How to Set Up a Multihomed NIS+ Root Master Server

The procedure for setting up a multihomed NIS+ server is the same as setting up a single interface server. The only difference is that there are more interfaces that need to be defined in the local /etc/hosts file and the NIS+ hosts table. Once the host information is defined, use the nisclient and nisserver scripts to set up the multihomed NIS+ server. For information about setting up a multihomed replica server, see "How to Set Up Multihomed NIS+ Replica Servers"

Caution -

When setting up a multihomed NIS+ server, the server's primary name must be the same as the nodename for the system. This is a requirement of both Secured RPC and nisclient.

• Secured RPC relies on the nodename to create the netname for authentication.

• nisclient relies on the primary name to create the credential for the client.

If these names are different, Secure RPC authentication will fail to work properly causing NIS+ problems.

The following procedure shows how to set up a NIS+ root master server:

1. On the root master, add the server host information into the /etc/hosts file. For example, the /etc/hosts file for the hostA system with three ethernet interfaces looks like:

   127.0.0.1 localhost loghost 192.168.10.x hostA hostA-10 hostA-le0 192.168.11.y hostA hostA-11 hostA-le1 192.168.12.z hostA hostA-12

2. Set up the server as a multihome NIS+ root server with nisserver.

   hostA# nisserver -r -d sun.com

   where our example shows sun.com as the root domain name. Issue the nisserver command using the name of your root domain name

After completing the steps for setting up a multihome NIS+ root server, the remainder of the setup is exactly the same as for a single interface server.
