Yeah, I looked at a few of these sids, definitely was an issue with
improperly handling certain escaped chars (in the pcre for example)..
was fixed and committed a while back.  Please let me know if the issue
persists.

Here is a partial list of the sids, I still have to look at the remaining

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.
