup.

Thanks,
Joe
