NIS Daemons

NIS service is provided by five daemons as shown in Table 4–1. The NIS service is managed by the Service Management Facility. Administrative actions on this service, such as enabling, disabling, or restarting, can be performed by using the svcadm command. For an overview of SMF, refer to Chapter 18, Managing Services (Overview), in System Administration Guide: Basic Administration. Also refer to the svcadm(1M) and svcs(1) man pages for more details.

Note –

rpc.yppasswdd considers all shells that begin with an r to be restricted. For example, if you are in /bin/rksh, you are not allowed to change from that shell to another one. If you have a shell that begins with r but is not intended to be restricted as such, refer to Chapter 7, NIS Troubleshooting for the workaround.
