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.

"Scientific Linux 6.2 is now available for download. Differences from 6.1: Anaconda - added the Scientific Linux install classes, DVD installs do not ask for the network unless needed; OpenAFS updated to version 1.6.0, this packages includes a patch to disable NAT pings to avoid a race condition; livecd-tools and liveusb-creator updated from upstream to version 13.4; sl-release - removed Troy Dawson's GPG key, added CERN's GPG, added EULA; yum-autoupdate has had PRERUN and POSTRUN scripts added for more flexibility; the yum-conf-* packages now require yum-fastestmirror by popular request; the new x86_64 Adobe repository is now available....

Free version of Red Hat: very stable and reliable
but CentOS is better
If I rate this at 7/10, why donít I recommend it? Scientific Linux is an in-house project from CERN and Fermilab: what you get is what they want. CentOS is a community project, and the most widely-used distro for web-servers: what you get is what a lot of users want. The SL web-site has little useful information, while the CentOS one has a great deal, plus links to Red Hatís documentation. If you intend to enable any third-party repositories, for example, you must read the advice about setting priorities on the CentOS site.
SL comes in 5 formats.
Firstly, the 2 DVD set, like CentOS or Red Hat itself, with the entire repository and customisation available, including a choice of Gnome, KDE, or Icewm.
Secondly, a single DVD: slightly reduced (3.5GB rather than 5GB), but with the same customisation options.
Thirdly, a live DVD (2GB). If you install from this, Gnome, KDE, and Icewm will all be installed, with a lot of duplication and very confusing menus.
Fourthly, a live CD with Gnome desktop and very little software, even for a CD: Firefox, Thunderbird, Pidgin, Cheese, and Totem.
Fifthly, a CD with Icewm and no software, suggested as a rescue disk.
Icewm was included so that older computers at CERN could continue to be used. The problem is that if a computer is too small for Gnome or KDE, it's too small to run the Anaconda installer! The DVD installer lacks a text-based option and the live CD lacks Icewm. The live DVD has a text-based installer, but that will install KDE and Gnome as well as Icewm. The best option would seem to be to use the Mini CD and add your own software. A better option for a stable, long-term-support distro on a small computer would be Salix with Fluxbox.
Note that SL is not so-named because it is intended for scientists. It has no extra scientific programs, and actually lacks some that are in CentOS: e.g. gromacs, Macaulay, and qucs.
