Here is the source.

Activate WOL in bios:

First, reboot the remote server and go to BIOS > Power Management > “Wake On LAN”. Turn it on. Next, save and close the bios.

Install ethtool:

apt-get install ethtool

Enable:

ethtool -s enp9s0 wol g
# ethtool -s <interface> wol g

Check if enabled:

ethtool enp9s0
# ethtool <interface>
# Output:

The most important thins is to check these two lines(g should be present):

Supports Wake-on: pumbg
Wake-on: g

You should also make it run at boot-up. Add this is /etc/rc.local:

#!/bin/bash

ethtool -s enp9s0 wol g

exit 0

Then make that file executable:

chmod +x /etc/rc.local

Reboot and check if you get Wake-on: g.

To access it from Internet, add a port forwarding in your router settings, to port 9 (UDP) on your PC.

Example if my PC has the ip 192.168.2.101 and the external port(from the router is 999) it will look like this:

public_ip:999 UDP -> 192.168.2.101:9 UDP.


Turn your pc from linux pc:

apt-get install wakeonlan
wakeonlan -i IP -p PORT MAC

From android.
