I need to use snort to look at the packet content and block on that . I
cant simply block a port because the ports are in use for regular client
tasks ( ususally) and the updates may or may not go though them ..theres
no way to tell yet.

I would love to block the updates just using port blocking on my
firewalls there .. but i cant block ports without making the software
useless. This is where both snort's IDS and sniffing functions come to
play together.
