“Since I’m in an educational environment, I found the content of Sobell’s book to be right on target and very helpful for anyone managing Linux in the enterprise. His style of writing is very clear. He builds up to the chapter exercises, which I find to be relevant to real-world scenarios a user or admin would encounter. An IT/IS student would find this book a valuable complement to their education. The vast amount of information is extremely well balanced and Sobell manages to present the content without complicated asides and meandering prose. This is a `must have’ for anyone managing Linux systems in a networked environment or anyone running a Linux server. I would also highly recommend it to an experienced computer user who is moving to the Linux platform.”
—Mary Norbury, IT Director, Barbara Davis Center/University of Colorado at Denver, from a review posted on slashdot.org
“I had the chance to use your UNIX books when I when was in college years ago at Cal Poly San Luis Obispo, CA. I have to say that your books are among the best! They’re quality books that teach the theoretical aspects and applications of the operating system.”
—Benton Chan, IS Engineer“The book has more than lived up to my expectations from the many reviews I read, even though it targets FC2. I have found something very rare with your book: It doesn’t read like the standard a technical text, it reads more like a story. It’s a pleasure to read and hard to put down. Did I say that?! :-)”
—David Hopkins, Business Process Architect“Thanks for your work and for the book you wrote. There are really few books that can help people to become more efficient administrators of different workstations. We hope (in Russia) that you will continue bringing us a new level of understanding of Linux/UNIX systems.”
—Anton Petukhov“Mark Sobell has written a book as approachable as it is authoritative.”
—Jeffrey Bianchine, Advocate, Author, Journalist“Excellent reference book, well suited for the sysadmin of a Linux cluster, or the owner of a PC contemplating installing a recent stable Linux. Don’t be put off by the daunting heft of the book. Sobell has striven to be as inclusive as possible, in trying to anticipate your system administration needs.”
—Wes Boudville, Inventor“A Practical Guide to Red Hat® Linux® is a brilliant book. Thank you Mark Sobell.”
—C. Pozrikidis, University of California at San Diego“This book presents the best overview of the Linux operating system that I have found. . . . It should be very helpful and understandable no matter what the reader’s background is: traditional UNIX user, new Linux devotee, or even Windows user. Each topic is presented in a clear, complete fashion and very few assumptions are made about what the reader knows. . . . The book is extremely useful as a reference, as it contains a 70-page glossary of terms and is very well indexed. It is organized in such a way that the reader can focus on simple tasks without having to wade through more advanced topics until they are ready.”
—Cam Marshall, Marshall Information Service LLC, Member of Front Range UNIX Users Group FRUUG, Boulder, Colorado“Conclusively, this is THE book to get if you are a new Linux user and you just got into RH/Fedora world. There’s no other book that discusses so many different topics and in such depth.”
—Eugenia Loli-Queru, Editor in Chief, OSNews.comThe Best Just Became BETTER—Again! Completely Revised to Meet All Your Fedora Core and Red Hat Enterprise Linux Needs! Fedora Core and Red Hat Enterprise Linux are advanced operating systems. You need a book that’s just as advanced. This book explains Linux clearly and effectively—with a focus on features you care about, from system security and Internet server setup to Windows file/printer sharing. Best-selling author Mark Sobell starts at the beginning and walks you through everything that matters, from installing Linux using the included DVD to working with GNOME, KDE, Samba, sendmail, Apache, DNS, NIS, and iptables.
This edition contains extensive coverage, including full chapters on using Linux from the command line and GUI; even more thorough system administration and security guidance; and up-to-the-minute, step-by-step instructions for setting up networks and every major type of Internet server. Along the way, you learn the “hows” and the “whys.” Mark Sobell knows every Linux nook and cranny, has taught hundreds of thousands of readers, and never forgets what it’s like to be new to Linux. Whether you are a user, an administrator, or a programmer, this book gives you all you need—and more.
