I would like to mount my qnap to my Linux Mint laptop. The IP address of the NAS is : 192.168.0.25

So I executed this command:

sudo mount -t nfs -o username=user_name,password=my_password 192.168.0.25:HR /mnt/qnap

I had this error:

mount.nfs: an incorrect mount option was specified

When I use the UI and click on Network then MyNas icon, I had this error:

Failed to retrieve share list from server: Connection refused

Do you see any solution ?

== Update ==

This is the showmount command output:

showmount -e 192.168.0.25

Export list for 192.168.0.25:
/homes       
/my_home       
/Web         
/Public      
/OceanKTV    
/Multimedia  
/Download    
/Container

There is neither a username nor a password option for NFS mounts. A typical NFS mount command looks like as follows.

sudo mount -t nfs 192.168.0.25:/Multimedia /mnt

For further mount options you can refer to the manpage of NFS.

  • why shouldn't I put a login/password ? How can I authenticate then ? I found this in https://wiki.qnap.com/wiki/Mounting_an_NFS_share_on_Ubuntu – 4m1nh4j1 Apr 27 '17 at 10:06
  • Because NFS does not work that way. Unless you have NFSv4, there is no user authentication. With NFSv4, the only way for authentication is kerberos, which does not need username/password but works with "tickets". In NFSv3 and below, you only can allow/disallow a network segment or single hosts or netgroups. – Thomas Apr 27 '17 at 12:11
