Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I just recently set up a DNS server and I'm having problems with it trying to resolve internal ip addresses. As of right now everything seems to be working ok except for when I try to ping a box or telnet to a router by the name it can't find it unless I type the domain along with it. For instance:
typing hostname.domain.net works fine however,
typing hostname results in nothing.
I had it setup where it would do it once before but the box got hosed and now I have to start from scratch and don't remember how I had it set up from before.

I think that this a client issue: you may need to specify a default domain on the client in order to use hostnames without a domain. On Linux this may be manually set in /etc/resolv.conf, but the default search domain probably ought to be issued by DHCP if the system uses it.
Try using nslookup to see what happens. If nslookup for a registered system on your network without a domain name result in NXDOMAIN I would double-check that the both the DNS server and the clients have the correct search domain set. Since a lookup by FQDN succeeds, DNS itself is probably operating correctly.
Although this isn't likely to be the issue, you probably ought to use lowercase for names of hosts and domains. Although DNS will cope, the fact that UNIX systems are case-sensitive means that names like Boss.Saleen.net may cause problems later. For example, I've had mail systems break because of issues with case-sensitivity.
