I am on ethernet and all other debian machines in the subnet are doing 
excellent. syslog was an excellent idea, indeed there are many suspicious 
entries:

look really strange.

That interface is managed by network-manager .... I am wondering if I should 
fall back to /etc/network/interfaces ...

For network-manager I do not have experience on headless system, tried this 
here to get information (is the systemd-networkd not running expected?)

root at master:~# networkctl --all
WARNING: systemd-networkd is not running, output will be incomplete.

  2 eno1             ether              n/a         unmanaged 

2 links listed.

Any idea why IPv6 is not properly working is welcome.


Thanks
Rainer
