NAME

yppush - force propagation of a changed YP map

SYNOPSIS

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

DESCRIPTION

yppush copies a new version of a YP name service map from the master YP server to the slave YP servers. It is normally run only on the master YP server by the Makefile in /var/yp after the master databases are changed. It first constructs a list of YP server hosts by reading the YP 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 YP servers run. A transfer map request is sent to the YP server at each host, along with the information needed by the transfer agent (the program which 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(4) and ypserv(1M) for an overview of the YP name service. The following optionas are available:

-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.
