Has anyone experience with WOL under Fedora? If so, how exactly do you put the machine to sleep, and how exactly do you wake it up remotely?
I recently acquired an HP ML110 server (G5 Xeon 3065). This is said to have Wake-on-LAN capability, but when I suspend it to RAM I do not seem able to wake it remotely.
Should one (or can one) suspend to disk for this purpose?
The OS doesn't need any support for WOL, all the settings are done in the BIOS. Sometimes it's a setting that only says "low power mode" - when it's enabled, no power is sent to the network card while the computer is asleep, so no wakeup is possible. A simple way to check is to look at the NIC while your computer is in sleep - the ethernet connection light(s) should be on
Thanks for the response.
Firstly, I have "Wake on LAN" enabled in the BIOS.
Secondly, rather to my surprise the ethernet light goes off when I "Hibernate" (I should confess at this point that I am running Centos-5.3 on this machine, but thought that I was more likely to get a helpful response on the Fedora list!) but stays on when I shutdown.
In neither case does ping or (attempted) ssh have any effect. How exactly is one meant to "wake from LAN".
