Packet Fence is a Network Access Control solution with world class features and many features beating those provided by expensive commercial alternatives.

Packet Fence is built on Redhat/Fedora Linux and can be built from source and installed on most if not on all of the Linux distributions. Packet Fence is easily configurable with a good GUI although installation takes a bit of a hardwork as it involves installing a lot of other opensource software and tools for it to work like Nessus (Opensource Security Vulnerability Scanner) and Snort (Opensource Intrusion Detection). Packet Fence is now also available as a VMware image (PF ZEN) that can be downloaded from their website. This requires no work (a zero effort installation) and can be operational almost instantly (ideal for testing before deployment).
