Where can I get the disk usage UI ?
I love it and I want to use it as a program.
have a look at the admin manual: http://docs.nethserver.org/projects/nethserver-devel/en/v7/duc.html
It is an opensource application that is available from https://github.com/zevv/duc
DUC website is here: http://duc.zevv.nl/
Thank you very much
The user interface for duc has been written by NethServer developers.
However, duc comes with its user interface.
