1. We will soon require users to register via account.jabber.at and disable In-Band Registration (meaning registration from within the client).

Improved connectivity through firewalls for jabber.at

Dec. 12, 2014, 10:06 a.m. by mati

We have just enabled an additional SRV record that enables jabber.at users to connect via port 443 (what HTTPS typically uses). This should greatly improve connectivity if you are behind a restrictive firewall that blocks "non-standard" ports like port 5222 that Jabber/XMPP uses. We will enable this in a day or so for all other domains as well. ... read more

DIGEST-MD5: Gone for good - No more clear-text passwords!

Nov. 24, 2014, 7:24 p.m. by mati

Sine November 15, we have received only a single complaint from a user that was no longer able to connect to our server and this user wasn't able to name the client. So we've decided that DIGEST-MD5 is gone for good. We will not enable it again. This means that we will enable SCRAM-SHA1 password storage on Saturday, November 29. From then on, all passwords will no longer be stored as clear text passwords!. ... read more

November 15: Deactivation of DIGEST-MD5 authentication

Nov. 11, 2014, 11:53 a.m. by mati

We will disable DIGEST-MD5 for all our domains on Saturday, November 15. DIGEST-MD5 is an old insecure authentication mechanism and the reason we still store passwords in plain text. We don't really know how many users might be affected, so please contact us if you have any problems connecting on or after November 15. We consider this step a trial-run and might enable DIGEST-MD5 again if to many users report (unfixeable) problems. Technical background. DIGEST-MD5 is the original SASL authentication mechanism in the Jabber protocol. ... read more
