Nexapp - Wake-on-LAN (EtherWake)
Wake-on-LAN (EtherWake)
Wake-on-LAN (WoL) allows a powered-off or suspended device to be turned on remotely by sending a special network message called a Magic Packet to its network card.
On NexappOS, WoL is supported through the EtherWake command-line tool. EtherWake is available in the official repositories but not installed by default.
Note: The target device must support WoL and have it enabled in both BIOS/UEFI and NIC settings. If WoL is disabled on the device, it will not react to Magic Packets.
Installation
Install EtherWake from the terminal:
opkg update
opkg install etherwake
These packages are not preserved during system upgrades. See Restore extra packages if you need them reinstalled automatically.
Usage
To wake a LAN device, you need:
- the MAC address of the device
- the firewall interface connected to that LAN segment (example:
eth0)
Basic command:
etherwake -i <interface> <MAC>
Example:
etherwake -i eth0 00:11:22:33:44:55
That’s it — if the device supports WoL and is wired to the same LAN, it should power on within a few seconds.
