In How to set up your YubiKey NEO I already mentioned that you can also use your YubiKey as SSH key. In GPG Agent Forwarding I show how to forward your GPG agent to remote machines for decryption/signing. What’s missing is a tutorial on how to make it all work together, how to use your GPG Agent for SSH in Gnome. Read More
Introducing DigitalOcean Spaces
DigitalOcean Spaces is a new product from DigitalOcean, which offers a S3 compatible, flexible storage place for your data – and it’s much simpler to configure compared to Amazon’s S3 or other solutions i know.
Because uploading the whole stuff via a web based interfaces is really annoying, i tried to mount the storage with my Ubuntu Linux. Here’s the result, which may help you to success faster than i did.
Recently, i bought a YubiKey NEO (affliate link) with the goal to improve the security and comfort using platforms like GitHub, GitLab – or other tools working with GPG encryption etc. Here i will show you the steps for getting your YubiKey NEO running with your Linux (in my case Ubuntu) system.

How to set up Canon MG5350 with Ubuntu
Now that I was repeatedly faced with the same problem to set up my printer (Canon MG5350) under Ubuntu. So i decided to write a small documentation which steps are necessary for the successful operation. The instructions refer specifically to my printer, but in my experience all models of Canon can be set up in a similar way.
Terrifying. With every Ubuntu installation I have been able to convince my window buttons to take the position on the right side of the screen via my instructions from here. Now, after an upgrade from Ubuntu 12.04 to Ubuntu 12.10, they were left again. Stupid thing: The old manual doesn’t work anymore!
For all frustrated users, here’s the command to straighten them out:
gsettings set org.gnome.desktop.wm.preferences button-layout ‘:minimize,maximize,close’
As far as new Ubuntu versions are concerned, I am a very brave person. Therefore, a few days ago I updated my netbook to the Alpha6 of the new Ubuntu Lucid. The first impression was very positive after the reboot was completed, but the only negative aspect that came into play was probably the only one, but it was very annoying: The artwork team decided to display the buttons for minimizing, maximizing and closing on the left side of the windows by default. For someone who has always been used to finding these buttons on the right since he started using his PC, this is an unpleasant experience. Again and again, the mouse moves up to the right – to click into the void.
So I started looking for ways to move these buttons to the right again. Here is the solution how it works:
In the gconf-editor tool, there is a key with the name button_layout in the category /apps/metacity/general. The value of this is set to maximize, minimize, close:. By adjusting this value you can influence the position of the variant I am using: minimize, maximize, close, but everybody can decide for himself. Click on each window again, then all the new settings should have been applied.
I had this problem once again, but the instructions don’t work anymore. For a new tutorial see here.
To support the computer monitoring at the University of Trier, a Nagios system was set up, which tests the function of important systems at regular intervals and notifies the administrators of problems if necessary. However, there was initially only email notification, so that the problem report was sometimes seen very late, which in exceptional cases may cause further problems. That’s why we wanted to implement a faster notification, in this case via an SMS Gateway. Read More
