About the author

Agustin Velasco has over 15 years of experience in electronics and computer systems. Throughout the years he has earned a career in the technology arena, specializing in computer security and Data recovery.

By the end of 1995, he had an opportunity, and worked for a subdivision of Acer America, where he spent four years developing his skills in computer technology. Thereafter he was self employed, deploying networks and applying security at large scale. As a security specialist, he saw the need and mastered a technique in data manipulation which now he can use to recover lost or erased data from a variety of platforms.

As Linux became popular on the market, he started to experiment with it, and found that Linux is a highly reliable operating system. He started working with various Linux distributions including Slackware and Debian. Realizing that the end user might have problems working with some distributions, he started working with other more friendly packages. Soon after, he developed a technique based upon the Mandrake distribution.

He is currently an active supporter of the open source movement. Due to the lack of technical reference for the end users, he decided to write Agustin's Linux Manual “the series”. Because of this documentation he receives the respect of the Linux community. On a day to day basis, Agustin's Linux Manual is used among top IT professionals and is now reaching educational institutions. Agustin currently participates in various forums, including chat rooms, where he answers questions related to the Linux Operating system.

Agustin is currently holding a position as technical director at www.netcontrol.org and is author of the second edition of these series based on Mandrake 10 Community Edition.

The purpose of this book and why it was written

This book has been written to help all of those who are interested in learning, are open minded and loves freedom. The book is written especially to assist educational institutions to teach people who have zero knowledge of Linux and perhaps for those who can not afford the pricy schooling but want to become a well respected system administrator.

The book takes one step by step from installation to system administration. It teaches how to set up Apache web server, Bind DNS server, Postfix email servers, Samba server and of course security. It gives you details on how to close unnecessary ports. It covers configuration on the Squid proxy server and demonstrates many of the available utilities that will assist you in system administration

Dedication

For my wife Amelia and my two kids Caroline and Kevin. I am really happy for having such a wonderful family, my wife for understanding and supporting me with all of my crazy ideas and my kids for not bothering me when I am writing or working on projects at home.

And last but not least to all of those who struggle in life to have an education, but never give up to demonstrate their abilities of accomplishing something. I myself have witnessed people without a degree who have accomplished the most wonderful skills but because a lack of a degree they have been put out of the practical field.

Acknowledgement

I'd like to thank my friend Anthony Whitaker (who lives in the shadows and wishes to remain anonymous); an idea man who undoubtedly could make any company number one and has been so helpful in the process of this book. Without his support this book wouldn't be completed. Anthony has a wide experience in the field of computers which made him a perfect person to review this book as an end user.
