So Breaking passwords with John The Ripper Clusters won, so today and
some Linux and *nix buddies started to setup the John The Ripper
Cluster over a virtual private network and communicating with psi in
our own Jabber Conference room. For a while, I was stumped, but
determined to make this work because I kept getting the message "No
password hashes loaded". I tried manually creating the file with hash
for JTR to break, creating it with unshadow, and several other
attempts to make this work, so I finally put into google the "No
password hashes loaded". What I found out is since the md5 hash
exploit which means you can get any password from an md5 hash, Ubuntu
has upgraded their hashes in the /etc/shadow to SHA2. Now, there are
going to be a lot of disappointed people :( . I may just need to go
with the next most popular vote. This email is a few months old, so I
need to do an svn checkout or a git clone, and see what progress they
have made as well as getting on the mailing list and asking there.
