I've hit JabberD 2.0 very hard, and very quickly, and not seen any
issues like this. I was running the server on a 2x 2.4Ghz Xeon box with
Red Hat 9 - perhaps the issue they're talking about only happens on
single-proc machines?

Hi Robert!

As this was in the mailing list just a few days ago, I asked this as
well. I think I got the answer or a pointer to something that told me,
that it does not work if the client sends the authentication stanza in
the same TCP packet as the stream start. But I do not know why this
should be a problem. I have not checked if this is really a/the problem.

Happy new year!

Yahoo-t 2.3.0 Released

Happy New Year .... An updated Yahoo-t is now available

This release incorporates many small bugs fixes. The most significant changes are better 
handling in cases of connection timeouts and errors.

In addition, this release of Yahoo-t is designed to be run standalone using the upcoming 
JCR 0.2.1 release. This will create a standalone binary version of the transport. See 
http://jabber.terrapin.com/ for details on JCR. It is expected to be released within a week.

There are still some licensing issues that need to be resolved concerning the Gaim source 
code used in Yahoo-t. Right now, I'm trying to track down the original sources of these 
files to make sure that they are compatible with the GPL license that Yahoo-t is released 
under. More to come on this subject soon.

Reagrds,
Paul

Rob,
  That's excellent, thanks.  Do you have any pointers to writing jabber2
components, or do I just need to dive into the code?
  For what it's worth, if I'm able to write what I want and what I write
isn't complete junk, I'll share it when I'm done.
  Thanks.

Since jabberd2 is stable and out, a component developer HOWTO is really
needed.

Is it possible to make a componnent request only "certain" messages to
be delivered to it... or it all or nothing?

If it is, what are the criterias possible to select the "certain"
messages?

HowTO: Run Jabber Server Behind NAT?

Hello:

I'm trying to run a Jabber server on a box that is behind a DSL Router/Modem
that requires that NAT be turned on.

I have a static IP address, and valid DNS records for said address, but of
course the address is the public interface of the DSL Router/Modem, not
the box on which the jabber server is running.  I have the jabber
ports forwarded to the machine running jabberd (version 1.4.2), but 
jabberd, instead of accepting the packets, keeps trying to forward
them over an s2s link to the "real" server.

Here's a picture:

+------------+                    +-------------------+
| Computer   | < 192.168.0.100    | DSL Router/Modem  | < Public IP Address
| running    +--------------------+     running NAT   +------------- Internet
| jabberd    |                    |                   | jabber.notreal.us
+------------+                    +-------------------+

I've tried lots of stuff, but nothing seems to work.

In short: is there any way to run a public jabber server behind a NAT'ing
firewall?

Thanks,
John S.

jabber2, off-line messages, and timezones

Hello all,
  I've noticed that with the most recently released jabber2 code, off-line
messages are delivered with the timezone information missing, so my client
(actually, I've only tested this with Psi) shows off-line messages as coming in
GMT, 5 hours later than they actually are (I'm in the eastern timezone of the
US).  Has anyone else noticed this?  (that is, is it a problem in my
environment, or is it more widespread?)
  Minor issues like this aside, I'm very pleased with all of the efforts of the
jabber2 team - thank you.

Assuming this is a "quick login", I would note the following:

 - This isn't really any quicker, as the client still has to receive the
   stream response, auth result, etc before it can do anything useful.

 - Its pretty bad form on the part of the client to assume that the
   stream will always be successfully established. And with XMPP making
   error conditions so much more explicit, you really can't afford to
   not be watching for errors every step of the way. I consider your
   client to be broken if its not doing this.

 - jabberd2 takes steps to handle packets that arrived before the stream
   was established - they get queued until the stream is fully open (ie
   the stream response has been returned to the client), then replayed.
   This is a hack, but is needed for quite a few broken clients.
   However, it hasn't been well tested, so there may be a bug there.

No, its all or nothing. You'll get everything the router sees -
including internal session control packets, DNS resolution packets
component discovery packets, etc.

Have you tried adding the hostnames of the jabber server to /etc/hosts on the 
jabber server itself?  That way it should think it is the real server.
