Killing a linux socket from the shell (gentoo amd64)

Question

People, what is the best way to kill an established connection from a shell in Linux?

It seems that there are tcpkill and 'cutter' tools available, however the amd64 keyword is disabled on my gentoo amd64 tcpkill and when it is used, the cutter displays the error message “openning / proc / net / ip_conntrack: This file or directory is missing” .

Is there any other way to kill the connection?

Thanks.

Answer 1

2.4_beta1-r4 dsniff (containing tcpkill) is marked as "only" as "amd64", so you can give it a shot anyway.
(not really a programming issue though ...)

Answer 2

Any specific reason you can't use kill or pkill (along with netstat ) to find a process that has a connection and then kill it?
