Examples of NFS Mounts
• Mounting a directory as read-only with no set userid privileges
mount -r -o nosuid broccoli:/usr/share/man /usr/share/man
In this example, the NFS clients mount the /usr/share/man directory from the NFS server
broccoli. The local mount-point is also /usr/share/man. The directory is mounted as
read-only.
Figure 4 illustrates this example.

• Mounting a Home directory
mount -r -o nosuid broccoli:/home/broccoli /home/broccoli
mount -r -o nosuid cauliflower:/home/cauliflower /home/cauliflower
In this example, the NFS client mounts the home directories from NFS servers broccoli and
cauliflower . The nosuid option prevents programs with setuid permission from executing
on the local client.
Figure 5 illustrates this example.

• Mounting an NFS Version 2 filesystem using the UDP Transport
mount -o vers=2,proto=udp onc21:/var/mail /var/mail
In this example, the NFS client mounts the /var/mail directory from the NFS server, onc21,
using NFSv2 and the UDP protocol.
• Mounting an NFS filesystem using an NFS URL
mount nfs://onc31/Casey/mail /Casey/mail
In this example, the NFS client mounts the /Casey/mail directory from NFS server, onc31,
using the WebNFS protocol.
• Mounting an NFS filesystem by using a public file handle
