IPv6 in Practice: A Unixer's Guide to the Next Generation Internet /by Benedikt Stockebrand (Author).Handling IPv6 for the first time is a challenging task even for the experienced system administrator. New concepts and mechanisms make it necessary to rethink well-established methods of the IPv4 protocol. This book is a practical guide to IPv6 addressing Unix and network administrators with experience in TCP/IP(v4) but not necessarily any IPv6 knowledge. It focuses on reliable and efficient operation of IPv6 implementations available today rather than on protocol specifications. Consequently, it covers the essential concepts - using instructive and thoroughly tested examples - on how to configure, to administrate, and to debug IPv6 setups. These foundations are complemented by discussions of best practices and strategic considerations aimed at overall efficiency, reliability, maintainability, and interoperation.
The examples in this book cover all relevant aspects concerning Debian GNU/Linux, FreeBSD, and Solaris.

Beginning the Linux Command Line/by Sander van Vugt (Author) .This is Linux for those of us who don’t mind typing. All Linux users and administrators tend to like the flexibility and speed of Linux administration from the command line in byte–sized chunks, instead of fairly standard GUIs. Beginning the Linux Command Line follows a task–oriented approach and is distribution agnostic.
