Anotace:

Students learn the internals of the UNIX operating system and the administration of its basic subsystems, and get practical skills on real-world examples. They understand the differences between the user and administrator roles. They understand theoretically and know practically system monitoring, analysis and tuning tools; file systems implementation and administration; disk subsystems; processes; memory; network services; shared file systems; naming services; remote access; system boot.

Požadavky:

User-level knowledge of the UNIX system (as provided by the Introduction to Operating Systems module) is required. Knowledge provided by the Operating Systems module is recommended.

Cíle studia:

The UNIX operating system has always strictly distinguished the user role from the administrator role. Responsibility for system operation is delegated to the administrator. A small mistake on the administrators part may have fatal consequences. In this module, students gain basic knowledge necessary for administering a UNIX-based OS that they can immediately apply in the real world, e.g., to administer their Linux notebooks or enterprise servers.
