etherwake [options] mac-address

etherwake sends Wake-on-LAN (WoL) magic packets to wake computers from sleep, hibernation, or powered-off state. The target computer must have WoL enabled in BIOS/UEFI and on the network interface.
The magic packet contains a sync stream followed by the target MAC address repeated 16 times. When the network card detects this pattern, it signals the computer to power on.

-i interface

Network interface to use.

Use broadcast address.

Debug mode; show packet contents.

SecureOn password (6 bytes).

Show version.

Target MAC address (XX:XX:XX:XX:XX:XX).

- Target must have WoL enabled in BIOS/UEFI
- Network interface must support WoL
- Target must be on same network segment (or use directed broadcast)
- Target's NIC must have power in standby

Requires root or CAPNETRAW capability. Works on local network only; WoL over internet needs port forwarding or VPN. Some NICs need specific driver configuration. Wireless usually doesn't support WoL.

Wake-on-LAN was developed in 1996 by AMD and HP as part of the Advanced Manageability Alliance. etherwake is one of several Linux implementations of WoL sending tools.
