Setting up a NIS slave server

This note explains how to setup a nis slave server. It is assumed that you have a NIS server running .

  Setup
       Existing NIS server  named  mahalanobis  on 10.107.35.1
       The slave  server is to be set up  is named  gauss on 10.107.35.6

Install ubuntu 10. 04 Lucid on  gauss  10.107.35.6. Setup the network interface and make sure that it works as a standalone machine.


Install NIS software on Gauss

 # apt-get install   portmap nis

Setup the slave as a NIS client

 Edit /etc/yp.conf  and add

ypserver 127.0.0.1
Edit  /etc/hosts on master ( Mahalanobis) and add an entry for slave 
 
10.107.35.6    gauss
Edit  /etc/hosts on  slave ( Gauss) and add an entry for master 
10.107.35.6     mahalanobis

 
Log on to the master server. Add the slave server to the master 
server's database map by editing the /var/yp/ypservers file on the 
master.
 # File: /var/yp/ypservers
mahalanobis
  gauss
 
The make file in the /var/yp directory defines how the NIS server will 
build the database map and how the master will relate to the NIS slave. 
Edit the make file to allow the master to push maps to the slave.


# File: /var/vp/Makefile
 
# Allow the master to do database pushes to the slave
#
NOPUSH=false

Run make command. (You must be in /var/yp )

Iniitialise slave database 
#  /usr/lib/yp/ypinit -s  mahalanobis

On   slave ( gauss) edit /etc/defaults/nis ) Change  the flag NISSERVER to slave

  # /etc/defaults/nis    Configuration settings for the NIS daemons.
#

# Are we a NIS server and if so what kind (values: false, slave, master)?
NISSERVER=slave


Restart   nis services on  slave

  #/etc/init.d/nis restart


Testing

   On a client machine which is being authenticated by the master edit /etc/yp.conf  and change the  ypserv  entry to point to the new slave machine.
Restart nis on that client machine and see if you are able to login.
