Yeah, the Wake On Lan option is what you need, or WoL. Although some
BIOSs put it in odd places and call it strange things.

I leave my viglen on 24x7 and when I want to wake other machines up at
home (remotely or otherwise) I use the etherwake command:-

sudo etherwake 00:1B:FC:XX:XX:XX

It wakes up the other machine and a few mins later I can get to it via
whatever protocol I need.

Cheers,
Al.
