Propagating an NIS map
Propagating a map means moving it from place to place,
generally from the NIS master server to an NIS
slave or copy-only server. Initially, the map is moved at system startup.
Maps are not propagated to clients because clients request map information
from servers rather than storing the maps themselves.
After you initialize an NIS nonmaster server, ypxfr(NADM) transfers updated maps from the master server. The ypxfr command can be run in the following ways:
You can capture ypxfr's transfer attempts and results in the logfile /usr/adm/nislog. If this file exists, results are appended to it. You are responsible for limiting the size of this file. To turn off logging, remove or rename this file. Refer to the ypxfr(NADM) manual page for more information about the logfile.
Methods for transferring updated maps are described in the following sections.
