Zeroshell is a small open-source Linux distribution for servers and embedded systems which aims to provide network services. Its administration relies on a web-based graphical interface; no shell is needed to administer and configure it. Zeroshell is available as Live CD and CompactFlash images, and VMware virtual machines.

Zeroshell can be installed on any IA-32 computer with almost any Ethernet interface. It can also be installed on most embedded devices.
