In this exercise, you will configure an indirect map to automount the NFS share /common that is available from server20. You will install the relevant software and set up AutoFS maps to support the automatic mounting. You will observe that the specified mount point “autoindir” is created automatically under /misc. Note that /common is already mounted on the /local mount point via the fstab file and it is also configured via a direct map for automounting on /autodir. There should occur no conflict in configuration or functionality among the three. 1. Install the AutoFS software package called autofs: 2. Confirm the entry for the indirect map /misc in the /etc/auto.master file exists: 3. Edit the /etc/auto.misc file and add the mount point, NFS server, and share information to it: 4. Start the AutoFS service now and set it to autostart at system reboots: 5. Verify the operational status of the AutoFS service. Use the -l and --nopager options to show full details without piping the output to a pager program (the pg command in this case): 6. Run the ls command on the mount point /misc/autoindir and then grep for both auto.misc and autoindir on the mount command output to verify that the share is automounted and accessible: Observe the above outcomes. The mount command output illustrates the path of the AutoFS map (/etc/auto.misc), the auto-generated mount point (/misc/autoindir), file system type (autofs), and the options used during the mount process. An activity in the mount point (ls command in this case) caused AutoFS to mount the share /common on /misc/autoindir. You can use the same umbrella mount point /misc to mount additional auto-generated mount points. This mount point will automatically disappear after five minutes of idling. You can verify that by issuing the mount command again. A cd, ls, or some other activity in the mount point will bring it back. This completes the AutoFS setup for an NFS share on the client using an indirect map.
