Everything you need to know about Nmap,
This review is from: Nmap Network Scanning: The Official Nmap Project Guide to Network Discovery and Security Scanning (Paperback)
Having the privilege of reviewing draft copies of this book over the past couple years, I think it will quickly become required reading for network engineers, system administrators, and anyone working in the computer security arena.
Fyodor, the developer of nmap, is the obvious choice to author a book on his project. This book, however, goes well beyond an expanded "man page" for the premier port scanning tool. Fyodor gives an insightful overview of TCP/IP (including some really beautiful graphs of IP headers). He also shows how to use nmap for network monitoring, to gain a better understanding of networks, and to test firewalls.
Consider this book a Rorschach test of sorts. If you want to learn how to inventory your network gear, this book has an answer. If you want to learn how to bypass firewalls and IDS, this book will help. If you need to test network security, this book will be required reading.
I have been using nmap for nearly a decade and there were still some great tips and tricks that I found for the first time in these pages.
Thanks for the effort Fyodor.
