New page

NIS or Network Information Services is a simple - and insecure - way of making [[SSO|Single Sign On]] in a cluster of UNIX/Linux machines. Very useful in a closed network.

Originally NIS was called YP - Yellow Pages - and the acronyms YP and NIS are used.

There are up to three roles in a NIS installation
;Master server:The master server - shares files to slaves and clients. For example the passwd and group file
;Slave server(s):Maintain copies of the Master Server shared files. Provides redundancy and load balancing
;Clients:Use the shared files - for example for single sign on. Users added on the master server
=Installation of the master server=
Add the following line to '''/etc/hosts.allow'''. (In this case master,slaves and clients lives in the 10.222.0.0/24 network)
<source lang=cli>
portmap ypserv ypbind: 10.222.0.0/255.255.255.0
</source>
Install NIS. You will be asked to enter the domain name. The domain name is not the DNS domain name - but a unique name for the the cluster of machines sharing the same information. (I use the DNS domain name - one less thing to remember)
<source lang=cli>
apt-get install portmap nis
</source>
*Edit '''/etc/default/portmap''' and comment out the '''ARGS="-i 127.0.0.1"''' line
*Edit '''/etc/default/nis''' and set the NISSERVER line to NISSERVER = master
*Edit '''/etc/yp.conf''' and add a server line of the form: (Note my domain-name is '''c1.local''')
<source lang=cli>
domain c1.local server 127.0.0.1
</source>
*Edit '''/etc/ypserv.securenets''' remove the '''0.0.0.0''' line - insecure - and add your net/nets

 When adding a user with '''adduser''' it's necessary to rebuild the NIS maps
