Is it possible to get the client's referrer domain name? I used source: http://www.codeproject.com/Articles/1415/Introduction-to-TCP-client-server-in-C
Example codes are below:
Server Program
use ip: 172.21.5.99 (server1.com, server2.com, server3.com)
using System;
using System.Text;
using System.Net;
using System.Net.Sockets;
public class serv {
public static void Main() {
try {
IPAddress ipAd = IPAddress.Any;
// use local m/c IP address, and
// use the same in the client
/* Initializes the Listener */
TcpListener myList=new TcpListener(ipAd,8001);
/* Start Listeneting at the specified port */
myList.Start();
Console.WriteLine("The server is running at port 8001...");
Console.WriteLine("The local End point is :" +
myList.LocalEndpoint );
Console.WriteLine("Waiting for a connection.....");
Socket s=myList.AcceptSocket();
Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);
byte[] b=new byte[100];
int k=s.Receive(b);
Console.WriteLine("Recieved...");
for (int i=0;i<k;i++)
Console.Write(Convert.ToChar(b[i]));
ASCIIEncoding asen=new ASCIIEncoding();
s.Send(asen.GetBytes("The string was recieved by the server."));
Console.WriteLine("\nSent Acknowledgement");
/* clean up */
s.Close();
myList.Stop();
}
catch (Exception e) {
Console.WriteLine("Error..... " + e.StackTrace);
}
}
}
/* Client Program */ use ip 231.21.5.1
using System;
using System.IO;
using System.Net;
using System.Text;
using System.Net.Sockets;
public class clnt {
public static void Main() {
Random rnd = new Random();
int rand = rnd.Next(1, 4);
try {
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting.....");
if (rand == 1)
tcpclnt.Connect("server1.com",8001);
if (rand == 2)
tcpclnt.Connect("server2.com",8001);
if (rand == 3)
tcpclnt.Connect("server3.com",8001);
// use the ipaddress as in the server program but random hostname
Console.WriteLine("Connected");
Console.Write("Enter the string to be transmitted : ");
String str=Console.ReadLine();
Stream stm = tcpclnt.GetStream();
ASCIIEncoding asen= new ASCIIEncoding();
byte[] ba=asen.GetBytes(str);
Console.WriteLine("Transmitting.....");
stm.Write(ba,0,ba.Length);
byte[] bb=new byte[100];
int k=stm.Read(bb,0,100);
for (int i=0;i<k;i++)
Console.Write(Convert.ToChar(bb[i]));
tcpclnt.Close();
}
catch (Exception e) {
Console.WriteLine("Error..... " + e.StackTrace);
}
}
}
My point is, let see if there are 3 domains (server1.com, server2.com, server3.com) are BINDED to 172.21.5.99, how to get which domain is the client connected with?
Wanting to do like below:
Assume client's rand is 1, result in the server-side will be :
The server is running at port 8001...
Waiting for a connection.....
Connection accepted from 231.21.5.1 through our server1.com.
Assume client's rand is 2, result in the server-side will be :
The server is running at port 8001...
Waiting for a connection.....
Connection accepted from 231.21.5.1 through our server2.com.
Assume client's rand is 3, result in the server-side will be :
The server is running at port 8001...
Waiting for a connection.....
Connection accepted from 231.21.5.1 through our server3.com.
Is it possible to do so? Im stuck here.
