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 , 9comments
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:
- 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.
- Use a WebDav server like IP Tel from Avaya. However, that program looks like a Windows95 program,.. is it supported at all. ?
- 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 , 1 comment so far
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!

Binck en de ‘tussen schakel’ naar Euronext
February 10, 2011
Posted by Roel in : Life , 2comments
Dacht je ooit al is te zien dat het orderboek niet klopte of zag je rare transacties?
Vanmorgen heb ik een animatie gemaakt van een order die ik heb ingeschoten bij Binck Bank N.V. (via het ProTrader platform).
In de animatie is te zien dat er een schakel zit tussen Binck Bank N.V. en de Euronext beurs, in deze schakel wordt druk gehandeld en veel winst gemaakt met transacties die vaak nog dezelfde seconde worden uitgevoerd. Op elke transactie wordt zo een paar duizendste cent (0,001) winst gemaakt per aandeel. Dat gaat om miljoenen euro’s per maand.
Om nu juist alle schijn tegen te gaan dat klanten worden uitgebuit zou Binck Bank naast limiet, stop-los en bestens, ook ‘iceberg‘ orders moeten toestaan (juist op het ProTrader plaform), iets wat op de Euronext beurs heel normaal is. Dit wordt wellicht uit het oogpunt van winstmaximalisatie voor Binck Bank niet gedaan.
Trixbox VM on XenServer

Posted by Roel in : Technical , 10comments
I made a VM of Trixbox 2.8.0.4 for use with Citrix XenServer (5.6).
The VM is in .xva format so you can import it right away in XenServer, all yum updates are done (as of 06 dec. 2010) and latest Xen-Tools are installed.
Download it: trixbox-2.8.0.4.rar (589MB)
Details
root password: trixbox
IP: Automatic (via DHCP)
Disk: 30GB
How did I get Trixbox 2.8.0.4 working under XenServer with Xen-Tools?

Gira is threatening with letters
October 28, 2010

Childish threads about copyright on photos
Unfortunately I had to remove the photos of the Gira Homeserver 3 in the post: “Building your own Homeserver III” because Gira said it was under copyright. Gabi from Romania donated me some copyright free photos which I uploaded to the article. It’s kind of discrimiating that Gira only asks me to remove their photo’s because a Google search gives you more than 10.000 results on forums, webshops, articles and review sites (not to mention Google itself, which caches all photos, including this one).
I also had to remove the word ‘Gira’ from the title “Building your own ‘Gira’ Homeserver 3″ because Gira said you can’t build your own Gira Homeserver because only Gira makes them and if someone else makes a ‘Gira’ Homeserver it wouldn’t be a Gira Homeserver but your own Homeserver. I removed the word ‘Gira’ from the title to avoid problems, even though I have the right of press freedom (this is my blog which I use as a journalistic medium) and freedom of speech.
Intimidating letter requires delete post and sign contract
Gira also demands me to delete the whole blog post, I don’t know why. It can’t be illegal to study anything you like and write about it. I do not sell hardware or software to do illegal things (like a ‘Wii-key’ or ‘Playstation chip’) but write about stuff I’m interested in. Download their threat here.
I repeat that I don’t recommend to run Gira’s propriatary software without having a license or permission from Gira. If you want a Gira Homeserver 3, just buy it. I do not encourage anyone to do illegal things, instead I recommend being enthousiastic about the Gira products and the way they made their product.
I don’t know why Gira doesn’t like the way I’m interested in the Gira Homeserver. I really liked their design, their software.. But now I doubt about writing more enthousiastic stories.
About what should we dedicate the next article ?
Maybe I’d rather write about other, cheaper, more powerfull hardware so I don’t have to deal with intimidating letters from Gira.
What would you like to be the next article?
Did you already checked out the Gira Tastsensor 3?
While some people are stuck in the ‘tast’ age, we’re already in the ‘Touch’ scene for years now.
Look at the great and powerfull Arcus-EDS 3,5″ Touchscreen at the same price (or lower) than the aged Tastsensor 3.
Still want to have that expensive clumsy 19″ Gira brick on the wall?
What about a smooth and stylish iPad (starting at € 499,-) and throwing it at the coffee table or mount it at the wall with a nice Vogels’s clip. If you still want that brick, then buy it yourself at www.proface.nl or one of it’s resellers. Gira doesn’t make it themselves but buy them from Pro-face, see their product range here.
The closed-source (propriatary) interface, is what it’s all about.
First of all, Gira didn’t develop their interface themselves but Instaver Systems did it for them.
I heard many people jailbreaking their iPhone and downloading the Gira .ipl (App) but as I said before I don’t want to do illegal things so I’m also looking for an alternative here… (please comment about which alternative you want to know more..) (more…)
Pure water

Because i was renewing things in my home, after the electricity, it was time to do the water installation.
I decided to place a TwinTec XL2 water softener. I’m dreaming about a clear glass shower wall, a clean kettle without scale, drinking Perrier from my kitchen tap, clothes that feel softer, using less soap in my washing machine, equipment (like washing machine, kettle,..) which uses less energy and no more skin irritations.
The TwinTec XL2 removes all calcium and magnesium elements from the water. The advantage of a TwinTec XL2 above a AquaCell water softener is that it has a much higher water throughput and a separate salt resevoir.
Here you see an animation of a water softener and a movie how it works (in Dutch).

UPDATE: Photos are back online! Thanks to Gabi from Romania for the copyright free photos!
Gira has a made beautifull Homeserver and FacilityServer. Unfortunatelly it’s quite expensive (about €2400,- for their Homeserver3 and the Facilityserver is even more). Is this device made of gold ?
The opposite is true, the Homeserver 3 exists of: (more…)
Myth Busters: Benzine getankt in een Dieselauto ?
September 14, 2009
Posted by Roel in : Life , 8comments
Na 35 liter benzine in een Volvo XC90 D5 (diesel) te hebben getankt.. toch een helder moment gehad en gestopt.
Het eruit pompen is niet mogelijk omdat de tank met een soort ventiel/vacuüm zit, ook bestaan de meeste brandstoftanks tegenwoordig uit 2 kleinere tanks wat zorgt voor een beter evenwicht in de auto (ANWB monteurs noemen dit een “Vanessa” tank, inderdaad genoemd naar de voorgevel van mevr. Breukhoven). De ANWB kan de auto zelfs niet leegpompen en zal die dus gewoon bij de dealer afleveren. De dealer zal er een kleine €300,- voor rekenen. Dit hoeft echter niet! .. (more…)
