This book takes a Chilton's manualdiagnostic approach to solving these problems.The book begins by presenting the two most common Linux firewallconfigurations and demonstrates how to implement these configurations in animperfect network environment, not in an ideal one. Then, the authors proceedto present a methodology for analyzing each problem at various network levels:cabling, hardware components, protocols, services, and applications.
