Some Troubleshooting Tips

If the NIS software isn't behaving as you think it should, you can check a few things:

• Make sure the processes are running. Use ps auxw to list all the running processes. Make sure you see the appropriate processes running, regardless of whether the machine is a client, a server, or both.
• Check system logs (in /var/log) to see if there are any messages indicating peripheral problems that could be affecting your configuration.
• If the processes appear to be running but are not responsive, kill them and restart them. In some rare circumstances, the daemon may be misbehaving and may need to be restarted.
• Make sure /etc/nsswitch.conf is configured properly. This is a common problem.
• If you are trying to start the daemons by hand, make sure you are logged in as root.

When encountering problems, slow down, take a short break, and then retrace your steps. It's amazing how often simply slowing down helps you find problems.
