 +----------------------------| Configuring nis |----------------------------+
 | Please choose the NIS "domainname" for this system. If you want this      |
 | machine to just be a client, you should enter the name of the NIS domain  |
 | you wish to join.                                                         |
 |                                                                           |
 | Alternatively, if this machine is to be a NIS server, you can either      |
 | enter a new NIS "domainname" or the name of an existing NIS domain.       |
 |                                                                           |
 | NIS domain:                                                               |
 |                                                                           |

 |                                                                           |

vi /etc/yp.conf

#
# yp.conf       Configuration file for the ypbind process. You can define
#               NIS servers manually here if they can't be found by
#               broadcasting on the local net (which is the default).
#
#               See the manual page of ypbind for the syntax of this file.
#
# IMPORTANT:    For the "ypserver", use IP addresses, or make sure that
#               the host is in /etc/hosts. This file is only interpreted
#               once, and if DNS isn't reachable yet the ypserver cannot
#               be resolved and ypbind won't ever bind to the server.
