Background Today, I finally took the time to update a Cacti Data Query which I wrote a while back. When I took a look at it, I found out that it was never actually working for other people strait out of the box. This data query graphs BGP prefixes, messages received and messages sent. I

Background In my original post KVM Virtualization 101 and my second post KVM Virtualization 102, I explained some basic commands that are necessary to get on using KVM and some features for tuning KVM. In this article I move on to some of the more advanced problems when converting existing Linux machines from a
Background In my original post KVM Virtualization 101 I explained some basic commands that are necessary to get on using KVM. In this article I move on to some slightly more obscure topics in using KVM. Routine Operations CPU Type When you are operating in a KVM virtual machine the processor will report
Background In Part 1, I described a method of documentation where the introduction of the system is made using the documentation. This builds consensus, enculturates an operations group, and provides a platform unto which more automation can be built. In Part 2, I elaborated on the ideas of Bootstrapping & Rooting, Self Service Culture, and

Recently, I listened to an O'Reilly webcast called "The Myths of Innovation" where Scott Berkun discussed the concept of a lab. He showed a picture of Edison's lab which showed wooden tables, lamps, and beakers. Systems administrators are also inventors. We are required to script, program, and configure exotic servers and equipment. To discover new solutions, we need a lab. This is especially true with cloud computing and virtual infrastructure where machines are created and destroyed in a very transient manner. You need a lab to track all of the successful and failed experiments.

Abstract Linux Systems Administration for Power Users: This presentation was created for the Oct, 2010 Akron Linux Users Group. This presentation is given from the angle, what do I do when I am in a bind. At some point all computers break. Since Linux is fairly stable, it can be intimidating when something important does
