NAME

     ypwhich -- return hostname of NIS server of map master

SYNOPSIS

     ypwhich [-T] [-d domain] [[-h] host]
     ypwhich [-fTt] [-d domain] [-h host] -m [mname]
     ypwhich -x

DESCRIPTION

     ypwhich tells which NIS server supplies NIS services to a client, or which is the master for a map.  If invoked without arguments, it gives
     the NIS server for the local machine.  If host is specified, that machine is queried to find out which NIS server it is using.

     The options are as follows:

     -d domain	 Specify a domain other than the default domain.

     -f 	 When used in conjunction with -m, force ypwhich to query host directly, without using the local copy of ypbind(8).

     -h host	 Specify a host other than localhost to query for information.

     -m [mname]  Find the master NIS server for the named map.	mname can be a map name or nickname.  If mname is omitted, ypwhich will produce a
		 list of available maps.

     -T 	 Use TCP protocol instead of UDP.

     -t 	 Inhibit translation of map nicknames to their corresponding map names.

     -x 	 Display the map nickname table, found in /var/yp/nicknames.  A built-in default translation table is used if /var/yp/nicknames
		 does not exist (see nicknames(5) for details).

EXIT STATUS

     ypwhich exits with a non-zero exit code if -m is used, and there was a problem in determining the map's master.

NAME

       ypset - point ypbind at a particular server

SYNOPSIS

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

DESCRIPTION

       In order to run ypset, ypbind must be initiated with the -ypset or -ypsetme options. See ypbind(1M). ypset tells ypbind to get NIS services
       for the specified ypdomain from the ypserv process running on server. If server is down, or is not running ypserv, this might not  be  dis-
       covered	until an NIS client process tries to obtain a binding for the domain. At this point, the binding set by ypset is tested by ypbind.
       If the binding is invalid, ypbind attempts to rebind for the same domain.

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

       Where  several  hosts on the local net are supplying NIS services, ypbind can rebind to another host, even while you attempt to find out if
       the ypset operation succeeded.  For example, if you enter the ypset command below, you might get the subsequent response from ypwhich:

	 example% ypset host1
	 example% ypwhich
	 host2

       The sequence shown above 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, obtains the binding.

       server  indicates  which NIS server to bind to, and must be specified as a name or an IP address. This works 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 over a connectionless transport. The NIS library call, yp_all(), uses connection-oriented transport and derives the NIS
       server's address  based on the connectionless address supplied by ypset.

       Refer to ypfiles(4) for an overview of the NIS name service.

OPTIONS

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

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