If you've come to Linux Ubuntu from Windows, you probably left behind a few favorite computer games. You may already know that Wine can help you play them again; in some cases, however, the solution is less than perfect.That's where this tutorial can help.

Joomla is an award-winning open source CMS that lets you create “business” or professional-looking websites directly from scratch. Contrast this with WordPress, which by default is a blogging platform and gives websites the appearance of a blog after installation. By the end of this tutorial, you will know how to install a fully running Joomla website directly from scratch using the Linux Ubuntu/XAMPP web server.

This is an important tutorial on how to install and completely configure XAMPP to run without problems on Ubuntu Linux.

In the first part of this two-part series, you learned the network communication concepts you need to know to understand the operation and data provided by Wireshark. I also covered the installation steps and some very basic configuration. This part will delve more deeply into using Wireshark for analyzing your network.

Do you need to sniff out and spy on network communications in a LAN, WAN or any network configuration? Or have you found yourself in a difficult situation troubleshooting network-related problems inside and outside of your network? Then you need a network analyzer to examine the packets going into and out of certain media. Wireshark can help. Keep reading to find out how.

When two people are able to communicate we generally assume that they know the same language, and that is the key to understanding each other. This applies to the world of computing as well, where the set of standards are called protocols. During this article we plan to present in a nutshell the most common TCP/IP protocol types. We won’t get in-depth, so don’t expect university course-style material—just the basics.

The majority of computer users are familiar with BIOS options as long as they don't go further than selecting the main bootable device or ordering that priority list such as HDDs first, then optical drives, and so forth. In the past few years, however, another option has appeared there. It’s called Network Boot or the infamous PXE Boot. In this article we will give a brief overview of the basics of network booting.

Installing, configuring, and administering an e-mail and groupware server can be quite a tough job. Scalix is a remarkable open source server of this kind; it is based on HP OpenMail. Scalix can be used by beginners, but in terms of administration, it requires solid know-how. This book targets Linux administrators that intend to work with Scalix e-mail servers.

We have all heard that the vast majority of computer users still associate working with UNIX-like operating systems with some kind of black art. Others know the basics, but are afraid to endeavor into areas that look tremendously advanced. Today we are going to review the book Network Administration with FreeBSD 7. It’s all about building, securing, and maintaining networks with the FreeBSD operating system.

In this conclusion to a two-part article on the anatomy of an information architecture, we take a close look at its typical components.

In this conclusion to a two-part series on load-balanced clusters, you'll learn how to configure the load balancer and test the system. This article is excerpted from chapter seven of Linux System Administration, written by Tom Adelstein and Bill Lubanovic (O'Reilly, 2007; ISBN: 0596009526). Copyright © 2007 O'Reilly Media, Inc.

If you want or need the power of a supercomputer but can't afford one, you might look into creating a computer cluster. If you're interested in this relatively inexpensive solution, this two-part article series gives you a good introduction.

UNIX format timestamps have an extensive range of use. You will find out the main reasons that back up this claim, but for now, let’s say that it is because working with dates and times in the UNIX time format is easier and more resource efficient. In this article, our goal is to demystify the concept, learn the theory that lies behind it, and ultimately write algorithms and implementations that convert dates back and forth from the traditional ISO standard to UNIX format.

In this conclusion to a three-part series on the Concurrent Versions System (CVS), you'll learn how to commit changes and add and remove files. This article is excerpted from chapter two of Essential CVS, Second Edition, written by Jennifer Vesperman (O'Reilly; ISBN: 0596527039). Copyright © 2007 O'Reilly Media, Inc. All rights reserved.
