I have configured WOL on my Asus E35M-pro. But I have some very weird side affects :

  1. Wake on LAN causes GRUB to have no countdown timer when activated unless I use update-grub
  2. When I shut the machine down, it automatically reboots when WOL is active the only way do shut it down is to force it by holding the power button.

My server is behind a normal switch to which my computer, with whom I issue the magic packet, is attached as well.

Could it be the magic packet remains floating around ?

Could it be the magic packet remains floating around ?

You could find out by running tcpdump on the interface. Usually, there would be nothing "floating around" unless you have a network loop - which in turn would have other nasty symptoms.

I have no idea about why GRUB is behaving differently when waked from LAN. But I have seen some BIOS implementations where any network traffic would trigger a power on - not just the WoL magic packet. Check if you can change your power settings to be "ACPI controlled" in the BIOS setup.

There is no option to change the ACPI. And I don't have a network loop. I also tested it by removing the network cable right after issuing the shutdown command and it would still reboot. – Lucas Kauffman Jan 14 at 12:07
Then something is probably broken or buggy. Try updating the BIOS to the latest/greatest and if the problem persists, open a call with Asus tech support. – syneticon-dj Jan 14 at 14:10
Guess Im going to do that last one, because I already updated it to the last one :/ – Lucas Kauffman Jan 14 at 14:16
