No permission to read from NFS as user

Post by msssm » Wed Mar 17, 2021 4:42 pm

Version: 4.2.6


I can mount the NFS share from my Linux, but have no permission as user.

I created a user msm, permission for share /Download is RW, applied to all subfolders.
User and group permission for Download is Read/Write for users "admin" and "msm".
NFS-Settings are ALLS_QUASH to UID of msm. Allowed IPs are *.

/etc/exports is now:

Code: Select all

[~] # cat /etc/exports 
"/share/HDA_DATA/Download" *(rw,async,no_subtree_check,insecure,all_squash,anonuid=500,anongid=100)

[~] # ls -al /share/HDA_DATA/Download
drwxrwxrwx    3 admin    administ      4096 Mar 16 10:32 ./
drwxrwxrwx   32 admin    administ      4096 Dec  1 14:36 ../
drwxrwx---    2 admin    administ      4096 Jan 23  2018 @Recycle/
-rwxrwx---    1 admin    administ 3268147200 Nov 28  2015 backup.iso*

[~] # grep msm /etc/passwd 
msm:x:500:100:Linux User,,,:/share/homes/msm:/bin/sh

[~] # grep msm /etc/group  
From filesystem view, the user msm has no permission as it is no member of group admin. I also tried to add the user to the admin group, but this did not solve it either.

On the Linux client it looks like:

Code: Select all

$ ls -al /mnt/lan/Download/
total 5641828
drwxrwxrwx 3 root root       4096 16. Mär 10:32 .
drwxr-xr-x 9 root root          0 17. Mär 07:12 ..
-rwxrwx--- 1 root root 3268147200 28. Nov 2015  backup.iso

$ mount |grep Download
nas:/Download on /mnt/autofs/lan/Download type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=,mountvers=3,mountport=30000,mountproto=udp,local_lock=none,addr=

$ md5sum /mnt/lan/Download/backup.iso
md5sum: /mnt/lan/Download/backup.iso: Permission denied
Before messing around on the terminal, how would I solve this from the QNAP gui?
