There are a lot of reasons you might want to manually set your MAC address for your network card. I won’t ask you what your reason is.

To change this setting, we’ll need to edit the /etc/network/interfaces file. You can choose to use a different editor if you’d like.

Partition Image is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example), … Partitions can be saved across the network since version 0.6.0.When using Partimage, the partitions must be unmounted.

Partimage is very useful in the following situations

First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you don’t want the image to use hard-disk space.

This utility can be used to install many identical computers. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Image’s restore function.

Backup and Restore Linux Partitions Using Partimage


If you want to create a system that is similar to a different system you have already set up, it can be difficult to remember each and every package you had installed.This method works best when you are exporting to and importing from the same distribution and, specifically, the same releasefor example, exporting from Ubuntu Dapper to Ubuntu Dapper or ubuntu edgy to ubuntu edgy.

Ubuntu uses the APT package management system which handles installed packages and their dependencies. If we can get a list of currently installed packages you can very easily duplicate exactly what you have installed now on your new machine.

Clone Your Ubuntu installation


Creating an optimal flexible layout (OFL) for a Xen cluster is more difficult than setting up a standalone box with just one environment running on it. This is especially true if you’re planning to let inexperienced users play on the boxes with escalated privileges, or if you are building your cluster to cope with disparate uses on the VMs. Databases, Web servers, and compute boxes can be difficult to manage in their own separate systems, and they’re much more difficult to manage in a Xen cluster if the sys admin of each VM is unaware of the load others are putting upon the architecture. The admins may not have sight of the other VMs’ hardware usage patterns and could encounter difficulty investigating bottlenecks and stoppages inside their own VMs caused by contention on the hypervisor’s other VMs. What is gained by using Xen in terms of flexibility and efficient use of hardware could easily be lost to complexity if initial plans of usage are poorly developed or inadequately tested. Gibbins shows how to set up a self-managed Xen cluster.

Share your love for free software

Yes, we love Free Software and this readily means that we love technology, people, social equanimity, and the various meanings one may take on for the word “freedom”. We care about it and we all want to bear witness of the growth and consolidation of new projects, and the progress of elder ones into full-fledged solutions driven by healthy and thriving communities. Free Software communities are inherently diverse and put together people with different motivations, expectations, and interests. Some are there to make friends and advance their technical and social skills, while others want to pursue the dream of an open world or even have Free Software as their daily paid job. In spite of such a diversity, one thing unite all of us in this Free Software odyssey: we love what we do. Read more

  • Handheld Emulation: Achievement Unlocked!
    I love video game emulation. My favorite games were produced in the 1980s and 1990s, so if I want to play them, I almost always have to emulate the old systems. There is usually a legal concern about ROM files for games, even if you own the original cartridges, so I'm not going to tell you where to find ROMs to download or anything like that. What I am going to share is my recent discovery of the perfect handheld gaming system. Oddly enough, it was never intended to be an emulator.

  • India Asks Tech Companies To Use Open Source Technologies For Connectivity
    A day after taking a tough stand on Facebook’s Free Basics and banning it from India, TRAI (Telecom Regulator Authority of India) has also given a cue to the tech giants like Facebook and Google over the use of open source software. TRAI has hinted to these companies that their connectivity framework would only be accepted in India if they followed an open source approach. [...] Ram Sewak Sharma, who is the current chairman of TRAI, has clearly put a stress on using open source technology over a company specific product in making the internet reach to the remote areas. In a recent summit hosted by the Internet and Mobile Association of India, he said, "I don’t like to comment on a specific product. But India has adopted an open source policy and open API [application program interface] policy. The whole objective is that there should not be a situation of a vendor lock-in."
