As a newbie to Linux myself, I have found a couple of books that has been most helpful to me:
1) O'Reilly Publisher
"Learning Red Hat Linux"
Author: Bill McCarty
2) *Red Hat Linux 7.2
(Week End Crash Course)
Authors: Naba Barkakati & Kurt Wall
*Found this book accidently through Amazon.com
I believe the publisher may be Hungry Minds, Inc. They have been purchased by another company, I think,
but try www.hungryminds.com.
Both books I found to be helpful, especially the Red Hat Linux 7.2, in setting up my home network. I also spend a lot of time on Red Hat's web site. I also joined the Red Hat Network. Check out the web site, as well.
