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 currently have vector linux installed and I'm trying to install centos 6.3 on my laptop from my hard drive because my cd/dvd rom can't read dvds but reads cds. I'm using the CentOS-6.3-i386-netinstall.iso to start the installation. I have both CentOS-6.3-i386-bin-DVD1.iso and CentOS-6.3-i386-bin-DVD2.iso on /dev/sda2 and checked their md5sum and they match. After I choose the packages I want to install and click next to start the installation, I get the following error:
A fatal error occurred when installing the ca-certifcate package. This could indicate errors when reading the installation media. Installation cannot continue.
Installing ca-certificates-2010.63-3.el6_1.5.noarch (1 MB)
The Mozilla CA root certificate bundle
I tried several times adding/removing packages but I still get the same message.
When I tried to check the md5sum of the CentOS-6.3-i386-netinstall.iso cd using the following command:
maybe try downloading and burning a Centos cd? I think an iso has to be "unpacked" before it can be used directly, if you are using it on an active system that might cause problems in its self.
