[SOLVED] Mount NFS without permission to read

[matzemedia]

I'am new at moodeaudio and try to mount a external music source. I tried today several "Mount flags" but still get the problem that the mounted files are not readable.

Code:

drwxrwxrwx 2 root root        0 Feb 14 17:19  .
drwxrwxrwx 2 root root        0 Feb 14 17:19  ..
-rwxrwxrwx 1 root root        4 Feb 14 17:19  test.txt
pi@moode:~ $ vi /mnt/NAS/m4chine/2Raumwohnung/test.txt
pi@moode:~ $ less /mnt/NAS/m4chine/2Raumwohnung/test.txt
/mnt/NAS/m4chine/2Raumwohnung/test.txt: Stale file handle

Same when opening a file with vi: Permission Denied

Code:

pi@moode:~ $ less /mnt/NAS/m4chine/2Raumwohnung/test.txt

I use moodeaudio 7.01
The external Server is a NAS, I've mounted without any problem with OSX, volumio,...

I tried to mount the external library although by using mount:

Code:

sudo umount /mnt/NAS/m4chine
sudo mount -t cifs -o username=username,ro,dir_mode=0777,file_mode=0777 //192.168.1.50/m4chine/EXTERNAL/test /mnt/NAS/m4chine

Same problem!

Any idea?
