NIS+ Transition Guide

DNS Forwarding for NIS Clients Running under the Solaris 2 or Solaris 7 Operating Environment

If an NIS client is using the DNS forwarding capability of an NIS-compatible NIS+ server, the client's nsswitch.conf file should not have the following syntax in the hosts file:


hosts: nis dns files
Since DNS-forwarding automatically forwards host requests to DNS, this syntax causes both the NIS+ server and the name service switch to forward unsuccessful requests to the DNS servers, slowing performance.
