I use it to check our students passwords each week. It works very well on cracking the students Linux passwords. However I'm also trying to crack their samba passwords. I'm using the following test password file: Administrator:500:E52CAC67419A9A224A3B108F3FA6CB6D:8846F7EAEE8FB117AD06BDD830B75 86C::: AndAnotherAdmin:700:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:8846F7EAEE8FB117AD06BDD830B 7586C::: a0810440:10435:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:5705E3F43B799D35CF582FF93EDC94D6: [U ]:LCT-4C91BA1A: The first line is from an old samba installation and has both Lanman and NTLM encoded passwords. The second and third lines are from the current samba installation and it only has NTLM encoded passwords. Probably NTLMv2 actually. John cracks the Lanman password for the first line but not the NTLM passwords Administrator:PASSWORD:500:8846F7EAEE8FB117AD06BDD830B7586C::: ^^^^^^^^ Can I get it to crack the NTLM passwords. Thanks, Tony. Tony Molloy CTO. Dept. of Comp. Sci. University of Limerick Ireland
