john 1.6-39ubuntu1 (sparc binary) in ubuntu edgy

 john, mostly known as John the Ripper, is a tool designed to help systems
 administrators to find weak (easy to guess or crack through brute force)
 passwords, and even automatically mail users warning them about it, if it
 is desired.
 .
 It can also be used with different cyphertext formats, including Unix's
 DES and MD5, Kerberos AFS passwords, Windows' LM hashes, BSDI's extended DES,
 and OpenBSD's Blowfish.
