Overview

To attend this course you must have a good command line knowledge of Linux or Unix. We start from the installation of Linux systems and dive straight into the configuration of the system, so if you don’t know how to use Unix commands, or the manual pages you will be lost. The approach of the course is to try to give an excellent understanding of the Linux systems and their configurations from a generic perspective using SuSE and RedHat, in a large organisation, but will also suit smaller businesses. The course works you through from installing, through file systems and users and onto centralised network administration and more efficient administration.

Prerequisites

A Unix/Linux Fundamentals course and 3 – 6 months solid hands on use of Unix/Linux. Alternatively if you have 2 or more years of Unix/Linux hands on or are converting from Unix to Linux this is acceptable.

Delegates will learn how to

• Plan and install Linux systems confidentally
• Install software as required
• Configure and choose suitable file systems
• Work with dynamic file systems
• Create users, groups and default configurations
• Debug system problems and fix them
• Understand the start up sequence and configure it
• Set up security for the system and across the network
• Set up and configure NIS, DNS and routing
• Use networked file systems for Unix and Windows

DNS

Setting up a DNS server and maintaining it, and client systems.

Useful Services

Setting up and maintaining Apache and Sendmail, from a basic approach. This is not a definitive section, just enough to get you going and find out more.

Monitoring, Performance & Tuning

Looking after the health of your Linux systems. This section will show you the tools available and what to watch out for.
