[TriLUG] software-addressable power switches?

[Andrew Perrin]

Is there a device, reasonably cheap and addressable in linux, that will
let me turn a plug on and off? I'm finding that my cable modem often
(e.g., every 2-3 days) loses its signal, but a power cycle brings it right
back.  I'd like to script this so when the computer can't ping out it
tries to power cycle the modem. But that would require some sort of device
that lets my computer tell a plug to turn off, wait 60 seconds, and turn
back on again. If such a device exists, I'm sure some TriLUGger will know
of it!

Thanks-
Andy
