TcpClient

Gday Guys/Girls,

I am trying to create a TCP server and clients. I want the server to be able to handle multiple active clients 24/7 (approx 10-15 clients, possibly more). The server will send a string to the client and the client runs a command based on the string sent. I have a basic TCP Server and Client. The TCP Server only accepts 1 client at a time, could someone please provide and example or modify my code to allow the server to allow multiple clients. Also could someone provide an example on how to make the server send the command and the client wait for the command as I can only get it to work the other way around. Any help is greatly appreciated.

Also, the client will need to stay connected so that the server can send commands at any time.

Matt


SERVER CODE

                TCPListener myList = new TcpListener(ipAd, 8001);
                myList.Start();
                Console.WriteLine("The server is running at port 8001...");

                Console.WriteLine("Waiting for a connection");
               // Connection();
               // Connection();
                Socket s = myList.AcceptSocket();
                Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);

                for (int i = 0; i < k; i++)
                {
                    command = command + Convert.ToChar(b[i]);
                }
                Console.WriteLine(command);

                s.Send(asen.GetBytes("String Recievced"));
                Console.WriteLine("Sent Acknowledgement");
                s.Close();
                myList.Stop();
                Console.ReadLine();
            }

            catch(Exception ex)
            {
