Overview

Effective systems administration is the key to minimising down-time and ensuring the smooth running of Unix 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 systems. It has a high hands-on content so that participants can apply the theoretical concepts.
