Jabber protocol change?

	Hi guys,

	Sorry to bother you again, this is still related to my jabber upgrade 
project.

	So the new server is running jaber14 1.6, the old one was jabber14 1.4. 
My client is actually a Flash applet, we use it to provide a chatroom 
facility for out product. Now the client is failing to connect to the 
new server, I captured the TCP stream, and I am trying to figure out 
what my client is doing wrong -- but since I have no clue about the 
Jabber protocol, i am totally lost.

	The server logs nothing useful. This is all it logged for the failed 
connection:

jabberd14[13239]: [stat] (sessions.localhost): delivered messages 0
jabberd14[13239]: [stat] (sessions.localhost): delivered presences 0
jabberd14[13239]: [stat] (sessions.localhost): delivered iqs 0
jabberd14[13239]: [stat] (sessions.localhost): delivered subscriptions 0

	here is what the malfunctioning stream looks like -- when my client 
connects to Jabber14 1.6 server:

SENT: <?xml version="1.0"?><stream:stream to="foo.askonline.net" 
xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" 
version="1.0" />

SENT: <presence 
to="foo-WritingCenter-1197 <at> conference.localhost/victor-admin"><x 
xmlns="http://jabber.org/protocol/muc" /></presence>

Your client sends presence packet before authenticating.
This is not allowed.

Re: Jabber protocol change?

	What you say makes sense, but if I defer sending the presence, and 
instead try to simply initiate authentication right away, i still get 
the same error:

SENT: <?xml version="1.0"?><stream:stream to="foo.askonline.net" 
xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" 
version="1.0" />

Connection succeeded!

Try looking in server logs for the reason for disconnecting client.
Maybe enable some debug...

Hi Victor,

I guess it should be:

<iq id='log_user_1' to='foo.askonline.net' type='get'><query 
xmlns='jabber:iq:auth'><username>victor</username></query></iq>

(Note the additional to attribute of the <iq/> element.

Regards,
Matthias

Re: Jabber protocol change?

    I will try it, thanks. For now we have reverted to the old Jabber server, but this is clearly not a sustainable solution.
