Setup and Configure NIS on Solaris 10

WHAT IS NIS :

     NIS is a Network Information Service consist of Server-client protocol for distributing system configuration data such as user and hostnames between computers on computer networks.

Following is the process of Configuring NIS server and NIS client

1. Setup NIS Server

2. Setup up NIS slave

3. Setup NIS client

Setup NIS Server:

First thing is to copy the NIS file to CONF file.

# cp /etc/nsswitch.nis /etc/nsswitch.conf

Select the domainname

# domainname lab.com

# domainname > /etc/defaultdomain

Domainname has been created.

# cd /etc

Following files have to be cretaed using touch

# touch ethers bootparams locale timezone netgroup netmask

Make this system as master server

# ypinit -m

Give the hostname of the system

^D

Then press y’y’ for correct

And then ‘q’ for quit

Start the NIS demons

# /usr/lib/netsvc/yp/ypstart

Now create the nis map on the server

# cd /var/yp

# /usr/ccs/bin/make

This will setup your NIS MASTER SERVER . To test it type

# ypwhich

It will display the name of the master server.

Setup NIS Slave Server

Copy nis files to conf file

# cp /etc/nsswitch.nis /etc/nsswitch.conf

Give domainname

# domainname lab.com

# domainname > /etc/defaultdomain

Make this sytem as NIS Slave server

# ypinit -s

Enter the master server host name

press y

press ^D

Start the NIS demons

# /usr/lib/netsvc/yp/ypstart

This creates the NIS SLAVE SERVER

Setup NIS Client

Copy the nis files to conf files

# cp /etc/nsswitch.nis /etc/nsswitch.conf

Give domainname

# domainname lab.com

# domainame > /etc/defaultdomain

Make the system as NIS client

#ypinit -c

Enter the master server name

Enter the slave server name

press ‘y’

press ^D

Start the NIS demons

# /usr/lib/netsvc/yp/ypstart

# ypwhich

will list the master server

Now next step is to create a user on NIS master and try to login on Client system

# useradd -d /export/home/new-user -m -s /bin/ksh new-user

# usermod -d /home/new-user

# passwd new-user

Configure user’s home directory to reside on the server for that edit /etc/dfstab file.

Edit /etc/auto_master file

Comment all line with # and change /home to /- and change -nobrowse to -browse

Also, edit /etc/auto_home file

Comment all the line and enter following things

/export/home  Master-server-ip or hostname:/export/home

save and quit

 

Update the master map

# cd /var/yp

# /usr/ccs/bin/make

Now login with the user name and password on the client system, it will login directly to the user’s home directory.
