IBLS is a compact, easy to use
webserver that you can run from a live CD, even on older hardware. It will
run on a P133 with 32MB RAM, or possibly less. IBLS got its start in the
UK, using Damn Small Linux as a base. It has since been rebuilt from
scratch by an international community of developers. IBLS is modular and
uses its own package management system, designed to run from the CD or from
a hard drive. Although designed to be a server, there are plenty of
packages available to build any type of system.
