It wakes up hardware that is Magic Packet compliant. wol - Implements Wake-on-LAN functionality in a small program.gWakeOnLAN - GTK utility to awake turned off computers through the Wake-on-LAN feature.Keep in mind that most routers by default will not relay subnet directed broadcasts as a safety precaution and need to be explicitly told to do so.Īpplications that are able to send magic packets for Wake-on-LAN:

In this scenario, the external IP address of the router must be known. If used to wake up a computer over the internet or in a different subnet, it typically relies on the router to relay the packet and broadcast it. The knowledge of an IP address for the target computer is not necessary, as it operates on layer 2 (Data Link).

In its simplest form, Wake-on-LAN broadcasts the magic packet as an ethernet frame, containing the MAC address within the current network subnet, below the IP protocol layer. $ ip link 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default To obtain it, execute the following command from the machine: To trigger WoL on a target machine, its MAC address must be known. When using TLP for suspend/hibernate, the WOL_DISABLE setting should be set to N in /etc/tlp.conf to allow resuming the computer with WoL. Wifi.wake-on-wlan = ignore Enable WoL in TLP You can disable Wake-on-Lan for all connections permanently by adding a dedicated configuration file : The Wake-on-LAN settings can also be changed from the GUI using nm-connection-editor. To disable Wake-on-Lan, substitute magic with ignore. # nmcli c modify 'wired1' 802-3-ethernet.wake-on-lan magic # nmcli c show 'wired1' | grep 802-3-ethernet.wake-on-lan 802-3-ethernet.wake-on-lan: defaultĮnable Wake-on-LAN by magic packet on that connection: Wired1 612e300a-c047-4adb-91e2-12ea7bfe214e 802-3-ethernet enp0s25īy following, one can view current status of Wake-on-LAN settings: One way to enable Wake-on-LAN by magic packet is through nmcli.įirst, search for the name of the wired connection: NetworkManager provides Wake-on-LAN ethernet support. etc/netctl/ profile ExecUpPost='/usr/bin/ethtool -s interface wol g' NetworkManager If using netctl, one can make this setting persistent by adding the following the netctl profile: First, make sure cron is enabled, and then edit a crontab for the root user that contains the following /usr/bin/ethtool -s interface wol g The $name placeholder will be replaced by the value of the NAME variable for the matched device.Ī command can be run each time the computer is (re)booted using in a crontab. etc/udev/rules.d/ les ACTION='add', SUBSYSTEM='net', NAME='en*', RUN+='/usr/bin/ethtool -s $name wol g' Otherwise, NAME would be undefined and the rule would not run. The file name is important and must start with a number between 81 and 99 so that it runs after les, which renames interfaces with predictable names. The following rule will turn on WOL on all network interfaces whose name matches en*. Udev is capable of running any command as soon as a device is visible.

This is an equivalent of previous systemd.link option, but uses a standalone systemd Īlternatively install the wol-systemd AUR package, then activate this new service by starting rvice.

In the Match section, OriginalName= can also be used to identify the interface.

This configuration applies only to the link-level, and is independent of network-level daemons such as NetworkManager or systemd-networkd.

To be considered, the file name should alphabetically come before the default 99-default.link.The content of the default link file /usr/lib/systemd/network/99-default.link shipped with systemd has to be included, otherwise the interface might be misconfigured. Only the first matching file is is applied.
