What is Zero Shell?

Zero shell is a small, portable and redistributable Linux program written for servers and embedded systems for providing network and connectivity services.

Zero shell is not an operating system based service and it totally depends upon a web based graphical user interface.

The users simply has to login to the user interface on the web instead of using a shell to configure and administer the zero shell.

Zero shell can be downloaded from Internet in form of a compact flash image or can be purchased as a live CD. The user can buy the CD or download the flash file and configure or administer it by simply using his web browser.

Its independent nature allows the zero shell to launch itself even from the CD Rom without any kind of installation. The database that contains all the information about zeroshell like settings and data can be stored on the hard disk of the computer.

This information can also be stored in a USB disk and be carried with the zero shell compact disk. The automatic update system of the zero shell lets it download all the updates and security fixes from Internet automatically.

These updates and security patches are stored in the zero shell databases and applied when ever needed. If the latest or newer compact disk already contains these security patches then they would be automatically removed from the database to prevent duplication and ensure consistency.
