Richard Bejtlich, Tao Security: Prospective TDS readers should understand that this book is unlike any I have read on operating systems. Readers will not have to skip pages on setting up Apache or configuring BIND, thankfully! Instead, TDS covers core system administration subjects to a degree I have not seen elsewhere. [...] Krafft takes readers on an inside tour of the how and why of Debian. Rather than just explaining a technique or tool, the author discusses the overall problem, possible ways to approach it, and Debian's solutions. He presents pros and cons for each, and then demonstrates usage with command line syntax and sample output.
