Ext3 (or extended file system) is used as the default file system for many of the Linux distributions. Since it is a journaled file system, it removes the need of running file system check after you encounter unexpected system shutdown. It also supports online file system growth and HTree indexing for large-sized directories. But irrespective of different security features it involves, the file system is prone to corruption. Its metadata structures might get corrupted due to several external and internal reasons. To solve such inconsistencies, Linux runs a boot-time fsck to detect and repair file system errors, if any. However, if it cannot resolve specific file system issues, you will need to run fsck manually or else use Linux Data Recovery applications to extract the lost data. As an instance, when you try to boot-up a Linux-based system with hard disk formatted to Ext3 file system, you might receive the similar error message: �??fsck.ext3 Unable to resolve ‘LABEL=boot�?� You encounter such errors after all hardware have been initialized and boot-time fsck is launched. Cause The above error is likely to occur in any of the following conditions: Wrong entry of boot partition in /etc/fstab file Boot partition is corrupted Hard disk contains bad sectors Solution You should apply these methods to troubleshoot such problems: Make sure that you have marked the correct entry of boot partition. To do so, you can boot into the system through installation disk and access the Rescue Mode. If boot partition corruption is the issue, boot the system using Linux installation disk and run fsck on /boot partition in Rescue Mode. Make sure that it is not mounted. Replace the hard disk if bad sectors are physical or first reformat it as bad sector might be logical too. After reformatting, restore data from backup. If fsck is unable to fix file system corruption and data is still inaccessible or you don�??t have valid data backup after reformatting the disk, it is recommended to use Linux Recovery tools for data recovery purposes. Such Linux Data Recovery applications are competent to scan a logically crashed drive and restore original data safely. Stellar Phoenix Linux Data Recovery is a comprehensive data recovery tool for Linux-based system that provides safe Linux Recovery for Ext2, Ext3, and ReiserFS file systems. The application empowers you with advanced features such as, Ext3 Recovery, File Filter, Append File Header etc. It is compatible with almost all Linux distributions including Gentoo, SlackWare, Mandrake, Ubuntu, SUSE etc.

In Linux operating system, you should arrange to mount root file system as read-only to start with at boot time. If required then remount the file system in read/write mode. Most of the Linux distributions follow this process. If your operating system does not do this, you must read the documentation and then find out how to set your file system to follow this process.

You are required to specify -n option to mount the file system so that it does not try to update the /etc/mtab directory, otherwise the file system will fail and you will not be able to access data from it. It might cause data loss in some situations and require Linux Data Recovery to be sorted out. When a file system failure occurs on Linux file system, you generally encounters following error messages, which may stop the functionality of your system:

In order to sort out the file system corruption problem, you are required to format the hard drive and reinstall operating system. This process will replace your damaged file system with new one and make your system working. But this process has a downside that it removes all of the data from hard drive and cause complete data loss that requires Data Recovery Linux for retrieving data. Recovery is possible through third-party applications, known as Linux Recovery software. The tools thoroughly scan the affected hard drive retrieve all of the lost data from it. They are completely safe and easy to use.

Stellar Phoenix Linux Data Recovery is the best ever made and the most advanced application that handles all types of data loss situations. It is compatible with most major distributions of Linux including Debian, RedHat, SUSE and Fedora. The software supports recovery from Ext4, Ext3, Ext2 and ReiserFS file system volumes.

Apple has once again demonstrated its precedence for creativity and innovation by launching next generation mobile Phone, the IPhone. Mobile phones once considered luxury have become an integral part of our daily life. Smart phones like Black Berry, IPhone, and Android intend to take mobile phone to next level by positioning them barely as communication device but as portable computing devices. No wonder the change is coupled with advancements and adaption of wireless internet technology. However, the impact of this innovation has transformed our daily lifestyle. No longer we use mobile phones for only staying connected, but we also use it for more trivial tasks including searching web, regularly checking emails, internet messaging, and conducting business transformation. This now allows people to be more connected to their work-life, businesses and the “world”.
The shift to portable computing device has provided an opportunity for enhancing productivity and reliability of businesses. For widespread usage, Apple recently launched App Store, building a marketplace for IPhone native application. As of today, numerous applications are available over Apple store in various categories including business, productivity, sports, games, etc. Though, numerous smart phones existed before: however IPhone touch concept and creative browser simply enhanced the experience resulting in mass adaption to concept.
IPhone applications are not only useful for enhancing personal productivity, but also have widespread usage in business automation application. Let me share few applications that can help enhance sales force automation. We understand various giants like Siebel, http://SalesForce.com, Sugar CRM are providing sales force automation solution etc. Still, IPhone based CRM solution are gaining mass appeal for its ability to further assist sales force in recording sales activity sheet at spot. Instant recording assists in increasing accuracy of reporting, and provide more updated sales view to management. Not only, this will provide quick information for sales managers, but also help sales managers do complex sales territory analysis utilizing GPS based feature. The GPS based sales automation system will not only help in making optimized sales territory allocation, but also more acceptable incentive based pay system. Long story cut short, IPhone present a huge opportunity for entrepreneurs. The opportunities exist for enhancing personal productivity by building applications for track shipments, manage personal finance, manage shopping list, arrange to-do, take personal notes and interact with friends near by.
IPhone applications can be served using standard web-interface or native application. Native application provides more control allowing features including offline access, GPS feature, Accelerometer and access to SQL-lite. Native application can be downloaded from Apple Store. Apple store hosts free as well as paid applications. To evaluate consumer preferences it would be helpful to review few top rated applications. iBowl is most famous IPhone application at apple store, available free of cost to download. The application simulates the bowling experience using accelerometer technology. User can swing the IPhone as a ball, and click on throw button, pushing the ball with the force of the swing. Though the application only measures force and does not take angle into consideration, but still its most highly rated application. The application is not only famous amongst youngsters but also amongst adults. No wonder, the application has just opened a whole new set of opportunities for innovative games, measuring hand gestures.
As opposed to native applications, browser based applications are usual HTML pages optimized for small screens. A large number of web pages are optimized for IPhone. Recently many social networking applications have been optimized for IPhone, including facebook. Facebook application is available both as native as well as HTML version. IPhone , web based interface, is optimized for small screen device like IPhone. The application heavily use custom animations i.e. page moving flying from right to left. The safari browser within IPhone does provide very good Ajax support and custom components.
Despite the global economic recession significant investments are made to transforming applications to Smart phones mainly IPhone. A definite analogy can be made to early transformation of desktop based applications to Web in late 90′s. Analyst feels that, similar to past trend, in late 2000′ all web applications are transformed for Mobile. The transformation has great opportunity for budding entrepreneurs as simple IPhone application can be developed for only 10K US $, with a significant expected return on investment.
Apparently simple looking IPhone applications require sophisticated process to ensure maximum success. In a highly competitive growing market, the success of any application heavily relies on idea. We suggest that due efforts should be put in evaluating idea by doing quick environment scan, competitive analysis and understanding customer needs. Once satisfied, the next step is to build requirement specification / user interface design. You must hire a user experience developer, familiar with IPhone development guidelines, to build design. The user interface will assist investors, innovators, and potential customers visualize product and provide early feedback. Then you should hire IPhone Application developer, who can build IPhone application faster, better and obviously cheaper for you. There are many companies which specialize in building IPhone applications. Please ensure to find register for Apple developer license for 99 US $, as it shall ensure in tracking payments and ensuring intellectual copyrights.

Choosing the appropriate operating system is based on the server`s function. Linux is powerful and has a versatile operating system while Windows is well-known for its easy to use operating system and versatility. Deciding the right server was certainly a trial as a decade ago, Microsoft`s Windows NT and Novell`s NetWare4 were prominently in use, but today NetWare has totally disappeared and the Linux version is found to be a good choice. Both Windows and Linux come in server and desktop editions.Maintenance and security are one of the significant areas to comprehend the actual differences between the operating systems. Linux are commonly referred to as distributions, also known as `distros`, and are released around the same time frame using the same kernel version (operating system). Linux needs careful consideration of hardware drivers as the hardware newly released should be appropriate and this includes the motherboard as well. Linux installation should be done by people who have proper knowledge to run the operating system and its applications. Linux is stable and more secure than Windows.On the other hand, Windows offers easy installation and runs even in default modes, besides it includes a series of drivers regardless of the hardware type and has the extensive variety of software. However it suffers with frequent security problems demanding critical patches involving rebooting. Moreover it is expensive right from the purchase price to the applications, besides ongoing maintenance is a must to keep it updated and stable.The comparison of Linux vs. Window includes other considerations such as the price, specialized options and support. Linux has server oriented versions available with vendors and some are offered with 24/7 paid support. There are less expensive distribution versions obtainable at Mepis, Centos and Xandros and others, which are offered at a very low cost to get started, while Debian, Slackware, Mint, Mandriva, Fedora of Red Hat and Ubuntu are all free versions.On the other side Microsoft Windows server is regular with 32 and 64 bit versions with specialized options such that it is ideal for small as well as medium sized businesses. However, the biggest hit is that Windows is buoyed up by a multi billion dollar company and is compatible with the majority of software, besides it is very easy in using and understanding that even an average user can make the best of it. Windows pricing varies dramatically based on the numbers purchased and on the yearly maintenance agreement or the licensing plan.The significant difference in Linux version does not speak about the software quality or the drivers` availability, but the support offered. Depending upon the Linux distribution package, the user may get a quick and 24/7 paid support, and this should well suit any corporate environment. Purchasing the operating system and hardware together ensures the support for installed hardware, else it may be required researching to ensure the motherboard, network adapter, chipset and others are supported by the Linux version. The other non-Linux options include OpenSolaris and many variants of Berkley Software distribution.

Many new Linux users are confused by the terms bantered around “Free”, Freely Available, Commercial Distributions and Shareware. The confusion comes primarily from the description and terms “Freely Available” and “Free” and their distinctions. Linux is open source software which means any software developer can add on to change the product�s basic source code. This is diametrically opposed to a strict proprietary concept such as Microsoft�s approach which is to own and have control the software and its code lock stock and barrel. There are some advantages to the proprietary approach particularly if you are dealing with a major mainstream product with millions and millions of users many of who are foolish novices; Life has enough problems without throwing in a monkey wrench to complicate efforts. Remember that if only 1/10 of 1 % of users think that if the computer throws out an error message commonly “You have committed an illegal actions” and run to lock their doors as the police are coming then that small percentage is a lot of people. The confusion arises in that the source code and any changes made to it must be made “freely available”… Whiskey may be “freely available” at your local saloon but that does not make it free of cost to you as a customer. However in actuality much of the software available in the Linux world is given away at no charge or cost except with the proviso that changes and work done to source code must be made available to others without restriction. Linux applications differ widely in cost and appearance. Many new Linux users are confused by the apparently contradictory terms used in Linux software product descriptions. These are “Freely Available Software,” “Shareware” and “Commercial Linux Applications.” Freely available software is available for free use by the end user. Although software may be freely available, it is often not the same thing as “Public Domain”software. Public Domain Software is software that is freely given on the open market either by the permission of the software developer or by being older than copyright constraints, that you as a user can do anything you wish to in terms of use, redistribution or changes. However”Freely Available Software”is different in that it is often owned and copywriter by the owner, author (or authors) who then allow people to use and/or make modifications to it. The term “Freely Available Software” can be further divided into software that you can either “Freely Copy” or “Freely Distribute.” Some people make their software “Freely Available” only if you copy or download it from a particular site or from a non commercial distribution. Other people will let you copy their software from anywhere. Copying restrictions usually apply to people making a commercial distribution, not to the end user of the distribution. The distribution maker has the responsibility to be in compliance with the package�s copying restrictions which are usually outlined in the program�s source code or about or Help sections. A lot of freely available software can be obtained by downloads on the internet. Some can be bought in physical form from commercial retail outlets either online or at a physical location. Many freely available applications have been converted from UNIX to OS/2, Windows 95, 98, NT, 2000 and XP. And other operating systems… If you use an application that has been ported to many operating systems you will be able to carry your skills and data to alternate platforms if you wish to or have to change for one reason or another. “NonFree Applications” consist of commercial applications and shareware applications. Commercial applications are sold outright. Shareware programs may be tried out and evaluated then either not used, uninstalled or a license key purchased. Sometimes shareware programs may be used for free in a home environment but purchased if used within a business setting.Hopefully now the distinctions between these terms bantered around in the Linux software distribution distro and downloads sites will be clearer to you now.

Linux supports file systems like Ext2, Ext3, ReiserFS etc. They follow hierarchical directory structure, where everything starts from a root directory that is represented by �/�. The root directory then expands into sub-directories. As compared to Ext2 file system, Ext3 and ReiserFS are less prone to corruption. It is because they both support file system journaling and can replay journal to recover from unexpected crashes. But in cases of severe corruption, you need to use tools like fsck to repair the file system or ultimately format the partition or volume. To restore the lost data, you need to use an updated and valid data backup. But, if data backup itself gives errors or proves incomplete to deliver the required information, Linux Data Recovery tools can come to the rescue to recover your lost data.

Consider a scenario, you try to start a Linux system and receive a set of error messages as:

�Multiply claimed block�

The boot process fails with this error message and you can�t access the data.

Cause

When your system starts and it doesn�t find the file system in good state, it runs fsck check. This error message is returned by fsck check, when it finds the file system inconsistencies. File system can get corrupt because of unexpected shutdown, virus infection, network errors, hardware issues and other similar reasons.

Solution

To solve the �Multiply claimed block� error, you need to follow these steps:

You need to manually run the fsck command. It can repair file system consistencies like the ones that occur when file system is unmounted or mounted as read-only.

If running fsck doesn�t resolve the issue, you need to reformat the hard disk and reinstall the operating system. This process recreates complete file system structure and also deletes all the data. In such cases, you need to use the recent data backup in order to restore the lost data. But in some cases, data backup can be corrupt or incomplete. To recover data during such circumstances, you can use commercial Data Recovery Linux applications.

Linux� Recovery software are advanced applications that use advanced scanning procedures to safely recover your lost or inaccessible data. Such software are available with interactive interface together with developed features to assist you.

Stellar Phoenix Linux Data Recovery offers powerful Data Recovery Linux solutions. It supports Ext2, Ext3 and ReiserFS file systems based Linux partitions and volumes. The software can be used with almost all Linux distributions as SlackWare, TurboLinux, SUSE, Mandrake etc. It gets installed on Windows (Windows Vista, XP, 2003 and 2000) and the affected Linux hard drive should be connected as slave.

In a Linux system, files, blocks, directories, sockets and other items are referred by corresponding file descriptors. If your system is reporting errors that the file descriptor is bad, one of possible causes is that file system is corrupt and thus, you require restoring from backup. But if backup is not valid enough to restore complete information, you need to use advanced Data Recovery Linux applications. As an instance, you might encounter the below error message with your Linux based system:�Bad file descriptor�You might receive this error while trying to access a file or while trying to boot the system.CausePossible reasons for the �Bad file descriptor� error to occur are:Linux systems use a special file, called /dev/null (also called the null device). This file removes all the data that is written to it after reporting that the write process has successfully succeeded. You might receive the above error message if /dev/null has been deleted or overwritten. You can infer this cause when file system is reported as read-only at the time of booting through error messages, such as�/dev/null: Read-only filesystem�� and �dup2: bad file descriptor�If you get this error message while trying to access a file, the most prominent causes are file system corruption or damaged disk block(s). In such situations, you also get write errors. Solution You need to use these methods to troubleshoot the above behavior:For solving deleted or overwritten /dev/null file issues, you need to replace it with the suitable inode. To do so, follow these steps:Boot the system in single-user mode Mount the /proc file system as:mount -o ro /proc/proc is the dynamically generated file system while boot processMount the file system in read-write mode as:mount -o remount,rw /Delete the /dev/null file:m -f /dev/nullUse correct inode to replace it as:mknod -m 666 /dev/null c 1 3Remount the file system in read-only mode and restart the system To correct file system and disk block issues, execute fsck command. You should run the command when the file system is not mounted. If problem persists, reformat the volume and restore from backup. In case of backup problems, you will need to use Linux Recovery tools. Such utilities perform Data Recovery Linux using powerful scanning algorithms and provide graphically rich user interface. Stellar Phoenix Linux Data Recovery is a comprehensive data recovery tool for Linux-based system. It supports safe Linux Data Recovery for Ext2, Ext3, and ReiserFS file systems. The application provides you advanced features such as, RAW File Recovery, File Filter, Append File Header etc. It is compatible with almost all Linux distributions including Gentoo, SlackWare, Mandrake, Red Hat, Ubuntu, SUSE etc.

Linux Superblock is an important data structure of its file system. The Superblock comprises of basic information, like file system size, type, status (mounted or umounted) etc. The file system� manager uses this information to maintain the file system. The file system size described in Superblock should match with the actual one or otherwise, the system will report the disk as corrupt. In such situations, it is essential that you have a suitable backup of your important data. The solution to such problems may compel you to delete stored data. So, if the backup fails or is unavailable, you may need to use a Linux Data Recovery solution.For example, you can encounter the below mentioned error with your Linux-based disk:�The filesystem size (according to the superblock) is xxxThe physical size of the device is yyy.�The error further suggests that either the Superblock or the partition table is corrupt. Generally, you receive this error after running fsck.CauseThe above error can occur due to one of the possible reasons:The system or an application is trying to write on the disk location of Superblock. The error occurs when the Linux system prevents this action.The Linux Superblock or partition is corrupt.SolutionYou should try following the below mentioned steps to overcome this issue:Boot the computer in single-user modeUse unmount -a to unmount all the partitionsRun fsck to repair all the disk partitionsResize the disk partitions using resize2fs� commandBefore applying the steps discussed above, it is highly recommended to backup your data first. If the problem persists, you can reformat the partitions and restore from the backup later.For any reason if you backup seems irrelevant or incomplete, you are suggested to use a third-party Data Recovery Linux application. These products are exclusively designed to scan an affected Linux disk and extract the lost data. Linux Recovery applications are feature-rich tools with high competency to recover data in each logical crash. Moreover, these software are easy to install and use with self-explaining documentation.Stellar Phoenix Linux Data Recovery is an advanced, yet safe, data recovery application that recovers lost and deleted data from Linux disks.

Canonical, the business arm of Ubuntu, has one of the most promising business models in the Linux world, and also the most misunderstood. First of all, Ubuntu is in a market termed by economists as a perfectly competitive market. This means that it cannot charge any price beyond that which is determined by the market. The only way to make profit, as has rightly been identified by Canonical is to create an ecosystem of products and services around Ubuntu, which would complement the functions of the OS.

This is model of making profit is not new. There are other companies that make money from this method. Give the primary product for free but then create other value added products and services that complements this primary product. To make profit from this kind of business model takes time and a lot of investment. Mark Shuttleworth, the financial backbone of the Ubuntu project rightly knows so and is doing exactly that. Most critics of the Ubuntu distro, are convinced that it’s only a matter of time before Ubuntu also capitulates like its predecessors for lack of funds. They couldn’t be further from reality.

The fact that Canonical after six years of existence is not making any profit does not spell any doom, neither does it mean there is no light at the end of the tunnel. Most of the distros that are always used as yardsticks to tell how Ubuntu is bound to wither away did not have any other strategic business model in place. They only offered a Linux distro and expected to make money from it. Some also did not have a thorough understanding of the market in which they operated. Ubuntu so far has not fallen in any of those traps.

The recent partnerships between Canonical and big shot OEMs like Dell and IBM only goes to underscore the fact that the Ubuntu business model has a lot of potential. Companies like Dell and IBM will not partner a distro that they do not believe to have a future. Their partnering with Canonical to offer Ubuntu only underscores one fact- there is light at the end of the tunnel for Ubuntu’s profitability.

Also, there are those that claim Ubuntu is an ugly, over-hyped distro by mostly fanboys like myself. Well they have the right to their opinions, but a thorough analysis of Ubuntu tells you that it is in the news virtually every other day. Not a day or two passes without Ubuntu being in the news. Count how many times this week that you’ve heard of the name Ubuntu in the news and you will understand why it is popular. As for the ugliness, I believe it takes time to get used to. I also initially disliked the brown, but when I got used to it, I could hardly like any other color or theme.

The fact remains, that Ubuntu, despite all the short comings of its commercial backer like not contributing enough upstream or not giving enough back to the community, is an OS that has the potential to be a market leader in the desktop Linux OS market and whether critics agree or not, Ubuntu will for the foreseeable remain a popular, first choice OS for a lot of people.

Beware of loosing a ton of cash by going to a Linux System Administration training course taught in a classroom.

As a new user, you’ll find that there are lots of ways to get Linux training. And going to a course taught in a classroom is a common method. However, you can save a lot of time, money and frustration if you use step-by-step, self-paced training materials instead.

7 Reasons NOT to Throw Your Money Away Going to a Linux Course in a Classroom

1. The Training May Be Over Your Head.

The “level” of the Linux training may be more complex than you can understand.

Linux Training Tips: Most classroom training starts at an intermediate level and immediately gets more complex. You could be quickly left in the dust and an “Intro to Linux” course may not be available in your area.

Some excellent quality Linux training materials start at a very basic “intro” level and build gradually, step-by-step on this foundation to provide you with the level of training you need. This is rare, but quite possible to find.

2. Poor Instructor Quality.

Unless you call and speak to the instructor, you don’t know the quality of the instruction until you get to the Linux course.

Also, by watching and reading some of their sample Linux training materials you can easily tell if the instructor is going to deliver excellent and easy training.

3. Very Expensive.

Linux courses taught in a classroom are very expensive and when they’re over, they’re over.

As an alternative to this, other self-paced training materials are very inexpensive and you can use them as many times as you’d like!

4. Fixed Training Time.

A Linux class has a fixed starting and ending time and you may loose all of your money if you can’t make it on the day of the training.

You can use self-paced training materials any time and anywhere in the world. And some of these materials include a 30-day, no-questions-asked money-back guarantee!

5. Terrible Classroom Training Materials.

Even extremely expensive Linux courses often include very poorly written classroom materials (course books, ebooks or videos).

You can quickly determine the quality of Linux training materials just by seeing some samples.

6. Fully Devoted Training Time.

You have to devote one or more solid days to the training and you have to get caught up with your work load when you get back!

With Linux self-paced training materials, you can do a bit at a time, like just a half an hour or an hour a day.

7. All of the other expenses.

Beware of the “hidden” expenses, such as travel costs, parking, meals and maybe even hotel costs.

Lately, we have been talking about the Linux Dedicated Servers, in this article I am going to show you the three important tools which are useful for your Linux Dedicated Server Hosting.A fact that most of the people belonging to the website hosting industry knows that the products and applications released for Linux are FREE. The tools listed below are also free to download on Internet.GRUB : Basically, this is boot loader application unveiled under GNU project available for free. If you wish to use 2 operating systems on one single machine, you will need an option to choose the OS you want to run on start of your machine. GRUB is one of the multiboot specification that can fulfil you needs. This is an application which lets you to install and run two different operating systems (OS) on the same machine.You can see the option, only if the GRUB is installed on your Linux Dedicated Server, otherwise the feature will not work. One more advantage of this feature is that you can select various images of the kernel and pass boot time parameters on a single operating system partitions to such kernels.Most of the Linux Dedicated Server Hosting providers will help you to install GRUB boot loader on your server. If not, there is a possibility that you will have to install the GRUB application of your own.TCP Wrapper : This application is also a free tool that you can download via Internet. TCP Wrapper basically acts as a firewall for your own Linux based dedicated server hosting. A fact that the incoming packets are being monitored by the TCP Wrapper, hence it is stated as an acting firewall.On linux dedicated server hacking attacks might be possible, hackers may attempts to login into your server. TCP Wrapper ensures it by checking the external source is aurthorized to connect your linux server or not. If the attempt is unauthorized, the application will denied the login permission.It is also known as a domain computer program, one of the best programs by using it you can keep hackers far away from your Linux dedicated server.Zend Optimizer : It is a free runtime application that allows PHP to run the scripts encoded by Zend Guard. Those who want to run encoded application can freely use this application.Zend Encoder and Zend Guard are few software�s which encode specific files and Zend optimizer is a free linux application software which runs these files while boosting the running speed of PHP applications. Basically, it is an application required by most of the scripts to run the scripts on your linux dedicated server while decrypting and running them on the fly while increasing runtime performance.Maximize your limitations and increase your security by installing these useful tools on your Linux Dedicated Server Hosting.
