1 .TH YPPUSH 8 "August 2002" "YP Server" "Reference Manual"
3 yppush \- force propagation of changed NIS databases
33 copies updated NIS databases (or maps) from the master NIS server to
34 the slave servers within a NIS domain. It is normally run only on
37 after the master databases are changed.
43 line must be commented out.
46 first constructs a list of NIS slave servers by reading the NIS map
50 A destination host (or a list of hosts with multiple \-h commands)
51 can also be specified on the command line.
52 A "transfer map" request is sent to the NIS serger at each slave, along
53 with the information needed by the transfer agent ypxfr(8) to callback
54 to yppush, which may be printed the result to stderr. Messages are
55 also printed when a transfer is not possible; for instance when the request
56 message is undeliverable.
60 Specify a particular domain. The NIS domain of the local host system is
61 used by default. If the local host's domain name is not set, the domain
62 name must be specified with this flag.
65 The timeout flag is used to specify a timeout value in seconds. This timeout
68 will wait for a response from a slave server before sending a
69 map transfer request to the next slave server in the list.
72 will wait 90 seconds. For big maps, this is not long enough.
74 .BI \-\^\-parallel " #" "\fR,\fP \-p " #
76 normally performs transfers serially, meaning that it will
77 send a map transfer request to one slave server and then wait for
78 it to respond before sending the next map transfer request to the
79 next slave server. In environments with many slaves, it is more
80 efficient to initiate several map transfers at once so that the
81 transfers can take place in parallel.
82 It is not possible to run in parallel and assign a fixed port with
90 to listen on. By default,
94 to assign it a random port number.
95 It is not possible to assign a port with this option and run in parallel with
103 The host flag can be used to transfer a map to a user-specified machine or
104 group of machines instead of the list of servers contained in
107 map. A list of hosts can be specified by using multiple
115 to print debugging messages as it runs. Note specifying this flag twice
126 The mechanism for transferring NIS maps in NIS v1 is different
127 that that in NIS version 2. This version of
129 has support for transferring maps to NIS v2 systems only.
