[unisog] Snort woes

The 'tag' directive is used on many of the bleedingsnort.org rules ..

See section 3.7.5 of the Snort users manual :

If you're using the "database" output plugin, all those 'tagged' packets 
all show up under the same Sig_ID and there isn't an effective way (that 
I'm aware of) to get a DB frontend to reassemble them for you. This is, 
in my opinion, more than a 'little' annoying.

If you're using Oinkmaster for rule management, it's a trivial matter to 
setup the config to strip the 'tag, 20, pakets' out of each line (the 
same can be done with simple 'ol sed, perl, awk, etc.).

PS : while we're on the subject, does anyone know of a frontend for the 
snort_db that can graphically reassemble the packets generated under the 
'tag' directive? Or an easy to post-process them into a tcpdump file 
(without using the binary mode)?
