in my typical love and hate relationship with opensource  (aka open sore) i stumbled over SASL induced configuration pains again today. To cut a long story short, just disable DIGEST-MD5 sasl out on the openfire jabber server and immediatly xmpp4r works like a charm for me.

How to disable digest md5 on Openfire? Not so easy to find out and in a beautiful amateuristic way lots of the advice you find is actually plain wrong.

Put this into your openfire.xml:

<sasl><mechs>PLAIN</mechs></sasl> 
<!-- but put it inside the <jive>...</jive> tags somewhere --> 

, because when you know the name of the right openfire property, and are able to read(in openfire.xml):

    This file stores bootstrap properties needed by Openfire.
    Property names must be in the format: "prop.name.is.blah=value"
    That will be stored as:
        <prop>
            <name>
                <is>
                    <blah>value</blah>
                </is>
            </name>
        </prop>

,then you easily know that <sasl><mechanisms>….</mechanisms></sasl> is bogus.

you usually find your openfire.xml at ${OPENFIRE_HOME}/conf/openfire.xml. and you must restart the the server afterwards, like /etc/init.d/openfire restart.

there is another option, like making the xmpp4r implementation don’t even try to use the digest-md5 mechanism which the openfire server offers. Just disabling DIGEST-Md5 acceptance at /opt/local/lib/ruby/gems/1.8/gems/xmpp4r-0.3.2/lib/xmpp4r/client.rb:108 in Jabber::Client.auth does work, but i will try to get it implemented a littel more selective before posting a xmpp4r fix here. Who knows, there even might be two SASL DIGEST-MD5 implementations on this planet which actually do match? i doubt it, an even then, i don’t care. vote for alt.source.sasl-must-die-die-die and

have fun

the title was actually quoted from the the Amazon Web Services Blog. That post reports on a new option of running a version of the Wowza Flash Streaming Video server as a virtualized AMI instance  from insides the Amazon EC2 cloud.

What this all means? You get a real cheap way to build you’re own streaming network. For private videos YouTube will to the trick of serving your private holiday videos to the fans and you don’t have to bother for neither price nor capacities. But with such a thing as a Wowza server on EC2 you can now build your very own YouTube on demand. And it’s running on small pockets too. For only 5$ a month you get the right to do so and beyond that you pay per-hour and bandwith.

But even besides the economics, Wowza brings more to the party. It is a real good piece of software it seems. I worked with it just end of last years and all operations where smooth. Before Wowza choosing a streaming server sometimes to me felt more like “die Wahl zwischen Pest und Cholera”(or Hobson’s choice as i learned). I worked with Wowza last year and it was breeze of fresh air. I think i read somewhere it was written by some old SGI dudes. Ah, good old times, but that is another story(Personal Iris anyone?)

Adobe, the original? Expensive, old-school. heavy. not sexy. Red5 Open Source? Good luck i wish. I never had. Quicktime? Don’t know about QTSS but the DSS variant of it failed on me badly whenever i needed it and on top of that it uses PERL! to serve its admin HTML pages, uha, shudder.

Some fellows became even so desperate as to start recoding things from scratch and try writting an RTMP* server in Erlang. As i said elsewhere, Erlang, power- and beautiful concepts, but such an ugly language. Again, good luck i wish. If someone might want to spent a couple of month on trying to combine Erlang concepts and ruby language on writing a scalable stand-in replacement for the proprietary FLash streaming video server solutions than please give me call. Would be a nice project.

Matt Aimonetti released a 1.0.0 version of his googlecharts gem which includes my URI bugfix i blogged about earlier. Me haven’t had so many opensource contributions yet, feels good though.
