What's the latest status line printed by this command on a keypress?
What version of JtR? What make target did you build it with? Did you
enable OpenMP in the Makefile?
What CPU type and clock rate, exactly? If this is a Linux system, see
/proc/cpuinfo.
Do you have a GPU in this machine, and what type is it? Do you have
another machine with a decent GPU that you can use for this? What OS?

Please post more info on what you know about the password - lengths
range, character classes present and not present, etc. - and explain why
you think you know that. ;-) We may be able to suggest how to focus the
attack.

It has that information already, or it wouldn't have been able to attack
this hash at all.

It's the same thing.
