If you are using Nagios to monitor remote servers, you have more than one method to execute checks, including the use of the check_by_ssh plugin. Vincent Danen tells you how to set up this plugin and the best way to secure it.
This tutorial explains how you can set, change and reset (if you've forgotten the password) MySQL root passwords. Time and again I see problems like mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: YES)'. So I thought it's time to remind you how to solve MySQL related password problems. If you are just looking for a quick fix how to reset a MySQL root password you can find that at the bottom of this tutorial.

I am admittedly not a normal computer user. I don't always fully grasp what's going on deep inside the operating system, nor am I always confident I'm clear on how an application is working with all of the services it requires to function. But I find it interesting, even if just on the most simple, conceptual level.
The majority of computer users want their machines to "just work." And though I like seeing how my hardware and software interact, it is preferable to have things "just work," so I can get what I need done, and then spend the time I saved doing so leisurely poking at my application's innards. There's an inherent danger in the "just works" philosophy, however.
GNU/Linux offers a bewildering variety of flavors -- or distributions, as they're called. To a newcomer's eye, many of these seem virtually identical to each other.
Yet, the more you learn about a distribution and the community that surrounds it, the more different they become. Here, in alphabetical order, is a list of the seven distributions that have most affected GNU/Linux as a whole:
Since earlier this year we have been waiting for AMD to release documentation and/or code on the ATI R600 series concerning 3D acceleration so that the open-source Linux drivers can begin to support the newer ATI graphics processors. It has taken longer than expected for AMD to complete and release this information, but it's now available.

When it comes to Linux, most U.S. headlines involve Canonical, Novell or Red Hat. But another Linux distribution — from Mandriva S.A. of Paris, France — is making a name for itself in the global IT channel. Consider this: More than 2,000 IT partners have lined up to back Mandriva, up from about 1,200 in 2007.
