Managing NIS Services

Context

Network Information Service (NIS) is a directory service technology that centrally controls the system management database. NIS addresses this challenge by providing the network information for all hosts in a LAN. Specifically, when a user's user name and password are stored in the NIS password database, this user can log in to any computers running the NIS client software. In addition, you can centrally manage the complete network information of the LAN simply by maintaining the databases on the NIS server.
