How to allow rw NFS share in a heterogeneous environment (GNU/Linux, Windows)

  • 772

I have a NFS server on Ubuntu 20.04. My /etc/exports looks like

/home/user2 10.4.200.2(rw,sync)
/home/user3 10.4.200.3(rw,sync)

On a Windows 10, I mount the folder using "Connect a network storage" (Sorry, it might not be an accurate translation because the system language is not English). I enter in the folder field

IP_of_the_server:/home/user2

However, the remote NFS storage appears in read-only mode. Indeed, I cannot create nor delete files.

  1. I added two keys in Windows registry in order to make the mapping.

    1. Open regedit by typing it in the search box end pressing Enter.
    2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default.
    3. Create a new New DWORD (32-bit) Value inside the Default folder named AnonymousUid and assign the UID found on the UNIX directory as shared by the NFS system.
    4. Create a new New DWORD (32-bit) Value inside the Default folder named AnonymousGid and assign the GID found on the UNIX directory as shared by the NFS system. Windows 10: Regedit NFS AnonymousUid and AnonymousGid
    5. Restart the NFS client or reboot the machine to apply the changes.
