Looks like Snorby is not reading from the correct sid-msg.map file.

Subject: [Snort-users] Event mismatch

Hi,

I am observing that an event shown in the snort terminal window appears in the Snorby console with a different 
description. Kindly see below output in the terminal window and refer attachment for same event how it appears in 
Snorby. This event appears in Snorby as “ssh: Gobbles exploit”. SIG & GID is same for both.

Has anybody encountered this issue?

Snort terminal window

I have recently upgraded from Snort version 2.9.5 to 2.9.6.1 (it was compiled from source). After upgrade I have 
replaced the older version of files classification.config, gen.msg.map, reference.config & unicode.map.  Am I missing 
something which is causing this issue?

I use pulledpork version 0.7.0 to update my rules. I update text based rules & so_rules with pulledpork. I use barnyard 
2.1.9 (Build 263) - XFF patch (version 2). I am using mysql  ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) 
using readline 5.1.

Let me know in case any other information regarding my setup is needed.

Thanks.


Regards,
Anshuman
