Hi, I have a question with signalr, i have a connection of n clients whit a external server, i want use signalr like a kind MIM(Man in the Middle), is posible that my signal server establish a connection whit the external server ??
In this post they explain how to connect to signalR from different clients, the last one is a console application. Use that code in your man in the middle server
Hello I saw the example but this does not solve my problem, I have to connect to an ip and a port, not url address, I do this through socket in a winform, but i want change to SignalR and ASP.Net
string url = "http://localhost:8089";
using (WebApp.Start(url))
{
Console.WriteLine("Server running on {0}", url);
it is ip + port,
Please check again, I think it is what you want.
Best regard
Cathy

After test the example, still do not work for my, I think I have to explain myself better.
I have an application (winform), which does the server function, Of which I will receive information
Code:
public partial class Form1 : Form
{
//library created for my to open a server socket tcp/ip over a given port
WinSockServer.WinSockServer server = new WinSockServer.WinSockServer();
delegate void SetTextCallback(string text);
public Form1()
{
InitializeComponent();
server.NuevaConexion += new WinSockServer.WinSockServer.NuevaConexionEventHandler(server_NuevaConexion);
server.DatosRecibidos += new WinSockServer.WinSockServer.DatosRecibidosEventHandler(server_DatosRecibidos);
server.ConexionTerminada += new WinSockServer.WinSockServer.ConexionTerminadaEventHandler(server_ConexionTerminada);
server.PuertoDeEscucha = "5002"; //Listening port
server.Escuchar(); //I opened the connection here and wait the client connection
}
When I use in the SignalR project the method to connect a external server
var hubconn = new HubConnection("http://localhost:5002");
hubconn.Start().Wait();
the connection is ok, but when I try to send something from the server application(winform) i receive this exception
The server has committed a protocol violation. Section=ResponseStatusLine
en System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
en System.Net.Http.HttpClientHandler.GetResponseCallback(IAsyncResult ar)
I think it's the headline http in the HubConnection and what I'm using in the server application one tcp/ip server socket

Hi alexeirojas87
You said you want to t to an ip and a port, not url address.
In the following link provided by JBetancourt.
https://damienbod.com/2013/11/01/signalr-messaging-with-console-server-and-client-web-client-wpf-client/
See the following code Running in Main
string url = "http://localhost:8089"; using (WebApp.Start(url)) { Console.WriteLine("Server running on {0}", url);it is ip + port,
Please check again, I think it is what you want.

hello,
After test the example, still do not work for my, I think I have to explain myself better.
I have an application (winform), which does the server function, Of which I will receive information
Code:
public partial class Form1 : Form
{
//library created for my to open a server socket tcp/ip over a given port
WinSockServer.WinSockServer server = new WinSockServer.WinSockServer();
delegate void SetTextCallback(string text);
public Form1()
{
InitializeComponent();
server.NuevaConexion += new WinSockServer.WinSockServer.NuevaConexionEventHandler(server_NuevaConexion);
server.DatosRecibidos += new WinSockServer.WinSockServer.DatosRecibidosEventHandler(server_DatosRecibidos);
server.ConexionTerminada += new WinSockServer.WinSockServer.ConexionTerminadaEventHandler(server_ConexionTerminada);
server.PuertoDeEscucha = "5002"; //Listening port
server.Escuchar(); //I opened the connection here and wait the client connection
}
void server_ConexionTerminada(System.Net.IPEndPoint IDTerminal)
{
SetText("Se desconecto:" + IDTerminal.Address.ToString() + "/r/n");
}
void server_DatosRecibidos(System.Net.IPEndPoint IDTerminal)
{
String datosR = server.ObtenerDatos(IDTerminal);
SetText(datosR + "/r/n");
}
void server_NuevaConexion(System.Net.IPEndPoint IDTerminal)
{
SetText("Se conecto:" + IDTerminal.Address.ToString() + "/r/n");
}
private void SetText(string text)
{
if (this.textBox1.InvokeRequired)
{
SetTextCallback d = new SetTextCallback(SetText);
this.Invoke(d, new object[] { text });
}
else
{
this.textBox1.Text = this.textBox1.Text + text;
}
}
private void button1_Click(object sender, EventArgs e)
{
server.EnviarDatos(textBox2.Text);
}
}
When I use in the SignalR project the method to connect a external server
var hubconn = new HubConnection("http://localhost:5002");
hubconn.Start().Wait();
the connection is ok, but when I try to send something from the server application(winform) i receive this exception
