However, sending a message to all clients (is that the same as "broadcasting"? - the clients may not be on the same LAN, necessarily) - is not working. EDIT: Okay, well, using SmartSniff I see that when the server sends a broadcasted UDP message, it goes to IP address 255.255.255.255. It's sending correctly but the client is not reading it. But wouldn't that send the message to only computers on a LAN, or does it go to all connected clients? Either way, for small packet sizes (each less than 50 or 100 bytes), would it be okay to store each client's address in a container then loop through it and send each message individually? What's the best way to send and receive UDP messages on a larger scale like this? (Being one server sending to many connected clients.) Thanks! -Matt Another Edit: I did some more research and see that "multicasting" may be an option. However it looks like it has some restrictions... so how should I do this?

Okay, well after some experimentation, I'm noticing that since my packets are small (under 50 bytes), it doesn't take much time to send/recv a set to and from each client. I've decided to just use a for loop through a vector of client addresses. If somebody has a better way, please enlighten me. Thanks ![]() |
