Well I could be wrong of course, but I didn't think the preprocessor rules changed because the preprocessors themselves 
don't change except with an upgrade of the main code base?

Well when i look in the VRT ruleset I see it there, and the last
upgrade to 2.9.3.1 was a while back . but that could be.

Since the file is going to change with the preprocessor rules, I would
have thought it came with the vrt rule file.

And double checking, the snortrules-snapshot-2931.tar.gz does contain
'etc/gen-msg.map'  with today's date (could be from the extraction)

The one from the snort 2.9.3.1 tarball has a date of 4/27/12 and they
do have different sizes and md5sums.

Gen-msg.map is packaged with the snort tarball I think, it doesn't change with VRT updates.  Maybe you didn't copy 
the new one into the right directory when you upgraded?

Subject: [Snort-users] gen-msg.map missing some SIDs for dcerpc2

the latest VRT ruleset has a gen-msg.map that is missing some SIDs; at least some from the dcerpc2 processor.  We 
started getting some alerts for 133.52 and looking at the README.dcerpc2 shows events up to 56 but the gen-msg.map 
only goes up to 133:43 (with 44-47 commented out).

pulledpork only updates the sid-msg.map correct?

Is this something that should be fixed in the vrt ruleset?
