You need to configure the NIS domain using your domain name (such as mydomain.test). And after clicking on the NIS Server icon, you must choose the NIS tables to serve. For our example, we will select the files passwd, group and shadow (you use the Ctrl key to select several files in the list).

Figure 8.1. NIS Server

You do not need to modify the file description done in the Master NIS files section. In the NIS menu, the NIS Tables icon allows to modify the tables that are served. The Server Security icon allows to select the clients you want to serve, or not.

For each client, you have to configure the NIS domain name parameter with the domain name used by the server. You must also enter IP address.

That's all.
