This page describes the topics that are important for systems administrators to know as well as links to where information can be found about these topics. There are two main sections:

Background Topics

Background information, stuff you wouldn't normally have a class to teach, but is important for students to have access to definitions and an understanding of the concepts. For instance you would need to understand IP-Addresses in order to be able to teach a network management under Ubuntu class, but you wouldn't want to spend a lot of time teaching it.
