New mainboard in Samsung TV and the Secret Service Menu
July 6, 2016

Posted by Roel in : Technical , add a comment

I repaired a broken Samsung TV (UE55ES8000) last month, however the same instructions should apply to other Samsung models.
The TV made a ‘clicking sound’ all the time and couldn’t turn ON or OFF. The screen stayed black. My first thought was the Power board, a dried capacitor, a (physical) broken part on it or a software problem.
I took the TV from the wall, removed the back cover of it and saw 2 boards: a Power board and a System board. No damage, No dried capacitors, No black/fried parts.. I even tried to clear the EEPROM by shorting the VCC and SDA pin on the systemboard but No success..

Read below how I fixed it.

Zehnder/StorkAir MX110 Roof ventilation
February 18, 2016

Posted by Roel in : Technical , add a comment

I needed a proper roof ventilation to cool my server room. Noice (dB) and power usage are the most important factors for me. I tested many options and finally bought a Zehnder/StorkAir MX110 Fan.
This fan is really quiet, has low power usage and you can buy these quite cheap at online auctions, marketplaces or Ebay (around €150-250).
New price is about € 1000,- or even more, depends on the exact model.

Since I want to control it using my own domotics (via KNX, Datec 0-10v Analog Actor based on a temp. sensor), I could grab any model since they all have the same hardware. Other models (MX110 ZMV, WS,..) add a pressure sensor, temperature control,..etc. which I don’t need.

Pinout for RJ45 cable between Moxa Terminal server and Cisco/HP Console port
July 8, 2015

Posted by Roel in : Technical , add a comment

I recently build an Out-of-Band (OOB) management network for Utrecht University with Moxa Terminal servers (CN2610-16-2AC).
The Moxa Terminal servers had all RJ45 (serial) ports. However, connecting it with a normal network cable, a cross-cable cable or a Rollover cable didn’t work.
I found the pinout and made a drawing of it in case you ever need it:)

SQL Server + FileStream + IFilters

I’ve scanned all my documents (incomming invoices) in TIFF but also have a lot of documents in PDF and DOC(X) format. Now when something gets broke and I need to return it to the shop I’m often looking for that invoice, sometimes I don’t even know at which shop I bought it. Imagine I could just type: “HP 8000” or “light bulb” and it shows all documents with those words on it, I find the document within a second and print it out.
I was trying to get this to work the past years but never succeeded so I gave it one last try and now it works!

Cisco SSL-VPN problems after KB2585542
January 14, 2012

Posted by Roel in : Technical , 2comments

Today I noticed that some Windows 7 clients had problems to connect using Cisco’s AnyConnect VPN Client (SSL-VPN).
After a few hours troubleshooting we noticed that Windows Update KB2585542 was causing the problem.

The clients were not even able to see the website (on a Cisco Router) which hosts the Anyconnect client installer. When trying to connect using the Cisco AnyConnect client, it feeled like it timed-out.

How to Backup/Restore Avaya to IIS7.5
October 17, 2011

Posted by Roel in : Technical , 25comments

In IIS7 and IIS7.5 which runs on Windows Server 2008 or Windows Server 2008 R2, it is not possible to use the WebDav PUT command without ‘authentication’.
This is a problem for your Avaya VOIP phones. Avaya uses the PUT command to backup a phone configuration and to store contacts.

Now, there are 3 possible options:

  1. Install Apache on Windows or Linux. I know many of you guys don’t like this…Especially because you need to configure and update/patch it.
  2. Use a WebDav server like IP Tel from Avaya. However, that program looks like a Windows95 program,.. is it supported at all. ?
  3. Install my Avaya script / workarround! I’ll tell you how it works below.

Migrating from IMail 2006 -> MDaemon 11.0.3
July 25, 2011

Posted by Roel in : Technical , 1 comment so far

I wrote some scripts to migrate from IPSwitch IMail 2006 (IMail 9) to MDaemon 11.0.3.

Because IMail and MDaemon have some differences in logic, I cut my migration into several parts.
Below you’ll find a step-by-step IMail to MDaemon migration including the scripts I used/wrote! (more…)

Gira installer tips!
June 15, 2011

Posted by Roel in : Technical , 2comments

Recently I was installing some additional RJ-45 wallmounts in my house.
I was really annoyed of Gira’s ‘solution’ to mount a Panduit CAT6a (10Gbit capable!) keystone.

I needed a screwdriver to get my cable back from the Gira wallmount. Many installers face the same problem.
I found a simple solution by replacing the plastic Gira frame by a steel Jung frame!
It fits much better, no more friction and easier to install!
