.Sh DESCRIPTION
.Nm
tells which
.Tn NIS
server supplies
.Tn NIS
services to a client, or which is the master for a map.
If invoked without arguments, it gives the
.Tn NIS
server for the local machine.
If
.Ar host
is specified, that machine is queried to find out which
.Tn NIS
server it is using.
.Pp
The options are as follows:
.Bl -tag -width Fl
.It Fl d Ar domain
Specify a domain other than the default domain.
.It Fl f
When used in conjunction with
.Fl m ,
force
.Nm
to query
.Ar host
directly, without using the local copy of
.Xr ypbind 8 .
.It Fl h Ar host
Specify a host other than localhost to query for information.
.It Fl m Op Ar mname
Find the master
.Tn NIS
server for the named map.
.Ar mname
can be a map name or nickname.
If
.Ar mname
is omitted,
.Nm
will produce a list of available maps.
.It Fl T
Use TCP protocol instead of UDP.
.It Fl t
Inhibit translation of map nicknames
to their corresponding map names.
.It Fl x
Display the map nickname table, found in
.Pa /var/yp/nicknames .
A built-in default translation table is used if

does not exist (see
.Xr nicknames 5
for details).

.Sh EXIT STATUS
.Nm
exits with a non-zero exit code if
