ypset(1M) System Administration Commands ypset(1M)NAMEypset - 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 ser‐
vices for the specified ypdomain from the ypserv process running on
server. If server is down, or is not running ypserv, this might not be
discovered 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. Spec‐
ify host as a name.
