Trying to do Client-server TCP connection in web player...

Hello Long story short.. I am working on a Client-Server networking solution. I have a dedicated server with the proper ports open and listening for connections. My Unity project connects to that server and its port, and begins sending data.

Works fine! Except....

When I try to run it in the webplayer.... I get this:

Code (csharp):

1. SecurityException: Unable to connect, as no valid crossdomain policy was found
2. System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32 error, Boolean requireSocketPolicyFile)
3. System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy)
4. System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP)
5. System.Net.Sockets.TcpClient.Connect (System.Net.IPEndPoint remote_end_point)

Here is the code for my client:

Code (csharp):

1. public class ClientTest : MonoBehaviour {
2.     BinaryWriter so;
3.     // Use this for initialization
4.     void Start () {
5.         TcpClient client = new TcpClient();
6.  
7.         IPEndPoint serverEndPoint = new IPEndPoint(IPAddress.Parse("-Censored-IP-"), 5en50r3d p0r1);
8.  
9.         client.Connect(serverEndPoint);
10.  
11.         NetworkStream clientStream = client.GetStream();
12.        
13.         while (!clientStream.CanRead || !clientStream.CanWrite)
14.         {
15.             Debug.Log("Spinning until can write");
16.         }
17.         so = new BinaryWriter(clientStream);
18.    
19.         so.Write("Blah blah blah");
20.         so.Flush();
21.    
22.    
23.     }
24. }
25.  

How might I configure my code to resolve these cross-domain issues, and enable web-player support for my networking?

 

You need to run a socket policy server on the server host also, read up on this http://unity3d.com/support/documentation/Manual/Security Sandbox.html

This applies to you even if you don't use the built-in unity networking and just use the raw System.Net.Sockets API

 

Thank you thank you THANKYOU Fholm! Works like a charm!

 

No problem
