Wake-on-lan support?

I can back up the post from Mr. Sawyer. Last year I wrote a small app (windows, unfortunately) for waking my MacPro with magic packets. It worked great sitting in my living room and connected via my wireless router, but when I tried from work I got nothing. Thats when I learned about the internet not passing the magic packets (and many other things). I thought it might be possible to set something up that would send an http request to a non-sleeping device on the same network with your MacPro and have that device then send the WoL packets. Unfortunately that idea never made it out of the "I wonder if..." stage.

I have a similar behaviour. I use WakeOnLan for Mac OS X ( http://www.readpixel.com/wakeonlan/ ) for waking up a Mac Pro through the Internet from a remote MacBook Pro. I use After I put the machine to sleep, I am able to wake it up deterministically within few hours. After that, the machine wakes up only rarely (10-20% of the times).
Would be nice to have feedback from Apple on this. Their claimed support for WakeOnLan should be clarified better.

Yes, a Mac Pro (and all current and recent Macs) supports WoL, but the Internet doesn't pass directed broadcast, and many routers (particularly in corporate networks) are similarly set not to pass DB, so often WoL won't work.

This might be a little bit off topic, but waking up a computer through the internet is possible. I have a server in the internet running debian and a commandline tool called wol. this tool sends the packets to my router, which routes the request to my desktop (PC with ubuntu). I am a Mac User, but I just have a MacBook Pro and that old PC 🙂

It is quite interesting, because I recognized that if I put my mac pro to sleep and I want to wake it up within a minute, then it works with the website for example dslreports/wakeup. But after two or more minuits, I can't wake up my mac pro anymore. Within my network, by using my notebook, it works perfectly.
Does someone have a solution for that problem ?
Thanks in advance

For remote WOL (from Internet), try a Linux-based router, like a Linksys WRT54GL, flashed with DD-WRT, Tomato, OpenWRT, etc.

Here's a three step example using Tomato: (1) Log into the router interface remotely over https, (2) click the WOL tab for a list of recent machines and MAC addresses, (3) Click the machine you'd like to power-up.

Required parts: a $70 Linksys router (order a GL) and an open-source firmware upgrade ( http://www.polarcloud.com/tomato). You'll find a veritable butt-load of other uses for such a compact and powerful device (including, of course, Internet access and Wi-fi).

Regarding the different remote wake-up behaviour within or after a certain amount of time since when the machine went to sleep, this is most likely related to entries in the ARP tables of some router expiring. After some time that a router doesn't see traffic for your machine's IP address, it forgets that data for that address has to be forwarded on that physical port. Therefore, when trying to wake up a machine from remote, the "magic packet" does not pass through the router to the machine at all.
This can be solved by introducing some always-on low-power programmable appliances that can generate the magic WoL packet from inside the LAN on request. For example, routers that can mount OpenWRT ( http://wiki.openwrt.org/TableOfHardware?action=show&redirect=toh ), e.g. La Fonera and some Linksys, can do this after installing the "wol" package.

There is still the problem that despite the supported features of the Apple Remote Desktop, wake on lan does not wake up the machine when it's completely shut down and not just in sleep mode.

i have no luck waking up my g5 from a squeezebox3, although the sb3 does have a wol feature. my network is wireless, using aebs. are there any of those "always on" progams (you see, i am a hopeless case) for the aebs?
