Yet Another Reason to Learn Linux – Linux Certifications
By Levi Reiss
There are currently four programs that enable people to become certified as Linux Systems Administrators. These programs are offered by the Computing Technology Industry Association, the Linux Professional Institute, the Novell Corporation, and Red Hat, Inc. The first two are professional industry associations whose certification programs do not depend on any specific Linux distribution. Novell and Red Hat Linux certifications are closely associated with their popular Linux distributions. Should you wish to prepare for either of these two certifications you will definitely need access to their Linux version.
What’s involved in obtaining a Linux Certification? You must pass one or more extensive tests that demonstrate your prowess in dealing with the
typical and some atypical problems faced by Linux systems administrators. We’ll take a closer look at the CompTIA Linux+™ Certification, the one often recommended as the first certification for people new to Linux. This certification does not apply to any specific Linux version. The test is designed to validate the knowledge of individuals with a minimum of six to twelve months of practical Linux experience. According to the Computing Technology Industry Association, professionals achieving the CompTIA Linux+ certification can explain fundamental management of Linux systems from the command line, demonstrate knowledge of user administration, understand file permissions, software configurations, and management of Linux-based clients, server systems, and security. Many of these functions are available on Damn Small Linux.
The Linux+ certification is a basic, entry-level certification for Linux system administrators. It is intended for people with six-months experience installing, operating and maintaining Linux operating systems. To achieve Linux+ certification, candidates must pass the 98 question Linux+ exam which covers seven areas: Planning and Implementation; Installation; Configuration; Administration; System Maintenance; Troubleshooting; and Identify, Install and Maintain System Hardware. This multiple-choice exam costs about $232 and is a good starting point for those who want to continue with other Linux certifications including those from Novell and Red Hat.
Why would anybody want to start preparing Linux certification on a limited version of Linux? The answer is simple – certification is not to be taken lightly. Don’t make a major financial and time investment unless you know that you really want to be certified and that you possess the required skill set. It’s not hard to find schools that promise you success in Linux certification and in any of their course offerings. But Linux certification may not be for you. Don’t make a major certification investment only to find that it wasn’t what you had in mind. Work your way through my tutorials including the suggestions for going further. Get your hands on a variety of Linux books. I would start with books designed for learning Linux and for running Linux systems before working with Linux certification books.
Don’t be satisfied with running computer exercises in your mind, and nodding your head at the appropriate times. To succeed you must do the exercises on a computer running Linux. Since installation is a component of all Linux Certification exams don’t stint on installing several versions of Linux on your computer. An external USB hard drive is not very expensive. Try to make friends with someone who knows better than you how to do things. Ask a lot of questions. And good luck!
And while you’re working on your certifications take a look at some of Damn Small Linux’s other advantages in our final article in this series.
Levi Reiss has authored or co-authored ten books on computers and the Internet. He loves the occasional glass of wine as exemplified by his wine websites including http://www.theworldwidewine.com – He teaches Linux and Windows operating systems plus other computer courses at an Ontario French-language community college. Visit his new website http://www.linux4windows.com which teaches you how to download and run Damn Small Linux on Windows computers, even if they are “obsolete.”





What you have to do is format your hard drive. Before you do that its always a good idea to backup everything on your console. That way you can easily restore the old settings if you encounter problems with the installation.
ways. First off, the PS3 is more powerful. In addition, the xBox requires a certain chip to run Linux, whereas the PS3 can run it without. In fact, it’s totally free to run Linux on the PS3.
well on the PS3. However, in the future, Microsoft could make a version of Windows that can run on the PS3. The rumor mill is buzzing, but there is no official word about this.
One of the more common ways to increase the available RAM (or to allocate more RAM to MySQL) is to configure the MySQL cache sizes. If your MySQL server instance is using too much memory, decrease the cache sizes. Likewise, if MySQL gets bogged down with large requests, increase the MySQL cache.
Games: there are eleven; Canfield, Freecell, Golf, Mastermind, Minesweeper, Pegged, Slide_Puzzle, Solitaire, Taipei, Thornq, and Xtris and Taiedit which is not a game, but a game editor. We will examine the first six games in this article saving the rest of them for a companion article. As with any gaming systems, be careful not to get addicted.
Mastermind is a game in which you use a mouse to drag colors from the palette (on the left) to the empty cells in the guess row. When the four cells in the guess row are full, right-click on the right of the screen to see how you did. There will be one black peg for each cell that is the correct color, and one white for a color that is not in the correct sequence. Keep going and you can eventually figure out all the colors in the row. If that’s your thing.
Firefox went to google images and downloaded into the /home/dsl directory the first crayfish image that Google offered me. Then I loaded it into the game which chopped into into pieces to be reassembled. Left-click on a tile to slide it into the adjacent empty space. Right-click to see the original image. If you are really good you won’t have to take a peek at the original image. It helps if you have chosen an image that’s easy to reconstitute. I don’t recommend crayfish.
Other factor which contributes in making Linux Web Hosting a hit among the users is that the distribution cost is very small. With this you also avail free applications to assist the server run swiftly and consistently. Some of these applications you will also very well acquainted with such as HTTP server, File Server, FTP, DNS server among various others. With the technology of PHP, it is able to produce web pages having dynamic content and is also visually attractive. Such pages can change in terms of appearance as well as content. This is mainly keeping in consideration the interest of the person watching it has to so something like getting a form filled. Another most important advantage that plays a crucial role is that it is extremely easy in terms of its scalability. The provider of Linux based services offers practically a website, small as well as large as per your needs.
I’m pretty confident that we have all seen an error or two displayed on a website. Some errors that are displayed are not a security issue at all, for instance Javascript errors. However, some errors are security issues (PHP is particularly bad with this), because they disclose sensitive information. The easiest way around this is to disable displaying errors in PHP (or your web applications). Otherwise, an attacker may be given information about your website’s database details, or file locations.
Each company offers similar packages which include add-ons like support for programming languages such as PHP, ASP, Perl, database support such as MySQL or even a shopping cart for those of you interested in selling items from your website. If you have a need there is probably a company able to meet it for you and if not you may have just found yourself a business opportunity.
Apache is an open source software that is free for everyone to use and the best place I’ve found for downloading the program is ApacheFriends.org.
