[Cialug] Using dd and netcat to move a disk

[Nathan C. Smith]

Thanks gents.  I just wasn't being patient, it did finish, must have had to spool out a buffer?

I learned about process states while I was waiting, good tip.

It should return to the prompt.

dd should close the output stream when it's done; netcat should exit when the input stream is closed.

If you can get to another terminal I'd check to see what state dd and netcat are in.
