Administering Linux Systems

Administering Linux Systems Course Overview

Our four day Linux course provides a thorough understanding of key Linux administration activities, encompassing both the system hardware and kernel, as well as a number of front end tools. The course will cover steps for every major distribution of Linux including SUSE, Debian and Ubuntu, including similarities and differences between the platforms. 

Our Administering Linux Systems training course will provide delegates with the ability to conduct necessary administration, security, and performance exercises on a Linux system. Delegates will become familiar with setting up Linux, updating Linux, controlling account data, software package management, and carrying out backups. As well as this, delegates will explore device data, connecting to the network, and producing solutions to boot problems.

By the end of this training course, delegates will possess a technical understanding of what it takes to manage Linux. During the course, they will investigate the configuration of security, administration, and network concepts in a hands-on manner, which will further embed their acquired knowledge.
