Subject: Re: Cracking MSChap v2
Question: After running JTR Bleeding Jumbo for 27 hours I stopped the
process and entered the below with the results shown:
NRO117:magnumripper L7$ ./run/john --show passwd
stat: passwd: No such file or directory
Does that mean that JTR didn't come up with a password or that I did
something wrong?
Thanks!
