cutter

disconnect routed IP connections

Cutter will send packets to both ends of a TCP/IP connection to close the connection. It is designed to be used on a Linux router to disconnect unwanted connections. Cutter can close all connections to or from a specified ip-address or ip-address/port pair, allowing, as example, close the specific service of a computer. It also can close the connections between two ip-address that use a specific port to deny a certain service to client. Other possibility is close a specific connection from ip-address/port to ip-address/port. Cutter is not a firewall, but is part of a larger Linux firewall project. Cutter 1.04 should be considered EXPERIMENTAL.
