Summary

This chapter covered the installation and configuration of NIS master servers, secondary servers, and clients. In addition to the setup of NIS itself, common "NISisms" and netgroups were discussed. The lessons learned from these sections put a powerful tool in your hands.

Some key points to remember:

• Use ypinit to set up NIS master servers and secondary servers.
• The /var/yp directory contains the makefile necessary to update NIS information.
• Consider separating NIS files from your regular system files for clarity.
• NIS servers need the ypserv daemon.
• NIS clients need the ypbind daemon.
• yppasswdd allows users on NIS clients to change their passwords.
• Schedule a reboot to test all your changes.

Although it isn't the most exciting feature to come along in recent history, NIS is one of the most useful of the core network services. In conjunction with other services, NIS gives you the ability to create a seamless system for all of your users.
