Re: snort 2.8.6.1 / barnyard2 2-1.8 (unified2) problem

You need to update your sid-msg map so that it has all of the meta
information for those SIDs.  You then need to (re)start barnyard2 so that it
inserts the correct information from that point forward.  Of course that
doesn't fix the existing data in the database.  To fix that you will need to
either built a tool that will go back and update the entries with the meta
information or you will want to delete the data and restart barnyard2
telling it to read and insert the old unified data.

 Hi,

Found a problem where the following was returned from the snort.signature

Barnyard2 is suppose to insert signature names like "NETBIOS DCERPC
NCACN-IP-TCP srvsvc NetrPathCanonicalize overflow attempt" into sig_name
of the snort.signature table correct?

So what happened?

Better yet, how do we clean this mess up?

We think Barnyard2 is not at fault, and  the snort sid-msg.map and rules
are the problem.

Are we thinking in the correct direction?

Thanks,
Larry
