One quick and easy solution for Snort (to see if it will work for you)
is to try out the Knoppix-STD live cd. Boot this guy up from the CD or
ISO and you are up and running. Lots and lots of tools.

It may be worth having a look into Snort(http://www.snort.org), I'm pretty
sure this could be made to do what you want, and could even send off some
alerts as well.
Back when Code Red was still around I had this setup on one of our
permitter boxes to do the same thing, and then send a mail to
abuse@<domainnamehere>. Worked quite well.

Hi all,
in the past days our network was stressed from a lot
of network worm (not find from local antivirus,
already up to date) with a stop of the traffic caused
from a lots of arp request. The last one was the
WORM_SDBOT.ACJ a worm that propagates itself using
network shares and a worm that trend micro (up to
date) was unable to find, causing the saturation of
the network switches and the related stop of all the
work. The question is: "is there the possibility to
setup an instrument (even linux based) to sniff the
network traffic with capabilities to find worm?". We
have already a linux based tool for network
monitoring, this tool is useful to isolate host with a
lots of ARP request (typical of the worm), but this
tool can't point us to which worm is doing the
traffic.

Thanks a lot
Luis
