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 was reading a post in the 'installation' lists and it mentioned that they should recompile their kernel for more speed.. what did this mean?? not the recompile but what could you add to the kernel that will tweak it that much..
the kernel contains a lot of junk basically. When you release a shrink wrapped box with a system inside it, that system needs to work on as many machines as possible in order for it to be useful. consequently there are lots of things compiled into the kernel that are not needed, and when the kernel is bigger, it naturally uses more memory and is slower and can affect the performance of your system. For instance i have no scsi devices, so i ave no scsi drivers in my kernel. and lots of other things like that.
my own kernel isn't tiny, BUT:
-rw-r--r-- 1 root root 1058833 Nov 9 00:35 vmlinuz-2.4.13-6mdk
-rw-r--r-- 1 root root 778629 Dec 27 13:13 vmlinuz-2.4.17
the main thing for recompiling a kernel is to add processor optimizations and get rid of junk - it's not really what you can add, it's what you can take out of the kernel that speeds it up. a smaller kernel is faster and more stable than a large kernel.
You will probably already have a compiler installed, or if not your distro will have a way of installing it through whatever package system they use. Look for "gcc". While you're getting that, you might want to install the kernel source as well. The source for the version you are using will be available in your distro somehow, or if you feel like upgrading, go check out http://www.kernel.org.
I read some of the post and run Kernel Configurator in Mandrake Linux 8.1. It gave me a text file. What are the steps to compile a kernel. I read the Kernel How to's and I still don't understand it. Can someone summarize the steps or the command lines that I need to type.
