Liam & Carson,

Thanks for the elaborate reply. To clarify: ssh & X didn't come to Linux 
but to Unix (as Carson said in his opening sentence) an sure security 
was not an issue in those days. I come from Unix (starting with Bell 
Unix in 1980 (!) and working in the 90ies with IRIX (Silicon Graphics 
Unix) and on - for us simple - Intel processors with Linux until today. 
In the 80ies we used Unix sparsely as most programs were developed on 
DOS, never touched MS WIndows, so Iḿ reasonably familiar with Unix/Linux.
I installed and upgraded ubuntu on this system using the factory 
provided images. I didn't build the Linux myself. Of course on the 
system Xserver is running and when I looked yes xfce4 is running but I 
cannot find which desktop manager is running.
My workstation is a AMD 6300 6-core running 3000MHz 8Gb memory self build.
The controlled system is an Odroid-C2 ARM 4-core 2Gb memory and the 
beauty is that it uses <5W and is very low cost (even cheaper than the 
raspberry). I have it a few weeks and am experimenting with it to use it 
as a standalone server.
More information is here http://www.hardkernel.com/main/main.php.
My mystery with vnc is still not solved.
