The synced folder syncthing-osx on vm-syncthing-lin is set to Send Only.
The synced folders on the client devices are set to Recieve Only.

• What happens if nfs share disappears from /home/syncthing/syncthing-osx
  Syncthing detects this case, because the folder .stfolder is missing and stops syncing files to the clients.
  So the files on the client devices will not be deleted.

aptitude install syncthing firefox

groupadd -g 44834 sw-it
groupadd -g 46202 syncthing
adduser -uid 46202 --gid 44834 syncthing

systemctl enable syncthing@syncthing.service
systemctl start syncthing@syncthing.service

aptitude install syncthing-discosrv

systemctl enable stdiscosrv.service
systemctl start stdiscosrv.service
 

Auto generated certificate and key files:

If no certificate and key is given, stdiscosrv automatically genereate cert.pem and key.pem in /var/lib/syncthing/discosrv/

if the certificate and key under /var/lib/syncthing/disosrv changes then the DEVICE ID of the discovery server changes also
