Wake-on-LAN (WOL) is an Ethernet networking standard that allows a server to be turned on by a network message. You need to send 'magic packets' to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called systems. Make sure you connect the NIC (eth0 or eth1) with the motherboard, and enable the WOL function in the BIOS [1].
Enable BIOS to support WOL
Power Management Setup => Wake-Up by PCI Card => Enabled
or
Power => Wake on LAN from S5 => Power on
Enable LAN card to support WOL
Install tool ethtool:
# apt-get install ethtool
Add the following to /etc/network/interfaces:
allow-hotplug eth0
iface eth0 inet static
address 192.168.0.55
netmask 255.255.255.0
gateway 192.168.0.1
post-up /sbin/ethtool -s eth0 wol g
post-down /sbin/ethtool -s eth0 wol g
Send 'magic packet'
Install tool wakonlan:
Wake up PC on the same LAN
# wakeonlan aa:bb:cc:dd:ee:ff
where aa:bb:cc:dd:ee:ff is the MAC of the PC being wake up
Wake up PC over internet
# wakeonlan -i 123.1.2.456 -p 6 aa:bb:cc:dd:ee:ff
Send 'magic packet' using UDP to IP address 123.1.2.456 with port number 6. Make sure the destination router forward the magic packet to PC being wake up.
