you will need a merged (old style) password file to give john, and i
believe there are some easy programs you can run as root to accomplish
this (although i don't know their names off hand). What i mean is
generally these days most unix like systems have a password file without
actual password hashes in them that are world readable, and a separate
file/db containing the password hashes for each account that is only
readable by root. they must be merged into one file for john to crack.
then i think it's a simple as typing 'john passwordfile' if you want brute
force rather than dictionary.
