It has a NAS server.
It should be possible to mount it with a fstab-entry like this:
//192.168.8.199/openshare/muziek /media/muziek cifs guest,uid=1000,iocharset=utf8,codepage=unicode,unicode 0 0
Have you tried the above?
Is that the correct IP address for the device?
It would be unusual for PCLOS to have a UUID of 1,000 ...... ours usually start at 500.
Make sure you have the CIFS package installed via Synaptic.
You could then look to adding codes to the line to see if it will automount and allow read & write permissions ......... auto, rw for instance.
It seems the above is limiting access to Guest with a UID of 1,000
...... but I am not familiar with this so may be incorrect ....
