Broadcasting a UDP datagramPacket over LAN

StackOverflow https://stackoverflow.com/questions/19799481

Question

I am a beginner in Network programming. And I am trying to build a peer to peer network application using UDP Datagramsocket in java. and I need to broadcast messages between the peers on different hosts (PCs running windows 7 connected to my local area network).

and I use the following code to broadcast a message:
mySocket = new DatagramSocket(myport);
mySocket.setBroadcast(true);
broadCastPacket = new DatagramPacket(packetbroad, packetbroad.length , InetAddress.getByName("255.255.255.255"), 11235);
mySocket.send(broadCastPacket);

when I test this on a single PC it works fine. But the problem occurs when I test it on different end systems ( hosts / two PCs ) : No one of these two hosts receive any broadcasted message from the other although my router enable broadcasting and all firewalls on all hosts are disabled. could you please help me ?

Was it helpful?

Solution

problem solved replace the broadcast IP "255.255.255.255" by the Local area broadcast Address "192.168.1.255"
