ypset - point ypbind at a particular server
/usr/sbin/ypset [-V1 | -V2] [-d domain] [-h host] server
-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, 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.
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
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.
