| By default, cracks will be written to hashcat.potfile - you don't need -o. If you use -o, hashcat assumes that you're semi-automating something and a lot of the output is suppressed. |

| Well, my point was that if you could just start a run from the other end, you wouldn't have to calculate keyspace at all (for the case of two attack systems) |

Two things, though:
