Im have a lab-environment in VMware with a WS2008R2-server and a W7-client. Im trying to broadcast a WCF-service-address from the server and receive this in the client. Im using System.Net.Sockets in C# .NET and I can successfuly send data from the server. I looks okay with WinDump at least. But when I try to receive this on the client it fails. I cant understand where the problem is..? The client can communicate with the server in other ways and with my WCF-service if I manually enter its address. I have turned of my firewalls in the lab-environment just in case.
[Update]
I checked WinDump on my client-vm and the same udp-message showes up here as well so it seem to be able to receive the broadcast. But why arent the ReceieveFrom-method returning anything? Have I setup the client socket wrong? Should it bind to the Any-address or to its local ip? Neither works...
[/Update]
Heres the server-code:
public static class MulticastServer
{
static Socket socket;
static IPEndPoint ep = new IPEndPoint(IPAddress.Broadcast, 9050);
public static void Open()
{
socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, true);
}
public static void Send(string message)
{
socket.SendTo(Encoding.ASCII.GetBytes(message), ep);
}
public static void Close()
{
socket.Close();
}
}
And the client:
public static class MulticastClient
{
public static string ReceiveOne()
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
IPEndPoint ep = new IPEndPoint(IPAddress.Any, 9050);
socket.Bind(ep);
byte[] data = new byte[1024];
EndPoint e = (EndPoint)ep;
int i = socket.ReceiveFrom(data, ref e);
socket.Close();
return Encoding.ASCII.GetString(data, 0, i);
}
}
