29.3.2. Configuring the Client
To enable NFS clients, set this option in each client's /etc/rc.conf:
nfs_client_enable="YES"
Then, run this command on each NFS client:
# service nfsclient start
The client now has everything it needs to mount a remote file system. In these examples, the server's name is server and the client's name is client. To mount /home on server to the /mnt mount point on client:
# mount server:/home /mnt
The files and directories in /home will now be available on client, in the /mnt directory.
To mount a remote file system each time the client boots, add it to /etc/fstab:
server:/home /mnt nfs rw 0 0
Refer to fstab(5) for a description of all available options.
Вот как тут понять, где авторизация на НФС шару... Или надо делать её открытой, заходи кто хочет?
