Before you can use the nisclient script:
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 or ipnodes table must have an entry for the new client machine.)
You must be logged in as superuser on the machine that is to become an NIS+ client. In this example, the new client machine is named client1.
You need:
The domain name.
The default Secure RPC password (nisplus).
The root password of the machine that will become the client.
The IP address of the NIS+ server (in the client's home domain).
If DES authentication is used, note the Diffie-Hellman key length used on the master server. Use nisauthconf to ascertain the master server Diffie-Hellman key length.
