Ricoh and LDAP with Active Directory

Ricoh Multifunctionals working with LDAP to an Active Directory are fun!

When it works.

I ran into a problem with Ricoh Multifunctionals and the connection to an LDAP server.

If you do too at some point run into trouble setting up these printer-scanner-fax-whatnots, make sure you check the following:

- Set a DNS server, better, set two.

- Create a domain, first entry is the descriptive name of the setting, second the ip address of a DC, third, the name of your windows domain.

Not setting a DNS server makes the check on LDAP fail for some reason, even if you connect to an IP address!

Specify your LDAP location (where to search) in your Active Directory such that it looks like the following:


Don’t use “-marks.
Don’t use spaces.

Last, you may want to change the search setting ID from cn into displayName so it can look up names in the directory.

Something like this:



This should do. I hope that perhaps this helps you.

Currently working on a GPS device

Why not build your own GPS device?

Apart from the time and effort it costs to build something [like this], the hardware is cheaper than buying a GPS device in a shop (depending on what you would want in a GPS device ofcourse).
Currently I do not plan to be able to use, read/display maps on screen, but rather work with coordinates, speed and bearing to get you where you want to be.

The components I use are: atmel atmega1284p, an oled display, serial GPS module.

I want this gps device to be:
- fast
- lower power
- simple to use

I will keep a project page here!

Windows 2008 R2 Server – Windows Update

Nice, Windows Update.

Just for your information, setting a proxy server for windows updates goes with:

netsh winhttp set proxy proxy-server:<port-nr>

Had some problems on a fresh Windows 2008 R2 server, so I deleted the whole Windows Update registry key, deleted the datastore, set the proxy and it was fixed.

Process is as follows:

(Disclaimer: you’re on your own)

net stop bits
net stop wuauserv

Delete datastore:

del %systemroot%\SoftwareDistribution\DataStore

Remove registry key (whole):


Set proxy again (in my case I used a proxy):

netsh winhttp set proxy proxy:8080

Start services again:

net start bits
net start wuauserv

Hope this helps you, good luck.

Windows, VMware virtualisation & networking hardware

When you’ve just virtualised a hardware server to a VMWare environment, and you have trouble getting networking to function again, try the following:

Log in as admin, and open cmd, enter the following commands:

set devmgr_show_nonpresent_devices=1 

Make sure you select “Show hidden devices” option in the “View” menu.

Now you go about deleting all grayed out devices. This tells the windows kernel it shouldn’t look for this hardware and certainly not try to load a driver for it.

You may, or may not need to manually specify the same IP address the server had using the netsh command, if your network services are still inaccessible, depending on your setup.

netsh interface ip set address name="Local Area Connection" static 1

Convert is cool once more

Got some PDF’s from a customer today.
I need to convert these into images, since the program I use for wifi measurement does not accept PDF’s.

Found the free solution of course, using linux.

convert -density 300 -trim test.pdf -quality 100 test.jpg

Always funny to see how … magical … the shear amount of options is for the cmd ‘convert’.

Found at

Thank you!

Timelapse picture at Ohm2013

When you make a timelapse, you take a lot of pictures, glueing that together to create a movie/film.
You can also take a few vertical lines from each picture, to create a timelapse picture :) (with the toilet rooftop being the least interesting feature though.)
Thanks Zevv, (do you have code to show?)

Preparing for ohm2013 – need I say more.

Right now i’m preparing/testing all that I promised to the people I camp with.
The end of the list is close, last shoppings will be done tomorrow.

On Tuesday we’ll move towards the holy grounds, set up a tent and possibly try to get some work done as volunteer.

In the evening a whisky-tasting event is afoot that will have to be populated, after which we can crawl to our sleeping bags to get up right in time for The Grande Opening Event.

Looking forward to it :)

In case you’re going as well, hope to see you there!

Look here for a live view at ohm2013. (has been taken offline)

Update: I hope the timelapse video’s will be online again one day at

Walking the neighborhood [NL, Doorn]

So I added a stich from a tower [Doornse Kaap] in the forest that looks out to various sites in the area, in good weather conditions you can easily spot the DOM tower of Utrecht and  the Onze Lieve Vrouwetoren in Amersfoort with the naked eye. [but not with the bad camera I used :)]

See it at the bottom of this page
