my so_rules complained. they are not in the config. i can see there
is a
reason for them. in the past is not today, and there is no 10.04
so_rules i can see/find/gather.

ill read in time, just got stuck with a bunch of little things, some
my
fault. i fixed most of it. its working, still trying to figure out
base
issue, i hesitate to say bug now.

im looking at vbox guest iso of seconion, seems pretty bloated, runs
slow even set with 3.5 gigs of mem on the host dedicated to it.
however, i plan to look more into /etc/nsm.

thats all for now... thanks every for your help. i muddle through
some
docs in my spare time.

Hi,

Compiled rules (so_rules) are covered in the manuals and blogs in
some depth, however, since I know you don't like to RTFM ;)
(actually I *do* suggest you go to the snort blog and VRT blog and
lookup posts about so_rules and read them in your spare time...),
basically they are pre-compiled rules that either require more
processing than text rules require, or there is some reason to
obscure what the rule is looking for (due to NDAs that SourceFire
has with vendors, or hide things from badguys, etc...)  That's my
understanding of so_rules.

I would suggest that you get snort and the rest of the tool chain
working first before diving into so_rules.  Pulled pork will
handle so_rules as well... you just need to specify the right
distro/bit-ness.  In the past I've had success using Ubuntu
so_rules for not *quite* the same revision, but you'd need to test
that.

It's easy to tell if it's not working, since snort segfaults (or
complains at startup sometimes) if you have the wrong so_rules.
 Sometimes (I've seen this in the past, maybe it doesn't do this
anymore) it doesn't segfault until you get a packet that tries to
hit the so_rule... but the rest of the time it runs happily.

this leads to another issue, so_rules, i did not see ubuntu 12.04
listed, only up to 12.04. is there a updated precompiled rule set
for
12.04 coming soon, not that i know what they are for, i figure
packets being analyzed should matter what distro it is coming for?

i assume the precompiled rules are for base services included in
each linux different distro, thus the need to specify them in the
first place. 

dont answer that, i will figure it out, just thinking out loud..
