.Sh DESCRIPTION
|
|
|
|
.Nm yppush
|
|
|
|
distributes updated NIS databases (or
|
|
|
|
.Pa maps )
|
|
|
|
from an NIS master server to NIS slave servers within an NIS
|
|
|
|
domain. It is normally only run on the NIS master by
|
|
|
|
.Pa /var/yp/Makefile
|
|
|
|
whenever any of the NIS maps are updated. Note that
|
|
|
|
.Pa /var/yp/Makefile
|
|
|
|
does not invoke
|
|
|
|
.Nm yppush
|
|
|
|
by default: the
|
|
|
|
.Nm NOPUSH=True
|
|
|
|
entry in the Makefile must first be commented out
|
|
|
|
(the default FreeBSD configuration assumes a small network with only
|
|
|
|
a single NIS server; in such a configuration,
|
|
|
|
.Nm yppush
|
|
|
|
is not needed).
|
|
|
|
.Pp
|
|
|
|
By default,
|
|
|
|
.Nm yppush
|
|
|
|
determines the names of the slave servers for a domain by searching the
|
|
|
|
.Pa ypservers
|
|
|
|
map. A destination host (or a list of hosts) can also be manually
|
|
|
|
specified on the command line.
|
|
|
|
Once it has a complete list of slave servers, it sends a 'map transfer'
|
|
|
|
request to each slave, which in turn reads a copy of the map from
|
|
|
|
the master NIS server using
|
|
|
|
.Xr ypxfr 8 .
|
|
|
|
Included within each request is the name of the map to be copied
|
|
|
|
and some special information required by
|
|
|
|
.Xr ypxfr 8
|
|
|
|
to successfully 'callback' to
|
|
|
|
.Nm yppush
|
|
|
|
and carry out the transfer. Any error messages
|
|
|
|
.Nm yppush
|
|
|
|
receives from
|
|
|
|
.Xr ypxfr 8
|
|
|
|
via callback will be printed to stderr.
|
|
|
|
.Pp
|
|
|
|
.Sh OPTIONS
|
|
|
|
The following options are supported by
|
|
|
|
.Nm yppush :
|
|
|
|
.Bl -tag -width flag
|
|
|
|
.It Fl d Ar domain
|
|
|
|
Specify 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.
|
|
|
|
.It Fl t Ar timeout
|
|
|
|
The
|
|
|
|
.Fl t
|
|
|
|
flag is used to specify a timeout value in seconds. This timeout
|
|
|
|
controls how long
|
|
|
|
.Nm yppush
|
|
|
|
will wait for a response from a slave server before sending a
|
|
|
|
map transfer request to the next slave server in its list.
|
|
|
|
.It Fl j Ar #parallel jobs
|
|
|
|
.Nm 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 moving on 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. The
|
|
|
|
.Fl j
|
|
|
|
flag is used to specify the desired number of parallel jobs:
|
|
|
|
.Nm yppush
|
|
|
|
will initiate the specified number of transfers immediately and
|
|
|
|
listen for responses. If the number of specified parallel jobs is
|
|
|
|
less than the number of slave servers,
|
|
|
|
.Nm yppush
|
|
|
|
will initiate only the number of specified jobs and then wait
|
|
|
|
for some of them to finish before starting any more.
|
|
|
|
.Pp
|
|
|
|
Note that
|
|
|
|
.Nm yppush
|
|
|
|
handles callbacks asynchronously, which means that it will collect
|
|
|
|
and display the callback information received from
|
|
|
|
.Xr ypxfr 8
|
|
|
|
as soon as it arrives, even it arrives before all of the map
|
|
|
|
transfer requests have been sent.
|
|
|
|
.It Fl h Ar host
|
|
|
|
The
|
|
|
|
.Fl h
|
|
|
|
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
|
|
|
|
.Pa ypservers
|
|
|
|
map. A list of hosts can be specified by using multiple
|
|
|
|
instances of the
|
|
|
|
.Fl h
|
|
|
|
flag.
|
|
|
|
.It Fl p Ar path
|
|
|
|
By default,
|
|
|
|
.Nm yppush
|
|
|
|
expects all the local NIS maps to be stored under
|
|
|
|
.Pa /var/yp .
|
|
|
|
The
|
|
|
|
.Fl p
|
|
|
|
flag can be used to specify an alternate path in the event that
|
|
|
|
the system administrator decides to store the NIS maps somewhere else.
|
|
|
|
.It Fl v
|
|
|
|
Verbose mode: causes
|
|
|
|
.Nm yppush
|
1996-04-03 03:24:03 +00:00
|
|
|
to print debugging messages as it runs. Specifying this flag twice
|
1996-01-12 07:03:33 +00:00
|
|
|
makes
|
|
|
|
.Nm yppush
|
|
|
|
even more verbose.

.Sh BUGS

1996-01-30 13:52:50 +00:00
|
|
|
The mechanism for transferring NIS maps in NIS v1 is different
|
1996-04-03 03:24:03 +00:00
|
|
|
than that in NIS version 2. This version of
|
1996-01-12 07:03:33 +00:00
|
|
|
.Nm yppush
|
1996-01-30 13:52:50 +00:00
|
|
|
has support for transferring maps to NIS v2 systems only.
