Perhaps the best way to send information across the network is within UDP packets to a so called "broadcast address". These addresses end with 255, for instance in my home network the broadcast address would be 192.168.1.255. Using TCP, a connection is made between the two computers, and each packet sent must be acknowledged. With UDP sent to a broadcast address, the sending machine sends out a packet and that is the end of it. Every machine on the network can listen for the message and then process it. UDP is an "unrelable protocol", if a receiving computer misses the packet, it has no way of asking for a repeat. On a lightly loaded LAN, this is usually not much of a problem. I am a Linux newbie, so I can't offer specifics for our problem here.
