Creating Images Of Your Linux System

Have you ever had the problem that you have set up the "perfect system", and now you want to back up this system before you make changes to it so that you can restore the original state if you changes are not satisfying? Or are you a system administrator in a large company where you have to maintain hundreds of Linux machines that run exactly the same software, but are sick of installing each machine manually? Or did you develop a Linux-based hardware appliance, and now you want to sell it in big numbers on different hardware platforms (i.e., different hard disks, etc., not different processor architectures!) without having to maintain an image for each platform? Or do you want to distribute this solution to your resellers overseas, so that you do not have to ship expensive hardware and your resellers can sell their own hardware*? This is where SystemImager comes into play!

Alternative Screenshot Methods

Are you trying to take screenshots in Linux but don't want to use KSnapshot or the built in Gnome Screenshot Utility? There are quite a few ways you can take screenshots in Linux. The thing is, most of them are unknown. It's almost like the ability to take a screenshot is the best kept secret in Linux. So if taking screenshots is something you need to do on the fly or from a shell, or in a GUI that doesn't have the utilities you on.


This is a free, GNU LGPL, zip program for Windows that also supports many common Linux compression formats.

MS-DOS 7.10 Download

MS-DOS 7.10 is an standalone and independent OS actually, which has a lot of features. It fully supports large hard disks, large memory, FAT32 drives, Long File Names (LFN), etc. It has lots of enhancements over older versions of DOS, such as MS-DOS 6.x. And at the same time, it offers excellent upward/downward compatibility. With it, you can run both Windows 3.x GUI and Windows 9x (95-98SE, a.k.a. Win4.x) GUI on top of MS-DOS 7.10.

Is this for real?
