Hi,

 

I have developed a C# application like this.

 

public static void Main()

{

UdpClient sock = new UdpClient();

      IPEndPoint iep = new IPEndPoint(IPAddress.Parse("10.201.234.112"),
32773);

      int discarded;

      byte[] data =
HexEncoding.GetBytes("000300250000feca676574766f642e636f6de7424d5f313631
3100000e10001505424d5f313631315f776974685f747261696c6f7200000edf090edc05

discarded);

      sock.Send(data, data.Length, iep);

}

 

When I send packets this way, I am getting an exception when I sniff
through Wireshark.

Kindly let me know what might have gone wrong?
