Cloning is nothing but the copying of the contents of a server hard disk to a storage medium (another disk) or to an image file. Disk cloning is quite useful in modern data centers for:
- Full system backup.
- System recovery.
- Reboot and restore.
- Hard drive upgrade.
- Converting a physical server to virtual machine and more.
In this post, I’m going to list the Free and Open Source Software for Disk Imaging and Cloning that you can use for GNU/Linux, *BSD and Mac OS X desktop operating systems.
These are full-featured open source software products, free as in beer and speech that I started to use recently. Vivek Gite picks his best open source software of 2013.
I usually use GIMP (the “GNU Image Manipulation Program”) for editing photos, changing colors, resizing photos, applying significant effects and more. It is a free software alternative to Adobe Photoshop. It is also quite popular with graphics artists and webmasters who wants to edit digital images. GIMP is not just a Linux specific program. It works on all leading operating systems, i.e., Mac OS X, MS-Windows and Unix variants. However, like many other powerful open source software, GIMP can be difficult to master. There are many options and plugins. So if, you are looking to learn or master the GIMP program, give The Book of GIMP a try.
Linux on the desktop is making great progress. However, the real beauty of Linux and Unix like operating system lies beneath the surface at the command prompt. nixCraft picks his best open source terminal applications of 2012.
Nmap is short for Network Mapper. It is an open source security tool for network exploration, security scanning and auditing. However, nmap command comes with lots of options that can make the utility more robust and difficult to follow for new users.
The purpose of this post is to introduce a user to the nmap command line tool to scan a host and/or network, so to find out the possible vulnerable points in the hosts. You will also learn how to use Nmap for offensive and defensive purposes.
Do you need a simple open source cross-platform command line tool that converts web pages and HTML to a PDF file? Look no further, try wkhtmltopdf.
Fsh is an entertaining interactive desktop aquarium. It was created as an alternative to Gnome easter egg called “Free the fish”.
OS X Mountain Lion has been released and available for download. This new release comes with over 200 new features such as Twitter integration, Apple’s Game Center, iMessage services, and a new security feature called Gatekeeper to protect users from malware. However, new operating system is not compilable with all mac computers.
