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 hosts database (/etc/hosts and /etc/inet/ipnodes files, and NIS+ hosts and ipnodes tables). 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.
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.
The following procedure shows how to set up an NIS+ root master server:
On the root master, add the server host information into the /etc/hosts or /etc/inet/ipnodes 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
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.
