Importing SSL Certificates to Raspberry Pi Thin Client

Raspberry Pi

When playing around with the Raspberry Pi Thin Client, I ran into an issue with the SSL certificates for the Citrix Receiver client. For some reason it didn’t want to play with the certificates installed on the server side, and popped the following error message:

You have not chosen to trust “AddTrust External CA Root”, the issuer of the server’s security certificate.

Thankfully there is a quick fix for this! Since Iceweasel is also in the RPTC distribution, and it has a lot more SSL root CA certificates included by default, all that was required (in my case) was to link the certificates it has with the certificates the Citrix Receiver client can use.

Issue the following command to create symlinks for the “missing” certificates in the Citrix Receiver keystore:

1
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/

supply in the root password, which in RPTC is raspberry by default, and if your CA’s root certificate is included with Iceweasel, you should now be able to connect without getting certificate errors.

It’s pretty neat to be able to use small Raspberry Pi as a Thin Client like this, but it’s too bad that it does not support VMware Horizon View using PCoIP (yet?), only RDP, something I have yet to test since my demo environment runs PCoIP only at the moment.

Nordic VMUG Conference – My Thoughts

photo-2

On Tuesday, December 3, 2013 VMware User Group Denmark arranged the Nordic VMUG Conference. The event itself can only be described as a mini-VMworld, with over 600 registered attendees, and a speaker list worthy of such a nick-name.

The opening keynote was held by Joe Baguley, the closing keynote was held by Chad Sakac. In between those two, you had the possibility to attend sessions held by Cormac Hogan, Mike Laverick,  Frank Brix, Paudie O-Riordan, Frank Denneman, Mattias Sundling, David Davis and Duncan Epping.

There was even a mini solutions exchange where vendors scanned your badges, tried to sell you products and concepts or just update your geeky t-shirt wardrobe. Got that VMworld feeling yet?

Both Joe and Chads keynotes were eye-openers. It is really refreshing when people of “executive stature” like those two, actually skip the marketing slides and just talk. And man, both those guys talk good.

“Think more like a chicken farmer, and less like a cat owner.”

“A software defined thing that requires special hardware is not a software defined thing.”
― Joe Baguley

In particular Chad´s closing “The Nature and Impact of Disruption – On Industries, Vendors, and Customers” was really interesting as it was completely non-technical. The concept that disruption is not inherently good or bad, and that all change stems from a single individual is really intriguing. I think more people should ask themselves this; How can I, or how do I, disrupt myself?  

“Disruption is characterized by change and fear.”
― Chad Sakac

Most of the people who are a part of the VMware community has actually done this already, consciously or not. Think about that for second…

As usual at events, I spent most my time networking and talking to people, and I even got the chance to meet a few people I had yet to meet. Liselotte Foverskov and Jane Rimmer immediately springs to mind, but I also got to have a chat with Magnus Andersson and Rasmus Haslund actually drove me and my wife to the beer tasting event held at Mikkeler after the conference.

I have to say that I am very impressed by what the Danish VMUG leadership has been able to pull off here, it is no small task arranging an event of this magnitude, especially when you do it on your spare time. I am honoured to have been invited as a guest, and it serves as a real inspiration now that we are really trying to get the Norwegian VMUG active with our first meeting in Bergen in March 2014. Hopefully things are in motion, and we will have meetings in Oslo and in Trondheim as well.

There is absolutely no way we are aiming as high as VMUGDK, at least not initially, but one thing is certain; If you don’t know where you are going, any road will get you there.

Sometimes You Simply Get What You Pay For

Some time during the Podcasting for Cancer fundraiser period I somehow suggested that we should pair it with this years Movember.

Despite my wife and daughters strenuous protests, I signed up and went all in. By all in, I mean, all in. For the first time since I went to my then employers christmas party dressed as a woman, I shaved my whole face.

My trusty goatee, who had been pretty much constantly with me since 1997, was gone. I looked like I was 12 years old.

And to be honest, it went pretty much downhill from there.

I would like to thank Matthew Northam, Arjan Timmerman, Duncan Epping, Eric Sloof, Marco Broeken and Julian Wood for their Movember donations in my name.

Sorry guys, but this is what you actually paid for.  It´s not pretty, but it is what it is. Remember, you have been warned.

I guess that if this IT and virtualization thing doesn’t work out, I can always audition for a part in Sons of Anarchy…
