Loss off network shares on 8.2

[TheOldPresbyope]

Hi,
after sharing a remote HDD on another RPi, I want now to use it directly on moode and share it. I'm on 8.2.2 and I use Samba option.
On Linux Mint I can see 'MOODE' and 'moode' in the network tab of Nemo, but both ask me for user and password. 'pi' / 'moodeaudio' (like SSH) doesn't work... After some attempt, the network tab doesn't respond, even on the clients that usually work, or the 'windows network' item.

I interpret this to mean you've plugged a USB HDD into your 8.2.2 moOde player; you've configured the player to enable the local SMB file sharing service; and you're trying to open the resulting SMB share using the Nemo file manager app on another host running Linux Mint.

If this interpretation is correct, then I don't understand your difficulty.

I am running essentially the same setup here---just with USB thumbdrives rather than HDDs. 

I have no difficulty opening and browsing through my moOde players' SMB shares using the Caja file manager in Linux Mint (I'm running the MATE desktop rather than Cinnamon, but I believe Caja and Nemo behave the same way). When challenged, I can choose either to be a registered user and enter the moOde credentials or to be a anonymous user. Either way I can open a share, browse it, read files from it, or write files to it.

Regards,
Kent
