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 have an old pIII 600mhz 128mb pc. I installed RedHat 7.1 with minimum packages without xserver. (I checked only the gcc and vim while installing with total install size under 280 MB ). But still it takes around 3-4 mins to get the login prompt. It seems to be starting several unnecessary services. How can I disable these unwanted services (esp the hardward detection module) and make my pc boot up in less than a minute? (I am trying to learn shell scripting and basic unix OS functionality)
I have windows 95 freshly installed on the same machine which boots up under 45 secs. It seems strange that a command line OS like unix takes 5 times more time to boot than a GUI OS like windows.
That will only shorten the time you have to make a choice in grub or lilo. Better reconfigure the kernel, and remove any modules you don't have. When you use ``make xconfig'', you will have a very decent overview on what you're installing.
(That does not mean, though, that it will not take you ages to configure the slickest kernel you can )
I have sometime withou playin with RH n Fedora but...
Try "ntsysv" command as root.. disable all the shit u don't want
Also, (like was said before) recompile ur kernel. most distro try to enable things much more than u need.
Thanks for your replys. I am a begginer and compiling or reconfiguring the kernel seems to be a complex stuff. Please elaborate on reconfiguring the kenrel. I don't have xserver installed so I guess 'make xconfig' won't do any good. ntsysv seems to be a feasible solution...will try that out.
Hmmm. Maybe try a newer distro? RedHat 7.1 is pretty old. Maybe it's struggling with a particular piece of hardware. I have an old Celeron 400MHz system that boots in about 30 seconds on a stock Debian Sarge 2.6.8 kernel. And I even run KDE gui...
Kids these days are spoiled. If a boot up time takes longer than 5 minutes, you should worry. Making the boot time less can make it worst. Getting initng scripts to work with your Linux distribution is pain.
For Redhat like distributions, use chkconfig to enable or disable services for each runlevel that you do not use. By typing "service [service name] stop" as root or su - it will stop the service at that time. Redhat includes services that should not run at all like portmap and inetd or xinetd. Hotplug and updating the module list can take a long time.
Any distribution that I tried take the same amount of time at boot up. I do not care how long it takes if it is under 5 minutes and it does not crash. Gentoo is not fast as people say. It just runs fewer services. Gentoo developers have included parallel init service loading but an option have to be included in /etc/make.conf (I think) to do this. All my systems are fast in hardware but software is unable to speed it up.
