[Flightgear-devel] Another question (udp sockets/broadcast)
I'd like to have a process that does a udp broadcast of key flightgear data. I'd then like to have more than one process on the same machine reading the broadcast packets. Assuming server == the recieving side, and client == sending side. I will have one client sending, and I want multiple server's receiving. However, I can only open one receiving server on my machine. Subsequent processes fail to open the socket returning Address already in use. Is there a magic flag I need to set, or am I just out of luck?

Are you sure you're using the broadcast address configured for your ethernet device? I might be wrong on this, but I believe the kernel should let you bind multiple sockets to the same port on this IP. If you're using a normal UDP port, then this is correct behavior. The kernel won't deliver the same packet to more than one socket. Andy -- Andrew J.
