This book presents the core fundamentals of Linux in a manner that is very logical and easy to follow.” —Greg Kurtzer, CTO, Infiscale, Inc. “ Wale continues to do a great job explaining complex information in a straightfor- ward manner. All newcomers should start their Linux library with this book.” —Ron Hudson, Senior Field Support Engineer, Intervoice, Inc. “ Wale Soyinka did a stellar job in the fourth edition and he was up for the chal- lenge of making the fifth edition his own. It is with great pleasure I present the fifth edition of Linux Administration: A Beginners Guide by Wale Soyinka. This book barely resembles the 500-odd pages written nine years ago in the first edition, and it is without hesitation that I say his new words are for the better.” —From the Foreword by Steve Shah, original author of Linux Administration: A Beginner’s Guide ABOUT THE AUTHOR Wale Soyinka (Canada) is a systems/network engineering consultant with several years experience in the field.
