How To Run Your Own XMPP Server

Because XMPP is a decentralized technology, anyone can run their own server and join the open XMPP network. The most active, popular server software projects are probably ejabberd, Openfire, and Prosody (a full list is at http://xmpp.org/xmpp-software/servers/). Simply download the software of your choice, follow the installation instructions provided with your software, obtain a digital certificate from a certification authority (StartSSL is a popular choice), and make sure to configure your software to allow server-to-server connections. If you have any questions, ask the providers of your server software or join the operators@xmpp.org discussion list.
