One of the parts of my day job is dealing with and managing our HPC cluster. This is an 8 node Rocks cluster that was installed maybe a week after I started. Now I was a bit green still at that point and failed to get a better grasp on some things at the time, […]
I promised that I would try the full install version of CentOS 5.4 desktop on my thinkpad and didn’t want to disappoint, so here it is… I actually had a really hard time with this one. That is not to say that I believe that there is an issue somehow with CentOS, but certainly something […]
In my continuing saga of Linux distributions and testing on my trusty, crusty Thinkpad T23, I tried out CentOS 5.4 Live. Now many of you already know that I have developed a sort of love affair with CentOS as a wonderful alternative to paying for enterprise class Linux. Then again, I am RedHat certified, so […]
Last night I finally finished cutting all my server services to their new residence on Pukwudgie (my spectacular CentOS 5.3 based server VM). I turned off my old Thinkpad server, which has been doing the job reliably for over 2 years, rebooted pukwudgie just to make sure everything starts up correctly unattended and that was […]
Lately, I have been slowly migrating my server services from my ancient Thinkpad server to a VM on some real server hardware.

Late last ‘week I noticed that my new nagios server was not responding anymore. Well, I checked it and it was down. Not only that, it was a vm on my test server and the entire server was down as well. Arrrgh. Usually I use this as a foray to tell you all to remember […]
I always push VMWare because I use it a *LOT* and believe it to be a superior product. My friend Dann was no exception. When it came time for him to get a new server I suggested he could do several virtual machines on one good physical box and save his resources. He did the […]
Even though I wrote and use OSM I also use Nagios at work (along with OSM). Actually, I administer Nagios there, however I have never actually installed and configured it. It was in place before I started there. That being said, my manager asked me how to get it installed and running today, as he […]
Just a quickie tutorial on how to set up a web based subversion server on a CentOS server in a hurry. To start with you need a CentOS 5.x install with a working web server. # yum install subversion mod_dav_svn Pick a directory where you want to house your repo. We’ll say for argument mine […]
