as shown below it loaded 838 and 3229 hashes of which 27 passwords were

I dont believe it is entirely because they are strong passwords, if thats
the case. its from about 12 different boxses with I dont believe any
addtional security in place.. there has GOT to be more then 1 weak password
out of a total of 838 hashes... and more then 26 out of 3229 hashes.. so Im
kinda clueless as to why its not cracking properly.. I think Im gonna try
reinstall john with the newest version but I dont see that changing much.

Im not sure what else information I can provide to see what excatly is going
on.. =/
