 Name

    ypwhich - which host is the network information service (NIS) server or
    map master

 Syntax

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

 Description

    ypwhich tells which NIS server supplies network information service ser-
    vices to a NIS client or which system is the master for a map.  If
    invoked without arguments, it cites the NIS server for the local machine.
    If hostname is specified, that machine is queried to find out which NIS
    master it is using.

    Refer to ypfiles(NF) and ypserv(NADM) for an overview of the network in-
    formation service.

 Options


    -d      use domain instead of the default domain

    -V1     Which server is serving v.1 NIS protocol 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.

    -t mapname
            inhibit nickname translation.  This is useful if there is a map-
            name identical to a nickname.

    -m      Find the master NIS server for a map.  No hostname can be speci-
            fied with -m.  mname can be a mapname or a nickname for a map.

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