Configuring and Administering an NIS Slave
Server
An NIS slave server provides information to NIS clients, taking some
load off the NIS master server and substituting for the master server
when it is down. The NIS maps are created on the NIS master server and
then transferred from the master server to the slave servers. Changes to
NIS maps must be made on the NIS master server, which then pushes
the changed maps to the NIS slave servers.
An NIS slave server must also be an NIS client.
The NIS master server must be configured and running before you start
your slave servers.
This section explains how to perform the following tasks:
• To Edit the Slave Server’s passwd File
• To Edit the Slave Server’s group File
• To Enable NIS Slave Server Capability
• To Verify Your NIS Slave Server Configuration
• To Schedule Regular Map Transfers from the NIS Master Server
• To Restrict Access to the Slave Server
