NAME

ypset — bind to particular Network Information Service server

SYNOPSIS

/usr/sbin/ypset [-V1] [-h host] [-d domain] server

Remarks

The Network Information Service (NIS) was formerly known as Yellow Pages (yp). Although the name has changed, the functionality of the service remains the same.

DESCRIPTION

ypset tells ypbind to get Network Information Service (NIS) services for the specified domain from the ypserv process running on server (see ypserv(1M) and ypbind(1M)). server is the NIS server that the NIS client binds to, and is specified as either a host name or an IP address. If server is down or is not running ypserv, this is not discovered until a local NIS client process tries to obtain a binding for the domain. The ypbind daemon then tests the binding set by ypset. If the binding cannot be made to the requested server, ypbind attempts to rebind to another server in the same domain.

The ypset command is useful for binding a client node that is not on a broadcast network, since broadcasting is the method by which ypbind locates a NIS server. If a client node exists on a broadcast network which has no NIS server running, and if there is a network with one running that is available via a gateway, ypset can establish a binding through that gateway. It is also useful for debugging NIS client applications such as when a NIS map exists only at a single NIS server.

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, typing ypset host1 followed by ypwhich and receiving the reply host2 may be confusing. It could occur when host1 does not respond to ypbind because its ypserv process is not running or is overloaded, and host2, running ypserv, gets the binding.

Refer to ypfiles(4) and ypserv(1M) for an overview of the Network Information Service.

Options

ypset recognizes the following options and command-line arguments:

-V1

Bind server for the (old) Version 1 NIS protocol.

-h host

Set the binding on host instead of locally. host can be specified as a host name or an IP address.

-d domain

Use domain instead of the default domain returned by domainname (see domainname(1)).

DIAGNOTICS

Sorry, ypbind on host 'name' has rejected your request.

The user is not root, or ypbind was run without the -ypset flags. See ypserv(1M) for explanations of the -ypset flags.

Sorry, I couldn't send my rpc message to ypbind on host 'name'.

The user is not root, or ypbind was run without one of the -ypset flags. See ypserv(1M) for explanations of the -ypset flags.

WARNINGS

The server is the NIS server to bind to, specified as either a host name or an IP address. If server is a host name, ypset uses the NIS services' hosts database (built from /etc/hosts on the master server) to resolve the name to an IP address. This process works only if the node currently has a valid binding for the domain in question. In most cases, server should be specified as an IP address.

The NIS Version 1 protocol will not be available in a future HP-UX release. HP recommends that you use the next version of this protocol.
