    copied!<p>I want to create a chat application that uses Ejabberd as the server. I setup the ejabberd on my laptop Ubuntu 12.04 and port forward to my public ip. I try to use Pidgin(Ubuntu), Adium(MacOS), IM+(Andriod, IOS). All of them can connect and chat with each other.</p> <p>However, when I follow the tutorial here <a href="http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-xmpp-integration/" rel="nofollow">http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-xmpp-integration/</a> to build my own chat app. I got a number of issues that cant let me chat with other accounts.</p> <p>Here are the messages sent and received:</p> <pre><code>2012-07-19 11:59:59:749 XMPPStream[49107:403] RosterController: awakeFromNib 2012-07-19 11:59:59:973 XMPPStream[49107:403] AppDelegate: applicationDidFinishLaunching: 2012-07-19 12:00:06:460 XMPPStream[49107:4603] SEND: &lt;?xml version='1.0'?&gt; 2012-07-19 12:00:06:460 XMPPStream[49107:4603] SEND: &lt;stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' to='xxx.xxx.xxx.xxx'&gt; 2012-07-19 12:00:06:464 XMPPStream[49107:4603] RECV: &lt;stream:stream xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" id="1582664547" from="xxx.xxx.xxx.xxx" version="1.0" stream:lang="en"/&gt; 2012-07-19 12:00:06:465 XMPPStream[49107:4603] RECV: &lt;stream:features xmlns:stream="http://etherx.jabber.org/streams"&gt;&lt;starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/&gt;&lt;mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl"&gt;&lt;mechanism&gt;PLAIN&lt;/mechanism&gt;&lt;mechanism&gt;DIGEST-MD5&lt;/mechanism&gt;&lt;mechanism&gt;SCRAM-SHA-1&lt;/mechanism&gt;&lt;/mechanisms&gt;&lt;c xmlns="http://jabber.org/protocol/caps" hash="sha-1" node="http://www.process-one.net/en/ejabberd/" ver="wwrSvLFOLzC92POh074kJuEqYxE="/&gt;&lt;register xmlns="http://jabber.org/features/iq-register"/&gt;&lt;/stream:features&gt; 2012-07-19 12:00:06:465 XMPPStream[49107:403] RosterController: xmppStreamDidConnect: 2012-07-19 12:00:06:466 XMPPStream[49107:403] SEND: &lt;auth xmlns="urn:ietf:params:xml:ns:xmpp-sasl" mechanism="DIGEST-MD5"/&gt; 2012-07-19 12:00:06:468 XMPPStream[49107:3e0b] RECV: &lt;challenge xmlns="urn:ietf:params:xml:ns:xmpp-sasl"&gt;bm9uY2U9IjIxNTYzMTM4ODEiLHFvcD0iYXV0aCIsY2hhcnNldD11dGYtOCxhbGdvcml0aG09bWQ1LXNlc3M=&lt;/challenge&gt; 2012-07-19 12:00:06:468 XMPPStream[49107:3e0b] SEND: &lt;response xmlns="urn:ietf:params:xml:ns:xmpp-sasl"&gt;dXNlcm5hbWU9Imt3ZWluZXIxIixyZWFsbT0iMjAzLjIwNS4xMC4xMjciLG5vbmNlPSIyMTU2MzEzODgxIixjbm9uY2U9Ijg1RUU5MTczLTQ0RTEtNDNDMS1CNzFBLTY3OEE5NTQ2MjU1MiIsbmM9MDAwMDAwMDEscW9wPWF1dGgsZGlnZXN0LXVyaT0ieG1wcC8yMDMuMjA1LjEwLjEyNyIscmVzcG9uc2U9NzMwZWZjNzUxOWIwNzNiNDEzMGU0NjFjMmVmMjliNmIsY2hhcnNldD11dGYtOA==&lt;/response&gt; 2012-07-19 12:00:06:502 XMPPStream[49107:4603] RECV: &lt;challenge xmlns="urn:ietf:params:xml:ns:xmpp-sasl"&gt;cnNwYXV0aD00YzRjMDk4ZGJhYjk2NmNiMTg3MzVhOTMyYTZhMDkxYw==&lt;/challenge&gt; 2012-07-19 12:00:06:502 XMPPStream[49107:4603] SEND: &lt;response xmlns="urn:ietf:params:xml:ns:xmpp-sasl"/&gt; 2012-07-19 12:00:06:854 XMPPStream[49107:4603] RECV: &lt;success xmlns="urn:ietf:params:xml:ns:xmpp-sasl"/&gt; 2012-07-19 12:00:06:854 XMPPStream[49107:4603] SEND: &lt;stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' to='xxx.xxx.xxx.xxx'&gt; </code></pre> <p>Here are what I observed:</p> <ul> <li>When I turn off the ejabberd server, the client app stops working. This mean it tried to connect to the server.</li> <li>On Android, Ubuntu, and MacOS, everytime I login it ask for accepting a certificate. But I dont see it on MY iOs app.</li> <li>It seems that after success, it renegotiates and doesnt receive any response.</li> <li>On the web admin of ejabberd, I dont see any online user. However, I see request is coming in the log. What documents and steps should I follow to debug XMPP application on iOS?</li> </ul> <p>I'm using XCode 4.3.2 iOS 5.1 Ejabberd 2.1.11 on Ubuntu (Linux 32 bits). I tried to debug and google for 2 days but no clue</p>
