YPWHICH(1)							    YPWHICH(1)

NAME
       ypwhich - which host is the YP server or map master?

SYNOPSIS
       ypwhich [ -d [ domain ] ] [ -V1 | -V2 ] [ hostname ]
       ypwhich [ -t mapname ] [ -d domain ] -m [ mname ]
       ypwhich -x

DESCRIPTION
       ypwhich	tells  which  YP server supplies yellow pages services to a YP
       client, or  which  is  the  master  for	a  map.	  If  invoked  without
       arguments,  it  gives the YP server for the local machine.  If hostname
       is specified, that machine is queried to find out which YP master it is
       using.

       Refer to ypfiles(5) and ypserv(8) for an overview of the yellow pages.

OPTIONS
       -d      Use domain instead of the default domain.

       -V1     Which   server  is  serving  v.1	 YP  protocol-speaking	client
	       processes?

       -V2     Which server is serving v.2 YP protocol client processes?

	       If neither version is specified, ypwhich attempts  attempts  to
	       locate the server that supplies the (current) v.2 services.  If
	       there is no v.2 server currently bound, ypwhich	then  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.

       -t mapname
	       Inhibit nickname translation; useful  if	 there	is  a  mapname
	       identical to a nickname.

       -m      Find  the  master  YP  server  for  a  map.  No hostname can be
	       specified with -m.  mname can be a mapname, or a nickname for a
	       map.  When mname is omitted, produce a list available maps.

       -x      Display	the  map  nickname  table.   This  lists the nicknames
	       (mnames) the  command  knows  of,  and  indicates  the  mapname
	       associated with each nickname.
