Solaris Advanced System Administrator's Guide, Second Edition:Setting Up the Automounter

Table of Contents

In the following example, I create an indirect automount_map named auto_local in the org_dir domain for sun.COM. We enter two rows in the table, add the indirect map to the NIS+ auto_master table, and stop and restart the automounter.

Setting Up a Direct Map

You can set up a direct map in the same way that you set up indirect maps--using the NIS+ nistbladm command. The only differences are that, by convention, the direct map is named auto_direct and you use the complete pathname in the key field. By convention, all direct mounts are included in the map named auto_direct.

See the section "Setting Up Indirect Maps" earlier in the chapter for complete instructions.

The following example sets up a direct map named auto_direct--with one entry for automounting manual pages--and adds it to the auto_master map. At the end of the example, the automounter is stopped and then restarted.

Setting Up the Master Map

When the NIS+ root master server is configured, the NIS+ auto_master map is created automatically. You do not need to create it as a separate step.

You do, however, need to provide an entry in the NIS+ auto_master map for each direct map and indirect map that you create.

The section "Setting Up Indirect Maps" contains information on how to edit the NIS+ auto_master map. That information is summarized here for your reference.

Follow these steps to add an entry to the NIS+ auto_master map:

1. Display the names of the columns in the auto_master map by typing niscat -o auto_master.org_dir.domain-name. and then pressing Return.

2. To add each entry, type nistbladm -a key=mount-pointvalue=map-name auto_master.org_dir.domain-name. and then press Return.

3. Stop and restart the automounter. (Remember that you do not need to do this for Solaris 2.3 and later releases--just run the automount command.)

Administering NIS+ Automount Maps

The following sections describe how to modify entries in existing automount maps and how to delete entries from NIS+ automount maps.

Modifying NIS+ Automount Maps

You can use the -A option for nistbladm to force an overwrite of information in an existing NIS+ automount map.

The syntax for the nistbladm -A option follows. You must specify a value for each of the columns in the table.

nistbladm -A column= ... table-name.domain-name.

For NIS+ automount tables, the more specific syntax is the following:

nistbladm -A key= value= auto_name.org_dir.domain-name.

In the next example, the administrator typed key=bin instead of key=/bin for the auto_local entry in the auto_master table. When the system booted, the automounter displayed an error message informing the administrator that the name bin in the auto_master table needed to be changed to /bin.

This is how the administrator changed the entry using the nistbladm -A command:

oak% nistbladm -A key=/bin value=auto_local auto_master.org_dir.sun.COM.
