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

Syntax
       ypwhich [-d domain] [-V1] [-V2] [hostname]
       ypwhich [-d domain] [-m mname][-t]]
       ypwhich -x

Description
       The  command  identifies the YP server that currently supplies yellow pages services to a YP client.  It also identifies which YP server is
       the master for a map.  If invoked without arguments, returns the host name of the YP server for the local machine.  If hostname	is  speci-
       fied, checks that machine to find out which YP master it is using.

       Refer to and for an overview of the yellow pages.

Options
       -V1
	  Identifies which server is serving v.1 YP protocol-speaking client processes.

       -V2
	  Identifies which server is serving v.2 YP protocol-speaking client processes.

	  If  neither  version is specified, attempts to locate the server that supplies the current v.2 services.  If there is no v.2 server cur-
	  rently bound, attempts to locate the server supplying the v.1 services.  Since YP servers and YP clients are both  backward  compatible,
	  the user need seldom be concerned about which version is currently in use.

       -d Uses domain instead of the current domain.

       -m mname
	  Finds  the  master YP server for a map.  No hostname can be specified with -m.  The mname argument can be a mapname, or a nickname for a
	  map.

       -t Inhibits nickname translation and is useful if there is a mapname identical to a nickname.

       -x Displays the map nickname table.  This option lists the nicknames (mnames) that the command knows of, and indicates the mapname  associ-
	  ated with each nickname.
