Setting up NFS for file sharing

Proven on:

11 (bullseye)

Install NFS Server

• sudo apt install nfs-kernel-server

Configure NFS Server

• sudo vi /etc/exports

Add/edit:

/path/to/be/shared *(rw,async,no_root_squash,no_subtree_check)

For the changes to take effect, export and start NFS service.

• sudo exportfs -a
• sudo /etc/init.d/nfs-kernel-server start

Pretty simple...

Connecting to the NFS Server

You'll need NFS installed

• sudo apt install nfs-common

or

• sudo apt install nfs-kernel-server

Then you can check what's shared from any particular machine:

• showmount -e [ServerName or Address]
  • (requires sudo on Debian...)

will show you what's shared from a machine

Setting up & mounting a share

• sudo mkdir -p /path/to/mount/share
• sudo mount [ServerName or Address]:/path/to/be/shared /path/to/mount/share

Better yet tho...

• sudo vi /etc/fstab

& add an entry:

[ServerName or Address]:/path/to/be/shared /path/to/mount/share nfs rw,user,exec 0 0

TBD

• Learn what flags do what in /etc/exports
• Browsing in the GUI would be nice...
• Look into automounting (including graceful failure modes)
