ypset - point ypbind at a particular server
/usr/sbin/ypset [-V1 | -V2] [-d domain] [-h host] server
Bind server for the (old) v.1 NIS protocol. 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, then attempts to set the
domain for the (old) v.1 protocol. Set ypbind's
binding on host, instead of locally. The host can
be specified as a name or as an address. Use
domain, instead of the default domain.
The ypset command tells ypbind to get Network Information
Service (NIS) map information 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 will
attempt to rebind for the same domain.
Note
The ypbind process will refuse ypset requests unless
-ypset or -ypsetme are specified when ypbind is started.
The ypset command is useful for binding a client node
which is not on a broadcast net, or is on a broadcast net
which 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. 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.
The server indicates the NIS server to bind to, and can be
specified as a name or an address. If specified as a
name, ypset will attempt to use NIS services to resolve
the name to an address. This will work only if the node
has a current valid binding for the domain in question. In
most cases, server should be specified as an address.
