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.

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.

Games for GNU/Linux

  • It looks like we may be getting a Planescape Torment Enhanced Edition
    Back in January Beamdog was looking for testers on a new game. Now the Planescape website has a countdown timer. It's legitimate too, as tweeted by the Beamdog and the D&D twitter accounts.
  • RTS game 'Deadhold' could come to Linux, considering an experimental Beta
    The developers of Deadhold [Steam, Official Site] want to support Linux and they are thinking about releasing an experimental Linux Beta.
  • Ten amazing Linux games you can play without WINE
    Those of us who have taken up the mantle of a Linux gamer know that our path is rarely easy. For a long time, few games were released for our chosen platform. Those that were shipped riddled with bugs, compatibility issues and rarely worked out of the box. Getting games to work require using WINE and deeply complex almost arcane workarounds to force windows games to work on our quirky systems. Unfortunately, games rarely worked well and usually required hours of complex tweaking in order to get them to function properly. To top this all of, there were graphics driver problems, optimization issues, peripherals rarely worked out of the box and our lives were generally difficult.

Samsung Galaxy Tab S3 Review: Finally, an Android tablet built with enterprise users in mind

Show me an Android tablet and I'll show you a device that has yet to live up to its full potential. Google's Play Store lacks a wide selection of apps that support a tablet's larger display, with most apps only expanding the phone interface, in turn looking horrible on the smaller screen. In addition to the lack of quality apps, Android tablets have lacked key accessories such as a keyboard. For the most part, Android tablets have been relegated to a device used to catch up on Netflix or to entertain kids with games. Read more
