Description:
Commandline tool to allow sending arbitrary IP packets
SendIP has a large number of command line options to specify the content of every header of a RIP, TCP, UDP, ICMP or raw IPv4 and IPv6 packet. It also allows any data to be added to the packet. Checksums can be calculated automatically, but if you wish to send out wrong checksums, that is supported too.
