Subject: Login failed in windows 8 / IPV4 IPV6
Dear Alex,

I'm using agsxmpp library in C# Projects on windows xp & 7 with openfire for couple of years. Its working properly.
But I have login issue with windows 8 by using the same agsxmpp library.

Observation:
1. In windows 8 system , Both IPv4 and IPv6 are identified and ipv4 is active.
2. I don't find any major differences in wireshark packet capture.

Queries:
1. Is login issue identified in windows 8 and available any patch?
2. Login issue may be raised because of ipv4/v6?

Kindly share your valuable inputs to proceed further..

Thanks

You probably run into the ipv6/ipv4 problem like many others did before. The forums search should help you there.

Alex,

I have downloaded the agsXMPP.dll(1.3.1.0) from http://www.ag-software.net/download-directory/.

Then i added agsXMPP dll into project by using add reference. But login issue does not resolved.

Please find the connection status in debug output as follows.,
Connection ChangedConnecting
Connection ChangedConnected
Connection ChangedSecuring

There is no progress after that.

I have done the packet capture by using wireshark.
please guide me any other details need to be verified with packet capture to resolve the login issue.

Thanks

Please post your Xml log.
When you get the status Connected and Securing this is no ip problem. You are already connected to the server.

Thanks Alex.

Please find the xml as below.,

Connection ChangedConnecting
Connection ChangedConnected

  1. Write Xml : <stream:stream to='testdev.org' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' xml:lang='en'>
  2. Read Xml: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" from="testdev.org" xml:lang="en" version="1.0" id="6db3039b" >
  3. Read Xml: <stream:features xmlns:stream="http://etherx.jabber.org/streams"><starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls" /><mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><mechanism>PLAIN</mechanism><mechanism>ANONYMOUS</mechanism></mechanisms><compression xmlns="http://jabber.org/features/compress"><method>zlib</method></compression><auth xmlns="http://jabber.org/features/iq-auth" /><register xmlns="http://jabber.org/features/iq-register" /></stream:features>
  4. Connection ChangedSecuring
  5. Write Xml : <starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls" />
  6. Read Xml: <proceed xmlns="urn:ietf:params:xml:ns:xmpp-tls" />


Even i have observed that auth request is not triggered.

Thanks

there is a problem with TLS negotiation. Either on the server, or in your software.
Check if you get the certificate validation callback and if you accept the cert. And check your server logs for Tls issues.

Please find the openfire server log for further debugging.,

have you looked at the certificate call back as I suggested?
Have you tried the MiniClient example?
Have you tried the MiniClient example from MatriX?

Sorry for the delay. i was busy with other issues.

I have tried MiniClient sample from MatriX which you suggested. But the result of MiniClient is same request and response which already i have shared the xml. I don't find any other request and response.

i need some more clarity about certificate call back. So that i can go through and share the results.

Thanks

when you look at the MiniClient example you can see the following function:

  1. private void xmppClient_OnValidateCertificate(object sender, CertificateEventArgs e)
  2. {
  3.    // some code here.
  4. }

There the Tls certificate from your server gets validated.

If you add the following code in this function then it will just will accept your certificate, whether its valid or not.

  1. private void xmppClient_OnValidateCertificate(object sender, CertificateEventArgs e)
  2. {
  3.    // always accept cert
  4.    e.AcceptCertificate = true;     
  5. }

If this also does not work then there must a problem with TLS on your server. In this case try to connect without TLS.

  1. xmppClient.StartTls = false;

I have done the changes as suggested in MiniClient like

  1. private void xmppClient_OnValidateCertificate(object sender, CertificateEventArgs e)
  2. {
  3.     // always accept cert
  4.     e.AcceptCertificate = true;
  5.  
  6.     // or let the user validate the certificate
  7.     //ValidateCertificate(e);
  8. }

and
  1. this.xmppClient.StartTls = false;


Result:
  1. SEND: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" to="testdev.org" version="1.0" >
  2. RECV: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" from="testdev.org" id="fc358f0f" xml:lang="en" version="1.0" >
  3. RECV: <stream:features xmlns:stream="http://etherx.jabber.org/streams">
  4.  <starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls" />
  5.  <mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl">
  6.     <mechanism>PLAIN</mechanism>
  7.     <mechanism>ANONYMOUS</mechanism>
  8.  </mechanisms>
  9.  <compression xmlns="http://jabber.org/features/compress">
  10.     <method>zlib</method>
  11.  </compression>
  12.  <auth xmlns="http://jabber.org/features/iq-auth" />
  13.  <register xmlns="http://jabber.org/features/iq-register" />
  14. </stream:features>
  15. SEND: <auth mechanism="PLAIN" xmlns="urn:ietf:params:xml:ns:xmpp-sasl">XXXXX</auth>
  16. RECV: <failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl">
  17.  <not-authorized />
  18. </failure>
  19. SEND: </stream:stream>
  20. RECV: </stream:stream>


But received failed auth response even without TLS. Any idea?

Let check the server settings in mean while.

Thanks

Thanks for your great support.

Thanks
