Setting up Wake on Lan

By Dan Aukes

    Wake on Lan

    On the waking computer

    sudo apt install -y etherwake ethtool

    On the computer you want to wake

    sudo apt install -y ethtool

    then use it

    #ethtool <your-interfacename>
ethtool eth0

    look for the WOL option to see if it’s available

    To wake

    #sudo etherwake -i <your interface> <other MAC address>
sudo etherwake -i eno1 90:B1:1C:77:31:0F

    Create a service

    [Unit]
Description=Enable Wake-up on LAN

[Service]
Type=oneshot
ExecStart=/usr/sbin/ethtool -s <your-interface> wol g

[Install]
WantedBy=basic.target

    sudo chmod 644 /etc/systemd/system/wol.service
sudo systemctl enable wol.service
sudo systemctl start wol.service
sudo systemctl status wol.service

    Disable Network Manager

    list connections

    nmcli connection show

    look for the ethernet connection

    nmcli connection show id 'Profile 1' | grep -i wake

    should look like this:

    802-3-ethernet.wake-on-lan:             default
802-3-ethernet.wake-on-lan-password:    --

    sudo nmcli connection modify 'Profile 1' 802-3-ethernet.wake-on-lan magic
