7.1 An Overview of Cockpit

Cockpit is a light-weight, web-based interface that allows general system administrative tasks to be performed remotely. When installed and configured, the system administrator simply opens a local browser window and navigates to the Cockpit port on the remote server. After loading the Cockpit interface into the browser and logging in, a wide range of tasks can be performed visually using administration and monitoring tools.

Behind the scenes, Cockpit uses the same tools to perform tasks as would normally be used when working at the command-line, and updates automatically to reflect changes occurring elsewhere on the system. This allows Cockpit to be used in conjunction with other administration tools and techniques without the risk of one approach overriding another. Cockpit can also be configured to access more than one server, allowing multiple servers to be administered and monitored simultaneously through a single browser session.
