29.Sh DESCRIPTION
30The
31.Nm
32program is used to send Wake on LAN (WoL) frames over a local
33Ethernet network to one or more hosts using their link layer (hardware)
34addresses.
35WoL functionality is generally enabled in a machine's BIOS
36and can be used to power on machines from a remote system without
37having physical access to them.
38.Pp
39.Ar interface
40is an Ethernet interface of the local machine and is used to send the
41Wake on LAN frames over it.
42If there is only one Ethernet device available that is up and running, then the
43.Ar interface
44argument can be omitted.
45.Ar lladdr
46is the link layer address of the remote machine.
47This can be specified as the actual hardware address
48(six hexadecimal numbers separated by colons)
49or as a hostname entry in
50.Pa /etc/ethers .
51.Nm
52accepts multiple
53.Ar lladdr
54addresses.
55Link layer addresses can be determined and set using
56.Xr ifconfig 8 .
