NAD810 0901 Lab 3

Objective

Centralize Local Area Network User accounts Using NIS and NFS

Preparation

• Read the Server and Client Slides
• Check/install the following rpm packages:
  • ypbind
  • ypserv
  • yp-tools
• Locate/Configure a small physical or virtaul LAN with at least 3 nodes in the LAN

Setup the NIS Server

• Backup the configuration /var/yp/Makefile to /var/yp/Makefile.org
• Modify the Makefile to support:
  • Minimum UID 5000
  • Minimum GID 5000
  • Enable slave servers
  • Merge user password and group password
  • map files for passwd, group, hosts, rpc, and services
• Set the NIS domain name (use learnid.nad810.org)
• Start the NIS server
• Initialize the map files

Setup the NIS client on the NIS server

• Edit the file /etc/yp.conf
• Add the following line:

ypserver localhost

• Start the NIS Client daemon ypbind

service ypbind start

Testing the NIS system

• use the ypcat and other yp tools from the yp-tools package
• Create a new user on the NIS server

useradd -m new-user-id
passwd new-user-id

• Update the map files

cd /var/yp
make

• use the ypcat and other yp tools to check for the new user account information

Setup the NIS client on other Linux Box on the LAN

• Set the NIS domain name to match the one on the NIS server (case sensitive)
• Edit the file /etc/yp.conf
• Add the following line:

domain [NISDOMMAIN] server [HOSTNAME]

• Start the NIS client daemon ypbind

Testing the NIS system on other Linux Box on the LAN

• Make sure that the ports used by NIS are opened on the firewalls: on NIS server and NIS client
• run the ypcat test
• Edit the /etc/nsswitch.conf file to include NIS authentication
• Try to login with the new user account created above - missing user home directory on the Linux Box!

Setup home directories for Network Users

• Enable NFS on the NIS server to export network users' home directory
• Configure NFS mount on all the systems that users will be using to login to the NIS domain
