Before people start hacking out their own custom versions of SED, please 
try swatch v2.1 (not 2.2).  It does this already and has code to 
automatically do something when a trigger is activated, see below for 
SAMPLE config.  (portcullis is our router)

/portcullis.*login failed/  mail=admin
/portcullis.*restarted/     exec="/usr/local/bin/tpage - `date +%m%d%H%M`:$0"

I've been basically going through stuff and looking for error messages 
that would symbolize something strange.  However, there is a huge number 
of error messages that people have decided mean a security problem.... :)

I have a program called logcheck that does just this. It's a clone of a
log checker found on TIS Gauntlet and works very well with systems
with TCP wrappers and/or the TIS Firewall Toolkit. It works very
well on standard Linux (RedHat, Slackware), FreeBSD(2.x), BSDI(1.1, 2,X)
and other similiar UNIX BSD OS types. 

You can find this program at http://www.psionic.com/logcheck.html

The current version is 1.01, there will be an update to 1.1 in a few
weeks.

This site is on a poor 28.8 connection so please be patient if it is slow.
It is probably mirrored at various archives (COAST), if anyone else wishes
to mirror please feel free.

Thanks,

-- Craig
