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.


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


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