Re: Signature Message, PP, and sid-msg.map

Did this have to do with the post two weeks ago about some of the newer
preprocessor sid:gids not being added?

It does generate the sid-msg.map file... Can you list the aids that were
not included.... There was recently a bug filed and fixed that dealt with
certain rules not being included (fixed in SVN)

This may have been discussed before but I did not find a definitive
answer or an optimal solution. I use PulledPork to generate VRT rules
(snort.rules) and the sid-msg.map, etc. The process completes successfully.
I run Snort and alerts start showing up, however, I do not get signature
messages (sig_name in the DB table) for some rules in there. I only get
something like, for examples: "Snort Alert [1:255:19]". This happens to a
considerable amount of rules.

Since the rules are firing and they exist in the snort.rules file, this
means that they have been processed by PulledPork, however, they do not
have respective entries in the sid-msg.map file. I updated those manually,
both in the database and the sid-msg.map file and now are showing up fine.
As snort continues to run, I get new alerts with no signature message and
do the updates again and so on.

My question(s) is, does PulledPork generate the sid-msg.map file
dynamically once it is run? If so, why some rules do not get mapped into
the file?

I have read in a group discussion (can't remember where!) that this is
related to the reorganization of the rules and should go away once
everything stabilizes, please correct if I am wrong.

This can take an effort to get rules updated to show up properly every
time the rules are updated and PulledPork is run.

Any help would be appreciated. Thanks in advance.
