Changing the NIS domain name of this host
This section describes how to change the NIS domain name of the host. A domain
is a logical group of clients and servers. All hosts (clients and servers) within a
domain must have the same domain name.
Note: The NIS domain name should not be confused with the domain name
SMIT fastpath
The SMIT fastpath command is smit chypdom.
Removing NIS client configuration
If you no longer want to use the NIS client on the NAS Gateway 500, a NAS
administrator can remove the NIS client configuration.
SMIT fastpath
The SMIT fastpath command is smit rmyp.
Initializing the system for a NIS+ client
You initialize the NIS+ Client by any of the following ways:
Cold-start
Hostname
Broadcast
The key domain is the domain where root's credentials are stored. If you do not
specify a value, then the system default domain is used.
Use the following method to initialize a system for a NIS+ client.
SMIT fastpath
To initialize a system for a NIS+ client, use the SMIT fastpath smit nisinit.
Configuring the NAS Gateway 500 as a NIS+ client
This section describes using NIS+ as the user registry for the NAS Gateway 500.
For more information on NIS+, refer to the AIX 5L Version 5.2 Network Information
Services (NIS and NIS+) Guide.
A NAS administrator can configure the NAS Gateway 500 as a NIS+ client. Before
you configure the NIS+ client, ensure that the DES credentials have been created
for each node of your NAS Gateway 500. You must also know:

service (DNS) domain.
Using the cold-start file of another NIS+ client, preferably one from the
same domain, is the most secure method of setting up an NIS+ client
because it ensures that the client obtains its NIS+ information from a
trusted server.
Initializing by the Hostname method is more secure than the broadcast
method because it specifies the IP address of the trusted server, rather
than relying on a server to identify itself. However, if a router exists between
the client and the trusted server, it can intercept messages to the trusted IP
address and route the messages to an untrusted server.
Broadcast is the simplest but least secure method.
