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.

Hello, I recently finished installing/configuring BIND on a Scientific Linux 6.0 bpx. I registered a domain name through godaddy.com and set my SL 6.0 box to be the primary master for DNS. Now, I only have access to one public/WAN IP, and it looks like I am unable to subnet the IP to make more IP addresses. (It's a virtual server on another Linux box). My question is, how secure is my DNS. I read several books/guides on the internet to setup DNS/BIND. I did manage to get the chroot jail going, but wasn't sure if there are any security risks that I need to be aware of. Are there commands similar to nslookup/dig that could help troubleshoot the security of my DNS server?
Bind doesn't exactly have the shiningest of shining reputations as far as security is concerned. So, a big part of this is whether you manage to keep bind promptly patched for ever and always. I guess most people stray quite far from that ideal...
Did you understand networking and set up the most restrictive of firewalls when you set it up? That would probably improve things.
What are the implications of a denial of service, for you? For some people, it would be an irritation for others it would cost them big time.
