Cannot write to Qnap shared folder

[thelastreso]

I like to copy data from a Ubuntu 16.04 Server to a shared folder on my Qnap TS-251 (FW 4.2.2, Raid 1). I have read access to the folder but I can't write on it.
On Ubuntu the etc/fstab looks like this:

//192.168.0.102/backup /mnt/qnap cifs defaults,username=ben,password=foobar,uid=501,gid=100

On the Qnap I added the user "ben" with R,W,X.

Has anybody an idea what else to do to get write access on the shared folder?

Thanks, Thomas

Thomas,

Start with a manual CIFS mount from the shell using minimum of options - just username and password.

Double check the Ubuntu user has the access required on the mount point /mnt/qnap .
