10.6: Use wake-on-demand to help conserve energy
Authored by: ajmas on Dec 29, '09 04:18:44PM

Details of the technology can be found here: Knowledge Base article HT3774

It can technically be implemented by any software/hardware, but as of now only Apple implements this. More specifically this is available in any Apple Airport Extreme and Snow Leopard set up.

I had planned on using this with my home server, which is on the web, but alas it requires a service to keep its external IP address to host name updated (dyndns.org) and the Apple Extreme does not support this. Ideally, as an alternative, I would have found a $10 piece of hardware that could do this while consuming less than a watt, but I haven't found anything that could do this for me. In the meantime the idle usage of my Mac mini is 25W.

10.6: Use wake-on-demand to help conserve energy

I have found that this seems to work for me (at least I think it does) even though I don't have an Airport Extreme or Time Capsule. My router is just the 2wire gateway provided to me by AT&T. I do have an Airport Express as a client on the network, but I haven't seen the Express listed as having this feature anywhere...

Ajmas,

You can simply install DynDNS Updater on the server itself.

I think Ajmas is probably currently using DynDNS updater, but the goal here is to have it still update while the server sleeps. Some routers can update DynDNS, but the Apple ones don't have this feature. I would also like to be able to do this but I don't have the required hardware.
