Devil-Linux is a distribution which boots and runs completely from CD. The configuration can be saved to a floppy diskette or a USB pen drive. It was originally intended to be a dedicated firewall/router but now Devil-Linux can also be used as a server for many applications. Attaching an optional hard drive is easy, and many network services are included in the distribution.
