yppoll(8)
NAME
  yppoll - determine which version of a Network Information Service (NIS) map
  is at a master NIS server host.

SYNOPSIS
  yppoll [ -h host ] [ -d domain ] mapname

DESCRIPTION
  The yppoll command asks a ypserv process for the domain, order number, and
  master NIS server (also known as map parameters) associated with the named
  map.	If the server is a v.1 NIS protocol server, yppoll uses the older
  protocol to communicate with ypserv and uses the older diagnostic messages
  if a failure occurs.

FLAGS
  -h host
       Ask the ypserv process at host about the map parameters (order number
       and master server for the map).	If host is not specified, the NIS
       server for the local host is used.  That is, the default host is the
       one returned by ypwhich(1).

  -d domain
       Use domain instead of the default domain.
