.Op Ar lladdr ...
.Sh DESCRIPTION
The
.Nm
program is used to send Wake on LAN (WoL) frames over a local
Ethernet network to one or more hosts using their link layer (hardware)
addresses.
WoL functionality is generally enabled in a machine's BIOS
and can be used to power on machines from a remote system without
having physical access to them.
.Pp
.Ar interface
is an Ethernet interface of the local machine and is used to send the
Wake on LAN frames over it.
If there is only one Ethernet device available that is up and running, then the
.Ar interface
argument can be omitted.
.Ar lladdr
is the link layer address of the remote machine.
This can be specified as a hardware address
or as a hostname entry in
.Pa /etc/ethers .
.Nm
accepts multiple
.Ar lladdr
addresses.
Link layer addresses can be determined and set using
.Xr ifconfig 8 .
