jc-wepcrack is a distributed WEP cracker. It uses its own sockets-based protocol for communication. It can easily be installed on a lab or your own cluster. It supports any key size. Other features include the ability to save/restore the state of the server to disk and a fancy ncurses interface. It is architecture neutral, and was co-developed on a G4 Powerbook and an x86 Linux machine. If you only have one machine, it will still run.
