Setup cluster NIS Client

There are some good manuals around, but the key thing is

1. when installing via apt-get make sure to specify the domain name of the NIS master
   1. If things don’t work well, use apt-get purge nis to remove and reinstall nis to setup your nis domain.
2. setup the ypserver in /etc/yp.conf
   1. ypserver [full address]
3. add nis to the appropriate lines in /etc/nsswitch.conf
   1. passwd, group, shadow, hosts
4. Finally use the yptest to check if things are working.
5. Xenial has an issue where the rpcbind service does not start up properly. I used the following command to set rpcbind to start at bootup.
   1. 1. # systemctl add-wants multi-user.target rpcbind.service
      2. This solution was found on askubuntu

In our setup, make sure not to add the kaist.ac.kr suffix!!

Step is:

1. apt install nis
2. check with yptest
3. If it works, open /etc/nsswitch.conf and add nis to the end of passwd group shadow and hosts
4. if you’re on Xenial (16.04) follow step 5 above.
