Actually quite stupid of me. You can configure the firewall to block outgoing traffic based on the target port. Don't know the firewall command since I am using webmin to configure shorewall, but the target ports you wan't to block are: 6882,4444,4662,1214,6346,9999,9074,2234 That covers just about all the p2p servers. I think that should do the job. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
