How to Pass the Linux+ Certification Exam

Linux+ certification is the brain child of the Computing Technology Industry Association which is commonly known as CompTIA. The Linux+ certification is termed as a vendor neutral certification exam as it is not one that complies with a particular retailer’s software or hardware. This exam is considered to be the most different type of examination when we talk about the Information technology industry. There are lots of certified programs of IT companies like Novell’s Certified Novell Engineer (CNE) certification, Red Hat’s Certified Engineer Certification (RHCE) etc that are dealing with a particular vendor’s hardware or software.
An individual’s knowledge and skill level on the Linux operating system is tested when one takes the Linux+ certification exam. The certificate holder will be an expert in software configurations, management of Linux-based systems, its servers and security, understanding file permissions and indicating knowledge of user administration. All the aspects pertaining to Linux operating …

An Introduction to Linux Shell Commands

The Linux system often intimidates beginners, what with the need to type in a command or two every now and then. However, Linux commands (or shell commands, to put it more accurately) follow a rather logical and sensible pattern and all you need to do is get used to it! Most shell commands are roughly 3, or at most 4 letters long. The more frequently needed commands are shortened further usually.
The man command is a reference to ‘manual’, i.e. the documentation that comes preloaded in Linux systems to help you with common problems faced by a user. These man(ual) pages are certainly not meant to be standalone guides for beginners, but instead, they need to be used as reference material to corroborate what you’ve learnt/tried elsewhere.
The info command is another way to look up reference material for GNU information and troubleshooting suggestions. It isn’t completely the same as …

Aged Security Flaw Renews Open/Closed-Source Debate

The recent announcement of a 13-year old security flaw found in an Open Source security library has renewed the debate between open source and closed source software. The library, crypt_blowfish, allows for fast two-way password encryption. The flaw introduces the potential for passwords to be easily compromised and affects PHP and a number of Linux distributions that include the crypt_blowfish library.
As with most security bug announcements both the Linux/Open Source and Microsoft/Closed Source supporters began pointing fingers at each other on several news sites and blogs, with the occasional troll tossing in a flaming comment just to keep emotions high. Unfortunately this type of debate rarely does anything to move the industry or community closer to more secure software deployments.
In handling aged security flaws such as this it is important to put aside emotion and focus on the issue. Security issues involving a broadly deployed code base require …

Learn How to Use Linux?

Linux is an operating system that is created by Linus Torvalds. It all began with his interest in a small UNIX system called Minix. In course of time, Linux came to become a fully functioning operating system and in 1994, version 1.0 of Linux kernel was released. The heart of the Linux system is the Kernel. The kernel is that part of the system that servers as the communication link between the machine’s hardware and software. Since the time of its initial development, Linux’s kernel has increased in its complexity. Linux is open source software and its source code is available for everyone.
Linux is versatile software that can be deployed as a web server as well as used in individual systems. Linux is robust software and Linux web servers have been running for more than a year, without the need for re-booting. This also ensures cost effectiveness and as …
