Base has some dependencies, but there are more pros than cons.

Oinkmaster, use 'modifysid' to turn the rule off, look in the documentation or 
even in the oinkmaster.conf file.

I was under the assumption if the rule is edited and ID remains the
same it will not be overwritten on next oinkmaster update..Am i
mistaken here?

If a rule is edited and the ID remains the same, the rule WILL be overwritten 
(hence why I recommend you edit a COPY of our rule, as opposed to editing our 
direct rule, because if you modify our rule, then use oinkmaster, all your 
changes just got zapped).

I'd rather edit manually, but I have alot of stuff that does it for me.

Thanks Joel.
I tried SC 2 ...as crappy as SC 1 really. Lots of bugs and still does
nothing for me.
I tried installing base but got a lot of dependency issues and gave
up. I will try again.
On oinkmaster how would I shut off your rules specifically?

I haven't done IDSPM yet because it is Windows based. I wonder why
there is no proper linux-based console...But I will provision machine
and do it. Would you recommend that over editing manually?
thanks

First off, ditch ACID. :-)  Use BASE.  base.secureideas.net  ACID is dead.

There's a couple ideas I can give you, one:  IDSPM from 
http://www.activeworx.org
two:  http://www.sourcefire.com :)
three: Sguil (Bamm, am I right with that?)

I think I heard of a SnortCenter2 as well.  Try checking for that.

Also, if you are editing the Sourcefire signatures, it's recommended that 
you copy the rule you are editing to 
local.rules, edit it, and shut off ours using oinkmaster, and in the rules 
file.

Also, ensure that your variables are accurate as well.

I have a Snort-Mysql-Acid-Snortcenter setup.
I am using Snortcenter to update my signature files to my 6 sensors.
The problem I am having is Snortcenter does not edit the signatures
correctly in the DB so my Snortcenter updates overwrite my exisiting
changes in the snort.conf files (any tuning or removing of
signatures).
What alternative is there to snortcenter that I can use to tune
signatures from a central location and push out?
thanks
