wolff - utility to send wake-on-lan packets

wolff

wolff sends WoL packets using the UDP protocol with a configurable port number, but defaults to a port of 9 which is a defacto standard.

Arguments

mac=<addr>
specify the MAC address of the system you want to wake up

host=<ip>
IP address to send the magic bytes to via UDP. Defaults to 255.255.255.255 which is the "this network" broadcast address.

port=<port>
port number the UDP packet is sent to. Defaults to port 9, which is a defacto standard when sending WoL magic packets.

WoL (Wake-on-Lan)

referencing its wikipedia article: wikipedia.org/Wake-on-Lan

The Magic Packet needs only to contain specific bytes within it's payload. It does not need to be any specific protocol or use any specific port. As long as WoL is enabled, so the NIC keeps power when the computer is asleep, it will be looking for a run of six FF bytes followed by the MAC Address of the system you want to wake, repeated sixteen times.
