POUDP Problem With Non-Reception

Body
copied!<p>I am new to Network Programming, and I am having a problem with some code I've been testing as the basis of a LAN chat program.</p> <p>Server Code:</p> <pre><code>public static void Main() { UdpClient publisher = new UdpClient("230.0.0.1", 8899); UdpClient subscriber = new UdpClient("230.0.0.2", 8800); IPAddress addr = IPAddress.Parse("230.0.0.1"); subscriber.JoinMulticastGroup(addr); Console.WriteLine("Running chat program at 230.0.0.1:8899"); while (true) { IPEndPoint ep = null; byte[] chats = subscriber.Receive(ref ep); string chatstring = Encoding.ASCII.GetString(chats); Console.WriteLine(chatstring); string msg = String.Format(chatstring); byte[] sdata = Encoding.ASCII.GetBytes(msg); publisher.Send(sdata, sdata.Length); System.Threading.Thread.Sleep(500); } } </code></pre> <p>And the client program:</p> <pre><code>static void Main(string[] args) { UdpClient subscriber = new UdpClient("230.0.0.1", 8899); IPAddress addr = IPAddress.Parse("230.0.0.1"); subscriber.JoinMulticastGroup(addr); IPEndPoint ep = null; Thread SendChats = new Thread(Send); SendChats.Start(); while (true) { byte[] receivedbytes = subscriber.Receive(ref ep); string receivedchats = Encoding.ASCII.GetString(receivedbytes); Console.WriteLine(receivedchats); Thread.Sleep(500); } } static void Send() { UdpClient publisher = new UdpClient("230.0.0.2", 8800); while (true) { string msg = Console.ReadLine(); byte[] sdata = Encoding.ASCII.GetBytes(msg); publisher.Send(sdata, sdata.Length); Thread.Sleep(400); } } </code></pre> <p>By my figuring, the server program SHOULD be receiving data from the client, but alas, after a message is typed in and delivered, there is never anything getting through. Am I missing something?</p>
