At first it worked, and I am amazed why is not working now. It gives me this kind of error now, whenever I try crack a password.

mpirun -np 4 -machinefile machines ./john mypasswd

No password hashes loaded

I am so surprised and shocked because of the fact that the first time it worked, it loaded all the hashes, and all the nodes in the cluster starting working. But, suddenly after that, I am seeing this “No password hashes load”. Any idea what the hell is wrong?

Thanks!!!

This problem is bugging me on my Linux cluster.

I’m not sure this is due to NFS. What you should do is to get an older version of John or compile john from sources with cygwin.
I don’t use john under Windows anymore, so you should ask the developers about it from the mailing list.

Could you be a little more specific and help me out of this. Is the problem related to NFS or something? Is it that multiple MPI processes cannot access the same file on NFS simultaneously? Please help me out!!!!!!!!!!
Thanks

Have a look here: http://www.openwall.com/lists/john-users/2006/11/29/2

You can also use –session:mysessionname, that should fix your issue.

Regards,
Thi.

The testing works fine when I enter the following command

mpirun -np 4 -machinefile machines ./john –test

But when I use the same command for a hash to crack, it gives errors, and john does not use all the machines in the cluster. Here is what it tells me.

mpirun -np 4 -machinefile machines ./john mypassswd

Loaded 1 password hash (generic crypt(3) [?/64])
Loaded 1 password hash (generic crypt(3) [?/64])
Loaded 1 password hash (generic crypt(3) [?/64])
Loaded 1 password hash (generic crypt(3) [?/64])

Node 0@compute-0-1.local: Crash file recovery file is locked: ./john.rec
Node 0@compute-0-3.local: Crash file recovery file is locked: ./john.rec
Node 0@compute-0-2.local: Crash file recovery file is locked: ./john.rec

It doesn’t even use the four cores on my machine when I try to run it on a single computer. When I enter

mpirun -np 4 ./john mypasswd

Here is what it says.

Node 0@locahost.local: Crash file recovery file is locked: ./john.rec
Node 0@localhost.local: Crash file recovery file is locked: ./john.rec
Node 0@localhost.local: Crash file recovery file is locked: ./john.rec

What is the problem, could anyone please help me out?????????

Thanks

If this is not the case then the core number detection by OpenMP fails somehow. Which platform are you using?

Why is that, if I compiled according to instructions?
