The magic packet format is very simple: it must include anywhere in the packet 6 times hexadecimal FF, followed by 16 times the Mac's MAC address (pun intended). I use this feature to turn on my iMac from my office when I want to log on using ssh (I have a Solaris machine on my home LAN that runs 24/7). I haven't found any trace of this documented on Apple's web site, but it seems Macs also implement this feature (at least my iMac G4 does). This is used, for instance, to allow backup programs to run at night. This is designed to allow a network administrator to turn on a computer remotely, even when it is turned off, by sending a "magic packet". Most modern computers offer a feature called "Wake on LAN".
