Jabber Tutorial

Jabber on SDF

Jabber is the former name for the Extensible Messaging and Presence Protocol (XMPP), which is a set of open XML technologies for presence and real-time communication developed by the Jabber open-source community in 1999, formalized by the IETF in 2002-2004, continuously extended through the standards process of the XMPP Standards Foundation, and implemented in a wide variety of software, devices, and Internet services. Jabber service on SDF is run on ejabberd.

Jabber is popularly used as a decentralized instant messaging service. This means that you can create an account on one server such as SDF and talk to users from any other Jabber service. It is also possible to use a transport to communicate with users on other types of instant messaging services as well.

To join an existing conference using Pidgin

By default you will not be notified of activity in conference windows the same way you are when someone talks in a one-to-one chat window. You can change this by going to Tools->Plugins, selecting to configure Message Notification and checking Chat Windows in the "Notify For" section.

You can also use your SDF account to chat with people who have accounts on other Jabber servers. Note that some people might call it `XMPP' instead of `Jabber'. One of the largest Jabber servers is Google Talk: you can chat to GMail/Google Talk users this way without needing a Google account. The Jabber address of those users is the same as their email address.
