How to Set Up a Jabber Server

Post date: April 12, 2005, 16:04 Category: Software Views: 6466 Comments
Tutorial quote: Unless you have been living under a rock for the past few years, you must have heard about instant messaging and how it has changed the world of communications over the Internet. According to http://www.webopedia.com, Instant Messaging (IM) is a service that alerts users when their friends or colleagues are on line and allows them to communicate in real time through private online chat areas. Two of the most popular IM services are AOL Instant Messenger (AIM) and MSN Messenger. Unfortunately, most of the publicly available servers use proprietary protocols that only allow you to communicate with users on the same system. These systems are not compatible with each other and can't be accessed from other clients.

Jabber is an open source implementation of the IM server that aims to change this. It uses streaming XML protocols that are free, open, and public. These protocols have been formalized by the Internet Engineering Task Force (IETF) as the approved instant messaging and presence technology under the name of XMPP. The first Jabber technologies were developed in 1998 by Jeremie Miller and is now used on thousands of servers world-wide to enable millions of users to communicate with each other.

The biggest advantage of the Jabber server when compared with commercial IM servers is that, since it is open source, anyone can run a Jabber server and it can be restricted to a specific community like a company work force or a group of friends. In this article, I will document the steps I took to set up a Jabber server and how I managed to overcome the difficulties I faced. Hopefully this will make it easier for you to set up your own Jabber server.
