Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Is it possible to connect to a XMPP server using SASL Anonymous?

I don't see any options to do so.

Is there an update on this? Is this possible?I tried to ovveride the 
OnLoginRequired event and do a Write of the auth xml, but that didn't work.

I have a fork of jabber-net with an implementation of SASL Anonymous.  The fork 
can be found at https://github.com/ffailla/jabber-net.  What is the process for 
submitting patches to jabber-net?  I would be more than happy to prepare a 
patch for submission/review.  Thanks.

I've tried this code linked to in comment 2 but I can't get past the 
authentication stage. My jabber server reports to the logfiles that anonymous 
auth was accepted, but my client just closes the socket

I believe I've narrowed down my issue to the library seemingly sending two auth 
requests only for anonymous auth, like so (from wireshark):

request 1:
<stream:stream xmlns:stream=\"http://etherx.jabber.org/streams\" 
id=\"e4f08436\" xmlns=\"jabber:client\" to=\"uk1.freech.at\" version=\"1.0\">

response 1:
<?xml version='1.0'?>
<stream:stream xmlns='jabber:client' 
xmlns:stream='http://etherx.jabber.org/streams' id='1012300714' 
from='uk1.freech.at' version='1.0' xml:lang='en'>
  <stream:features>
    <starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>
    <mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
      <mechanism>ANONYMOUS</mechanism>
      <mechanism>DIGEST-MD5</mechanism>
      <mechanism>PLAIN</mechanism>
    </mechanisms>
    <register xmlns='http://jabber.org/features/iq-register'/>
  </stream:features>

request 2:
<auth mechanism=\"ANONYMOUS\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\" />

response 2:
<success xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/>

request 3:
<auth mechanism=\"ANONYMOUS\" xmlns=\"urn:ietf:params:xml:ns:xmpp-sasl\" />

response 3:
<?xml version='1.0'?>
<stream:stream xmlns='jabber:client' 
xmlns:stream='http://etherx.jabber.org/streams' id='426829087' from='freech.at' 
xml:lang='en'>

request 4:
<stream:stream xmlns:stream=\"http://etherx.jabber.org/streams\" 
id=\"d85deecc\" xmlns=\"jabber:client\" to=\"uk1.freech.at\" version=\"1.0\">

response 4:
  <stream:error>
    <invalid-namespace xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
  </stream:error>
</stream:stream>

Followed by TCP RST packets closing the connection.

I'm banging my head against a brick wall with this one.. help would be most 
appreciated :-)
