Technology And Computer|

Linux has gained enough popularity for its new and updated features. Usually, this operating system is considered as the most regularly upgraded application and hence, with Linux, many users feel that they are having the advantage of using the most recent technologies. Even some feel that Linux is free from virus attack and other data loss problems. However, it is the fact that the technology has nothing to do with data loss. Linux systems also undergo severe data loss situations, leaving the system drive completely inaccessible. Under such cases, you can take the help of any Linux data recovery software to retrieve your data back.

Data loss in Linux can be in any form, starting from the accidental/intentional deletion, formatting of the media, virus/malware attack, operating system malfunction, file system corruption or any other software/hardware contradiction etc.

Whatever, be the reason behind the failure of the Linux system, it is your valuable data in the media which suffers the most. Some data can be urgently required, some are the result of months of research work and some even can never be recreated. In such situations, loss of them caused severe business loss and mental trauma.

Among all the odds, if you have taken regular backups of your data, you always resides at the safe side and can restore the data from a recently taken valid backup. But, if you have not taken any recent backup, you are under serious trouble for sure.

But, among all these troubles of data loss, the good fact is that data from the troubled Linux drive never gets lost permanently. Therefore, if you can take strict measures to avoid overwriting the data in the drive, and run any efficient Linux file recovery utility, then, all you lost data can be easily recovered back.

These undelete Linux applications can work on any Linux operating system based computer system and can recover your lost, deleted, formatted or inaccessible data effectively. These utilities have been developed with many advanced scanning algorithms to dig into the storage media throughly and are completely read-only in nature. Moreover, with detailed instructions at every step and highly graphical user interfaces, they are pretty easy to use even with much technical knowledge.

There are various techniques available in order to safeguard your valuable data, and disk mirroring is the most popular among them. It is the process of create an exact replica of all the data stored on your hard drive. You can easily convert your basic hard drive volumes to mirrored volumes, which replicates your data to prevent any sort of data loss situations. On Linux operating system-based computer, you can convert your linear logical hard drive volume to the mirror logical volume using ‘lvconvert’ utility. However, you should play safely while converting a Linux volume, as interruption to the process may cause hard drive failure and data loss situations. At this point of time, you need to opt for Linux data recovery solutions to get your precious data back.

The lvconvert is an inbuilt utility of Linux operating system that enables you to change a linear Linux hard drive volume to mirror logical volume. You can also use this utility to remove or add disk logs from the mirror devices. The command line utility supports various options or parameters to perform specific task. Some of the most common parameters of this utility are as given below:

-m, –mirrors Mirrors- This option specifies degree of mirror that you want to create. For instance, ‘-m 1′ converts original Linux volume to mirror logical volume with one linear volume and one copy.

–corelog- This parameter tells the tool to switch mirror from employing a persistent (disk-based) log to in-memory log. It is possible only if –mirror argument is of same degree of mirror that you are modifying.

-R, –regionsize MirrorLogRegionSize- It divides the mirror into various regions of defined size in MB (megabyte).   

-s, –snapshot- It creates the snapshot from an existing Linux volume using another volume with same origin.

-Z, –zero y/n- This option controls zeroing of first KB of information in snapshot. The snapshot is not zeroed if volume is set to read-only.

Before you convert the volume, you must backup all your significant information. If the process fails, you can not access Linux hard drive volume and stored data and need of data recovery Linux arises. Linux recovery is best possible using advanced and powerful third-party applications. Linux data recovery applications ensure safe and easy recovery in all data loss situations, with read-only conduct and rich graphical user interface.

Stellar Phoenix Linux Data Recovery software recovers lost data from lost, deleted, corrupt, or inaccessible hard drive volumes. The software supports recovery from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system, including Red Hat, SUSE, Debian, Fedora, and more.

Ever wondered what using an operating system other than Windows would be like?  Well, there are options!  Most people don’t realize they can install a completely different operating system on their computer.  They trudge along in misery using Windows XP, while they could be using a newer, faster operating system that does everything Windows does and more.

So what is this other option and how much does it cost?

Linux.  And it’s free.

Free?  Well, you say, if it’s free it probably isn’t that great.  You’d be surprised just how polished and fast it runs, even on old hardware.

So where can I get Linux?  You can download it from a number of places.  Here is a link to the Ubuntu Linux OS downloads page.  Ubuntu is one of the better Linux “flavors”.  Yes, there are a bunch of different Linux “distros” to choose from.  Some are made for specialized applications, like audio production, or for use on older hardware.  Others, like Ubuntu, are for end users looking for a nice desktop OS.

Once downloaded, you’ll need to install it onto your computer.  This is where things get tricky and most people will hit snags here.  First thing to remember is don’t do any harm to your current Windows setup.  The best bet is to install Linux onto a separate hard disk, or onto a flash drive for testing purposes.  If you aren’t too technically savvy, then your best bet is to hook into a local Linux user group, a group of Linux fanatics in your area, who’d probably love to assist you.  Do a search for a linux user group in your area here.

Once installed, where do I go for support?  Again, this is where Linux shines.  Rather than calling Microsoft support and getting some person sitting in a call center in another country reading off of a script, you can tap into the community of Linux users for help.  They are usually a very friendly bunch, willing to help you make the jump to Linux.  In the past, Linux had a reputation for users who were a little rude towards new users, but lately things are changing and the Ubuntu user forums are especially friendly to new users.  

The most important thing is don’t give up when you hit a snag.  Once you “get it”, Linux is a wonderful, powerful alternative to Windows.

Linux web hosting (often referred to as LAMP – Linux, Apache, MySQL & PHP) solutions are suitable for webmasters who use Linux hosting features, such as Perl programming, PHP programming and MySQL database.

Windows Web Hosting gives a company the capability of designing web sites using the ever-popular Windows Operating System. This allows development using technologies such as Active Server Pages (ASP), COM, and the newer .NET infrastructure.

Advantages of using Linux based web server compared to Windows based web server:-

1.Stable:-
Linux operating system is very stable and robust.  A web site hosted on a Linux operating system will have very high up-time.

2. Low cost of ownership:-
Linux OS comes free of cost.  Also, it has fully fledged server, and desk top applications that come free with the OS. These server applications (such as FTP, Web Server, DNS Server, File Server etc.) are also very stable.

3. Easy to move between hosts:
A web site designed to host on a Linux based web server can be hosted on a Windows web server easily, where as the reverse is not always true.

4. Most widely used : Linux/Unix based web hosting is most widely used compared to Windows based web hosting.

5. Scalability: A web site designed for compatibility with a Linux/Unix based web server meets the scalability requirement easily without making any site wide design changes.

Disadvantage:-
Linux based web server is not fully compatible with Microsoft technologies. If you are using any specialized applications or VB for development of your web site, it is preferable to host with a Windows based web server.

Both these web server are used by users for different purposes and the selection of the web hosting depends upon the nature of the website or business. Linux server administration and Linux server management has been more effective for complex websites, where as Windows servers are used for sites which needs different configuration.

Most individuals are acquainted with the operating system of Windows, that is widely used all over the planet and get the main placement in software area. What about attempting Linux? It’s also a kind of operating system, similar with Windows, but might be downloaded freely from internet.Click Here To Grab Your Copy

Linux is important because it is more secure then other operating systems. As I have written above that Linux is a server based operating system and Linux can handle most complicated servers like MAIL server and MAILER server. And in that kind of servers we need more security and Linux is more secure. Linux is secure because VIRUS can not harm Linux. And Linux is totally free. That is why most of the companies required Linux.

Linux GUI Application Development for Windows Programmer

Moving from windows to linux development you are confronted with a myriad of options. QT vs GTK+? Which language should I use: c/c++/java/perl/tcl/python/ruby or javascript? Should I use a commercial/proprietary layout/rad tool (QT or Kylix) or an open source one? What about Mozilla? My background was primarily in programming Visual Basic and Lotus Notes(Basic, Java, c/c++ api.

The Linux desktop

Linux has recently made huge progress in the desktop area. Corporate interest peaked as Microsoft tighted its monopolistic screws with its new licensing program earlier this year. However, there are a few things that I think still need improving in top grade distributions such as Mandrake or Redhat. This list was developed over a year of watching my wife using the kde, gnome and fluxbox interfaces primarily in Mandrake 8.x.

However advanced the technology may be and whatever precautions we may take, data loss is almost inevitable. Though Linux operating system is often improved upon its previous versions than any of its counterparts, still there are a number of reasons, for which data can be lost in a Linux operating system based computer. In a Linux computer, the fstab (/etc/fstab) and mtab (/etc/fstab) are the two most crucial directories. Without these directories, the operating system could not be able to locate neither the existing hard drive volumes nor the mounted drives on your system. For this reason, the system fails to boot and all your data in the hard drive becomes inaccessible. In such situation of data loss, you need any Linux data recovery software to recover back the lost or inaccessible data.

Facts about ‘fstab’ and ‘mtab’ directories:

• The fstab or ‘file systems table’ is a system directory within the Linux operating system. This system configuration file contains information about all the available hard drives and volumes attached to the system. The file tells, the way, hard drive volumes are initialized and integrated through the file system. Moreover, it lists the details of the file systems, which are accessed by the ‘fsck command.

• The mtab or ‘mounted file systems table’ is also part of system configuration and lists all the currently mounted file systems on your Linux system. The file retains every detail of the mounted volumes, that is whether mounted manually or automatically and is automatically updated once the mount command is triggered against any drive or volume.

Sometimes, while accessing the Linux drives or the mounted volumes you may come across error messages related to the mounted file system and all the files and directories become inaccessible. The error message that you may have encountered can be read as below:

“Cannot read table of mounted file systems”

The above error is caused due to the corruption of ‘fstab’ or ‘mtab’ directories. Thus, the file system fails to mount and the data remains inaccessible thereof.

Such situation of data loss can only be dealt by any efficient Linux data recovery utility. These applications are meant to recover the lost, deleted, formatted or inaccessible data from the Linux file system based volumes. Moreover, these helpful utilities are completely safe to use and come with detailed instructions, so that can be used without any prior knowledge.
