YPPOLL(8) NetBSD System Manager's Manual YPPOLL(8)
yppoll -- ask version of NIS map from NIS server
yppoll [-T] [-h host] [-d domain] mapname
yppoll asks a NIS server process for the order number and which host is the master server for mapname. The options are as follows: -T Use TCP protocol instead of UDP for request if the -h option is present. -h host Ask the NIS server process running on host for information about mapname. If host is not specified, the server polled is the default server returned by ypwhich(1). -d domain Use the NIS domain domain instead of the default domain as returned by domainname(1).
