Open Source Network Administration

A host of open source tools are available to help you accomplish network management chores. This sample chapter from Open Source Network Administration looks at one of them—the Multi Router Traffic Grapher (MRTG)—which enables you to view graphs of current bandwidth usage as well as usage over time. Having a historical perspective can be invaluable in diagnosing operational problems or potential attacks that might be difficult to pick up by viewing only immediate network traffic patterns. This chapter looks at what MRTG can do and explains how to install, configure, and maintain it.
