How to Specify Preferred-Only Servers

To specify that clients using a server list may only obtain NIS+ information from servers named in the list:

Run nisprefadm with the -o pref_only option.

#nisprefadm -L|-G -o pref_only

Where:

• -L|-G determines whether you are modifying a local or a domain-wide server list.

• -o -pref_only specifies that clients can only obtain NIS+ information from servers on the list.

This option is ignored for domains that are not served by any preferred servers.

For example, to specify in altair's local client_info file that altair must always use preferred servers and cannot use any server not on altair's preferred server list:

altair# nisprefadm -L -o pref_only
