When you are a new user needing to get Linux training, it is often confusing to decide what to focus on.

Should you learn how to use Linux for just one distribution (a.k.a. version, distro)?

Should you focus on learning GUI utilities – or should you learn Linux commands for doing system administration?

Linux Commands Training Tips: The Linux System Administration concepts and commands covered here apply to ALL Linux distros, including: Red Hat, Ubuntu, Kubuntu, Edubuntu, Slackware, Debian, Fedora, SUSE and openSUSE.

3 Methods of Linux System Administration and Why Using Linux Commands is the Best Method

1. Using Linux GUI utilities for System Administration

Many Linux distributions have “point-and-click” GUI (graphical user interface) utilities that allow you to do common and popular tasks, like manage the file system, create Linux users, and manage user and group permissions.

However, these GUI utilities are usually specific to a single Linux distribution.

So, learning how to use a Linux GUI in one distro is basically useless if you have to use a different one later, or if you’re working in an environment with multiple Linux distributions.

Linux Training Tips: To run a GUI utility, you need to have a desktop installed and sometimes one isn’t installed on a Linux server because it isn’t needed. In addition to this, the Linux system administration pros only use commands because GUI utilities are too slow to run and time-consuming to use.

2. Doing Linux System Administration Tasks with Commands that are Specific to a Distribution

The major (popular) Linux distributions all have several commands that are specific to that single distribution. In other words, for each popular distro, there are several commands that are specific that just that version.

For example, a Linux distribution will likely have a command that is used to manage partitions (disk space) and this command is specific to that distribution.

Learning how to use commands that are only available on a single distribution is a huge waste of time – if there is an equivalent GNU / Linux command – and there almost always is.

For example, the Linux fdisk command is a GNU command that is used to manage the partitions on a system and this command exists on all distributions.

So, rather than learn a command that is specific to a single Linux distribution, learn the GNU commands because these commands are common to all distributions.

3. Using Linux Commands that are Common to All Distributions – The GNU Commands

The GNU commands are the most popular Linux commands – and they are common to all distributions.

Linux Training Tips: Linux distributions are rising and falling in popularity all the time.

If you just learn how to use Linux by running the GUI utilities in one distro, and then you stop using that distro, then you have to learn all the GUI utilities of the next distro. If you learn how to use commands, then you learn how to use Linux for all distros!

How can you tell which commands are the GNU / Linux commands?

Get an excellent set of videos that shows you the popular GNU commands and then try these Linux commands yourself. Then you can learn Linux the easy way – by watching it and then working with it!

And now I would like to offer you free access to my Linux Commands Training Mini-Course, a 7 Lesson, Daily Mini-Course, including the free Linux Commands ebook and Linux audio podcasts – showing you how to get started learning how to use Linux commands.

Three Reasons To Use Linux For Home Use

By Anand V Parekh

Back in pre Ubuntu days, using Linux for personal use was somewhat like a hobby for computer programmers or the very geeky.

Not anymore. With the release of Ubuntu, a broader user base started using Linux and not just because it was released as a free OS meant for all.

Here are three reasons to use Linux for your home use:

1. Low hardware requirements: One doesn’t need the latest computer to use Linux. If your only reason to use computers is to surf the internet, check emails, make office documents and play lightweight games like Windows soltaire, older computers running Linux will do just fine. If you have some old spare PCs lying around, they can be configured as something cool like a gateway or a FTP server for home office (if there is lots of disk space) by running Linux.

2. Less dependent on tech support : As surprising as it sounds, using Linux means not relying too much on a phone call to some remote location to fix your problems. This is a great learning ground for the tinkering types with many internet forums offering free and high quality help for all sorts of Linux problems. This is because Linux is open source and so you don’t really have to rely upon a single company for your needs.

3. Awesome security: To be fair, Windows 7 has greatly improved upon user as well as system wide security. Linux on the other hand being open source can be configured in any way to make it secure – total freedom to use. There are no setup wizards for most part when configuring Linux security but in return you get solid granular security by editing various configuration files and fine tuning your system.

So does this mean you should completely dump Windows in favor of Linux? Of course not, either dual boot and use both the OSes or run a virtualization program like VMWare or VirtualBox to experience the best of both the worlds. This will be useful when you need to run native Windows applications as well as switch over to Linux when not needed. Most of the commonly used Windows applications like Office and Outlook have their Linux counterparts in OpenOffice, Thunderbird etc.

Either way, don’t miss out on experiencing Linux. Start with the widely used desktop OSes like Ubuntu or Linux Mint and see if it really proves useful for your computing needs, you may be pleasantly surprised.

The author is a tech enthusiast, systems administrator and a computer geek who got his first computer back in 1994 and fell in love with it. He blogs at ihaveapc.com regarding various stuff related to Windows and Linux.

Virtual Desktop Infrastructure (VDI) With Ubuntu Linux
By Alex Colcernian

Looking to deploy Virtual Desktop Infrastructure (VDI) with Ubuntu Linux?

Virtual desktop infrastructure with Ubuntu Linux is ideal for anyone who is concerned about security of WAN based VDI. It is also perfect for organizations hosting their applications in the cloud, utilizing software-as-a-service through a web browser. VDI with Ubuntu Linux eliminates the maintenance of desktop devices, and reduces the number of hard drives in your IT footprint.

Linux Terminal Server Project (LTSP) allows the centralized deployment of virtual desktops on a local area network. Virtual desktop devices (thin clients) are connected to a switch on the LAN which connects to a server or cluster of servers delivering a desktop environment and applications.

LTSP is integrated into Ubuntu 11.04 and earlier versions. The logical choice for deployment is Ubuntu 10.04, a LTS version. LTS stands for long term support, which provides three years of security and maintenance updates.

Low Cost VDI with Ubuntu Linux

With LTSP organizations can recycle old Desktop PCs (800 MHz, 256MB RAM) or deploy new low footprint and energy efficient thin clients. A properly sized quad-core server could power up to 50 thin clients, providing desktop environments at a relatively low cost. Cost savings are most notable in maintenance and security over the years. Desktop hardware refresh cycles are between 7 and 10 years, thanks to the lack of spinning hard drive in each desktop device. Backups take place only in the server room. Desktop device replacement is as simple as drop in and power on (unless you have security customizations).

LTSP Technical Overview

Thin client devices in a virtual desktop deployment with Ubuntu Linux boot over your local area network. The virtual desktop environment and applications are executed on the server in a read only format. Users are still able to customize their desktop’s as well as access personal and shared fire storage. Applications can be delivered from local or remote application servers and can be Windows or Linux based.

Security is greatly increased with stateless operation of the virtual clients operating with a ssh connection between client and server. User storage can be moved to a SAN type solution, moving the VDI server another step away from risky IT files. Since this solution is over a local area network the concerns of sending sensitive data over the WAN are not present. User’s do not have access to make any changes to any server settings. USB devices can be disabled for all thin clients on the network.

Who’s Using LTSP Today?

LTSP is used by major public and private universities, Fortune 500 companies, government entities, charter schools, small and medium businesses, franchised retail stores and more. It is a versatile solution which allows for desktop delivery customization, network segmentation, and user control. Consult an experienced professional for more advice in deploying LTSP with Ubuntu Linux.

Alex Colcernian is the Director of Marketing and Sales at DisklessWorkstations.com. DisklessWorkstations.com founded alongside the Linux Terminal Server Project (LTSP) in 1999, provides thin client hardware and solutions. DisklessWorkstations.com is the global leader in LTSP deployments, serving businesses, government, non-profits, and schools. For more information, please visit http://www.DisklessWorkstations.com.

Automatic Installs of Turnkey Linux Appliances on Virtual Private Servers

By Marc Warne

(Or How to set up a fully working Joomla, Drupal, LAMP, LAPP, Zimbra, Torrent server etc., in a couple of minutes)

Turnkey Linux comprises a set of free, Ubuntu-based software appliances that are primarily available for server-type usage scenarios, such as setting up database, web, forum, wiki and photo gallery servers. Each appliance is preconfigured to work out of the box, with ease of use being the primary goal behind the Turnkey Linux project.

This is extremely useful in itself, but if you wanted to experiment with these appliances, potentially to evaluate or otherwise test them, it would be great if you could perform installations with the absolute minimum of effort.

Using Turnkey Linux on Virtual Private Servers

A number of hosting providers out there provide Linux VPS services, which usually enable users to have their own virtual server with automatic provisioning of major Linux distributions, such as Debian, Ubuntu or CentOS. Work has been performed in conjunction with the Turnkey Linux team and has managed to take the automatic installation concept one step further to enable this to work with all Turnkey Linux appliances. This is made possible by using frameworks provided by the excellent server open source control panel, DTC.

Turnkey Linux appliances enable users to easily deploy primarily web-based applications within an entire Linux kernel and Ubuntu-based package set. Once a distribution is chosen within the control panel, the install is fully completed within a few minutes and ready to be customised. This enables a rapid deployment of a tested setup, with full update and security support provided by the Turnkey Linux and Ubuntu package maintainers.

Our efforts are available to all using the DTC control panel, with Debian packages for Lenny being provided. Additionally, scripts have been written such that when new or updated appliances are released, new deployable packages for the DTC control panel are created and made available in our repository automatically.

Technical Script Details

It is not actually too difficult to configure images to work for automatic deployment, but performing this manually for every appliance is a time consuming process. The scripts we have written will automatically perform the following steps for each appliance:

  1. Create a new directory with a name similar to the actual release version, e.g. turnkey-core-2009.02-hardy-x86.
  2. Copy across common template files. These include the following:
    • custom_os: Customises each appliance by configuring basic networking, spawning gettys on the right devices and setting a customised MOTD with the VPS number and hostname.
    • install_os: Custom instructions to install this appliance, which essentially involves untaring the provided image into the VPS.
    • setup_network: Custom instructions called when setting up the network. Because Turnkey Linux uses resolveconf for DNS configuration, this reads information from /etc/resolv.conf from the dom0 (this is designed for use with Xen) and copies it to /etc/network/interfaces in the domU.
    • debian/*: These are the files changelog, control, compat, copyright, files, install and rules which are required to create a.deb packages. These have substitution variables (e.g. for the package name) which are overwritten by our script.
  3. Copy the preinstalled image (a.tar.bz2 file).
  4. Tailor the template files (as above).
  5. Invoke dpkg-buildpackage in this directory to create the actual.deb file.
  6. Call reprepro, a tool we use to manage Debian repository directory structures, to remove old versions of this appliance and add the new one.

It’s as simple as that. If you are interested, the raw scripts are downloadable. They will need some customisation for your setup as there are hard coded directories in there.

I want to play with one!

If you are happy playing with just one appliance, you can of course just download it from the Turnkey Linux website and install it on your PC (or use a Virtualisation solution like Xen or VMWare).

However, if you want to rapidly try out a variety of appliances using the setup we have made, the quickest way would be to rent a VPS. Alternately, you can install the DTC control panel yourself and add our Debian repository to your /etc/apt/sources.list. This setup requires you to run a fully featured Xen setup and requires significant configuration.

2011 Best Linux Distributions

By Judith Ceja

Which Linux distribution is right for you? There is no one right answer because it depends on your experience and specific needs. Listed below are the top seven Linux operating systems for 2011. Each program was ranked based on ease of installation, user-friendliness, and amount of support available.

Ubuntu is one of the most popular Linux distributions for desktops. New versions are released about every six months. This program is easy to install and use. The ample support comes from both technical professionals as well as end users. Ubuntu is a great program for beginners

Mandriva originally appeared to be a restructured version of Red Hat Linux. The current software has added user-friendly features including better hardware detection and intuitive disk partitioning. Mandriva also utilizes a KDE desktop and has great support which makes it a good program for beginners.

PCLinuxOS is great for new Linux users due to its intuitive graphical installer. It provides users with current desktop software and fast boot times. This program received our lowest rating for support because it does not provide support in any language other than English. Additionally, the program is only available in a 32-bit version and new releases are not scheduled regularly.

Gentoo was designed for power users, allowing them to have ultimate customization capabilities. It also has exceptional security. One of its best features is the ability to keep the system current without re-installing the software. However, long compilation times and occasionally instability makes it less of a crowd pleaser than other available software.

OpenSUSE has an extensive and intuitive configuration tool. The program also includes user-friendly desktop environments (GNOME and KDE). The program gets high marks for help and support. However, its heavy use of resources for desktop setup and graphical utilities tend to slow the program down.

Debian GNU/Linux supports more infrastructures than any other Linux distribution program and contains more than 20,000 software packages. It has become the largest Linux distribution ever created and has inspired over 120 Debian-based distributions. The program has a reputation for stability and being the most bug-free Linux distribution system on the market. However, their intensive testing has led to lengthy intervals between releases, typically 1-3 years.

FreeBSD was introduced into the market in 1993. The program is not in the same league as the other programs listed. However, it is fast, stable and has over 15,000 software applications available. FreeBSD lacks a graphical installer and the convenient features of hardware detection and system configuration which must be performed manually by the user.

Ultimately, you must choose the program that is right for you. Ubuntu and PCLinuxOS enable beginners to use Linux without requiring a steep learning curve to produce results. Gentoo and FreeBSD are definitely for more advanced users. Mandriva, Debian GNU/Linux, and openSUSE are the best programs if you are willing to trade some advanced features for stability and continuing support.

Linux Vs. Windows

Windows Vs Ubuntu

By: Cameron Craig

This topic has had a lot of controversy over the years but it is time to dive into it head first.

When many people hear the word “Linux” they immediately think of  an operating system that is strictly used by computer hackers, computer programmers or people that are incredibly computer savvy.  Although these things are true, Linux operating systems are starting to steer further and further away from this stereotype.  To the right are logo’s of both Windows® and Ubuntu, a popular distribution of Linux.  If this image was shown to the majority of people that use a computer they will not only not know what the Ubuntu logo is, but they will recognize the Windows® logo first due to their commercial success.  It is becoming more and more obvious that people are starting to be less and less intimidated by Linux OS’s which is why the heading of this post is more significant today than it would have been 10 years ago.

With the release of Ubuntu 10.04 (now up to ver. 10.10) came a cult following of people that want to know more about “The Desktop Linux”.

Top 10 Pages Hit at Distrowatch.com

Distrowatch.com is a very popular location to read up on and download various distributions of Linux.  As you can see from the picture on the left, Ubuntu is ranked 1st among the other top 10 distro’s.  If you go to Distrowatch.com almost the entire homepage is dedicated to different versions of Ubuntu.  Ubuntu is starting to become the “Windows®” of the Linux world.

Now that we have touched based with Windows® and Ubuntu lets get a little deeper by talking about how they both operate and function:

Any bench test will show you that hardware will give better performance in Ubuntu than Windows 7 but this is not the only advantage of Linux over Windows® 7.  Virus’ are aimed mainly at Windows® users because A.) it is the most commonly used Operating System and B.) it is relatively easy to get unwanted software to be downloaded and run on Windows® platforms as opposed to a Linux or Macintosh® platform.  Perhaps hardware performance isn’t of much importance to you, perhaps you are willing to sacrifice performance and security for a GUI that is so commercial.  You could put the average computer user in front of a machine with a distro of Ubuntu on it and they will not know how to navigate or use the system nor will they want to learn how; but if you put that same user that has only had experience in Windows® XP in front of a machine with Windows 7 on it, they will be a little lost but will be WILLING to learn how to navigate and use this system even though it is relatively native to them.  Why?  Because over the years Windows® has won over the computer market with commercial success and as long as people see that Windows® logo at the bottom left hand corner of the screen they feel safe and secure.  The best choice is obvious, but why don’t people make the best choice in their choice of operating system?  Because they are ignorant to what Linux can offer them.  Linux is no longer just for the computer elite, it is for anyone and everyone that has the desire to have a powerful yet easy to use platform at their fingertips.

It is starting to become more and more obvious that Windows® is not the best OS to use and hasn’t been for many years now. Does anyone but me find it funny that Microsoft© offers both x86 and x64 images of Windows 7 available for download DIRECTLY FROM MICROSOFT.COM that you can LEGALLY use for 30 days without the need for activation? As if pirating software was not easy enough… Could it be that Microsoft© is FINALLY embracing the fact that no one will ever be able to stop pirating?  Or could it be that they are starting to go the route of Ubuntu with the philosophy of “Desktop Operating Systems should be free of charge”?

No longer are people intimidated by Linux, no longer are people afraid how to navigate and use Linux and the evidence of this is everywhere!  The developers offer tutorials on how to use their software WITH THE FREE DOWNLOAD of their operating system!

Whether you just use the computer to surf the internet, check e-mails, listen to music or do vulnerability scans on specific networks,

L I N U X IS FOR YOU!

Installing Programs in Linux – It’s No Longer Difficult

By S Austin

There are quite a few myths that are still common today about the Linux operating system. One of these myths is that programs are very difficult to install.

There was a time in Linux when you had to do something called compiling a program. This involved going to the terminal and manually installing all of the files. If you did this incorrectly, the program would not load. If you needed another program installed to make this one work, you would have no idea what to do. You had to do intensive research to make sure you had all the dependencies installed. It really a serious pain and much too difficult for even an expert computer user.

This misery is still remembered by many who will tell others that installing programs in Linux is simply too hard to do. Today, after about a decade of improvements (which in computer years is quite a bit) installing programs in Linux is easy. In fact, it might be easier than what most people are used to with their current systems.

Most versions of Linux have some sort of package manager. This means that a group of people have checked certain programs to make sure they work, maintain all the updates for you, and make sure all the dependencies will install when you want to put an application on your computer.

In Ubuntu, you open the Applications menu and click on Add/Remove. Search for the program you want to install. Check a box. Then hit Apply Changes. That’s it. As you can see, this is a very simple process. To remove the program you just uncheck the box and hit Apply Changes and it’s gone. That’s easy enough for almost anyone to do. Additionally, you know these packages and programs are safe for your computer since a human being has manually approved them for your computer.

Whether using Linux or your operating system of choice, make sure to get the best business web hosting available. Don’t take chances with your business website.
