NAME
      yppush - force propagation of a changed NIS map

SYNOPSIS
      /usr/sbin/yppush [ -v ] [ -d ypdomain ] mapname

DESCRIPTION
      yppush copies a new version of the NIS name service map from the master
      NIS server to the slave NIS servers.  It is normally run only on the
      master NIS server by the Makefile in /var/yp after the master databases
      are changed.  It first constructs a list of NIS server hosts by reading
      the NIS map ypservers within the ypdomain, or if the map is not set up,
      the local file is used.  Keys within the map ypservers are the ASCII
      names of the machines on which the NIS servers run.

      A transfer map request is sent to the NIS server at each host, along with
      the information needed by the transfer agent (the program that actually
      moves the map) to call back the yppush.  When the attempt has completed
      (successfully or not), and the transfer agent has sent yppush a status
      message, the results may be printed to stdout. Messages are also printed
      when a transfer is not possible; for instance when the request message is
      undeliverable, or when the timeout period on responses has expired.

      Refer to ypfiles(4) and ypserv(1M) for an overview of the NIS name
      service.

      The following options are available:

      -v              Verbose.  Print messages when each server is called, and
                      for each response.  If this flag is omitted, only error
                      messages are printed.

      -d ypdomain     Specify a ypdomain other than the default domain.
