.\"O .SH DESCRIPTION
.SH ÀâÌÀ
.LP
.\"O .B yppush
.\"O copies updated NIS databases (or maps) from the master NIS server to
.\"O the slave servers within a NIS domain. It is normally run only on
.\"O the NIS master by
.\"O .I /var/yp/Makefile
.\"O after the master databases are changed.
.\"O .I /var/yp/Makefile
.\"O does not invoke
.\"O .B yppush
.\"O by default, the
.\"O .B NOPUSH=true
.\"O line must be commented out.

.\"O first constructs a list of NIS slave servers by reading the NIS map
.\"O .B ypservers
.\"O within the
.\"O .I domain.
.\"O A destination host (or a list of hosts with multiple \-h commands)
.\"O can also be specified on the command line.
.\"O A "transfer map" request is sent to the NIS serger at each slave, along
.\"O with the information needed by the transfer agent ypxfr(8) to callback
.\"O to yppush, which may be printed the result to stderr. Messages are
.\"O also pritned when a transfer is not possible; for instance when the request
.\"O message is undeliverable.

.BI "\-t " timeout
.\"O The timeout flag is used to specify a timeout value in seconds. This timeout
.\"O controls how long
.\"O .B yppush
.\"O will wait for a response from a slave server before sending a
.\"O map transfer request to the next slave server in the list.
.\"O By default,
.\"O .B yppush
.\"O will wait 90 seconds. For big maps, this is not long enough.

.\"O normally performs transfers serially, meaning that it will
.\"O send a map transfer request to one slave server and then wait for
.\"O it to respond before sending the next map transfer request to the

.\"O efficient to initiate several map transfers at once so that the
.\"O transfers can take place in parallel.
