Socket problem in 2008

[paulyc]

Hello,

I am attempting to write a socket program, in C#.
I am able to creat the socket, and use Ethereal to view the Tx and the Rx from the target. Ethereal reports Rx data, but I am unable to see any.

The highlights are as follows:

Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); //ok
s.Connect(IPs[0], port); //ok
endpoint = new IPEndPoint(IPAddress.Parse(host), port);
s.Bind(endpoint); //ok
s.SendTo(send_bytes, Tx_Length, SocketFlags.None, endpoint);

//ethereal reports tx and rx bytes!

//the following reports no data (exception generated)
new_socket.Receive(Rx_Packets, Rx_Packets.Length, 0);

//I also tried a thread that catches everything
int test = 0;
do
{
test = global_socket.Available;


} while (test < 1);

if (test > 0)
global_socket.Receive(Rx_Packets_Thread, Rx_Packets_Thread.Length, 0);

//no data

Any thoughts?
