When I began writing this book, the first question I asked myself was how to
install Linux on a server, and be sure that no one from the outside, or
inside, could access it without authorization. Then I wondered if any method
similar to the one on Windows® exists to improve the computers
performance. Subsequently, I began a search on the Internet and read several books
to get the most information on security and performance for my server. After many
years of research and studies I had finally found the answer to my questions.
These answers were found, all scattered throughout different documents, books,
articles, and Internet sites. I created documentation based on my research that
could help me through my daily activities.
Through the years, my documentation grew and started to look more like a book
and less like simple, scattered notes. I decide to publish it on the Internet so
that anyone could take advantage of it. By sharing this information, I felt that I
was doing my part for the community who answered so many of my computing needs with
one magical, reliable, strong, powerful, fast and free operating system named Linux.
I had received a lot of feedback and comments about my documentation, which helped to
improve it over time.
