What about a fascist passwd program which refers to a dictionary and

One of the sample programs in _Programming Perl_ is a perl passwd that does
just that - checks for length, checks against dictionary files, checks to
make sure you're not using simple two word combinations, makes sure they're
not a social security or phone number, makes sure you're not using your
userid/name, someone else on the systems userid/name, checks for license
plates, sequences of consecutive keys on the keyboard, entries in
/etc/hosts, makes sure that if you're using the "type in the first char of
each word of a phrase" method of generating your password that you don't
use a common phrase, and even keeps a history of the passwords you've used
and doesn't let you reuse them.

It seems pretty thorough.
