I can start an opencl session (one master, two remotes). I can ssh into the remote computers, enter into the john/run directory and see the session log and .rec files. 

Keep in mind that the only trouble I'm having is restoring a session! My master node is only producing one .rec file.

cd /home/tony/bleeding-jumbocl/run/

./john - -form:wpapsk-opencl -dev=cpu --wordlist=rockyou.txt --rules jtr.hccap

 If I  ssh into the remote computers and enter the above command lines, I'll get that segment fault.

 If I  enter this command line instead, (without the -opencl) everything runs just fine.

./john - -form:wpapsk -dev=cpu --wordlist=rockyou.txt --rules jtr.hccap

Does that indicate an opencl problem??

An opencl problem??

Thanks so much magnum!!
