The whole point of ssh is to prevent this sort of thing, by encrypting the message traffic over this insecure communication channel. An attacker may be able to intercept the encrypted traffic, but it will take a skilled cryptanalyst and a lot of CPU time -- or the attacker will have to be very lucky -- to decrypt the message and recover the passwords while they are still valid. (You *do* change passwords periodically, don't you?) _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
