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
Docking stations are quite a pleasant thing, because they save you having to plug in and out a lot of different cables (network, USB, monitors, power,…). Meanwhile, docking solutions via USB-C/Thunderbolt are also available. This means that a single USB cable is all it takes to connect the computer to the peripherals and the power supply. Practically USB-C or Thunderbolt are standards, so you can combine different devices like the HP Elite Thunderbolt Dock with a Lenovo X1 Carbon, right?
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.
How to get your mails delivered to Microsoft’s SMTP servers
When setting up a new SMTP server (i needed one for my GitLab instance), sometimes it happens that you get a new IP address which was used before for sending spam mails – or other mysterious things which might end up at the blacklist of (major) email providers – like Microsoft. So i just found this:
<firstname.lastname@example.org>: host outlook-com.olc.protection.outlook.com[184.108.40.206] said: 550 SC-001 (COL004-MC6F4) Unfortunately, messages from aa.bb.cc.dd weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. (in reply to MAIL FROM command)
So… i am my own internet provider, what now?
After some time of searching, i found a list of multiple links to the Mircosoft Delisting Service – and none of them is working, except only one. If you want to save your time when having the same problem – here it is:
After using the form, it may take some time until the request is processed. After processing you will receive a mail from Microsoft with the confirmation or rejection. If successful, it would take up to 24-48 hours to be unblocked from all relevant mail servers.
As far as i know, this applies for outlook.com, live.com and hotmail.com email addresses.
Monitor your IP’s status
Microsoft offers mail server administrators the Smart Network Data Service platform (https://postmaster.live.com/snds/), on which they can register their IP addresses and view the corresponding status, e. g. whether the IP is blocked or not. It is also worth taking a look at the Junk Mail Reporting Program to find out which mails classify users of Microsoft mail services as spam.
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.
