I have My cloud DL 2100. Firmware 2.11.140.
I need to configure samba for logging all user actions when you access folders and files (delete, edit, add, etc.). Is it possible to do?
It is possible via SSH. However, such proceedings are not warranted or supported by Western Digital.
From my experience I had to turn on Extended logging in the web interface.
Settings -> Utilities -> Enable “Extended Logging”
