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
Completing the Lab
