Just messing with a script on our linux firewall to watch / block P2P traffic.

Seems like bittorrent makes a gob load of UDP connections when running, i downloaded ubuntu 10.10 and got about 600 UDP connections.....

So If i count UDP connections by NATted IP address, i'll see... = 10 = 600

Skype also makes lots of UDP connections, but nothing like what bittorrent does from what I can see.

I may just visit the user at and check that their PC is not being naughty.....

Thoughts from another geek please?

Most peers and seeds still use TCP.

However uTorrent's uTP uses UDP

The most effective (but certainly not foolproof) way at present is to try and block access to trackers.

Some clients will also use IPv6 and/or try to setup a toredo tunnel, so watch for that too.
