Overview

Effective systems administration is the key minimising down-time and ensuring the smooth running of Unix and Linux systems. This course covers both the day-to-day administrative tasks and the less frequent tasks such as configuration.

This course is generic and the material can be applied to most Unix and Linux Systems. It has a high hands-on content so that participants can apply the theoretical concepts.

Objectives

On successful completion of this course, participants will be able to:

• Understand the super-user (root) privileges
• Partition hard disks and create file and swap systems
• Manage the file system
• Administer user accounts
• Customise the boot sequence
• Backup and restore file systems
• Schedule 'cron' tasks for later execution
• Administer print services
• Configure NFS and NIS

Audience

This course is for potential sytems and network administrators and for support personnel.

Prerequisites

Familiarity with Unix and/or Linux, including shell programming, up to the level covered in the Introduction to Unix/Linux and Shell Programming course is assumed.
