Whilst Microsoft still dominates on the desktop, Linux has a huge user base in business as a server operating system. Red Hat LinuxAlmost all of the worlds major websites run on Linux – Google, Facebook, YouTube, Wikipedia to name just a few. It’s therefore no surprise that there is a growing demand for professionals with Linux skills, who can command up to 30% higher pay than their Microsoft-supporting counterparts.

Red Hat Enterprise Linux (RHEL) is the most popular Linux distribution amongst medium to large enterprises, and Red Hat have developed their own training courses and certifications to ensure that professional standards are high.

There are three levels of certification provided by RedHat – RHCT (Red Hat Certified Technician), RHCE (Red Hat Certified Engineer) and RHCA (Red Hat Certified Architect).

RHCT is the entry-level certification, suitable for a junior-level system administrator looking after Linux systems. Topics covered include package management, network configuration, file system administration and basic system troubleshooting.

RHCE is a well respected qualification, which shows a good level of knowledge of use and troubleshooting of Red Hat Enterprise. Topics covered include advanced package management, system services, kernel configuration, network configuration, advanced account management, web services, mail services, virtualization, NFS and troubleshooting.

RHCA is a very difficult to attain qualification, currently held by less than 1000 people worldwide. To attain the RHCA qualification, one must pass a total of six exams – the RCHE exam; RedHat Enterprise Security: Network Services, RedHat Enerprise Deployment, Virtualization and Systems Management; RedHat Directory Services and Authentication; RedHat Enterprise Clustering and Storage Management; and RedHat Enterprise Systems Monitoring and Performance Tuning Expertise. Those who attain RHCA qualification can expect to find themselves in high demand, and command a sizeable salary.

For those unfamiliar with Linux, the RHCT is a good initial goal to aim for. RHCT certification provides a good ‘foot in the door’ for would-be employees looking to impress an employer and gain their first Linux System Administration job.

For those looking to run an entire network, RHCE certification should be sought. The RHCE course provides a good level of knowledge, enough to be able to cope with most challenges day-to-day administration can throw at them. The RHCE exam proves a high level of knowledge, and is a highly respected qualification.

RHCA certification should only be pursued by those hoping to forge a career as a professional Linux consultant and/or troubleshooter. Together, the examinations that make up the certification represent more than 30 hours of test time – to say nothing of the preparation time required. As such, RHCA certification is only for the most dedicated and studious of people.

Linux Training and Red Hat Certification

By John Kol Marsh

In today’s competitive IT world, knowledge of Linux can help shape the future of a person. Apart from knowledge in languages such as Java, C++,.net, PHP, knowledge of Linux can help in securing a very good career. Linux was created by Linus Torvalds. The source code of Linux which is called the Kernel is available for free on the internet. Anyone can download and develop it in a unique way. Many companies have already released their own versions of Linux. This makes it a very unique operating system. Every version of Linux is different from the other in one way or the other.

Linux is one of the preferred operating systems for corporate houses.

· One of the greatest advantages of using it is because it’s swift in multitasking. It is very stable in terms of crashing and rebooting. Many other operating systems have to be rebooted from time to time to run efficiently.

· As it is a free-operating system, the bugs are fixed within a very short span of time. If a bug is reported, many people will offer solution to the problem like a community based approach.

· It is secured operating system because of the fact that it is virus-free. This is because it does not recognize or run the virus or worms.

This makes it a perfect operating system for corporate and databases.

Linux training can help in gaining sufficient knowledge about Linux. It is different from the most popular operating system like Microsoft Windows. There are many variations in Linux and one of the most popular versions is Red Hat Linux.

In order that a person needs to fully understand and operate a Linux based system, he or she needs to have required knowledge and training. Red Hat Certification or RHCE Certification is the certificate which is given to those expert users who get through the Red Hat Training and Examinations. Red Hat Training includes Red Hat Essentials, System Administration, Security & Networking Administration, Red Hat Enterprise Linux Virtualization.

Now the question of which professional institute to choose arises. There are plenty of institutes that provide Red Hat Linux. But, one of the best Corporate Linux Training provider is Zonix Systems. Zonix systems has scaled up to the position of a leading Linux Corporate Training providers within a short span of time. The reasons are the course curriculum that they follow and the Team Members.

Linux Certifications – How Valuable?
By J Reece

Computer certifications in general

Acquiring certification indicates that you have completed the steps and have the knowledge required to perform at a specified level as an IT professional. Certification also proves to your employer and clients that your expertise is confirmed by a recognized industry organization and can increase your salary, enhance your skills and make your job more satisfying. If nothing else, it can keep your resume from being rejected by the resume-scanning programs now used by every Human Resources department these days.

Why a Linux certification?

The number of job ads calling for some knowledge of Linux has risen by nearly 100% over the last year. On the other hand the number of applicants choosing Linux certification hasn’t risen proportionally. Part of the reason for this anomaly is that employers generally haven’t put much faith in Linux certifications and therefore there has been little demand for them. Also, many of the Linux jobs advertised are for more senior and technical roles such as programmers and developers – skills that far outweigh the level that are tested on some Linux certification tracks. All that appears to be changing however, with Linux becoming ever more mainstream and people with Linux skills becoming more in demand.

Will Linux certification really help?

While actual work experience with Linux or any computer technology will always count for so much more than any piece of paper, gaining Linux certification certainly won’t do your credentials any harm. The demand for credentials in every field, computer-related or not, is increasing and one has to keep up with the pack. Having that certification ticket punched may not make your resume stand out in a positive way, but not having it might make it stand out in a negative one. Large bureaucratic IT organizations take them more seriously than groovy startups if that’s the environment you’re looking to work for. There are several specific situations where I’ve found computer certification in general to be of benefit. First, certification courses offer better knowledge retention than the typical corporate training course since you do have to study to pass an exam, even if only a multiple-choice one. Another one is where you have related experience and are moving (or were moved) into a new environment. In my case I was re-orged from a Unix-centric to a Windows-centric IT environment. Getting a Microsoft System Administrator certainly helped come review time. Finally, if you have a discrimination issue, such as the common one that as an older tech worker you’re skills aren’t up to date. If push comes to legal shove human relations people, lawyers, and judges do take evidence of continuing education very seriously.

Which Linux certification?

There are several options to choose from and, given the amount of time and money that you’ll need to invest into gaining your Linux certification, you’ll want to be sure that you make the right certification track choice to begin with. For those new to Linux then the entry-level, vendor-neutral certifications offered by CompTIA and LPI an appropriate choice. However, these involve only multiple-choice tests and as a result have rather less credibility with technical managers. If you are already working with Linux then one of the proprietary, more difficult, and more expensive Linux certifications (Red Hat, Novell) would be better suited. Like the respected Cisco certifications these certs involve rigorous hands-on practical exercises under severe time constraints and have much more credibility with technical managers. The cost is significant, especially if you have to retake the test, as almost 50% of Red Hat wannabes fail the first time around. Given that there are numerous distributions of Linux available one problem of Linux certifications is that there is no central organization that can set the certification standards and ensure that the candidates meet those standards. What this means is that you have quite a degree of freedom to choose which certification track is right for you, but you equally need to be sure that the one you choose will meet your end needs. As with any other certification track that you take, Linux certifications can be taken by way of instructor led courses or you can undertake a regime of self-study on your own. Don’t get too bogged down on deciding which distribution is better or is more likely to result in a job at the end of the day. While there are obvious differences between the various Linux distributions a degree of competency in one flavour will set you up to transition to the others if need be at a later stage.

Easy Linux Training – Linux Tips on Using Multiple Options with a Linux Command
By Clyde E. Boom

Linux distributions (versions), especially the major Linux distros, include several “point-and-click” Linux GUI utilities. These utilities can be used to do Linux administration task. However, you have to do an awful lot of pointing and clicking to get anything done in these Linux GUI utilities.

What takes several clicks (and way too much time) with a Linux GUI utility can be done almost instantly by running a Linux command. However, new Linux users usually find Linux commands tricky to learn – but they are well worth learning. Also, if you are working on some kind of Linux certification, you will get tested on Linux commands, not on Linux GUI utilities.

Another benefit of learning Linux commands is that they are virtually identical on all 130 + Linux distributions. So, the best way to learn how to use Linux, to do Linux system administration, is to learn how to use Linux commands.

Linux tips: When you get Linux training, including Linux certification training, be sure to learn how to use Linux commands. Don’t waste time learning Linux GUI utilities.

Linux Tips – How to Use Multiple Options with a Linux Command

1. Most Linux commands have several options.

Linux command options are used to control the output of a Linux command – and some Linux commands have over 50 options!

2. For almost all Linux commands, the options are prefixed with a – (dash).

For example, the following Linux command runs the ls command with the l (el) option. The l stands for “long” and it gives you a longer (and more detailed) listing of files and directories in the Linux file system.

]#   ls  -l

Linux Tips: In these examples, the ]# represents the Linux command line prompt. You don’t type in the prompt!

3. Linux command options can be combined.

The ls command is used to list the directories and files in the Linux file system. It has an l (for long) option and an a (for all) option. The a option shows “all” files, including hidden files.

The following command uses the l and a options to give you a long listing of all files.

]#   ls  -l -a

4. Linux command options can be combined without a space between them and with a single – (dash).

The following command is a faster way to use the l and a options and gives the same output as the Linux command shown above.

]#   ls  -la

5. The letter used for a Linux command option may be different from one command to another.

For example the -r option of one command may not provide the same output as the -r option for another command.

You can learn how to use Linux commands easily by watching Linux video tutorials.

When you watch a Linux video tutorial, you get to see, hear and do! You get to watch the command being typed in and hear an explanation of why you run the Linux command. Then you can pause the video tutorial and run the Linux command yourself!

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.”
