I was asked to create 365 (1 year) of WiFi (daily) guest access accounts, and export them to CSV.
Of course I didn’t want to create them by hand.. this is where PowerShell came in. I used the following PowerShell script to create random WiFi guest accounts:

HP Insight Management Agent reports that unused VMware nics are down

When you don’t use certain nics on your VMware hosts, HP Insight Management Agents may report that the nics are down. Which is the natural behavior of these clients.
The system management homepage on those hosts looks like this:
Jeenode infrared project part 4: a better home…
June 22nd, 2010

Agreed, a breadboard looks nice and “hacky”. But, it doesn’t really fit nicely into my interior :-)
It’s time to give the Jeenode infrared sender/receiver a better home!
The main ingredients to get this going are:
- Hot glue (love that stuff)
- Solder
- Some wires
- A Jeelabs carrier board with case
- A drill
- A lot of patience…

Today I had a nice issue. One of the servers at work suddenly had a “black” Windows startup screen.
It looked like this:

I have just powered my first Jeenode with solar power.
This node has been running for 5 days now.
The solar panel is one normally used to charge cell phones.
It supplies 5v and has a accu pack of 2800mah, this should keep this node running for quite a while…

Jeenode infrared project part 2: going wireless

In part 1 of this series I blogged about receiving infrared signals using an IR led. This blog post will focus on getting the signals up in the air (and off course receiving them on the other side, in my case my home automation server with a Jeelink attached)
The Jeenode’s have a HopeRF wireless receiver/transmitter on board, which makes life easy.

Today I received new Jeenodes, so it’s time for more electronics fun :-)
One thing that I head in my head for a while was an infrared receiver and sender.
I want it to be like an advanced Logitech Harmony, the main downside on the Logitech Harmony is that there is no status tracking.
What happens if the TV is already on, and your Harmony tries to turn it “on”? (right.. *poof* your TV just got powered off)
So, in my opinion an ideal remote has integration with my home automation system, and keeps tracking of device statuses (I can use Plugwise for example to determine if my TV is powered on or off)
And what to think about turning on the TV on at your preferred time on your preferred channel? (imagine waking up, stepping inside the living room and have the morning news ready for you.. )
Enough introduction, let’s dive into the hardware…

Microsoft has released a RTM version SCSM (System Center Service Manager) on MMS (Microsoft Management Summit). A product i’ve been waiting for, for quite a while.
I just finished setting up a lab environment, and I’m sharing my experience in this blog post. If you want to know more about service manager, check out this site: http://www.microsoft.com/systemcenter/en/us/service-manager.aspx

Sometimes it’s a bit tricky to relate events generated by the SCCM management pack for SCOM to real SCCM errors.
This article helps you to trace down the real SCCM error by using a real world example..
