I finally managed to figure out how to get an SSH connection to the ClearOS 'plexserver', and ran the command you suggested.

winbind seems to be working:


The Flexshare is where you said it would be - in and my media content is within that folder, to which I'd copied it via FTP.

The Samba configuration says the share should be at

And the Plex Media Server is installed, and set up by default to allow access to media by any device on the network.

So everything so far seems to be set up.

But I still can't figure out what to do to get access to the media.

If I try in a browser , which is the usual way to access the server, I get "Connection refused".

Then, a small brainwave: try without https://, just http://

And BINGO - I have a connection, prompting me to log in to my Plex account.

So thank you everyone who's helped me get to this point.
