Snort (“The Open Source Network Intrusion Detection System”) really isn’t very hard to use, but there are a lot of command line options to play with, and it’s not always obvious which ones go together well. This documentation aims to make Snort easier to install and to use for new users. We will install Snort in the “Network Intrusion Detection” mode. This mode is the most complex mode but is allowing Snort to analyse network traffic for matches against a user defined rule set and perform several actions based upon what it sees. This guide contains all the necessary information for installing and understanding the architectural layout of the implementation. It was written with the assumption that you understand how to run Snort and have a basic understanding of Linux Mandrake. This includes installing Linux Mandrake and RPM packages, editing files, making directories, compiling software and understanding general Unix commands.
