ypset(1M)                                                  ypset(1M)


       NAME
             ypset - point ypbind at a particular NIS server

       SYNOPSIS
             /usr/sbin/ypset [-d ypdomain] [-h host] server

       DESCRIPTION
             The ypset command tells ypbind to get Network Information
             Service (NIS) services for the specified ypdomain from the
             ypserv process running on server.  If server is down, or is
             not running ypserv, this is not discovered until the NIS
             client process tries to get a binding for the domain.  At this
             point, the binding set by ypset will be tested by ypbind.  If
             the binding is invalid, ypbind will attempt to rebind for the
             same domain.

       USAGE
             In order to run ypset, ypbind must be initiated with the
             -ypset or -ypsetme options.  See ypserv(1M).

             ypset is useful for binding a client node which is not on a
             broadcast net, or is on a broadcast net which is not running
             the NIS server host.  It also is useful for debugging NIS
             client applications, for instance where the NIS map only
             exists at a single NIS server.

             In cases where several hosts on the local net are supplying
             NIS services, it is possible for ypbind to rebind to another
             host even while you attempt to find out if the ypset operation
             succeeded. For example, you can type:

                   # ypset host1
                   # ypwhich
                   host2

             which can be confusing.  This is a function of the NIS
             subsystem's attempt to load-balance among the available NIS
             servers, and occurs when host1 does not respond to ypbind
             because it is not running ypserv (or is overloaded), and
             host2, running ypserv, gets the binding.

             server indicates the NIS server to bind to, and must be
             specified as a name.  This will work only if the node has a
             current valid binding for the domain in question, and ypbind
             has been set to allow use of ypset.  In most cases, server
             should be specified as an IP address.

            ypset tries to bind ypbind over a datagram transport first.
            Datagram Transports are recommended for higher performance.
            The NIS library calls, yp_enum, yp_all, yp_next, and yp_first
            use circuit transports regardless of the ``main'' transport
            being used.

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

         Options
            ypset takes the following options:

            -h host         Set ypbind's binding on host, instead of
                            locally.  host must be specified as a name.

            -d ypdomain     Use ypdomain, instead of the default domain.
