Re: v2.8.4 incorrect logging to MySQL

All fair points and I couldn't agree more. I know I've not done a good
job documenting the perl module. Creating a dedicated unified(2)
processor would be preferable to me as well.

I'd throw in a vote for this too, but out of curiosity... why unified
over unified2?

Either way, before you could do that there would have to be an
"official" tool to read the binary file and output it to other
formats. By official I mean something supported, documented (right on
the snort web site), and, maintained so we know it will be there
tomorrow and doesn't fade off into nothing like barnyard.

Right now there are 3 options:

Barnyard: http://www.snort.org/dl/barnyard/
- Works with unified but not unified2
- abandon ware
- DB connection issues

Barnyard2: http://www.securixlive.com/barnyard2/index.php
- Works with unified and unified2
- I have seen the same DB connection issues as with barnyard

SnortUnified.pm: http://code.google.com/p/snort-unified-perl/
- Works but not very well documented (no disrespect meant Jason)
- Not sure about the DB connection issue. I have tried to use this a
couple of times, I'm not the best with perl so the lack of doc's left
me scratching my head.

I wouldn't call any of these official. Recommended, but not official.

Seconded.

Here is my vote to remove all output methods from the engine except
unified, to remove the code complexity. People are much better off
having two dedicated processes achieving a common goal than they are
with the code complexity and issues in the one code base.

Subject: RE: [Snort-users] v2.8.4 incorrect logging to MySQL

We are backing down from v2.8.4 until the new version can successfully
write
to the sensor and signature tables correctly.

Until Soucrefire truly removes writing to the MySQL database and forces
unified logging we see no reason to change at this time.  Yes the new
rule
changes are much wanted, but after reading on the mass issues on the
snort
forums with the new version we are holding off on the update.

Thanks




I have to chime in and second this.  Though Unified might be best, for
smaller shops, my perception is that barnyard is an added layer of
complexity.  I run snort at the house on OS X...pretty much to catch
the
obvious dumb crap coming in from the outside world and to catch if the
kids
machines get something naughty.  Again, larger shops where IDS is
mission
critical should take the extra step, but small ones..eh...I’ve found
that
logging direct to mysql works well enough.  My 0.02 I guess.
