How does one close an ssh session, which has been disconnected from server ?
use the keycombo "~." , without quotes. For more info, do check man pages.

Prologue

I was happily working on my system, trying to access my test box remotely. And then, there was darkness, or as most people would call it as power failure. Yes, I do not have a UPS as yet ( under repair ) and i ended up with a "hung" ssh session.

If you run ls -la /dev/mapper/ you should see a luks-xxxxxx-xxxxx-xxxx or some such file. That's the mapping that was created when the password di
