I take no credit for this as the info was taken from a few places but I got WOL working on my Ubuntu boxes by doing the following (after making sure the necessary options were enabled in the BIOS):

1. Edit the /etc/init.d/halt file and change the "NETDOWN" option to prevent network interface being disabled at power-off.

Code:

NETDOWN=no

2. Run the following command to check the status of eth0 - you are interested in the "Wake-on: x" line (you want it to be "Wake-on: g").

Code:

sudo ethtool eth0

3. If it isn't set to "g" already, run the following command.

Code:

ethtool -s eth0 wol g

4. To force this option to be set at power-on, add the following to /etc/rc.local (before the "exit 0" line).

Code:

# set network card to listen for Magic Packets
ethtool -s eth0 wol g

5. Reboot your system before testing.

Note: This is the list of options for waking with WOL:
p Wake on phy activity
u Wake on unicast messages
m Wake on multicast messages
b Wake on broadcast messages
a Wake on ARP
g Wake on MagicPacket™
s Enable SecureOn™ password for MagicPacket™
d Disable (wake on nothing). This option clears all previous options.

This is all that was needed on my HP N36L server but on my Acer Revo 3610 I found that in the BIOS, I had to enable WOL but also disable the option for "allow deep power off" (something like that) - the option under WOL.
