Simple DOS.
This implements a bit more advanced tool that listens for TCP packets with the ACK or PSH-ACK flags set, crafts a valid TCP RST packet for the connection and sends it through a raw socket. This should result in a denial of service for the host computer and possibly for other hosts in the same network segment.
