Thread: problem with server socket

I created a C# app which runs a thread accepting socket calls on windows 7 port 8888 (also tried 666) but the connection always times out. Connecting to localhost works fine. Anyone experienced the same issues on windows 7?

Obvious question, but have you port forwarded?

Thats not the solution, I have two servers running on the internal network both on that port. But when I only start one and connect with telnet to it having it port fowarded to that pc it still doesnt work

Can you paste some code showing the creation of the socket used for listening?

check this link: a simple socket program.

gv.

Thats the same code where I got it from but adapted a little. Anyway, here is the server socket class.

Code:

    private class AgendaServer
    {
      private TcpListener mServerSocket;

      private AgendaForm mParentForm;

      public AgendaServer(TcpListener serverSocket, AgendaForm parentForm)
      {
        mServerSocket = serverSocket;
        mParentForm = parentForm;
      }

      public void Server()
      {
        mServerSocket.Start(10);

        while (true)
        {                    
          TcpClient client = default(TcpClient);

          client = mServerSocket.AcceptTcpClient();

          byte[] from = new byte[100000];

          NetworkStream nwStream = client.GetStream();
          nwStream.Read(from, 0, from.Length);

          UTF8Encoding enc = new UTF8Encoding();

          string str = enc.GetString(from);

          using (StreamWriter writer = new StreamWriter("agenda.txt"))
          {
            writer.Write(str);
          }

          mParentForm.RefreshAgenda();
        }
      }
    }

I create a Thread which runs AgendaServer.Server and a client sends text to it with this code

Code:

        Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);

        IPAddress ip = IPAddress.Parse(ipstring);

        s.Connect(ip, 666);

        UTF8Encoding enc = new UTF8Encoding();

        string text = "";
        using (StreamReader reader = new StreamReader("agenda.txt"))
        {
          string line;
          while ((line = reader.ReadLine()) != null)
          {
            text += line + "\r\n";
          }
        }

        s.Send(enc.GetBytes(text));

        s.Close();

When creating the TcpListener object are you ensuring you pass IPAddress.Any as one of the arguments?

Code:

TcpListener listener = new TcpListener(new IPEndPoint(IPAddress.Any, 666));

Aaaah that was it! thanks!

You're welcome.
