NIS client authentication

Question

How to configure the nis client on Ubuntu? And how to configure system authentication? There is no option for system authentication like system setting system info in my system etc.

When ever I go to software center and search them nis authentication then I have one package for nis authentication and I try to install them then one error occur that is remove hostname utility. When I try to remove hostname utility then it does not remove.

Solution

1/ Add server to /etc/hosts. This means that you can still find the server if there is a DNS failure.

2/ Install the software you need

sudo apt-get install portmap nis

You will be asked for the name of your NIS domain. Enter the name of your NIS domain. If you entered wrongly or want to change the defaultdomain of NIS change it in the file /etc/defaultdomain

robotics

For example, robotics is the name of my NIS server. Remember this parameter is case sensitive. It is probably a good idea to then add a portmap line to /etc/hosts.allow for security reasons:

portmap : <NIS server IP address>

Where "NIS server IP address" is the IP address of the NIS server.

3/ Set up name services to use NIS:

Edit /etc/passwd to add a line at the end saying:

+::::::

Edit /etc/group to add a line at the end saying:

+:::

Edit /etc/shadow to add a line at the end saying:

+::::::::

This sets up those services to include NIS entries if a match isn't found in the file. You could change other services to use NIS by using the NIS service in /etc/nsswitch.conf, but these are the important ones.

4/ Edit /etc/yp.conf and add the line:

ypserver 123.45.67.89

ypserver 987.65.43.21

Where 123.45.67.89 and 987.65.43.21 are the NIS servers.

5/ Restart NIS:

/etc/init.d/nis restart
