Config Wake on LAN

Introduction

[Debian Wiki]
Wake On LAN (WOL) enables other systems on your local area network (LAN) to turn on your system over the network. Support for WOL is required in your network card, motherboard, UEFI/BIOS boot firmware and operating system network configuration.

Enable WOL

BIOS

Normal: Enable “Wake on LAN” in the BIOS.

HASEE: Enable “Network Stack” in the BIOS. It may be set in different place in different bios.

Windows

By default nothing is needed to do.

If you changed some networking settings, you can use following steps:

[Ethernet Properties] → [Configure] → [Power Management] → check [Allow this device to wake the computer]

Linux

Check the state of wol:

first use ifcong to find your ethernet device: e.g. “enp8s0f1” is the name of ethernet device of my laptop
check wake-on-lan status: sudo ethtool enp8s0f1 | grep Wake-on
You may see the following content:
```
Supports Wake-on: pumbg
Wake-on: d
```
if “Wake-on” is “g”, that means you have already turned on wol.

enable the wol: modify the global interface config file /etc/network/interfaces

remember change enp8s0f1 to your device name

$ sudo vim /etc/network/interfaces

# add following content
auto enp8s0f1
iface enp8s0f1 inet dhcp
        ethernet-wol g

WOL modes explanation:

refer to ethtool manual

       wol p|u|m|b|a|g|s|f|d...
              Sets Wake-on-LAN options.  Not all devices support
              this.  The argument to this option is a string of
              characters specifying which options to enable.
              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™
              f   Wake on filter(s)
              d   Disable (wake on nothing).  This option
                  clears all previous options.
