My 14 Days With Ubuntu
By Rick Castellini

I can’t believe it has been two weeks already that I’ve used Ubuntu Linux exclusively. If I had to sum up the experience 100x100ubuntuin one word, that word would be “satisfying.” And my regular readers/listeners know that I can’t sum anything up in one word, so I will use this format to provide a complete synopsis of my Ubuntu thoughts.
Minimum Requirements

Ubuntu and its derivatives can run on extremely modest computers. Ubuntu works best on a system with at least a 500mhz processor and 192 mb of RAM…specs that even the six year old Windows XP would choke on and Vista needs triple those specifications to even get close to running at any appreciable speed. Xubuntu is a very basic operating system capable of doing all the major computer functions, but only requires a 166mhz processor and 48mb of RAM! That’s a computer that was sold in the early 90′s!!

These modest system requirements are what first drew me to Ubuntu. Compared with the monster hardware required to run Vista, Ubuntu gives new life to computers previously thought ready for the scrap pile. The fact that Ubuntu is FREE on top of all this is just a bonus.
Available Applications

A fresh install of Ubuntu (typically less than 30 minutes) gives any computer user the ability to:

* Browse the Internet

* Send and receive email

* Download digital photos from a camera

* Edit digital photos

* Create word processing documents

* Create spreadsheets

* Create slide presentations

* Play games like Sudoku, solitaire, blackjack, Mahjongg and more

All of the above are full version programs…not time limited or crippled versions and they are all free.
Who can use Ubuntu?

Literally anyone that can click a mouse or type on a keyboard can you use Ubuntu. The real question is; Who is right for Ubuntu? Here are my thoughts:

* Any aged computer user who only needs a computer for Internet, email, and occasional word processing. This is probably my idea of the number one demographic for Ubuntu.

* Any aged computer user who wants to do the activities I listed above plus download and do light editing of photos and play basic games.

* Families who want a solid, inexpensive, worry free computer system that the kids can do homework on and play Internet games on as well.

About the only group of people who I think should not use Ubuntu are those who require specialized industry software or software only available for Windows.
Ubuntu Support

Dell started selling Ubuntu desktops earlier this year and if you buy a computer with Ubuntu pre-installed at Dell or other vendors you might find, you will have the option for phone support. However, the power of Ubuntu is its community. The Ubuntu forums are second to none in being able to find answers to many existing questions and the ability to ask questions that come up as you use the system. I have found the forums to be extremely well organized and frequented by cordial, knowledgeable individuals. Also, many states offer Ubuntu users groups called LoCo groups for even more localized support.
Ubuntu Weaknesses

As much enthusiasm as I have for Ubuntu, I am not so blinded by love that I don’t see the chinks in the armor. And like ANY software or operating system, Ubuntu has a few chinks. The most glaring, in my opinion, are:

Hardware support. The Ubuntu community continues to work hard at providing drivers and programs that will work with every printer on the market and off the market as well as scanners, digital cameras (use a card reader for no problems at all), web cams and other devices. However, the number of hardware devices that have been available over the past ten years is staggering and Ubuntu has a lot of catching up to to do.

Wireless Internet. Once I figured out wireless on this laptop, I have had few problems, but getting wireless up and running requires some patience, technical know-how, and willingness to research the web for answers. It is getting better, but not as easy as wireless with Windows…yet.

Database. I love working with desktop databases. My skills are unfortunately pretty weak with databases, but I recognize their power and possibility so I constantly dabble in them. I was sorely disappointed with OpenOffice’s database program. It was slow, couldn’t handle much data and hard to customize. This all surprised me since their word processing, spreadsheet and presentation manager program all work so well.
Summary

At the beginning of this article I summarized my Ubuntu two week trek as being satisfying. I was satisfied that Ubuntu handled almost everything I threw at it. I was satisfied that I think the interface is such that any computer user of any age or ability could quickly get up to speed with Ubuntu. I was satisfied to have found a robust operating system that doesn’t break the bank in terms of computer needs and actual costs. As a tech guy who helps other fix their computers, I was extremely satisfied to use an operating system that requires virtually no worries about computer Internet security.

Will I continue to use Ubuntu? Absolutely, as my primary laptop? Will I give up my Windows PC? Not until all the support that I give lies only in Linux, which unfortunately won’t be any time soon.

Questions and Answers About the Linux Operating System

By Andrea Tessi

The purpose of this article is to give answers to some basic questions common people may have about Linux. Linux is a free operating system whose popularity is increasing day by day and passed from being the toy of a small geek group to a robust and mature piece of code so much as to start challenging Microsoft Windows leadership.

Q. What is exactly Linux?
A. Actually three different things yet belonging to the same environment are named Linux. Originally it was used to name the kernel of the Linux Operating System (whose complete name should be hence “GNU Linux”) and eventually it was used to simply refer to the Linux Operating System. Finally, a lot of application software was added both by spontaneous programming groups and by software companies, creating software collections also known as distributions. So nowadays the name Linux is used for three different things: the kernel, the operating system and the distribution.

Q. Who created Linux?
A. The author of the Linux kernel is basically Linus Torvalds, a finnish computer science expert who developed it as an experiment during his university career. Later, a team of volunteers helped him improving and enhancing it.

Q. Are Unix and Linux the same thing?
A. No, though Linux has been written from the Unix code. Anyway, it is so similar to the operating system family known as “Unix” to the point that experts use to refer to Linux as “Unix like”

Q. How much does it cost?
A. Linux is free and it comes with a licence known as “GNU GPL”, which grants free use, free access to the source code (Linux distributions often come with both binaries and the source code), freedom to copy, modify and distribute it.

Q. Are there many people using Linux?
A. Nowadays Linux is becoming very popular. There are many people that neither are geeks nor computer experts turning to Linux every day. During the last 5 years Linux evolved to become very user friendly, and for some tasks even more than Microsoft Windows.

Q. Can I run a Windows program on Linux?
A. Basically no. Linux and Windows are so different that a program written and compiled for Windows won’t run on Linux and vice versa. An exception may be done for Java programs, provided that the Java Virtual Machine is installed in the system. However, a few developer groups and software companies are committed in developing emulators that make possible, under certain circumstances, to run some Windows programs on Linux.

Q. Are there programs for linux similar to those running on windows?
A. Yes. For the most common tasks we can say that every Windows program has its free equivalent on Linux. In many cases Linux offers more than one alternative. The most famous are Firefox for internet surfing, Open Office for office automation (wordprocessing, spreadsheet, presentation, drawing, html pages, database and more), Evolution as an e-mail client, The Gimp for photo and image manipulation.

Q. Can I run Microsoft Office on linux?
A. No. Microsoft announced that they will never port (i.e. make it compatible) Microsoft Office to Linux. However, it is possible to run the original code (with some limitations, I guess) using a Windows emulator.

Q. Is Linux easy to learn?
A. Linux has become very user friendly nowadays. For a normal user the learning curve is not steeper then for learning Windows or MacOs.

These are some basic answers to questions people ask me when I tell them I use Linux. It still seems strange to most of them that somebody nowadays can use an operating system that neither is Windows nor MacOs.

Differences Between Linux And Windows
By Matt Gebhardt

This article will discuss the differences between the Linux and Windows operating software; we discuss some of the pro’s and con’s of each system.

tux-100x100Let us first start out with a general overview of the Linux operating system. Linux at its most basic form is a computer kernel. The Kernel is the underlying computer code, used to communicate with hardware, and other system software, it also runs all of the basic functions of the computer.

The Linux Kernel is an operating system, which runs on a wide variety of hardware and for a variety of purposes. Linux is capable of running on devices as simple as a wrist watch, or a cell phone, but it can also run on a home computer using, for example Intel, or AMD processors, and its even capable of running on high end servers using Sun Sparc CPU’s or IBM power PC processors. Some Linux distro’s can only run one processor, while others can run many at once.

Common uses for Linux include that of a home desktop computing system, or more commonly for a server application, such as use as a web server, or mail server. You can even use Linux as a dedicated firewall to help protect other machines that are on the same network.

imagesA programmer student named Linus Torvalds first made Linux as a variant of the Unix operating system in 1991. Linus Torvalds made Linux open source with the GNU (GPL) (General Public License), so other programmers could download the source code free of charge and alter it any way they see fit. Thousands of coders throughout the world began downloading and altering the source code of Linux, applying patches, and bug fixes, and other improvements, to make the OS better and better. Over the years Linux has gone from a simple text based clone of Unix, to a powerful operating software, with full-featured desktop environments, and unprecedented portability, and a variety of uses. Most of the original Unix code has also been gradually written out of Linux over the years.

As a result of Linux being open source software, there is no one version of Linux; instead there are many different versions or distributions of Linux, that are suited for a variety of different users and task. Some Distributions of Linux include Gentoo, and Slackware, which due to the lack of a complete graphical environment is best, suited for Linux experts, programmers, and other users that know their way around a command prompt. Distributions that lack a graphical environment are best suited for older computers lacking the processing power necessary to process graphics, or for computers performing processor intensive task, where it is desirable to have all of the system resources focused on the task at hand, rather than wasting resources by processing graphics. Other Linux distributions aim at making the computing experience as easy as possible. Distributions such as Ubuntu, or Linspire make Linux far easier to use, by offering full-featured graphical environments that help eliminate the need for a command prompt. Of course the downside of ease of use is less configurability, and wasted system resources on graphics processing. Other distributions such as Suse try to find a common ground between ease of use and configurability.

“Linux has two parts, they include the Kernel mentioned previously, and in most circumstances it will also include a graphical user interface, which runs atop the Kernel” reference #3. In most cases the user will communicate with the computer via the graphical user interface. (ref #6) Some of the more common graphical environments that can run on Linux include the following. The KDE GUI (Graphical user interface). Matthias Ettrich developed KDE in 1996. He wanted a GUI for the Unix desktop that would make all of the applications look and feel alike. He also wanted a desktop environment for Unix that would be easier to use than the ones available at the time. KDE is a free open source project, with millions of coders working on it throughout the world, but it also has some commercial support from companies such as Novell, Troltech, and Mandriva. KDE aims to make an easy to use desktop environment without sacrificing configurability. Windows users might note that KDE has a similar look to Windows. Another popular GUI is (ref #7) GNOME. GNOME puts a heavy emphasis on simplicity, and user ability. Much like KDE GNOME is open source and is free to download. One notable feature of GNOME is the fact that it supports many different languages; GNOME supports over 100 different languages. Gnome is license under the LGPL license (lesser general public license). The license allows applications written for GNOME to use a much wider set of licenses, including some commercial applications. The name GNOME stands for GNU Network object model environment. GNOME’s look and feel is similar to that of other desktop environments. Fluxbox is another example of a Linux GUI. With less of an emphasis on ease of use and eye candy, Fluxbox aims to be a very lightweight, and a more efficient user of system resources. The interface has only a taskbar and a menu bar, which is accessed by right clicking over the desktop. Fluxbox is most popular for use with older computers that have a limited abundance of system resources.

Although most Linux distributions offer a graphical environment, to simplify the user experience, they all also offer a way for more technically involved users to directly communicate with the Kernel via a shell or command line. The command line allows you to run the computer without a GUI, by executing commands from a text-based interface. An advantage of using the command prompt is it uses less system resources and enables your computer to focus more of its energy on the task at hand. Examples of commands include the cd command for changing your directory, or the halt command for shutting down your system, or the reboot command for restarting the computer ect.

Now that we are more familiar with the Linux operating system, we can note the many ways in which Linux differs from the worlds most popular OS, Microsoft Windows. From this point forward we will discuss some of the more prominent ways in which Linux deferrers from Windows.

Windows_7For starters there is only one company that releases a Windows operating system, and that company is Microsoft. All versions of Windows, weather Windows XP Home, Business, or Vista, all updates, security patches, and service patches for Windows comes from Microsoft. With Linux on the other hand there is not one company that releases it. Linux has millions of coders and companies throughout the world, volunteering their time to work on patches, updates, newer versions, and software applications. Although some companies, charge for TECH support, and others charge for their distribution of Linux, by packaging it with non-free software, you will always be able to get the Linux Kernel for free, and you can get full-featured Linux desktops with all the necessary applications for general use, for free as well. The vendors that charge money for their distribution of Linux are also required to release a free version in order to comply with the GPL License agreement. With Microsoft Windows on the other hand you have to pay Microsoft for the software, and you will also have to pay for most of the applications that you will use.

Windows and Linux also differ on TECH support issues. Windows is backed by the Microsoft Corporation, which means that if you have an issue with any of their products the company should resolve it. For example if Microsoft Windows is not working right, then you should be able to call Microsoft and make use of their TECH support to fix the issue. TECH support is usually included with the purchase of the product for a certain amount of time, maybe a two year period, and from there on you may be charged for the service. Although IBM backs their Linux products, for the most part if you use Linux you are on your own. If you have a problem with Ubuntu Linux you cannot call Ubuntu and expect any help. Despite the lack of professional help, you can however receive good TECH advice, from the thousands or millions of Linux forums that are on the web. You ca also get great help from social networking sites such as Myspace, by posting questions in the many Linux groups. You can usually receive responses for your questions in a matter of hours form many qualified people.

Configurability is another key difference between the two operating software’s. Although Windows offers its control panel to help users configure the computer to their liking, it does not match the configuring options that Linux provides especially if you are a real TECH savvy user. In Linux the Kernel is open source, so if you have the know how, you can modify it in virtually any way that you see fit. Also Linux offers a variety of Graphical environments to further suit your needs. As mentioned earlier Linux is capable of running full-featured graphical environments like KDE, or more lightweight and resource friendly GUI’s like Fluxbox, or Blackbox, to suit users with older computers. There are also versions of Linux that are designed to emulate the Windows look and feel as closely as possible. Distributions such as Linspire are best suited for users that are migrating over from the Windows world. There are also distributions that include no graphical environment at all to better suit users that need to squeeze out all of the computing power that they can get for various computing activities, and for users that are more advanced than others. All of this configurability can be problematic sometimes, as you will have to make a decision on which desktop is right for you, and to make things easier on yourself you will need to only install applications that are native to your distribution and graphical environment.

(ref #1) The cost effectiveness of Linux is another way it separates itself from Windows. For home use Linux is cheap and in most cases completely free, while Windows varies in cost depending on which version you buy. With Linux most of the applications will also be free, however for Windows in the majority of cases you are suppose to pay for the applications. For most cases, with Linux there is no need to enter a product activation key when performing an installation, you are free to install it on as many computers as you’d like. With Windows you are only allowed to install it on one computer and Microsoft uses product activation software to enforce this rule. When installing Window’s you must enter a product activation key, which will expire after so many uses. If you wish too, you can purchase Linux from a variety of vendors, which will include a boxed set of CDs, Manuals, and TECH support for around 40-130$. Of course If you purchase a high-end version of Linux used for servers it may cost any where from 400$- 2000$. “In 2002 computer world magazine quoted the chief technology architect at Merrill Lynch in New York, as saying “the cost of running Linux is typically a tenth of the cost of running Unix or Windows alternatively.” (ref#1)

(ref #1) Installation of Windows is generally easier, than installing Linux. “With Windows XP there are three main ways to install. There is a clean install, in which you install Windows on a blank hard drive. There is also an upgrade install, in which you start with an older version of Windows and “upgrade” to a newer one. An advantage of upgrading is that all of the files on the older system should remain intact throughout the process. You can also perform a repair install, in which case you are installing the same version of Windows on top of itself in order to fix a damaged version of Windows. There is also a recovery, which Technically is not an install; it is used to restore a copy of Windows back to its factory settings. The disadvantage of recovering Windows is the fact that you will loose all of your data, which resides on the damaged copy of Windows.” (ref#1) Also with Windows you can rest assured that your hardware will most likely be supported by the operating software, although this is not much of a problem with Linux you cant be sure if Linux will support all of your hardware. With Linux installation varies greatly from Distro to Distro. You may be presented with a graphical installer or it may be a text-based installer, these variations make Linux a bit more difficult and unpredictable to install than is Windows, (although the difficulty is disappearing). You may perform a clean install of Linux or dual boot it, to co-exist with another operation software. With Linux rather than having to buy an upgrade Cd, you can install updates by downloading and then installing them while your desktop is running. With Linux it is also not necessary to reboot your computer after most upgrades, It is only necessary to reboot after an upgrade to the kernel. It is also possible to run Linux without ever needing to install it on a hard drive; there are many distributions of Linux that will allow you to run it straight off of a live cd. The advantage of this is that you do not need to alter your system in order to try Linux. You can run Linux off of the CD so you do not have to damage your Windows partition. Other advantages include the ability to rescue a broken Linux system. If your Linux computer will not boot, then you may insert a live cd and boot off it, so you can repair the damaged version of Linux. Also you may use a Linux live cd to recover files from a damaged Windows computer that will no longer boot up. Since Linux is capable of reading NTFS files you may copy files form a Windows computer to a USB flash drive or floppy drive etc.

Another major difference between Linux and Windows is the applications that you will use with either OS. Windows includes a much wider abundance of commercially backed applications than does Linux. It is much easier to find the software that you are looking for with Windows than it is with Linux, because so many software vendors make their products compatible with Windows only. With Linux you will for the most part be forced to let go of the familiar applications that you have grown accustomed to with Windows, in favor of lesser-known open source apps that are made for Linux. Applications such as Microsoft office, Outlook, Internet Explorer, Adobe Creative suite, and chat clients such as MSN messenger, do not work natively with Linux. Although with Linux you can get Microsoft office and Adobe creative suite to work using software from codeWeavers called cross Over Office. Instead of using these applications you will need to use Linux apps such as open office, The Gimp Image Editor, The ThunderBird email client, Instead of the MSN messenger you can use the GAIM messenger, and you can use Firefox as your web browser. Also with Linux it can be difficult to install software even if it is made for Linux. This is due to the fact that Linux has so many different versions. Software that is made to install on one version probably will require some configuration in order to install on another version. An example would be if you were trying to install software that was made for the KDE graphical environment, on the GNOME GUI, This app would not easily install on the GNOME GUI, and would require some configuring on your part to successfully install it.

The type of hard ware that Linux and windows runs on also causes them to differ. Linux will run on many different hardware platforms, from Intel and AMD chips, to computers running IBM power Pc processors. Linux will run on the slowest 386 machines to the biggest mainframes on the planet, newer versions of Windows will not run on the same amount of hardware as Linux. Linux can even be configured to run on apples, Ipod’s, or smart phones. A disadvantage of Linux is when it comes to using hardware devices such as Printers, Scanners, or Digital camera’s. Where as the driver software for these devices will often be easily available for Windows, with Linux you are for the most part left on your own to find drivers for these devices. Most Linux users will find comfort in the fact that drivers for the latest hardware are constantly being written by coders throughout the world and are usually very quickly made available.

(ref #1) One of the most notable differences between the two operating software’s is Windows legendary problems with malicious code, known as Viruses and Spy ware. Viruses, Spy-ware and a general lack of security are the biggest problems facing the Windows community. Under Windows Viruses and Spy-ware have the ability to execute themselves with little or no input from the user. This makes guarding against them a constant concern for any Windows user. Windows users are forced to employ third party anti virus software to help limit the possibility of the computer being rendered useless by malicious code. Anti virus software often has the negative side effect of hogging system resources, thus slowing down your entire computer, also most anti virus software requires that you pay a subscription service, and that you constantly download updates in order to stay ahead of the intruders. With Linux on the other hand problems with viruses are practically non-existent, and in reality you do not even need virus protection for your Linux machine. One reason why Viruses and Spy-ware are not a problem for Linux is simply due to the fact that there are far fewer being made for Linux. A more important reason is that running a virus on a Linux machine is more difficult and requires a lot more input from the user. With Windows you may accidentally run and execute a virus, by opening an email attachment, or by double clicking on a file that contains malicious code. However with Linux a virus would need to run in the terminal, which requires the user to give the file execute permissions, and then open it in the terminal. And in order to cause any real damage to the system the user would have to log in as root, by typing a user name and password before running the virus. Foe example to run a virus that is embedded in an email attachment the user would have to, open the attachment, then save it, then right click the file and chose properties form the menu, in properties they can give it execute permissions, they would then be able to open the file in the terminal to run the virus. And even then the user would only be able to damage his or her home folder, all other users data will be left untouched, and all root system files would also remain untouched, because Linux would require a root password to make changes to these files. The only way the user can damage the whole computer would be if he or she logged in as root user by providing the root user name and password to the terminal before running the virus. Unlike Windows in Linux an executable file cannot run automatically, It needs to be given execute permissions manually this significantly improves security. In Linux the only realistic reason you would need virus protection is if you share files with Windows users, and that is to protect them not you, so you are not to accidentally pass a virus to the Windows computer that you are sharing files with.

The above was a general over view of some differences between the Windows operating system, and Linux. To recap we started with the fact that Windows has only one vendor that releases the software, while Linux comes from millions of different coders throughout the world. We also commented on the fact that the Linux Kernel and much of the applications used with it are completely free of charge, where as with windows you are forced to pay for most of the software. Unlike Widows Linux is often lacking in professional Tech support, and Linux users are often left on their own to solve Technical issues. Linux users can either pay for Tech support or rely on the many Linux Forums and groups available on the Internet. Due to the fact that the kernel is open source, Linux has a huge advantage over Windows in configurability. You can configure Linux to run almost any way you see fit by manipulating the Kernel. Installing the Windows Operating software and applications is easier due to the fact that it has a universal installer. Also finding applications for Windows is easier because of its popularity most apps are available for Windows only, and are made easily available. Linux will run on a greater variety of hard ware than does Windows, from mainframe super computers running multiple IBM Power PC Chips, to a small laptop running an AMD processor. And of course the biggest difference in this writer’s opinion is the fact that Linux does not suffer from an onslaught of Viruses and other malicious code, unlike Windows which is plagued by countless number of malicious code that can easily destroy your system if not properly guarded against.

In conclusion we will conclude that the Linux OS really is the superior software. Other than a few minor nuisances, linux out performs Windows in most categories. The fact that Linux is more secure is the tipping point, that tilts the scales in the favor of Linux. Windows simply suffers from far to many security vulnerabilities for it to be considered the better over all desktop environment.

Linux Text Processing
By Levi Reiss

DSL-logoDamn Small Linux can be an excellent tool for learning Linux commands and running the Linux operating system. But what if you are not interested in becoming a computer nerd; can this software still be useful to regular people? The answer is a resounding yes; you can make use of this tiny operating system whether or not you want to learn the sometimes gruesome details of operating systems. This article introduces the text editors that come with your free Damn Small Linux that runs on even obsolete Windows computers. You can use these applications to compose simple text or programs of any level of complexity.

Once you have downloaded and installed Damn Small Linux there are several equivalent ways of launching its text editors. You can click on the DSL button in the lower-left hand corner or on the Apps/ icon toward the top of the screen. Then open the Editors: there are four, Beaver, Nano, Notepad, and vi (actually vim). We will look at these editors in order plus an additional one.

beaver_pref_window

Beaver is my choice for creating and editing the text files used in my Damn Small Linux tutorials. The name Beaver stands for Beaver is an Early AdVanced EditoR which is the kind of joke that many Linux and Unix people find funny. This editor is particularly useful for programming and web page editing. Among Beaver’s special features are color coding and the ability to convert text to Upper Case, Lower Case or to capitalize the first letter of every word. You can convert text among the following formats: Unix, DOS, and Mac. Programmers will be happy to learn that Beaver formats code for the following programming languages: C/C++, HTML, Perl, JavaScript, PHP, and Bash. Unfortunately the Help function is not available. To learn more about this editor access their website at nongnu.org/beaver.

The nano program is especially used for email messages. It stems from the widely-used Pico email program that is not available for some versions of Linux. I have not had the pleasure of working with nano but am told that many Linux and Unix people like it.

What the Damn Small Linux people call Notepad is actually another text processor that is similar to the DOS/Windows Notepad. I haven’t used it because Beaver is more powerful, and just about as easy to use.

The final application in this group is VIM, vi IMproved. The original vi was a very-widely used text editor for Unix and Linux systems. Today most Unix and Linux people work with other, more sophisticated text editors. When I teach Linux on systems other than Damn Small Linux I teach a reduced version of vi. This editor is cumbersome, but you make like the improved version. Damn Small Linux offers you a choice.

The Office folder contains Ted, a word processor that is compatible with Microsoft Word. Ted saves documents in RTF (rich text format) that can be read by Microsoft Word and other word processors including Open Office. Ted and Beaver belong to different worlds; you can’t take documents back and forth between these two applications.

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.”

Yellow Dog Linux on PS3

Yellow Dog Linux on PS3
By Scott Ace

Did you know that your very own PS3 is actually more powerful then even the best home computers out on the market today. And more then likely it is two times as powerful as the computer you’re reading this from. We hear so much 128px-Ydllogo_3dabout home PC’s now having Dual Core technology but the PS3 comes with eight powerful CPU cores that absolutely blow anything out on the market today out of the water. So how can we harness this power and turn our humble PS3 into our very own super computer?

Well luckily for us Sony are way ahead of the pack. They built the PS3 with Linux distro’s in mind. And you can actually install Linux on your PS3 much the same way you would with your home computer. And there is nothing extra needed, no extra gadgets or software to buy, just plug and play essentially. Well… As plug and play as it gets with Linux anyway. The great thing is, is that you do not have to lose what you already have on your PS3. So games, music, anything installed on your hard drive is preserved. The PS3 just turns to dual boot mode much the same as a windows PC. So you can either select to go with your standard PS3 OS to play games, or switch to Linux to use it as a home computer.

Now with so many Linux distributions out there, it’s probably going to be a bit of a hard job to choose the right one right? Well actually, your options are slightly cut down due to the PS3 having too much power. (Yes that’s right, too many cores cause issues!). Most standard Linux distributions like redhat, ubuntu, gnome or kubuntu cannot handle the PS3′s 8 cores natively. Mostly down to home computers never having anything close to 8 processors.

This is where Yellow Dog Linux on PS3 comes to the rescue. Sony, know that people would want to utilize the power of 320px-Yellow_Dog_Linuxtheir PS3 into something more then playing First Person Shooters each and every day, commissioned a stripped down Linux distro to be directly developed for the PS3. This means your not just getting a “ported” Linux distro, your actually getting something that was made for the PS3 from day one. Not only does Yellow Dog Linux tick all the boxes for harnessing the power of the PS3, it comes prepackaged with everything that you could possibly ever use on your home computer. These extra include Open Office, Pidgin, Gimp and even Mozilla Firefox.

Installing Yellow Dog Linux On PS3 is actually incredibly easy do don’t be afraid that you are going to “Brick” your console by doing something you shouldn’t. Unlike the PSP, PS3′s were made for this sort of customization. And once again i have to point out, Yellow Dog was directly commissioned for this job so you wont be voiding your warranty by installing Yellow Dog Linux on your PS3.

Linux Training – Installing Linux on a Windows System
By Clyde E. Boom

The best way to get Linux training and Linux administration experience is to start by getting, installing and running Linux on a system. This allows you to actually work with Linux to run programs and learn Linux commands.

If you don’t want to buy a computer just for the purpose of running Linux, you can install Linux on your Windows system. You do this to create what is called a “dual boot” (Linux and Windows) system.

After you install Linux and boot your system, a menu appears allowing you to boot into Windows or boot into Linux!

7 Steps to Install Linux on Windows and Create a Dual Boot System

1. Back up your Windows programs and data

If you make a mistake when you install Linux on Windows you can loose all your Windows programs and data! Also, if you install Linux and then remove it later, you may not be able to boot into Windows.

Some people have run dual boot Linux systems without losing programs and data, but it’s good to know this downside. It’s extra incentive to do a backup.

Doing a backup is like buying insurance. If you don’t need it, fine. But if you do, you’ll be very glad you took this extra step.

2. Get Linux on CD or DVD

Select a Linux distribution (a.k.a. distro) and either download it and burn it to disk or buy it and have it delivered.

Linux Tip: To get Linux delivered, just do an Internet search for “linux cd” and you can have it mailed to you anywhere in the world for a very small fee.

3. Create empty unpartitioned disk space for Linux

Make sure your system has enough empty unpartitioned disk space for Linux. This isn’t just free disk space, as seen from within Windows. This is empty disk space that isn’t seen from within Windows.

4. Document your Linux installation settings

During the Linux installation, you need to specify some system settings. These include the Linux software programs and desktop(s) you want installed, networking settings, and disk partition sizes.

5. Start the Linux installation routine

To start installing Linux, you need to shut down your system and boot it with Linux CD / DVD number 1.

Some systems are set up to automatically boot from a CD / DVD if there’s one in the drive, and some need to have a system setting made. On other systems, you may simply need to hold down a key, like the letter “c” to boot Linux from CD / DVD.

6. Follow the prompts to specify settings and create a user

Linux systems have users and these users have names. You log in with a user name and password to work on a Linux system.

You work as the user named “root” to do Linux system administration. The root user is always created automatically during the installation. However, for security reasons, you should never log in to a Linux desktop as the root user.

As the installation routine runs, you will be asked if you want to create users. Always create at least one “regular” (non- root) user and give this user a password.

7. Have fun!

The Linux operating system is an incredible phenomenon. By getting it, installing it, and running it, you can get tons of experience working with it. Get a mitt and get in the game!

How to Configure SAMBA on a Linux Server
By Chris Ondo

Step By step guide to configuring SAMBA on a LINUX server.

This is for network administrators with experience configuring and administrating LINUX servers that want to know how to configure a SAMBA file server the right way step by step.

samba-logoIn this step by step tutorial I am going to show you how to make a shared folder on a linux server and share it so users on Microsoft windows workstations can access it on a local – internal network.

In this tutorial I am going to make the folder called “shared folder” and allow everybody access to the folder and printer networked to the Linux server.

This is a basic how to guide for configuring a samba workgroup file server.
I will cover how to build and configure a samba PDC – Primary domain controller in another tutorial for more experienced network administrators.

STEP 1
Open the samba configuration file using a unix text editor.
I like NANO since it is very easy to use.
Below are the commands I used to perform this task.

[root@localhost ~]# cd /etc
[root@localhost etc]# cd samba
[root@localhost samba]# nano smb.conf

Ok now we are in the smb.conf file
Now delete all the text in the configuration file.
Now copy and paste the below text…after that is done hit the “control and X buttons on your keyboard to exit out of the NANO text editor.
Then hit the Y button and last hit the ENTER button.
Now we are back to the command prompt and our samba configuration file is edited and saved.

[global]
workgroup = workgroup
server string = My Linux File Server
hosts allow = 192.168. 127.
log file = /var/log/samba/%m.log
security = user
netbios name = SAMBA SERVER
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

[shared folder]
comment = My Home Directory
browseable = yes
writable = yes
public = yes
read only = no

[printers]
path = /var/spool/samba
public = yes
guest ok = yes
printable = yes
browseable = yes
writable = yes
read only = no

STEP 2
We have to create a user acct on the Linux server itself then we will create a samba user on top of the Linux user acct.

[root@localhost ~]# useradd chris
[root@localhost ~]# passwd chris
Changing password for user chris.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@localhost ~]# smbpasswd -a chris
New SMB password:
Retype new SMB password:
getsmbfilepwent: malformed password entry (no :)
mod_smbfilepwd_entry: malformed password entry (no :)
[root@localhost ~]#

STEP 3
We have to start the SAMBA service.
It may already be started or it may not…so let’s check and see.

[root@localhost ~]# service smb status
smbd is stopped
nmbd is stopped
[root@localhost ~]#

The samba service is not running so let’s start it up

[root@localhost ~]# service smb start
smbd (pid 4267 4266) is running…
nmbd (pid 4271) is running…
[root@localhost ~]#

Now let’s verify the service is running

[root@localhost ~]# service smb status
smbd (pid 4267 4266) is running…
nmbd (pid 4271) is running…
[root@localhost ~]#

STEP 4
reboot your windows XP workstations then go to network “my network places” then go to “workgroup computers”.
You will see a computer there called “My Linux File Server”.
You can manually map a local drive letter to this folder or write a logon script the same as you would connecting to a Microsoft file server – shared folder.
Double click on that computer and you will be prompted for a user name and password.
Use the user name and password you choose in step #2
Now you will see a folder called “shared folder” You can copy and paste data to this folder just like it were a windows file server.

Kismet is a network detector, packet sniffer, and intrusion detection system for 802.11 wireless LANs. Kismet will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b and 802.11g traffic. The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. The client can also run on Microsoft Windows, although, aside from external drones, there’s only one supported wireless hardware available as packet source.

Kismet-2.7.1-screenshot

Kismet-2.7.1 Screenshot

Distributed under the GNU General Public License, Kismet is free software.

Kismet is unlike most other wireless network detectors in that it works passively. This means that without sending any loggable packets, it is able to detect the presence of both wireless access points and wireless clients, and associate them with each other.

Kismet also includes basic wireless IDS features such as detecting active wireless sniffing programs including NetStumbler, as well as a number of wireless network attacks.

Kismet has the ability to log all sniffed packets and save them in a tcpdump/Wireshark or Airsnort compatible fileformat.

To find as many networks as possible, kismet supports channelhopping. This means that it constantly changes from channel to channel non-sequentially, in a user-defined sequence with a default value that leaves big holes between channels (for example 1-6-11-2-7-12-3-8-13-4-9-14-5-10). The advantage with this method is that it will capture more packets because adjacent channels overlap.

Kismet also supports logging of the geographical coordinates of the network if the input from a GPS receiver is additionally available.

Kismet has three separate parts. A drone can be used to collect packets, and then pass them on to a server for interpretation. A server can either be used in conjunction with a drone, or on its own, interpreting packet data, and extrapolating wireless information, and organizing it. The client communicates with the server and displays the information the server collects.

Linux Commands Training Quick Tips – Using Linux Less & More Commands to Pause Output
By Clyde E. Boom

The more and less commands can be used with the | (vertical bar or “pipe” symbol) to pause the output of a Linux command.

Example of Using the Linux more Command

The more command can pause the output of a command, but it doesn’t work as well..

For example, you can’t scroll up in the output of a Linux command with the more command – or search for text in the output of a command.

Run the following command to list the contents of the etc directory, which is off of the / (root) directory – and to see the output “scroll off the top of the screen”.

$<b> ls -l /etc</b>

Now run the following command example to pause the output of the ls command so that it doesn’t “scroll off the top of the screen”.

Be sure to type in the | (vertical bar) between /etc and more.

$<b> ls -l /etc |</b> <b> more</b>

Linux Commands Training Tips:

The vertical bar “|” symbol is usually below the Backspace key on your keyboard and is referred to as the “pipe” symbol. It is used to “pipe” the output of one command into another command. In this case, you are “piping” the output of the less command to the more command.

Press the Spacebar a few times to scroll down a “screenful”.

Press the up arrow key and then the Page Up key and see that you can’t scroll up.

Press q to quit out of the Linux more command.

Example of Using the Linux less Command

Now run the less command example below to pause the output of the ls command.

Make sure you type in the | (vertical bar) between /etc and less.

$<b> ls -l /etc | less</b>

This shows the first “page” or “screenful” of the file.

Press the Spacebar to see the next “screen” of output.

Now press the down arrow key a few times, then the up arrow, then press the Page Down key and the Page Up key.

Press the End key to go to the end of the output and then Home to go to the top of the output.
