yppush(1Mnis)


yppush -- force propagation of a changed NIS map

Synopsis

/usr/sbin/yppush [-v] [-d ypdomain] mapname

Description

The yppush command copies a new version of the named Network Information Service (NIS) map from the master NIS server to the slave NIS servers.

Options

yppush takes the following options:

-v
Verbose. Print messages when each server is called, and for each response. If this flag is omitted, only error messages are printed.

-d ypdomain
Specify a ypdomain other than the default domain.

Files


/var/yp/ypdomain/ypservers.dir
local file

/var/yp/ypdomain/ypservers.pag
local file

/var/yp

Usage

yppush is normally run only on the master NIS server by the Makefile in /var/yp after the master databases are changed. It first constructs a list of NIS server hosts by reading the NIS map ypservers within the ypdomain, or if the map is not set up, the local file is used. Keys within the map ypservers are the ASCII names of the machines on which the NIS servers run.

A ``transfer map'' request is sent to the NIS server at each host, along with the information needed by the transfer agent (the program that actually moves the map) to call back the yppush. When the attempt has completed (successfully or not), and the transfer agent has sent yppush a status message, the results may be printed to stdout. Messages are also printed when a transfer is not possible; for instance when the request message is undeliverable, or when the timeout period on responses has expired.

Refer to ypfiles(4nis) and ypserv(1Mnis) for an overview of the NIS service.
