nissetup

nissetup(8)						      System Manager's Manual						       nissetup(8)

NAME

       nissetup, ypsetup - Sets up the Network Information Service (NIS) environment

SYNOPSIS

       /usr/sbin/nissetup

       /usr/sbin/ypsetup

DESCRIPTION

       The nissetup (formerly ypsetup) script configures and runs NIS on your system. You can use nissetup to initially set up your NIS configura-
       tion, to change your current NIS configuration, or to remove your NIS configuration.  NIS provides a distributed data  lookup  service  for
       sharing data among networked systems.

       Before  running	nissetup,  make sure that your system is connected to a local area network and that the network is configured and running.
       You must know the name of your NIS domain and your system's role in the domain (master server, slave server, or client).

								      Security Note

       You invoke nissetup from the SysMan Menu. See sysman(8) for more information.

       When using the nissetup script to set up a NIS server that is running with enhanced security, you must answer yes  to  the  question  about
       locking the domain name and authorized servers (the ypbind -S option). If you are setting up a master server, the server is bound to itself
       (done by default). If you are setting up a slave server, the server is bound to itself done by default) and optionally to the master server
       and any other slave servers.

       If  your  system  will  be  the master server for your NIS domain, be sure no other master exists for your domain and that the NIS database
       files are in the /var/yp/src directory.

									  Note

       Remove the root entry, if it exists, from the passwd database file.

       If your system be will be a slave server or client, be sure a master server is already set up for your NIS domain.
