Can't mount CentOS NFS share on Windows 10 - "Network Error - 53"

Solution 1:

On the Linux part - make sure your NFS Server Configuration is correct:

• nfs-utils and nfs-utils-lib should be installed

• rpcbind, nfs-server, nfs-lock, nfs-idmap should be enabled

• rpcbind, nfs-server, nfs-lock, nfs-idmap should be started

• Choose the directories you want to share

• make sure your user can access everything inside his directory

• get the UID and GID of the user you plan to use

• get the IP address of your Windows 10 NFS client

• edit the exports file (etc/exports) and add the user you will use to it: /home/user 192.168.1.2(rw,sync,root_squash,all_squash,anonuid=1001,anongid=1001) - note: the IDs are the ones obtained previously

• restart the service with systemctl restart nfs-server

• get the proper ports with rpcinfo -p

• add them to the firewall

On the windows part:

• make sure you installed Client for NFS

• you now need to match the UID and GID that pulled earlier (1001 in the linux part example) on both the Server and the Client

• regedit to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default

• You will need to make two new DWORD (32-bit) entries by right clicking inside the Default key. They should be named “AnonymousGid” and “AnonymousUid”. They should both have a decimal value matching your user’s GID and UID that you got earlier (1001 in the example)

• restart NFS service on the Windows 10 Client side by using :

  nfsadmin client HOSTNAME config casesensitive=yes

  nfsadmin client HOSTNAME stop

  nfsadmin client HOSTNAME start

• finally, make your mount: mount -o anon \\192.168.1.3\home\storage\ X:

You should get a successful mount message.

Solution 2:

This solved it for me:

The NFS was running only under NFS v4 - adding v2/3 service to the Linux server solved the problem and I could mount the NFS.

Solution 3:

In my case the firewall was causing this even though I had the ports 111, 2049 and 20048 allowed through. I just opened up the firewall completely between the two servers and it worked so I'm not sure which ports need to be opened.

I suspect following this advice to set static ports and then opening those up would also work: https://askubuntu.com/questions/1313682/set-static-ports-for-nfs-v3-on-ubuntu-20-x-server
