    LS103 - Linux Advanced System Administration


    40 Hours


    Attendees of this course will learn how to perform the advanced Linux system administration functions. Topics include installing, upgrading, and removing software packages, installing and configuring a new kernel, managing modules, managing hardware, managing processes and tunable parameters through the /proc filesystem, managing swap space, setting up a network filesystem and auto mounting NFS resources, configuring the system logging daemon, establish and maintain system security, and troubleshoot and correct problems.

    Although the Red Hat Linux Operating System is used as the training platform, the information in this course can be easily adopted to other Linux systems.


    This course is designed for experienced system administrators who will be performing advanced system administration procedures on a Linux operating system.
