Once both client and server are set up correctly (and assuming that the NFS server is configured to allow connections from the client), you can go ahead and mount an exported NFS filesystem on the client. In this example, inventor is the NFS server and sidekick (IP address 192.168.1.9) is the NFS client. Inventor's /etc/exports file contains a line that looks like this, allowing connections from any machine on the 192.168.1 network:

/ 192.168.1.1/24(rw,no_root_squash)

Now, logged into sidekick as root, we can type:

# mount inventor:/ /mnt/nfs

Inventor's root filesystem will now be mounted on sidekick at /mnt/nfs; you should now be able to type cd /mnt/nfs and look around inside and see inventor's files. Again, note that if inventor's /home tree is on another filesystem, then /mnt/nfs/home will not contain anything -- another mount (as well as another entry in inventor's /etc/exports file) will be required to access that data.
