There's so much to say, this book is perfect and Amazon.com completes the equation. First of all this book has it all, it really reaches out for all audiences with different levels of experience. It goes around explaining stuff related to Linux directly and talking about general information related to the corresponding field. I mean I am still an undergraduate student who is a MCSE, but hasnt practiced networking in a long time, and this book was an amazing revision for DNS servers, host files, cables, configuration topologies and everything!! It even taught me how to extend my knowledge's potential with Linux's powerful networking capabilities which was my main reason to start with the transition. Second of all Amazon.com is really an excellent company and I am very very happy and satisfied with it, I have never seen such professionalism and dedication towards the satisfaction of customers, even overseas ones!! My order was thought to be lost, and I was issued as quickly as a lightning a replacement order to find out that my original order wasn't lost, but stumbled over customs in my country, then I was thanked by Amazon.com because I told them I recieved my original order, and that the costs of returning it back was on them and it is totally refunded!!

I am really perfectly satisfied with everything, the book and the company, and I can't wait to order again!!!
