duplicate a HD over a network (Score 1)

This will do a dd(1) copy across the network if you don't want to drag the HD out and plug it in locally. Of course it takes a while :)

    dd if=/dev/hda bs=64M | rsh ip_or_name dd of=/dev/hda bs=64M

Change the /dev/* as required.

apols if I got the syntax wrong, but you get the idea (dd might need to explicitly ref stdout/stdin; cant rem)

Oh, and it helps if the new drive is the same size (or bigger).
