NAME

       ypwhich - determine which host is the current NIS server or map master.

SYNOPSIS

       ypwhich [-d domain] [-V1] [-V2] [hostname]

       ypwhich [-d domain] [-m[mname]] [-t[mapname]]

       ypwhich -x

OPTIONS

       Identifies  which server is serving v.1 NIS protocol-speaking client processes.	Identifies which server is serving v.2 NIS protocol-speak-
       ing client processes.

	      If neither version is specified, ypwhich attempts to locate the server that supplies the current v.2 services.  If there is  no  v.2
	      server currently bound, ypwhich attempts to locate the server supplying the v.1 services. Since NIS servers and NIS clients are both
	      backward compatible, the user need seldom be concerned about which version is currently in use.  Uses domain instead of the  current
	      domain.	Finds  the  master  NIS server for a map.  No hostname can be specified with -m. The mname argument can be a mapname, or a
	      nickname for a map. When mname is omitted, ypwhich provides a list of available maps.  Inhibits nickname translation and	is  useful
	      if  there  is a mapname identical to a nickname.	Displays the map nickname table. This option lists the nicknames (mnames) that the
	      command knows of, and indicates the mapname associated with each nickname.

DESCRIPTION

       The ypwhich command identifies the Network Information Service (NIS) server that currently supplies NIS services to an NIS client.  It also
       identifies which NIS server is the master for a map.  If invoked without arguments, ypwhich returns the host name of the NIS server for the
       local machine.  If hostname is specified, ypwhich checks that machine to find out which NIS master it is using.

       Refer to ypfiles(4) and ypserv(8) for an overview of NIS.
