Chapter 4. System Management Using NIS
We’ve seen how NIS operates on master servers, slave servers, and clients, and how clients get map information from the servers. Just knowing how NIS works, however, does not lead to its efficient use. NIS servers must be configured so that map information remains consistent on all servers, and the number of servers and the load on each server should be evaluated so that there is not a user-noticeable penalty for referring to the NIS maps.
Ideally, NIS streamlines system administration tasks by allowing you to update configuration files on many machines by making changes on a single host. When designing a network to use NIS, you must ensure that its performance cost, measured by all users doing “normal” activities, does not exceed its advantages. This chapter explains how to design an NIS network, update and distribute NIS map data, manage multiple NIS domains, and integrate NIS hostname services with the Domain Name Service.
NIS network design
At this point, you should be able to set up NIS on master and slave servers and have a good understanding of how map changes are propagated from master to slave servers. Before creating a new NIS network, you should think about the number of domains and servers you will need. NIS network design entails deciding the number of domains, the number of servers for each domain, and the domain names. Once the framework has been established, installation and ongoing maintenance of the NIS servers is fairly straightforward. ...
