24.Op Ar interface
25.Ar lladdr
26.Op Ar lladdr ...
27.Sh DESCRIPTION
28The
29.Nm
30program is used to send Wake on LAN (WoL) frames over a local
31Ethernet network to one or more hosts using their link layer (hardware)
32addresses.
33WoL functionality is generally enabled in a machine's BIOS
34and can be used to power on machines from a remote system without
35having physical access to them.
36.Pp
37.Ar interface
38is an Ethernet interface of the local machine and is used to send the
39Wake on LAN frames over it.
40If there is only one Ethernet device available that is up and running, then the
41.Ar interface
42argument can be omitted.
43.Ar lladdr
44is the link layer address of the remote machine.
45This can be specified as the actual hardware address
46(six hexadecimal numbers separated by colons)
47or as a hostname entry in
48.Pa /etc/ethers .
49.Nm
50accepts multiple
51.Ar lladdr
52addresses.
53Link layer addresses can be determined and set using
54.Xr ifconfig 8 .
