Network Security Toolkit
Network Security Toolkit (NST) is a bootable live CD based on the Fedora distribution. The toolkit was designed to provide easy access to best-of-breed open source network security applications and should run on most x86 platforms.

What we find rather fascinating with NST is that we can transform most x86 systems (Pentium II and above) into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner.
