ypwhich(1)                     DG/UX R4.11MU04                    ypwhich(1)


NAME
       ypwhich - tell which host is the NIS server or map master

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

DESCRIPTION
       Ypwhich tells which NIS server supplies the Network Information
       Service to an NIS client, or which is the master for a map.  If
       invoked without arguments, it gives 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 the Network
       Information Service.

OPTIONS
       -d     Use domain instead of the default domain.

       -V1    Tell which server is serving v.1 NIS protocol client
              processes.

       -V2    Tell 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.

       -t mapname
              Inhibit nickname translation; useful if there is a mapname
              identical to a nickname.  This is not true of any DG/UX
              ONC/NFS-supplied map.

       -m     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.  When mname is omitted, produce a list of 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.
