About Magic Packets
Wake-on-LAN (WOL) technology is used for remote waking up machines from sleep state through special network packets (Magic Packet).
The Magic Packet is a UDP broadcast message, that contains the Media Access Control (MAC) address of the network card of target computer.
This packet should contain a synchronization stream of 6 bytes of FFh and 16 times the repetition of the MAC address.
There are three different ways to send Wake-on-LAN packets:
* Limited broadcast. Magic Packet sent to the limited broadcast address (255.255.255.255) it is received by all machines on the same subnet but not forwarded to machines on other subnets.
* Subnet-directed broadcast. Packet sent to the target machine subnet. The router or switch will forward the packet to all the machines on the subnet.
* Unicast. Packet sent directly to the machine IP address. If the router or switch still has cached what port that computer is attached to, packet gets access to the machine.
