Install gnu screen

GNU screen is a utility which allows you to detach from a terminal session. This is useful for long running scripts. For example, you can ssh in, start screen, start a big copy (cp) job or whatever you like and then press Ctrl-a-d to detach, exit ssh, go on vacation for a week, connect with ssh and reconnect to your original terminal session. If none of that makes any sense to you, you don't need this.

Installing gnu screen:

1. Open ssh session.

2. Type "apt-get update" at the # prompt. You can safely ignore the error about the readynas signature and continue on.

3. Type "apt-get install screen" at the # prompt.

At this point, screen works but the Backspace key may not, to resolve that, create a file called .screenrc in /root which contains:

bindkey -d ^? stuff ^H
bindkey -d ^@ stuff ^H

Now you should be able to enjoy screen by typing screen.
