RE: Blocking Music Sharing.

["Zach Forsyth" <Zach.Forsyth () kiandra com>]

Cael,

I would suggest surfcontrol instant messaging filter if you are going to
use a commercial based product. It is designed specifically to
block/filter IM and P2P protocols at a corporate level. URL for more
info is here: http://www.surfcontrol.com/products/im/

Runs on PIII-400 and above.
256mb ram and above
Logs to SQL, and is only a 40mb download. 
I believe there is a 30 day trial available.

The software is able to filter content based on the proprietary network
protocols the IM and P2P apps use. 
In addition you can also block specific IP ranges. 
As has already been mentioned, blocking specific ports, has always been
a poor implementation of IM or P2P blocking.

They also sell a web filter, for general url/host/domain type filtering,
and an email filter. 
All of their products have hugely configurable rulesets, and I have
enjoyed using them over the last few years.

I don't work for surfcontrol - just appreciate their technology and
products.

Cheers

Zach
