One of my major projects over the last year was to move our entire email system away from Microsoft Exchange 5.5 over to an open-source platform. I chose FreeBSD for various reasons, but had no printed manual; something I find somewhat essential whilst working on big jobs. I bought this book and can now look back and thoroughly recommend it to anyone who is thinking of stepping into this field of computing. It was great for me as I had very little experience of setting up a UNIX box but am competant on a variety of Windows platforms. It's taken me from being a complete UNIX novice and guided me through setting up the replacement server, installing the required software and just about everything else. I've had it a year and still find myself dipping into it for reference and it still contains stuff that I will be doing in the future.
