Remotely restart Timbuktu when it stops responding
Authored by: bukweet on Mar 25, '09 08:37:48AM
Great tip! I'll try this one out tonight.
Now, does anyone have a method to remotely wake a sleeping Mac over the WAN (behind an Aiport router, which doesn't pass a wake-up packet)?

Remotely restart Timbuktu when it stops responding
Authored by: mzs on Mar 25, '09 09:27:48AM

I have never encountered a computer that can wake when receiving a magic packet over wifi, only ethernet cable. If that is what you mean, I think it is hopeless.

If you have the computer connected via an ethernet cable to the airport base station then there may be hope. You need the base station to either have a static ARP table entry for the computer or the base station needs to broadcast the magic packet. I have no idea if airport base stations can do that, I've never used them. If you try to just send a magic packet and the router (base station) does not have an ARP table entry for the IP addr, it will first do the "ARP who has ..." and not hear back, so it will never send the magic packet to wake the computer. I successfully use the broadcast the magic packet to wake the computer from a linksys AP running tomato that I ssh into.
