ypwhich(1)                                                       ypwhich(1)




 NAME    [Toc]    [Back]
      ypwhich - list which host is Network Information System server or map
      master

 SYNOPSIS    [Toc]    [Back]
      ypwhich

      ypwhich [-d domain] [-V1 | -V2] [hostname]

      ypwhich [-d domain] [-t] [-m [mname]]

      ypwhich -x

    Remarks    [Toc]    [Back]
      The Network Information Service (NIS) was formerly known as Yellow
      Pages (yp).  Although the name has changed, the functionality of the
      service remains the same.

 DESCRIPTION    [Toc]    [Back]
      ypwhich lists the host name of the Network Information System (NIS)
      server that supplies NIS services to a NIS client.  It can also print
      the NIS server that is the master for mname.  The mname can be either
      a mapname or a map nickname.  A map nickname is a synonym by which a
      NIS map can be referenced.

      If invoked without arguments, ypwhich prints the host name of the NIS
      server serving the local machine.  If hostname is specified, that
      machine is queried to determine which NIS server it is using.

    Options    [Toc]    [Back]
      ypwhich recognizes the following command-line options and arguments:

           -d          Specify a domain other than the one returned by
                       domainname(1).

           -V1         List the server that is serving Version 1 NIS
                       protocol-speaking client processes.

           -V2         List the server that is serving Version 2 NIS
                       protocol-speaking client processes.

                       If neither version is specified, ypwhich locates the
                       server supplying the Version 2 (current) services.
                       However, if no Version 2 server is found, ypwhich
                       attempts to locate the server supplying the Version 1
                       services.  Since NIS servers and NIS clients are both
                       backward compatible, the user seldom needs to know
                       which version is being used.

           -t          Inhibit the translation of a map's nickname to its
                       corresponding mapname. For example, ypwhich -t -m

 ypwhich(1)                                                       ypwhich(1)




                       passwd fails because there is no map named passwd,
                       whereas ypwhich -m passwd translates to ypwhich -m
                       passwd.byname.  This option is useful if a mapname is
                       identical to a nickname (which is not true of any HP
                       map).

           -m [mname]  List the master NIS server for a map.  No hostname
                       can be specified with -m.  The mname can be a mapname
                       or a map nickname.  If mname is omitted, a complete
                       list of available maps and the corresponding host
                       names of the master NIS servers is produced.

           -x          Display the table that lists the nickname for each
                       NIS map.
