Setting Up a Name Service Policy

A name service policy is used to specify the location of system and network information managed by the Solstice AdminSuite software. This information can be located in the /etc directory for a local system, or in the NIS+ or NIS name service.

The Solstice AdminSuite software supports a mixed-mode name service policy. A mixed-mode name service policy enables you to specify different name services for configuration information. Note that this functionality is primarily useful with Host Manager.

You can use the admtblloc(1M) command to choose a mixture of name services for the Solstice AdminSuite tools to populate. For example, you can set up Host Manager to populate local /etc files for bootparams information and to populate the NIS+ tables for the other host configuration information, as shown in Figure 6-1.

Figure 6-1 Example Mixed-Mode Name Service Policy

If you choose to implement a mixed-mode name service policy, you must run the Solstice AdminSuite software from the system containing information in the /etc directory.

The admtblloc Command

The admtblloc command is used to implement a mixed-mode name service policy in Solstice AdminSuite. To use this command, you must have permission to use the software for each name service as described in "Setting Up User Permissions to Use Solstice AdminSuite".

The admtblloc command has no relation to the /etc/nsswitch.conf file used to set the system-wide name service selection policy in the Solaris 2.x operating environment. The admtblloc command is used to set the policy for all users of Solstice AdminSuite graphical user interface tools or command line interfaces.

Specifying the Name Service Policy Using admtblloc

This example shows how to specify the name service policy specified in Figure 6-1 using the admtblloc command:

$ admtblloc -c NIS+ -d solar.com bootparams NONE

In this example,

After setting the mixed-mode name service policy specified in Figure 6-1, Solstice AdminSuite will use the bootparams information stored in the /etc directory on the current host running the Solstice AdminSuitetool whenever the name service (specified in the Load window) is NIS+. The name service policy for the other configuration files (hosts, ethers, timezone and credential) is NIS+, unless you specify otherwise using admtblloc again. The mixed-mode name service policy remains in effect for all users of Solstice AdminSuite in the name service until you change it using the admtblloc command once again.

If you specify that the name service location of a configuration file is NONE using the admtblloc command, the /etc file on the current host running the Solstice AdminSuite application or command-line interface is modified. You should log in to the host where you want to use the local /etc file and perform operations using the Solstice AdminSuite on that system.

Viewing the Name Service Policy Using admtblloc

This example shows how to display the name service policy using the admtblloc command:

$ admtblloc
Name           Name Service  Path
Aliases            NIS+
Hosts              NIS+
Group              NIS+
Netgroup           NIS+
Protocols          NIS+
Bootparams         NONE
Auto.home          NIS+
RPC                NIS+
Timezone           NIS+
Netmasks           NIS+
Ethers             NIS+
Passwd             NIS+
Services           NIS+
Networks           NIS+
Locale             NIS+

In this example output,

By default, the name service policy displayed by the admtblloc command is for the name service the current host is a member of. To display the name service policy for a different name service, specify the name service context.

This example shows how to display the name service policy for the NONE or local /etc files name service context domain using the admtblloc command:

$ admtblloc -c NONE
Name           Name Service  Path
Aliases        NONE
Hosts          NONE
Group          NONE
Auto_home      NONE
Netgroup       NONE
Protocols      NONE
Bootparams     NONE
RPC            NONE
Timezone       NONE
Netmasks       NONE
Ethers         NONE
Passwd         NONE
Services       NONE
Networks       NONE
Locale         NONE

In this example,

You can also use the admtblloc command to display the name service policy for a specified configuration file. This example shows how to display the name service policy for the hosts file in the default name service:

$ admtblloc Hosts
Hosts          NIS+

The configuration file names are case-sensitive.

Configuration Files Supported by the admtblloc Command

Following is a list of the configuration files Solstice AdminSuite can use in a mixed-mode name service environment.

• Aliases
