A Fedora remix that gives you ability to limit outgoing traffic using whitelists stored on any web server. Originally intended as a way of preventing test takers from cheating during examinations by forbidding access to network resources other than the e-test itself.
Project consists of Kickstart script used to create the actual Fedora spin with livecd-tools, (X)Dialog GUI to make a process of creating the spin easier, scripts used to control the outgoing network traffic (utilizing iptables firewall and local squid proxy) and PHP whitelist generator.
