The first edition of Programming perl had an example script for checking passwords, but it was dropped in the current edition. Fortunately, O'Reilly still has the example tarball on their FTP site.

Re: preventing weak passwords
You can get better versions of passwd(1) that prevent users from setting bad passwords in teh first place - we use one called npasswd, which works a little TOO well (it screens out my attempts to give new users simple passwords). I can give you the source if you need it, but there is a distro site out there. Carl

You may want to consider the debian package for cracklib2. This is a library that will check the quality of the passwords as they are set by the user so it is proactive. Alternately, the author of cracklib2 has another program named crack that will check the quality of existing passwords. Not packaged in debian yet. -- Jean Pierre
