Hi guys,

I am trying to crack linux password. I did:

1. unshadow passwd shadow > mypasswd

2. john --worldlist=password .lst mypasswd

I am getting

No password hashes loaded error

Can anyone help me out?

Thanx

Have you check the contents of file mypasswd? Your present working directory container copies of the passwd and shadow files from your target Linux system at the time you ran the unshadow command right?

ya, I looked mypasswd file and it looks ok to me.

I have copy of shadow and passwd file from different machine. I copied those files to my backtrack machine and I am trying to run jtr on the file to get passwords.

So there are valid password hashes in the mypasswd file? That message usually means that there are no supported hashes in the input file. Did you enter the command exactly as shown above with the space between "password" and ".lst"? Assuming your password list is "password.lst" there should be no space there. Im assuming password.lst is in the present working directory?
