30-minute Practical Linux Project: XMPP Chat Server Setup, Start to Finish
Table of contents is in the description.
This is a 30-minute course that covers setting up an XMPP (jabber) chat server, for chatting with friends. For even more fun, consider allowing open registration, and meet interesting new people!
What's XMPP/Jabber? If you're old: it's like IRC or AOL Instant Messenger. If you're young: it's like real-time twitter, with no character limits!
Requirements: an Internet-accessible server (with an Internet-routable IP address). A $5 VPS from http://www.vultr.com/?ref=6867089 or http://www.digitalocean.com/?refcode=... is just fine (referral code in the link).
