This problem has been posted a couple of months ago by someone else without answer: I'm just running the Sun example program for Multicast sockets. The server works fine, the client starts with:
MulticastSocket socket = new MulticastSocket(4446); InetAddress address = InetAddress.getByName("230.0.0.1"); socket.joinGroup(address);
<<<< ;<< breakdown, error No 10055 SocketException, set socket option failed
This happens on some Computers, on others it works, anybody an idea about the problem?
If I run a Tcp-based server client pair (ServerSocket and Socket as Java functions) everything works fine, it's the Multicast that causes the problem.
