Chapter 9


First of all, thanks to all these people who have been working very hard to bring us this open source technology and a special thanks to Linus Torvarlds because without his release of the kernel nothing would be as it is today.

In this section you will realize the important advancements we have made towards open source software. Believe it or not 80% of web servers on the Internet are running the very famous apache web server, sitting most likely on a version of GNU-Linux. Companies have saved thousands or millions of dollars implementing open source software because companies don't have to purchase licenses whenever they need to implement a new server or more workstations.

When I started learning Linux, I realized what good is it to have such a wonderful operating system with all these free servers on it if there is no step-by-step documentation for it. Yeah, yeah… you can find 500 plus page books etc., but how many users and technicians understand them? I mean it is nice to know that these servers exits -but I wanted to set one up. I didn't want to give up, and I started browsing the Internet in search of how to do this, how to do that…

Anyway, I was lucky to get DSL through DirecTV with a static IP at a very low price; which made it possible to go live with all my servers. It is unfortunate that DirecTV no longer provides Internet services.

Welcome to the server section, I am sure that you bought this book because you really want to learn something, right? As I promised you from the beginning of this book, you will learn. I put together this information to teach you something; and I'll be very glad to hear that I really have accomplished your Linux education.

I wanted you to know that schools don't teach this kind of stuff, no matter how much they promise it. Many schools have the right developed program for such purpose, but even though, they hire teachers that are not qualified for the subject. Keep in mind that it is 1000 times better to find a good experienced friend that can teach you what you need to learn than spend $5000.00 for a training class. I swear, and I bet you that no training can teach you what you really want. No matter if you hear the schools' name over a million times on TV, remember it is just an advertisement. That is all.

When you go out and buy a Desktop computer, what difference does it make which name brand it is? When you really know about computers you can build one yourself. If you know how to build one you could double the quality or performance with the same price you spent on a brand name machine and get the extra devices that you really want. I understand that some of you like the name.
