Description:

The Network Information Service (NIS) is a system which provides
network information (login names, passwords, home directories, group
information) to all of the machines on a network. NIS can enable users
to login on any machine on the network, as long as the machine has the
NIS client programs running and the user's password is recorded in the
NIS passwd database. NIS was formerly known as Sun Yellow Pages (YP).

This package provides the NIS server, which will need to be running on
your network. NIS clients do not need to be running the server.

Install ypserv if you need an NIS server for your network. You'll also
need to install the yp-tools and ypbind packages onto any NIS client
machines.
