Carey, I'm not an authority, but as far as I know, this kind of usage comes from unauthorized servers. The way you stop unauthorized servers dead in their tracks is to set your firewall so your only servers that can hit the Internet are on port 21 (ssh). And if you don't ssh into your Linux box, then set your firewall to block port 21 also.
That will block incoming connections. OP's problem of outgoing connections still remains.
Firewalls can be used to block both outgoing and incoming. Now if you mean that Carey is purposefully accessing a client to a server that sends him tons of stuff, that's a different matter and the solution is to quit using that server. SteveT Steve Litt http://444domains.com
