Linux is based on UNIX and networking started there. Networking will
work for you!
I normally install both GNOME and KDE, but 99% of the time, I use GNOME. When I
install from a DVD, I install the majority of Applications and Systems
things I want at
that time. Then, in a Terminal Window (as root), do "yum update" to
update everything
to the latest version, for Security and Stability reasons.
In GNOME, at the lower left hand corner, click on System >
Administration >Network and enter the password for root (the super
user).
That brings you to a GUI utility called system-config-network Be sure
that eth0 is shown as "Active" and then highlight it and click on
"Edit". Be sure that "Activate Device when computer starts is
checked". And, "Automatically obtain IP with DHCP". And, Automatically
obtain DNS.
A book I can recommend to you, would be the edition that covers Red
Hat Enterprise Linux 5, of "Red Hat Fedora and Enterprise Linux
Bible" by Christopher Negus. I'm sure that there are other excellent
books, but this one will explain a lot to you. I think the version
that covers RHEL 5 (CentOS is a rebuild of RHEL) is "Fedora 6 and Red
Hat Enterprise Linux Bible", however you need to verify that, before
you buy it, because I have an older version of the book. Please note
that much of the book is about Fedora Core. Red Hat Enterprise Linux
takes the best of Fedora Core and is a much more stable distribution,
without the "latest and greatest". So, the book will help you with
CentOS, because CentOS is a rebuild of RHEL.
