This article shows how you can install the PowerDNS nameserver (with MySQL backend) and the Poweradmin control panel for PowerDNS on a Fedora 12 system. PowerDNS is a high-performance, authoritative-only nameserver - in the setup described here it will read the DNS records from a MySQL database (similar to MyDNS), although other backends such as PostgreSQL are supported as well. Poweradmin is a web-based control panel for PowerDNS.

Colin Watson (Ubuntu Development Manager) just announced on the Ubuntu-Devel mailing list that you can now perform installations with a BTRFS root filesystem using the latest Ubuntu 10.10 Maverick Meerkat daily iso.

Your prime directive as a system administrator is to keep those systems whipped into shape and running without interfering with user’s daily operations. Sometimes the systems put you in a difficult position when their disks overflow with files. The simple solution is to remove files. But, what if you can’t do that? You have to add disk to your ailing system. But, how and where do you add that space? And, how do you keep this from happening again?

This guide explains how you can install and use KVM for creating and running virtual machines on a Fedora 13 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

Earlier this week AMD released the Catalyst 10.6 driver that on the Linux side of the table had finally made use by default of their new 2D acceleration architecture, offered official support for Red Hat Enterprise Linux 5.5, and formalized their OpenGL 3.3/4.0 support. Since the release of the Catalyst 10.6 Linux driver, we have been running a new set of tests on their new ATI 2D acceleration architecture, but the results are not what you may expect when compared to the open-source ATI Linux driver.

Bisgi themes just won't stop improving. They stunned everyone before with their incredible collection of themes downloadable via bisigi PPA. Now a new theme called ECO is released which for me is the best so far. Another important USP of Bisigi themes is that, they include everything.

Its collaborative, consensus-based development process, affectionately dubbed "The Apache Way", is one of its secrets to creating dozens of high quality, industry-leading software products that all began with a single project.

The default menu application in Ubuntu is functional, but it is also down to earth basic. GnoMenu tries to replicate the looks and functionality of KDE's Menu application. And I have to say, it almost does. GnoMenu comes with a number of themes and a easy to use configuration menu.

Apple's iPad was hardly the first tablet to appear on the scene, but it is unquestionably responsible for the recent spike in tablet development. Now it looks as if Ubuntu — the Linux distro everybody loves to hate, but uses anyway — will be entering the field as well.

The Wine development release 1.2-rc4 is now available. The source is available now, Binary packages are in the process of being built, and will appear soon at their respective download locations.

When you work with large amounts of photos, it can get tiresome to have to manually manage the file and directory structures. To help resolve this, many people use photo managers such as Picasa, DigiKam, and iPhoto. There are several options for Linux, so we’ve decided to check out each of the major photo management options for Linux to see exactly what each one offers. Today we’ll be comparing Picasa, F-Spot, Shotwell, DigiKam, and Geeqie.

Eucalyptus Systems is set to gather reseller partners old and new in San Francisco on June 22. The reason: It’s time for Eucalyptus to lay out where their open-source cloud platform stands, along with potential channel partner opportunities. Here’s what to expect.

I can't say that Xfce spin is slower or faster than the LXDE spin of Fedora 13. The thing to remember about both of these Fedora spins is that it's easy enough to add any or all of the applications from one spin to another. I'm not sure exactly what the LXDE spin's policy on GTK 1/2 apps are, but on my hardware it looks like it'll come down to personal preference and not vast performance differences. The more I think about it, I'd be very happy to have both of these "spins" on one installation, and if there are metapackages for both the Xfce and LXDE spins (and I'm fairly sure there are), that's just what I might do.

Last week prior to heading over to Germany for LinuxTag, I had ran a new set of ATI R500 Gallium3D benchmarks with an ATI Radeon X1950PRO graphics card and comparing the latest Mesa/Gallium3D graphics driver performance in the Mesa 7.9-devel Git code with both the Gallium3D and classic Mesa DRI drivers to the older Mesa stack found in Ubuntu 10.04 LTS. The ATI "R300g" driver as its known continues to advance, and over the past week this driver has pushed forward even more. Here is another set of ATI Gallium3D tests.

Running Linux system inside a chroot environment allows a system admin to decrease an impact on a production server when the server gets compromised. Change root will change root directory to all current running processes and its children to a chroot jail. Testing of various package installations and server configuration in a chrooted environment can be another handy way how to utilize a chroot jail. This tutorial will provide a reader with step by step guide on how to install Debian with ssh daemon inside chroot environment using debootstrap.
