How to Initialize a New Subdomain Client Machine

  • Type the following command as superuser to initialize the new client on the new client machine.

subclient1# nisclient -i -d sales.doc.com. -h client2
Initializing client subclient1 for domain "sales.doc.com.".
Once initialization is done, you will need to reboot your machine.
Do you want to continue? (type 'Y' to continue, 'N' to exit this script)

The -i option initializes a client. The -d option specifies the new NIS+ domain name. (If the domain name is not specified, the default becomes the current domain name.) The -h option specifies the NIS+ server's host name.

See "How to Initialize a New Client Machine" for the rest of this script's output.

Initializing Subdomain NIS+ Client Users

You use the same procedure (nisclient) to initialize a user in the new domain as you do to initialize a user in the root domain. All users must make themselves NIS+ clients. This example shows you only what you would type to initialize a user for the new domain. For the rest of the script's output, see "How to Initialize an NIS+ User".

Prerequisites to Running nisclient

Before you can use the nisclient script to initialize a user:

  • The domain must have already been configured and its master server must be running.

  • The master server of the domain's tables must be populated. (At a minimum, the hosts table must have an entry for the new client machine.)

  • You must have initialized a client machine in the domain.

  • You must be logged in as a user on the client machine. In this example, the user is named user2.

Information You Need

You need:

  • The user's login name (user2, in this example)

  • The default Secure RPC password (nisplus)

  • The login password of the user that will become the NIS+ client

How to Initialize an NIS+ Subdomain User

  • To become an NIS+ client, type the following command while logged in as the user.

user2prompt% nisclient -u
At the prompt below, type the network password (also known as the 
Secure-RPC password) that you obtained either from your administrator 
or from running the nispopulate script.
Please enter the Secure-RPC password for user2:

See "How to Initialize an NIS+ User" for the rest of this script's output.

Summary of Commands for the Sample NIS+ Namespace

Table 4-4 summarizes the actual commands that you typed to create the sample namespace. The prompt preceding each command indicates on which machine the command should be typed.
