We open a terminal

Using the following commands we download a script, grant it the necessary permissions and make it run on every boot.

sudo wget rubeninfante.com/ARCHIVOSMIOS/wol.sh
//Lo movemos a la carpeta de ejecución de scripts iniciales
sudo mv wol.sh /etc/init.d
//Le otorgamos los permisos
sudo chmod 755 /etc/init.d/wol.sh
//Le asignamos la propiedad
//Podemos saber nuestro usuario utilizando el comando 'who'
sudo chown TU_USUARIO:TU_USUARIO /etc/init.d/wol.sh
// lo iniciamos como servicio a varios niveles gui command etc
sudo update-rc.d wol.sh defaults
