Configuration file: /etc/exports[edit]

/etc/exports [3]

Example:

/export       192.168.1.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/users 192.168.1.0/24(rw,nohide,insecure,no_subtree_check,async)
fsid=0 signals the NFS server that this export is the root.

Warning: /etc/exports is affected by adding additional space characters, be mindful about format

NFSv4[edit]

NFSv4 no longer utilizes the MOUNT protocol.
