Subject: Problem connecting to server locally
Good evening,

I have just started working with agsXMPP recently and started learning with this tutorial:
http://www.codeproject.com/Articles/21267/Creating-a-Jabbe…

Having downloaded the sample file, it works perfectly fine with these parameters when connecting to an online jabber server, fex. jabber.de

  1. Jid jidSender = new Jid("username@jabber.de");
  2. XmppClientConnection xmpp = new XmppClientConnection();
  3. xmpp.Server = "jabber.de";
  4. xmpp.Username = "username";
  5. xmpp.Password = "Passwort";
  6. string Password = "Passwort"; // is to be used later in the listing
  7. xmpp.AutoResolveConnectServer = false;
  8. xmpp.ConnectServer = "85.214.196.40";

However, when I try to use my local ejabberd server, it does not connect properly:

  1. Jid jidSender = new Jid("123@hapi");
  2. XmppClientConnection xmpp = new XmppClientConnection();
  3. xmpp.Server = "hapi";
  4. xmpp.Username = "123";
  5. xmpp.Password = "Passwort";
  6. string Password = "Passwort";
  7. xmpp.AutoResolveConnectServer = false;
  8. xmpp.ConnectServer = "127.0.0.1";

Apart from the code you see above I have not changed anything in the listing from TheCodeProject.

When executing the code, XmppClientConnection xmpp.ConnectionState is set to "Connecting" and xmpp.Authenticated is "false".

Using Psi to connect to my local server, I had to modify the hosts file to enable the programme to resolve the pc name "hapi" or "localhost" to the right ip address... But for Psi, connecting with the credentials works now. Still I got these issues with the code above.
Is there anything I am missing out on??

Thanks in advance,
Michael_Heribert

are you sure that your ejabberd listens on 127.0.0.1? And not on another network interface? Maybe your local v6 address?
Your code looks fine.

Thank you for your quick reply!

I think it should listen on 127.0.0.1:5222, at least testing with telnet worked. And Psi could connect with these parameters. Maybe there is something else blocking the connection? I tried turning off the windows firewall, but it didn't work either.

This is the complete programme:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Text;
  4. using agsXMPP;
  5. using agsXMPP.protocol.client;
  6. using agsXMPP.Collections;
  7. using agsXMPP.protocol.iq.roster;
  8. using System.Threading;

  19.             XmppClientConnection xmpp = new XmppClientConnection();
  20.             xmpp.Server = "hapi";
  21.             xmpp.Port = 5222;

Did you check if there is any XML flow between the client and the server? Look at the send and receive XML events.

I finally found the reason for this issue:

I was developing on my laptop which is using Windows 10. Now that I could try it on my main pc, running Windows 7, it worked...

Thanks for your help though,

there still must be a reason why it did not work on W10. It should work fine there as well.

Sorry for hijacking your question. Could I ask you which file you got that code from? I've been trying to start up my own client but am getting nowhere. Thanks

browse our websites for MatriX and agsXMPP and you will find this code.
