Basics of NIS Management
- Built on the client-server model.
- An NIS server is a machine that contains NIS data files called maps.
- Clients are hosts that request information from these maps.
- Servers can be divided into master and slave servers. Slave
servers handle request from the clients but they do not modify the NIS
maps.
- Example : How can you distribute the information in /ect/hosts
file using NIS ?
- /etc/hosts tells the system how to convert host names to IP addresses.
- When a client needs to look up the internet address of some system, it
would normally read the local /etc/hosts file.
- When NIS is running, the client bypasses its hosts file, and asks the
NIS server for the information.
- What are NIS Domains ?
- A domain is a set of NIS maps.
- The group of systems that share a set of NIS maps are grouped under
the same domain.
