SSH connection is exclusively dedicated for the developer’s access to Volumio OS via command-line. It is disabled as default (recommended for security reasons). Enable it only if required, for remote support or for saving a log link.
TO ENABLE SSH:
Find the SSH section, and click 'enable'. From now on your SSH will be permanently enabled. To disable SSH again, click 'disable'.
