This program listens for packets on a specified UDP broadcast. When a packet is received, it sends that packet to all specified interfaces but the one it came from as though it originated from the original sender.
The primary purpose of this is to allow games on machines on separated local networks (Ethernet, WLAN) that use udp broadcasts to find each other to do so.
make ; cp udp-broadcast-relay /some/where
/some/where/udp-broadcast-relay [-d] [-f] id udp-port eth0 eth1 ...
udp-broadcast-relay must be run as boot to be able to create a raw socket (necessary) to send packets though they originated from the original sender)
- I run debian woody with Linux 2.4.20, and here it works.
