There's a tool called tcpkill. You can usually get it by installing dsniff.

[root@fresh ~]# tcpkill -i eth0 tcp port 22
tcpkill: listening on eth0 [tcp port 22]

	Uhm. Who marked this community wiki ? – cnicutar Nov 2 '11 at 18:04
	Apparently you did. There is only 1 revision. And says "[made Community Wiki]". stackoverflow.com/posts/7985103/revisions - weird though, maybe an accidental click on the wiki checkbox? – chown Nov 2 '11 at 18:46
	@chown Maybe :) – cnicutar Nov 2 '11 at 19:02

tcpkill is the command to research, let's you kill connections to / from a specified host, network or port.

For example, to prevent any connections to the host www.google.com use this command:
/usr/sbin/tcpkill −9 host www.google.com
