Linux TCP/IP networking for embedded systems / Thomas F. Herbert. Charles River Media, 2007

Find out how the TCP/IP stack is implemented in Linux. This book is for the kernel hacker, not the applications programmer. Not an easy read, but much easier than learning from reading the networking code.  The title is misleading, because you don’t need to be working on embedded systems to make good use of the book.

Silence on the wire : a field guide to passive reconnaissance and indirect attacks by Michal Zalewski. No Starch Press, 2005

This book on internet security is much different than most. Firstly, it is a joy to read! It has no dry descriptions of the latest vulnerabilities, but instead it delves into the technologies that underlie the Internet, and explores their inherent limitations.
