Zero Shell is a small, portable and redistributable Linux program written for servers and embedded systems to provide 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 user 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 the internet in the 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 a 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 Zero Shell 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 automatically download all the updates and security fixes from the internet.
These updates and security patches are stored in the Zero Shell databases and applied whenever needed. If the latest compact disk already contains these security patches then they would be automatically removed from the database to prevent duplication and to ensure consistency.
