ypwhich(1)

NAME
     ypwhich - print the NIS server or map master hostname

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

DESCRIPTION
     ypwhich tells which network information service (NIS) server supplies NIS
     services to an NIS client, or which server is the master for a map.  If
     invoked without arguments, it prints the NIS server for the local
     machine.  If hostname is specified, that machine is queried to find out
     which NIS server it is using.

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

OPTIONS
     -d domain
             Use domain instead of the default domain.

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

     -V2     Which server is serving v.2 NIS protocol 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 then 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.

     -m mname
             Find the master NIS server for a map.  No hostname can be
             specified with -m.  mname can be a mapname, or a nickname for a
             map. If mname is not specified, ypwhich lists the names of all
             the maps and their master server.

     -t      Inhibit nickname translation.  This option is useful if there is
             a mapname identical to a nickname, which is not true of any
             IRIX-supplied map.

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