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.

Buy Anti Virus – Protect Your Identity Online

June 27th, 2010

Identity theft is a fact of life these days. Every day, a whole lot of people have their identity stolen by hackers and criminals who then use the information to open credit card accounts and buy things in their name. A lot of these people are very careful about protecting their sensitive information except when they are online. The Internet makes it very easy to get banking done and purchase things fast. However, if you are not be careful on what you do on your computer, you may be leaving yourself open to a hack attack.

I do not know about you, but I get a few scam emails everyday asking me to provide my bank account number to a person in Nigeria and receive $1M in return. You should avoid falling for these scams. It is the easiest way to compromise your sensitive information.

Phishing attacks are all too common these days. You should never click on links you get in your e-mail from companies such as Chase and PayPal. Not that these companies want to steal your information. Rather, there are many criminals who send emails to people, claiming to be from these companies. As soon as you click on these links and log in, your information is compromised.

Another way you can have your identity stolen is by being negligent about viruses when you are online. Many online sites such as a few P2P sites put harmful software on your computer. A keylogger can steal your password and send it to a third-party system. You should take time to buy an anti-virus and firewall system to protect yourself against hack attacks. It would be even better if you can afford a cheap laptop to just use for online banking.

Finally, never store your passwords on your computer and make sure you do not submit your password to a non-secure website. It is not only reckless, but can leave you susceptible to online identity theft. Buy Anti Virus with personal firewall.

While no tactic is foolproof here, by following the above steps you can significantly lower the chances of your data being stolen by criminals. You should also invest in an ID tracking service to get alerts in case your information is compromised. One ca not be too careful these days.

Looking for an Identity monitoring service to protect your ID theft? Try buy anti virus software to protect you.

Why Buy Anti-Virus Software?

June 27th, 2010

So what is a virus?

A virus basically comprises a small program, a macro or a script designed to interfere with the normal functioning of a computer in various ways. At the grass root level these mischievous entities gain entry into our computers through external storage devices such as floppies, compact discs etc. However, with the advent of internet, viruses now have a much easier way to infiltrate our PCs. All that the warped mind of a virus programmer has to do now is write the necessary code and introduce it into the internet system via an e-mail or other web enabled procedure. The online network means the virus can infiltrate literally billions of PCs in a short period of time. Days, or perhaps weeks later, the virus gets identified and a battery of coders or software professionals get down to building the vaccine to quell the code. Another change to the virus landscape is that they are now largely used to profit financially by stealing valuable information whereas before maximum disruption was the aim.

Pleasure of proving someone wrong

Software companies often come out with inflated claims about the security of their latest creations which exaggerations of virus proof protection all to common. They claim that it is impregnable and that users will enjoy an uninterrupted experience when using the software. This is what generally kicks off the war. World over, there are people, mostly teenagers and those in their twenties who fancy breaking into the secure environment created by the big players in the software industry. They may not do this for any monetary gains, but to derive pleasure from being able to unsettle the claims made by the big names.

Best anti virus downloads – are free ones ok?

In order to combat viruses it has now become necessary for PCs users to protect themselves and not rely on their operating system and software to do it all. In response to this need there is naturally a large number of anti virus downloads available on the internet; some are good, some are bad and some will do you more harm than the original virus. You will also need to decide if you need to buy antivirus software or just get a free version. Like with most things, those that charge a fee are usually better although this is not always the case. However, it is worth noting that a major impediment with several free downloads is that many of them do not have an uninstall facility. This means that once you have chosen to install the free anti virus program and you will find it difficult to migrate to another version later. You will either have to leave both on your hard drive or reformat your hard disk. Another important factor is the lack of continuing support from the free providers, particularly regular updates. Viruses keep sprouting every second and if the provider does not update the software for the new viruses almost on daily basis, your computer security may be compromised. You should consider these two points carefully before deciding you want to save a bit of money and opt for the free versions.

overview of Anti-Virus Programs

October 21st, 2009
Rising AntiVirus
Image via Wikipedia

The continual penning and circulating of computer viruses and of panic about them grants the sellers of commercial anti-virus software a financial interest in the ongoing existence of viruses. A few suppose that anti-virus companies have fiscal links to virus authors, to generate their own marketplace, though there’s actually no evidence that we know of. Some of the anti-virus software can reduce computer performance considerably. Users can disable the anti-virus protection to get over the performance loss, therefore raising the danger of infection.

For the greatest protection the antivirus software requires to be enabled at all times-often at the cost of more sluggish performance. It’s also all important to recognise that an individual shouldn’t have more than one antivirus software package set up on an individual computer at any given time. This may severely cripple your computer and cause additional damage. It is essential to temporarily disable computer virus security while you set up major updates such as Windows Service Packs or updating graphics card drivers. Having antivirus protection functioning at the same time as installation of a major update might keep the update from installing correctly or even installing at all.

Once you do make up your mind to buy antivirus software, the arrangement might include a clause that your subscription will be automatically renewed, and your credit card automatically charged at the time you’re supposed to renew without you authorising it. For instance, Mcafee expects you to subscribe at least sixty days prior to the expiration of your present subscription, Whenever that’s the case, the subscriber could contest the charges with the credit card issuer, but this course of action is probably to be of no help to you if as a matter of fact the subscriber had cleared such a “uninterrupted payment authority”.

A few anti-virus programs are in reality malware masquerading as anti-virus software. It’s to your advantage to ascertain that the software package which you’re downloading is really a genuine antivirus program. A few commercial antivirus software programs hold adware, For instance, the home/small business edition of a CA Anti-Virus 2008 exhibits an advertisement for CA products whenever the desktop is unlocked after a period of time while the computing machine isn’t active. It will be no surprise when computer viruses that plague the desktop and the laptop computer world rapidly migrate to mobile devices. Increasingly sellers in this space are providing solutions to combat this.

Antivirus programs arrive in a lot of various forms and range from affordable to very costly but believe me, without an anti-virus program you’re going to finish up worse off money-wise in the end because of the expenses of reviving or replacing your computer. You are able to locate a lot of these types of programs for your home computing machine or office computer right here on the World Wide Web or in some computer shop in your region. Good luck with keeping your computer up and running correctly and if you don’t already have an antivirus program for your computing system, please look at opting to buy yourself one without delay.

KDE 4 Current version: 4.4 Older versions: 4.0...
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.

Should You Buy Anti-virus Software Or Get a Free Version?

October 12th, 2009

Which is more beneficial to you buy anti virus software or downloading the free version online? Computers have become so important in so many parts of our personal and professional life that it is very important to safeguard the data stored in them against viruses which are designed to destroy or steal it. Many people got this kind of attack everyday so it is important for you to protect your data.

However, many people take this very lightly and never think twice about the damage that can be caused by such viruses. So thinking that they are saving money they go for free online downloads of antivirus applications. What they do not realize is that even these free antivirus downloads might be spam or can inject virus into the system that may harm your computer network systems.

Those free versions that are not malicious in their intent may however be very ineffective in detecting and destroying viruses. Much antivirus freeware is outdated and not powerful enough to fight the virus or remove it fully from the system. Most of them can not help you to create a secure network.

Keeping this in mind many software companies are trying to cash in on the demand for a good antivirus software. So they introduce antivirus software which is powerful enough to fight any form of virus and it also provided one year free upgrade after which time the user can update the virus for a small additional fee. This software is normally moderately priced you can buy anti virus at ($25 – $65) and can provide a complete solution for your systems security and safeguard the data from virus threats.

When you become a paid customer of an antivirus program you are entitled to certain special benefits which you are devoid of when you download free antivirus software.  You will need to pay for customer support, possible after a short period of free support, but the most serious disadvantage is that the software is not automatically updated regularly. This prevents it being effective against new viruses which come on coming day after day.

Whereas when you buy anti virus software the software company is responsible for all your queries related to the software and it’s functioning. As the competition among the antivirus software companies increases more are offering increasing functionality (i.e. antiadware, privacy features etc) and better value. Free 24/7 live support is also becoming offered by some of the big players. Moreover the software that you buy will entitle you for a free upgrades for at least one year and after that you need to pay only a small fee to upgrade and continue using the software.

Therefore many benefits are experienced when a user buy anti virus software. Now, this may come as no surprise but it is all too common for people to pay more in the long term by taking the cheap short term option. Even if you already had a firewall you still need to buy anti virus to protects your network systems.

Anti virus PC

October 12th, 2009

Anti virus PC is something you need when you working with computer. There are some simple steps you must take to avoid becoming a victim of computer viruses and also stop from spreading viruses to others. Here are some things that you can and should do.

Email Issues to watch

Never open an E-mail with an attachment you were not expecting.

The latehttp://www.asidojaya.com/wp-admin/post.php?action=edit&post=88&message=1st batch of virus programs are often spread by E-mail. Even if your anti-virus program does not warn you about the attached file and even if the eMail appears to come from someone you know or from internal network systems, do not open it if you were not expecting it, and if you were expecting it, only open it AFTER scanning it with your up-to-date virus software. So please be wise here.

Scan ALL incoming email attachments (regardless of who sent it).

Be sure to run each attachment you plan to open through the anti-virus check. Do this even if you recognize and trust the sender; malicious code, like Trojan horses, can slip into your system by appearing to be from a friendly source.Turn off the ‘automatic preview’ in your email program.

Automatically previewing an email message has the exact same effect as opening and reading an email. My experience of the newest internet worms, trojans, and viruses simply need to have an email message read in order for them to be activated. Turning off the preview feature allows you to scan any email BEFORE you actually read it.Disk Issues to watch

Don’t boot from a floppy disk.

Floppies are one of the most common ways viruses are transmitted. If you are using a floppy while working on your computer, remove it when you shut the machine off or the computer will automatically try to boot from the floppy, perhaps launching any viruses on the disk. ANd also do not boot from flash disk or thumb drive.

Web Based Issues

Keep your web browser set to its highest security level.

Its a pain to get the warning messages on every other web page you visit, but its the best way to protect yourself – especially if you use Microsoft Internet Explorer and Outlook.

Don’t download programs from the Web.

Unreliable sources such as Internet newsgroups or Web sites that you haven’t heard of may be willing providers of viruses for your computer. This includes freeware, screensavers, games, and any other executable program – any files with an “.exe” or “.com” extension, such as “coolgame.exe.” Check to see if the site has anti-virus software running on their side. Avoid downloading files you can’t be sure are safe. If you do have to download from the Internet, be sure to scan each program before running it. Save all downloads to one folder, then run virus checks on everything in the folder before using it. Regardless of where you download from, ALWAYS scan downloaded software.

Routine Maintenance

Make regular back ups of important data you do it everytime you finish your work. You can store your backup using external drive. Make it a habit to back up all of your most important files at least once a month. Store the back up discs in a safe place. If your office has regular backup strategy using tape backup use it.

Clean any virus/worm/trojan off your computer

Using your antivirus software, perform a full system scan of your PC, hopefully it will detect and remove the virus. If a virus was detected, restart your computer and run the full scan again. Sometime the virus will keep reappearing, due to the evolving nature of viruses. Symantec is particularly fast at providing removal tools should you ever get a virus or worm infesting your computer.

What is a removal tool? Well simply put it is a simple software that will scan your computer for infections, and then remove them from your machine. You most often need this if your machine got infected BEFORE you installed antivirus software.Top Considerations for PC Protection

And the final and most important two things to do to keep your computer clean and make sure it does not spread viruses to other computers…

Install a Firewall

If you use a broadband/high-speed method to access the internet, you need to get a firewall. A firewall is a program that defends your computer from hackers who attempt to gain direct access to your computer over the Internet. There is a very good firewall program called ZoneAlarm that will do the trick if you use Windows.

Install and use a high-quality anti-virus program.

This is the key to protecting your computer. Buy one of the major anti-virus programs – Norton Anti-Virus, PC-Cillin, or McAfee Anti-Virus. The primary benefit of the commercial packages is the frequency and ease of updating the virus definition files that these programs use to detect viruses. With new viruses popping up all the time, unless your protection software is kept updated, you start to become ever more vulnerable to infection.

Get immediate protection.

Configure your anti-virus software to launch automatically on start-up and run at all times. This will provide you back-up protection in case you forget to scan an attachment, or decide not to. And in case you forget to load up your anti-virus software, configuring it to start by itself will ensure you get immediate protection anyway. The top antivirus software programs all do this (but only if you have one installed on your computer). You do have current antivirus software installed right?

Learn how to remove blackworm virus and how to easily block trojan horses, spyware, computer viruses, and other malicious software in the future.

Antivirus Reviews 2009 and Fast Computers

October 11th, 2009
I constructed this image using :image:Computer...
Image via Wikipedia

Many people looking about antivirus reviews as they are many products that compete each other to be the best. Since internet era spreading of a virus become faster and infected PC become much more day after day. So to help these kind a people we made some antivirus reviews so you can choose what best for you.

Well, the basic step for protecting your system is to install an anti-virus that works for your computer system. What do I mean by an antivirus that works for you? Well, everyone visits a different set of websites everyday, has a different system configuration, does different things with his/her PC and keeping all that in mind you need to decide which one works for you. This, I say from personal experience.

If you are yet not sure whether you even need an antivirus : Check this out (Scroll down)

The thing to note is that not every Antivirus is suitable for every system and hence you may need to experiment a bit before you find the perfect one.

I am not going to write paragraphs on this, just the ‘Good’ and the ‘Bad’. ASk if you have doubt.

Note: The software are listed in an alphabetical order and not preferential.

1. AVG Antivirus:

Good: Only antivirus thats free to use and ranks among the best. Eeffective, easy to use and compatible with almost every computer. Try it out ? Sure, its free !

Bad: No tech support to go to if it falters as its free. May skip some of the viruses. Keep a check.

2. Bit Defender:

Good : Has earned good reviews based on its superior performance and cost effectiveness. Pocket-friendly.

Bad : The interface is not that friendly and you may need to dig a lot deeper to find the in-depth reports of your scanned files (which lie in the Antivirus and Updates tabs).

3. Esset NOD32:

Good: An antivirus that is known for its quite simple and user friendly interface, NOD 32 is very simple to use and is usually recommended for beginners. The other advantages of the software include its high detection ratio, no software conflicts and the fact that it won’t drain your system. If you are looking for a fast antivirus, nothing beats the NOD32.

Bad: Slightly on the heavier side in terms of the price.
