Snort is one tool used by alot of IT guys to block file sharing programs.
THe trouble with these programs is that they have built in port "movers"
that will scan the local network to find an available port to work on.
Scripting is one way to do it....but that mostly just alerts you to the fact
that there is traffice being used on your network for file sharing. I would
like to know an exact way to block file sharing as well...

Due to the legal issues, I am trying to block access to sites like Kazaa and
Limewire in the office.  If I am not mistaken, these networks can use
different ports each time, so there is no way to block it at the firewall.
Is this right?  And if so, what is the best way to block access to these
types of sites?

Many thanks,
Mark J.
