Available only on Sun 386i systems running a SunOS 4.0.x release or earlier. Not a SunOS 4.1 release feature.
ypsync gathers current Network Information Service (NIS) maps to the local NIS server. When invoked with no arguments, it polls all the NIS servers listed in the /etc/ypservers NIS map for the maps they serve, and the order of those maps. If there are any new maps that the local server does not have, or if there are maps that are more current than the local server's copy, it excutes ypxfr.8 to transfer those maps to the local server.
ypsync eliminates the need for cron.8 jobs to ensure that NIS map updates are eventually transmitted to all NIS servers, and supports different NIS maps having different masters. It is invoked periodically by ypserv.8

The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed.
