cPanel – Web Hosting Application

Functional overview

cPanel (control panel) is a graphical web-based management tool, designed to make administration of web sites as easy as possible. cPanel handles all aspects of website administration. It is designed for use by commercial web hosting services.

Resellers get access to a part of cPanel called WebHost Manager (often abbreviated WHM), which is a tool to add new users into the system, set various restrictions and monitor account usage. The root administrator has access to a more powerful version of WebHost Manager which can perform common system administration tasks.

cPanel is designed for the end users of your system and allows them to control everything from adding / removing email accounts to administering MySQL databases. For a comprehensive list of cPanel features including screen shots, please visit http://www.cpanel.net.

cPanel requires a license for each instance. This applance will not function without a license for the Primary IP address of the server. For licensing information, please visit http://cpanel.net/dist.cgi
