KillRogues

This small program is for finding and disconnecting machines located on a Cisco switches composed-LAN. It’s useful for kicking rogues machines off your network. Give it the IP or MAC address of a machine, the credentials to one of your switches, and it will find its way to the target machine and offer you to switch off the switch port it's plugged on (don't worry it can also switch it back on).
