The RUTX-unit is installed in my Motorhome and that is stored away during the week.
The AppleTV is currently not powered up and the WiFi is set to TKIP right now because that is what works.
I was still able to do a quick SSH from my mobile phone outside the garage and the result is below.
Once I have full access again I can switch to AES and re-do the SSH command when the AppleTV is running.
Sorry, no external logging is set up.
