The LPI certification is a great way to show you have Linux system administration knowledge. Especially when you don't haven working experience a certification is a valid tool to show you do have special knowledge about the operating system. The problem is the LPI didn't create the certification for people without experience. As a matter of fact, the exam is actually aimed at finding experienced administrators. That's why they have a lot of questions about stuff you don't encounter all the time, like little used options for command line arguments.

The /proc/sys directory in the /proc virtual filesytem contains a lot of useful and interesting files and directories. Many kernel settings can be manipulated by writing to files in the proc filesystem. A lot of important information can be retrieved from these files. This is especially useful when you are troubleshooting or fine tuning your linux system.
Following is a description of the most important files.

Especially the files in /proc/sys/vm are very interesting and useful.

This is the 3rd part of a series of articles aimed at teaching the knowledge needed for passing the LPI level 1 exam 1

I've put up a certification practice quiz containing questions similar to those on the certification exam. Take a challenge to test your knowledge level, just for fun or to practice your skills.

I've also put up some questions about the proc directories for people who need to learn these for the exam. I'll add more questions to all practice quizzes in the future.

Practice exam questions on this site!

I've put up a quiz on the site which has 25 random chosen questions to test your level of knowledge. They are chosen random from a pool of questions. The difficulty level and material covered is that of the LPIC 101 exam. If there's demand I'll put up more questions and other exam levels.

Register for free and try your skill level:

The LPI certification is a valuable certification for Linux system administrators. LPI has partnered with Novell and now the certification has become even more valuable as it's also a Novell certification by now which means you get 2 certifications at once. The LPIC 1 certification is also the base for the ubuntu certified professional certification. So if you like to become a linux all-round certified administrator. This is probably one of the best (and cheapest) choices.

This is the first article in a series of tutorials, which will try to help you prepare for the LPI certification exam.

I've been working on my project for learning perl Gui programming. What I want to do is create a Gui interface for Linux commands. Not because I think there's any need for such a thing but just because I think it provides a good base for learning Perl. It's not meant to be production software but maybe I can turn it in to a learning tool for linux commands or something.

If you are looking for a hosting provider for your new website, or want to upgrade your hosting services your going to get confronted with a lot of options. It may not be completely clear what the differences are.
No doubt you probably want some kind of Linux hosting as there are only very specific circumstances where windows web hosting has benefits. In my humble opinion you would only want windows hosting if you have a web service or application which can only be run on windows(which would be a design flaw).

Reasons why Linux is superior for web hosting include:

As I'm trying to learn perl, and I'm trying to learn perl GUI programming in the process I've been browsing the internet for information. I've chosen perl-Gtk as the GUI framework for the start of this journey, there are some arguments against this choice as readers commented in previous articles, but I'm happy with it.

In my previous article I described installing the EPIC plugin in Eclipse. I think this is a great editor and I definitely appreciate it a lot. I do have some problems with it, it seems to me it's a bit buggy, if you just want to use it for writing code you won't have this problem, but I want to use it for debugging and there it gives me some problems (crashing, unexpected results). It works OK for some programs but I want to use it for debugging GUI programs and I'm afraid it just isn't perfect for the job(yet).

I need to extend my programming knowledge, I know as a system administrator, I should automate everything I need to do more than twice and therefore I need more programming skills. I've been thinking of learning shell programming, as it is the most ubiquitous in Linux systems. I already know some shell programming and for most of the simple tasks I can easily write a small shell script. The problem is I really need more to become more skilled, to speed up the things I do and make my life easier.

If you like me upgraded to ubuntu 9.04 jaunty jackalope changes are that you are confronted with a login screen at startup. Here's an easy way to get back your settings to login immediately.
