Unable to connect from remote machine
c#, connection, tcpclient, tcplistener
Solution
You need to set it to accept connections from any IP, there is an IPAddress overload function for this:
System.Net.IPAddress.Any
use it instead of 127.0.0.1 and it will fix your problem.
Problem
I have some kind of problem and I can't check this at home if its working or not. Here is the code ``` using System; using System.Net; using System.Net.Sockets; using System.Threading; using System.IO; using System.Net.Security; class Program { private static IPAddress ipAddress = IPAddress.Parse("127.0.0.1"); private static int port = 6000; private static string data = null; static void Main(string[] args) { Thread thread = new Thread(new ThreadStart(receiveThread)); thread.Start(); Console.ReadKey(); } public static void receiveThread() { while (true) { TcpListener tcpListener = new TcpListener(ipAddress, port); tcpListener.Start(); Console.WriteLine("Waiting for connection..."); TcpClient tcpClient = tcpListener.AcceptTcpClient(); Console.WriteLine("Connected with {0}", tcpClient.Client.RemoteEndPoint); while (!(tcpClient.Client.Poll(20, SelectMode.SelectRead))) { NetworkStream networkStream = tcpClient.GetStream(); StreamReader streamReader = new StreamReader(networkStream); data = streamReader.ReadLine(); if(data != null) Console.WriteLine("Received message: {0}", data); } Console.WriteLine("Dissconnected...\n"); tcpListener.Stop(); } } } ``` I have a simple program as well to connect to this and then send a string with data. It works fine on localhost but there is a problem when I'm trying to connect with a different coputer. I even turned off the firewall on my PC and router, as I did on my friend's laptop. Every time I have tried to connect, his computer refused connection. Maybe I'm doing something wrong? Of course, `ipAddress` is a local address now since it's only working with that at the moment. Any suggestions what to do?
