A quick How To For today create ISO file from CD or DVD using command line.
Usually I use this command to get an ISO image from Disk for operating system, for example I have Kubuntu 10.04 LTS on a Disk, and i want to use that image on my virtual machine, instead of keeping the CD inside my CD ROM all the time.

10 free GNU/Linux Administration Books
Linux based distributions have a lot of different administration options and privilege options, Books listed here will help you with administrations privilege for different distributions debian, fedora, redhat, ubuntu, gentoo, opensuse, mandriva, …..
Also other books for security administrations, and files system directory hierarchy, software help you to secure you system, securing VPN servers,…
## so here we go…
This documentation will attempt to summarize the installation and configuration, as well as the day-to-day administrative and maintenance procedures that should be followed to keep a Linux-based server or desktop system up and running. It is geared to an audience of both corporate as well as home users. It is not intended to be a full overview of Unix operations, as there are several good texts available as well as on-line documentation which can be referred to in cases where more detailed information is required.
The Linux System Administrator’s Guide, describes the system administration aspects of using Linux. It is intended for people who know next to nothing about system administration (those saying “what is it?”), but who have already mastered at least the basics of normal usage. This manual doesn’t tell you how to install Linux; that is described in the Installation and Getting Started document. See below for more information about Linux manuals.
The filesystem standard has been designed to be used by Unix distribution developers, package developers, and system implementors. However, it is primarily intended to be a reference and is not a tutorial on how to manage a Unix filesystem or directory hierarchy.
There are numerous definitions for “computer security”, and most of them are correct. Essentially computer security means enforcement of usage policies, this must be done since people and software have flaws that can result in accidents, but also because someone may want to steal your information, use your resources inappropriately or simply deny you the use of your resources.
This manual assumes the reader is familiar with using a Unix system and/or understands Debian User Reference Manual. Additional reading for System Administrator is Debian GNU/Linux Network Administrator’s Manual. Both of these are available from the Debian Documentation Project. Another useful book is “Linux System Administrator’s Guide” by Lars Wirzenius, available from Linux Documentation Project, http://metalab.unc.edu/LDP/ .
The target audience of the book is anyone who wants to deepen their understanding of how computer systems work, as well as anyone who is likely to become involved with the technical aspects of computer intrusion or system analysis. These are not only system administrators, incident responders, other computer security professionals, or forensic analysts, but also anyone who is concerned about the impact of computer forensics on privacy.
Call it the Linux fallacy. It’s the conventional wisdom that says Linux/UNIX gives you lots of power and reliability in exchange for far more complex and costly systems management. But in fact Linux/UNIX shouldn’t be a tradeoff–as long as you also implement a set of proven best practices.
The GNU/Linux systems have reached an important level of maturity, allowing to integrate them in almost any kind of work environment, from a desktop PC to the sever facilities of a big company.
In the course Systems Administration. It is an attempt to give you an overview of the course and more importantly of computing, Linux and Systems Administration.
Many students commented that they felt lost in the detail of Linux without having an overall picture of how it fits together. Hopefully this chapter will go some way towards solving this problem, and will provide some sort of small map and compass so you have an idea of where you are and where you are going.
The aim of this book is to get you up to speed with GNU/Linux and to deliver a fun and productive environment. It guides you through the many different regions of a GNU/Linux system with a focus on getting your desktop environment to do what you want it to do. It is comprehensive with basic support for the user who installs and maintains the system themselves (whether in the home, office, club, or school). It provides insights and step-by-step procedures that deal with specific tasks in setting your system up and maintaining it. The book covers many of the core features of a GNU/Linux system and you will gain the knowledge to enjoy and use one of the most comprehensive and useful developments in the history of computing.
