One of the features of Ethernet is its ability to wake up sleeping computers by receiving a special packet on the network. This feature is called Wake-on-LAN (WOL) and allows users to wake up remote computers without needing to be physically in front of the computer. The special packet that wakes up the computer is called a “magic packet”. Wake-on-LAN requires motherboard support at the BIOS level, and an appropriate network card that scans the network for magic packets.
Magic Packet Format
Since Ethernet operates at the Data Link layer, the network card only inspects a frame if it is either a broadcast frame or the destination address of the frame matches its own MAC address. Thus, magic packets are usually subnet broadcasts (e.g., [url removed, login to view]) or limited broadcasts ([url removed, login to view]), which ensures that the sleeping computers will receive a copy of the frame. Since there is no application listening on the sleeping computers, UDP is used as the transport protocol. Packets are sent to either UDP ports 7 or 9. The frame body consists of the Ethernet broadcast address (FF:FF:FF:FF:FF:FF) and the MAC address of the sleeping computer (6 bytes) repeated sixteen times for a total of 102 bytes.
Note that the “:” betweeb the hexadecimal representation is for human benefit, and is not to be used in the packet.
Write a java UDP client program with the name WOLClient which creates a magic packet and sends it to a sleeping computer with MAC address MAC_ID. MAC_ID should be provided as an argument to the program in the format AA:BB:CC:DD:EE:FF
