Add shared Exchange calender to Evolution Mail

Posted on by

I just spent a lot of time searching, so I really need to make sure not to forget this. I want to see a colleague’s calendar. Everything is in Office 365, so I have no problem adding the calendar in the web interface. Naive me thought, this will cause Evolution Mail to show the calendar also. Nope.

I searched for a way to add a calendar in the calendar view of Evolution. With right click on the account or in some menu. Nope. I can add calendars for myself, but not get a colleague’s calendar. Of course. That would have been too easy!

So what does work? Thank you jldugger:

On the Mail view, right click your exchange account, select “Subscribe to folder of other EWS user.” Type in the name of the account you want, and choose “Calendar” from the dropdown.

For me “Free/Busy as Calendar” worked, “Calendar” did not.

Copy your pictures from iPhone with Linux

First, you will need to install iFuse:

sudo apt install iFuse

Then, it is really simple:
1. Connect your iPhone with USB to your laptop.
2. Unlock your iPhone.
2. Run idevicepair pair.
3. The phone will ask if you want to trust this computer, say yes.
3. Open the folder Dolphin/file browser. For me, I get a “open camera” notification that leads me to the picture folder in the file browser. You can also try camera://<id given by idevicepair> or afc://<id given by idevicepair>.
4. Copy the files!

When I did this, I had to reset the connection with idevicepair a few times, but other than that it worked very well.

If this does not work for you, try this very thorough guide by Dedoimedo/Igor Ljubuncic: How to access iPhone (6s) with iOS 11 in Linux

Tree view in Nautilus on Ubuntu 18.04

Posted on by

Someone thought it a good idea to remove the settings dialogue in Nautilus. Whatever. Here is how to set “list view” as default and enable tree view:

gsettings set org.gnome.nautilus.preferences default-folder-viewer 'list-view'
gsettings set org.gnome.nautilus.list-view use-tree-view true

The REAL internet is waiting!

Did you know, that you can be connected to the internet with a cable and still be in the wrong subnet? That’s what happened to me. I plugged in the cable and the internet worked. Or so I thought. Then I needed to download a file from a company internal location and the server was unreachable. But for my colleague it worked without problems. Mhm. Typo? My colleague sent me a link – no luck. DNS? I tried the IP directly – no luck. Restart? Advice from IT – but no luck.

After involving two more colleagues, we figured it out: There is a thing called 802.1x Security Authentication. Basically, after connecting to the internet, you still need to enter your user credentials to be allowed into the internal parts of the network. In my company’s case, they use PEAP. Apparently, Windows and Mac usually ask for the authentication automatically when connecting to a network that offers this method. Hence the advice by IT to restart. Well, Linux doesn’t ask. You need to know how to answer! When you know it, it’s easy: In Gnome activate the method under “Network Settings” – “Security”. You may need a certificate – ask your admins!

I learned something new today.

Microsoft Teams on Linux

Posted on by

I use Linux in a corporate environment where Microsoft Office 365 is the toolchain of choice. One of the first things I needed to do my job was Microsoft Teams. Here are two things that worked for me.

The first (obvious) idea is to use the web UI. Messaging works out of the box with Chromium or Google Chrome. Getting audio and video calls to work is not obvious anymore. Basically, you need to pretend that you are on a Windows machine. This can be done by setting the “User Agent” to “Edge – Windows” with in the developer tools – see Christian Hujer’s blog post on the topic. Unfortunately, this hack breaks the message history. And there seems to be no way to get screen sharing to work. So while this solution is very easy, it is not optimal.

The second thing I tried and which works fine for me, is the unofficial MS Teams client by Ismael Martinez. I have it running on Ubuntu 18.04. As far as I have seen, everything works. Thank you!
