22.2.2 Mounting an NFS File System

To mount an NFS file system on a client:

Use showmount -e to discover what file systems an NFS server exports, for example:

# showmount -e host01.mydom.com
Export list for host01.mydom.com
/var/folder 192.0.2.102
/usr/local/apps *
/var/projects/proj1 192.168.1.0/24 mgmtpc

Use the mount command to mount an exported NFS file system on an available mount point:
```
# mount -t nfs -o ro,nosuid host01.mydoc.com:/usr/local/apps /apps
```
This example mounts /usr/local/apps exported by host01.mydoc.com with read-only permissions on /apps. The nosuid option prevents remote users from gaining higher privileges by running a setuid program.
To configure the system to mount an NFS file system at boot time, add an entry for the file system to /etc/fstab, for example:
```
host01.mydoc.com:/usr/local/apps      /apps      nfs      ro,nosuid  0 0
```
