Key Comparisons of Linux Vs Windows Servers

July 16th, 2010

Everyone who is fairly new to web hosting, choosing the platform you are going to use for your server can be uneasy and even mind-bottling decision. Although there are several obscure choices still available, the most widely used Operating Systems (OSs) are the enterprise, or server, versions of Linux and Windows.

There seems to be a wide source of information regarding hosting, but it seems that the waters have been muddied by many authors' self-important personal opinions. This has resulted in some of the issues becoming rather unclear to intermediate users. Some technology bloggers have put quite a few hours, even years, into research on the subject, only to conclude that it really doesn't matter what server you decide to use. They claim that you should just make sure to choose a really good web hosting, instead of worrying about the type of server software they are running.

Are they right? Does it matter what kind of server hosts your site? Why? What is the difference between the two OSs, anyway?

Cost considerations

Microsoft manufactures and owns the rights to the entire Windows OS, from the recently retired XP to various flavors of Vista. Linux, on the other hand, is “open source” software and is usually free. What that means is that it can be more costly to install and run a Windows server, but this really would not affect you unless you are setting up the server personally – and if your eyes are glued to this article then it's a safe assumption that you are not doing so.

What this article will do for you is give you the rundown on how to make the right decision about the web-hosting server you choose. The costs inherent in running a server do not always affect the price of the hosting package as you might suspect. The fact that a single Windows server would be more costly to set up and run doesn't apply to a web-hosting firm that has installed several dozen or more. Getting the Window hosting package is usually a bit more expensive than the Linux hosting package, but not so much that you should disqualify it on price alone.

Make no assumptions

Individuals often assume that just because their PC operates on Windows, they should purchase a Windows hosting package. Not necessarily. Gaining access to your web account will usually be done through FTP or a control panel, and all servers support these methods. The most important difference in administrative site access is that some FTP commands are a bit different in Linux than in Windows and, of course, the FTP programs will usually be created for only one or the other.

Think about how you intend to put the server to use. Make your decision based on those facts. The web features that will run just fine on both platforms include PHP and the e-mail protocols, IMAP and POP. On the other hand, using ASP, Frontpage, the .Net environment, Access, Windows Streaming Media or other Microsoft technologies will likely require a Windows host. Linux offers only limited support, or none at all, when it comes to these technologies, meaning your “workaround cost” will be quite high and may lack the features you need.

Stability and growth

Different server platforms' reliability and stability records have been raised in many discussions, some rather contentious. The focus of many anti-MS rants has been that Windows is not a secure environment and is only popular because it is the OS for the majority of home-based PCs. As the most commonly used system, Windows has flaws and people tend to spend a lot of time looking for them, as well as exploiting them for harm.

However, Linux may just be the most common server type out there and, surprisingly, the success rate for hackers has been higher than expected, although not as high as for Windows. After all is said and done, the platforms and their security boil down to systems administration and server company management. If security is the main focus for you, then be sure to take the time to investigate the company that is hosting your site. Make sure that they have a reputation that is corroborated by other companies, not just their own marketing materials. This way you will have fewer worries about the server you are using.

Too close to call?

When it comes to the performance of the two servers, there is not a huge difference. Linux has been known to perform faster than Windows on some “cookie cutter” hosts that install Windows in its default, “all in one” package. Linux distributors, using an open-source application with more flexibility, can implement “extensible” packages with greater customizability. In normal situations, the performance of the two is comparable, but if system functionality is most important to you, this may have an impact on your final decision. Which direction that will send you depends on what you wish to compare, as the OSs do have some different strengths and weaknesses.

It is arguably a better use of your time to look for a good host rather than a good server model or OS. Linux and Windows developers are always working on ways to improve both systems. At this point they seem to be roughly equivalent when it comes to the security, features and reliability expected by the average home and small business user. This is not likely to change for some time. You must base your decision on the factors most important to you and your business, and in this neck-and-neck horse race, a clear winner is impossible to call. Eventually you will just have to saddle up with one or the other, and hit the track.

 Reason To Learn Linux – It Runs On Obsolete Computers

July 12th, 2010

Several years ago the Utah Department of Environmental Quality estimated that by 2004 more than 300 million computers would be considered obsolete, generating well over 1 billion pounds of lead, 2 million pounds of cadmium, 1 million pounds of chromium, and 400,000 pounds of mercury. Municipal incineration is the largest point source of dioxins into the US and Canadian environments and among the largest sources of heavy metal contamination of the atmosphere. Of course the year 2004 is long gone, and these horrible numbers have undoubtedly been far surpassed in spite of efforts such as corporate trade-in programs.

When it comes to the environment do you want to be part of the solution and not part of the problem? If you do not want to be part of the problem avoid tossing that supposedly old computer onto a landfill. Did you know that your outcast computer remains will take decades to biodegrade and leach scads of poisonous chemicals into the environment during the process?

Why do everybody toss their computers? That is simple; given the computer industry's unending performance advances there is a widespread perception that you can no longer DO anything worthwhile with your outdated computers. This dangerous assumption is simply not true.

Do you really need Giga-everythings to get your work done and have your fun? Microsoft seems to think so. I remember when 128 Megabytes was a lot of memory. Of course I also remember when “Why would anyone ever need more than 640 Kilobytes of memory?” was the official party line expressed by none other than William Gates III himself.

I'm told that Damn Small Linux requires only 50 Megabytes of disk space, a 486 processor (do you remember what that is?) and 8 Megabytes of RAM. If you want to browse the Internet, you'll have to move up to 16 Megabytes of RAM and use the Dillo browser. The popular Firefox browser requires additional memory. Frankly, I wouldn't use such an underpowered computer for moderate or heavy Internet usage. But you can run Linux commands and learn how operating systems work on such computers. And you can play a multitude of games.

For every individual trying to resuscitate a 486 computer there are dozens trying to know what to do with an old Pentium such as my Pentium III 450 Megahertz computers with 128 Megabytes of memory purchased in 1999 or more powerful computers purchased several years later. Without extensive upgrades many of these computers won't run Windows Vista and may not run Windows XP. But they will run Damn Small Linux or other Linux versions alongside a full range of today's applications. Let's put them to work, learn Linux, and do our bit saving the environment.

We next see how Linux lets you control the computer, “obsolete” or not.

Linux Commands Quick Tips – Using the Sudo Command 

July 8th, 2010

Regular Ubuntu Linux Users and the (Lack of Use of the) root User

When you install Ubuntu Linux, you create a user, which is the “first” user and you can also create more users if you need to. When you create the “first” user, you assign this user a password – and this one is very important!

It is required to log in to the desktop (at the Linux GUI login prompt) as the “regular” (non-root) user – and this password is also required to be able to do the equivalent of logging in as the root user – when you're working at the Linux prompt a terminal emulation window on the desktop.

By default, the root use is not “enabled” (not available) in Ubuntu and so you can't log in as this user – which is an innovative thing – as it stops anyone from logging in to the desktop as this user – which should never be done!

Example of Running the Linux sudo Command – To Start Working as the root User

You type in:   sudo -i   and then press Enter to change from working as a “regular” user to working as (the equivalent of) the root user in Ubuntu (and variations or derivatives, such as Kubuntu – see more on this further below).

And then you provide the password of the first user that was created on the system. After running the Linux sudo command, the prompt changes from a dollar sign to a number or hash sign (press Shift 3). To “go back” to working as a “regular”, run the exit command by entering the command name and pressing the Enter key.

This Linux version has its own “derivatives” (variations), and many of these end in “ubuntu”, such as Kubuntu.

    Linux Commands Training Tips: The “K” in Kubuntu stands for “KDE” – it is the “K” in “KDE”, for the KDE desktop.

    The Ubuntu distro uses the GNOME desktop by default and Kubuntu uses the KDE desktop by default.

Ubuntu Linux and it's derivatives are some of the few distributions that require the use of the sudo command with the -i option as shown above – as opposed to using the su command with the – “dash” option and then typing in the password of the root user.

If you love linux, then you would try this for free rather than buying expensive licensed OS.

Image via Wikipedia

Linux is an Open source operating system that widely use by many user. Linux known as open source operating system that means you can download all the source code and write your own. By using open source technic or copy left, linux by itself becoming more and more famous. Many people around the world helping each other to make linux a better operating system.

Until now linux development is still going on. We can see so many linux variant each one has their own power to their users. For example many student rely their PC on linux since the cost of operating system license is too expensive. Many company start migrating their systems to Linux environment as it is more stable and cheaper.

Organization use Linux as Server operating systems, desktop and many more. For network systems we use to protect network by using it as firewall and proxy server, and we also use it for bandwidth management so we can manage users bandwidth while accessing internet.

Linux is also been use as email server and database server, it’s cheap and reliable. Many major company rely their business on Linux system as it fast and cheap. Organization gain more benefit while moving their system to linux. For office productivty there is open office application that can be used to boost users productivity so they can keep productive as while they are using other Operating system.
