NAME
yppush - force propagation of changed NIS databasesSYNOPSIS
/usr/sbin/yppush
[-d domain] [-t timeout]
[--parallel # | --port port]
[-h host] [-v] mapname...
DESCRIPTION
yppush copies updated NIS databases (or maps) from the master NIS server to the slave servers within a NIS domain. It is normally run only on the NIS master by /var/yp/Makefile after the master databases are changed. /var/yp/Makefile does not invoke yppush by default, the NOPUSH=true line must be commented out.OPTIONS
-d domainSpecify a particular domain. The NIS domain of
the local host system is used by default. If the local host's domain name is
not set, the domain name must be specified with this flag.
-t timeout
The timeout flag is used to specify a timeout
value in seconds. This timeout controls how long yppush will wait for a
response from a slave server before sending a map transfer request to the next
slave server in the list. By default, yppush will wait 90 seconds. For
big maps, this is not long enough.
--parallel #, -p #
yppush normally performs transfers
serially, meaning that it will send a map transfer request to one slave server
and then wait for it to respond before sending the next map transfer request
to the next slave server. In environments with many slaves, it is more
efficient to initiate several map transfers at once so that the transfers can
take place in parallel. It is not possible to run in parallel and assign a
fixed port with the --port flag
--port port
specify a port for yppush to listen on.
By default, yppush will ask portmap(8) to assign it a random
port number. It is not possible to assign a port with this option and run in
parallel with the --parallel or -p flag
-h host
The host flag can be used to transfer a map to
a user-specified machine or group of machines instead of the list of servers
contained in the ypservers map. A list of hosts can be specified by
using multiple instances of the -h flag.
-v
Verbose mode: causes yppush to print
debugging messages as it runs. Note specifying this flag twice makes
yppush even more verbose.

The mechanism for transferring NIS maps in NIS v1 is different that that in NIS version 2. This version of yppush has support for transferring maps to NIS v2 systems only.AUTHOR
