ypset(1M) ypset(1M)
ypset - point ypbind at a particular NIS server
ypset [ -V1|-V2 ] [ -h host ] [ -d domain ] server
ypset tells ypbind(1M) to get the network information service (NIS) for
the specified domain from the ypserv process running on server. If
server is down, or isn't running ypserv, this is not discovered until an
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 attempts to rebind for the same domain.
By default, ypbind does not allow ypset operations from local or remote
hosts. ypset returns the error message
ypset: Sorry, I couldn't send my RPC message to ypbind on host nisserver
when ypbind rejects the attempt.
ypset is useful for binding a client node that is not on a broadcast net
or is on a broadcast net that isn't running an NIS server host. It also
is useful for debugging NIS client applications, for instance where an
NIS map only exists at a single NIS server host.
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. That is, you can
type ypset host1; ypwhich and get the response host2, which can be
confusing. This is a function of the NIS subsystem's attempt to loadbalance
among the available NIS servers It 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 can be specified as a name
or an IP address. If specified as a name, ypset attempt to use NIS
services to resolve the name to an IP address. This works only if the
node has a current valid binding for the domain in question. In most
cases, server should be specified as an IP address.
Refer to ypfiles(4) and ypserv(1M) for an overview of NIS.
-V1 Bind server for the (old) v.1 NIS protocol.
-V2 Bind server for the (current) v.2 NIS protocol.
If no version is supplied, ypset, first attempts to set the
domain for the (current) v.2 protocol. If this attempt
fails, ypset, attempts to set the domain for the (old) v.1
protocol.

-h host Set ypbind's binding on host, instead of locally. host can
be specified as a name or as an Internet address.
-d domain Use domain instead of the default domain.
