Using Tcpkill To Kill Connections Ubuntu 10.04. It is possible to quickly kill a connection to an ip address or port. First install the dsniff package. Now in order to kill a connection to an ip address type
sudo tcpkill -i wlan0 host 126.96.36.199
Where "wlan0" is the interface you want to use and 188.8.131.52 is the ip address you want to block.
If you wanted to block traffic to a certain port it would be
sudo tcpkill -i wlan0 port 80
That's it. Thanks for watching.
