A simple program that can send “magic packets” to wake up sleeping computers supporting Wake on LAN (called Wake for Ethernet network administrator access in Mac OS X).
WakeOnMac sends a special broadcast packet over a local area network to wake a specific computer from sleep (and in some cases, it can power on a computer when it’s off). Computers that work with Wake on LAN listen on the network for these special “magic packets” even while asleep (and again, in some cases, when powered off). When a computer receives a magic packet, it wakes up.
