resources), the resource adds a useful amount of specificity. the resource is optional although XMPP allows a single JID to be connected to the server from multiple machines (i.e. In following example, “username” is the username, “” is the hostname, and “/office” is the resource. The resource is optional, and is often safely omitted or ignored for most users. It often looks like an email and contains the username that identifies a specific user on a server, the hostname that identifies the server, and a resource that identifies where a given user is logged in from. The JID or “Jabber ID,” is the unique identifier for a user in the XMPP network. Though you can successfully run an XMPP server with only a passing familiarity of the way the XMPP network and system works, understanding the following basic concepts will be helpful: Once you’ve completed these requirements, we can begin with the installation process. We also assume you are connected to your Linode via SSH as root. Setting Up and Securing a Compute Instance guide, and now have an up to date instance of the Ubuntu Jaunty operating system. This installation process assumes that you have a working installation of Ubuntu 9.04 (Jaunty), have followed the steps in the Ejabberd servers are believed to be the backbone for some of the largest Jabber servers running now. However, it is incredibly robust and can scale to support incredibly heavy loads. Ejabberd can be considered “heavyweight” by critics, because of the requirements of the Erlang run-times.

XMPP standards, ejabberd is a great choice for a multi-purpose XMPP server. With a web-based interface, and broad support for It is extensible, flexible and very high performance. Ejabberd is a Jabber daemon written in the Erlang programming language.
