knoppix-std is a great program that boots to linux beware when downloading that it is a 600 meg *.iso file so u need a burner that burns images (i think all do) like aHead nero it has so much to work with like pass brut forcers, tracerouts, honeypots, firewalls, exploit scanners, the whole works u can dl at www.knoppix-std.org o yea and its free which makes it even better
