Login information in packages

no_email@example.com (Esofter) — Mon, 06 Sep 2010 18:42:13 GMT

Usually xmpp protocol working:

1. Autorize on server and get sessionID
2. Sending/reciving packages
3. Close connection.

Is it possible not use client-server, sending packages on some port, and reciving from another? And login information will be pass in each package.

Thank you/

Re: what is best solution to check if myUser joins to the room?

no_email@example.com (Alex) — Sat, 28 Aug 2010 15:07:36 GMT

After success you should get presence packets which includes also your own presence.
On failure you should get an presence of type error.

See also the examples here:

how can I check if JoinRoom Works Correctly and I am in the room now?

   MucManager mucManager = new MucManager(_Connection);
      agsXMPP.Jid aRoom = new agsXMPP.Jid(roomName);
      //OnPresenceWaitHandle.WaitOne();
      if (password == string.Empty)
      mucManager.JoinRoom(aRoom, UserJid.Bare, true);
      else
      mucManager.JoinRoom(aRoom, UserJid.Bare, password, true);

Re: XMPP Packet size

no_email@example.com (Alex) — Wed, 18 Aug 2010 09:47:18 GMT

as I said before the max stanza size depends on the server configuration. agsXMPPand MatriX don't split stanzas automatically. There should be an extension for splitting stanzas at: http://xmpp.org/extensions/all.shtml

I use OpenFire. it Supports MaxUsers in the panel but when I request the configuration it doesnt show this feature.
you mean OpenFire maybe didnt support to show it to me by xmpp request??

Re: get more room features

no_email@example.com (Alex) — Wed, 18 Aug 2010 09:30:23 GMT

when you create a new room and request the configuration form you will see all features which your server in the current configuration supports.
The available features depend on the server software you are using and its configuration.

Hi Alex,

As you said, that there's no max. packet size on XMPP specification. Does that mean if I send a chat message with 1.024.000.000 character ( 1 MB ), it would be sent as 1 message ? Or will it be auto-split to several messages by the library ( i.e smack ) ?

If it would be sent as 1 big message, would it be possible to have 'auto-split' facility ? Just like sms, where one sms is max 160 characters. Whenever someone write more than 160 characters, it would be splitted to more than 1 sms, and reconstructed again on the receiver side.

Thanks Alex.

Re: XMPP Packet size

no_email@example.com (Alex) — Sat, 14 Aug 2010 10:36:26 GMT

no, in XMPP this is the max. stanza size.

.......
or
......
or
...

servers count the complete stanza, not the body. Because the stanza could contain unlimited additional tags.

here is a snippet from my ejabberd config:
{5222, ejabberd_c2s, [ {certfile, "D:\\var\\ejabberd\\certs\\ag-software.de.pem"}, starttls, {access, c2s}, {shaper, c2s_shaper}, {max_stanza_size, 65536} ]},
max. stanza size for client connections is here 65536 bytes.

Re: XMPP Packet size

no_email@example.com (cf0rum) — Sat, 14 Aug 2010 10:29:09 GMT

Hi Alex,

Did you refer to packet size ( TCP/IP packet ) or message size ? I've just checked with one of the XMPP Server, yes it is possible
to define maximum message size, which is the maximum data after the body tag.

But I didn't see anything about packet size. Probably this is on the lower level, network or transport layer, which is defined by TCP/IP protocol ?

Thanks, Alex.

Re: XmppComponentConnection with sample server

no_email@example.com (Alex) — Sat, 14 Aug 2010 09:06:58 GMT

you need a listening socket which accepts components and need to add the component protocol also on the server side. Which is only authentication and routing.

XMPP Packet size

no_email@example.com (cf0rum) — Sat, 14 Aug 2010 03:10:11 GMT

Hi everyone,

I've been trying to find out how to define block size for XMPP Packet.

I've tried with Spark and Pidgin ( XMPP client ), both of them don't offer this feature.

I've tried to browse XMPP library as well ( like Smack ), but I couldn't find in the API, how to define block-size.
But I could see in XEP 0047 (In-Band Bytestreams) that it is possible to define block-size.
The problem is XEP-0047 is a client only protocol, and it's for transferring binary data.

Is there a way that I can define maximum block-size in XMPP protocol, and which client API can I use ?

Thanks in advance.

the server was right, and other servers should not allow you to send presence before bind as well. Some other servers are more fault tolerant.

you are sending presence before the resource bind is finished. Can you try to send your presence later? After the OnBind event?

can you please post a better Xml log. It looks like the packets are not in correct order.
1.3.0.2 should login with SCRAM-SHA-1 which is also not the case in your log.

jabber.org runs M-Link. The M-Link servers sends XMPP pings, when you don't respond to thenm you get disconnected which is fine, because according to the XMPP RFCs you have to respond to every Iq. 1.3.0.3 automatically replies to the pings when AutoReplyToPing is true.

btw, Just uploaded 1.3.0.3

Unexspected disconnect on jabber.org

no_email@example.com (martinbach) — Thu, 12 Aug 2010 13:56:05 GMT

Hi Alex,

my app disconnects unexspected short after a successful login on jabber.org.

I tried other ejabbered based server (eg. jwchat.org or 12jabber.com) and my local ejabberd server.
Then I tried tigase based and openfire based servers and my local servers.
All of them behave ok. But with jabber.org I get:

<stream:error xmlns:stream="http://etherx.jabber.org/streams">
<not-authorized xmlns="urn:ietf:params:xml:ns:xmpp-streams" />
</stream:error>

I tied psi and spark against jabber.org to test my accounts, they work,
then I tried the Matrix 1.3.0.2 still the stream error.

Do you have an idea for that bahavior ? Thanks for your help.
