System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP)

Preparing a Slave Server

Before actually running ypinit to create the slave servers, you should run the domainname command on each NIS slave to make sure the domain name is consistent with the master server.

Note –

Domain names are case-sensitive.

Make sure that the network is working properly before you configure an NIS slave server. In particular, check to be sure you can use rcp to send files from the master NIS server to NIS slaves.
