Remote administration of VMware Server 2
VMware Server 2.0 implements the new (well, for free Server users at least — ESX and ESXi have had it for ages) web interface for administration. When you install the server the listener for this is configured for ports 8222 and 8333. The former is only reachable if you’re coming in locally. Remote users have [...]
Webcam picture too dark
So this is a problem I had with Skype. Most Linux apps that use a webcam actually provide a way to adjust brightness and contrast. Not Skype. Probably because this requires root privileges, and they know no self-respecting Linux admin is going to give them that.
The fix is actually pretty easy.
First, to see immediate results [...]
Linux memory utilization
Why is that Linux server using 96% of memory?
This question has come up a lot lately because we’re finally monitoring mundane stuff like memory utilization globally.

A good article on this is Understanding Virtual Memory by Norm Murray and Neil Horman, published in the [...]

Using Sun’s JDK rpm on CentOS/RHEL

Since returning to CentOS from Ubuntu I decided to give the Sun rpm a try instead. The basic process was the same, the main [...]
Skype on a CentOS 5.3 Thinkpad T61
This will be a short post more of the “strategy for how to make this happen” sort.
If you’ve read my recent posts, you’ll see that I’ve spent my spare time configuring CentOS 5.3 on my Thinkpad T61. For the most part this hasn’t been that difficult, although time-consuming.
Most of the time has been spent having [...]
Thinkpad T61 Internal Microphone under CentOS 5.3
Linux audio has always been, and continues to be, a creature from the depths of hell. There’s no nice way to say it. It sucks. While it looks like many problems are now being solved by implementation of the pulse audio sound server, it’s still only found in short term development distributions like Fedora and [...]
