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 .Nm yppush determines the names of the slave servers for a domain by searching the .Pa ypservers map. Once it has a complete list of slave servers, it sends a request to each of them to initiate a map transfer, which is done 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 status or error messages .Nm yppush receives from .Xr ypxfr 8 will be printed to stdout. .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 host system is used by default. .It Fl v Verbose mode: causes .Nm yppush to print debugging messages as it runs. .Sh FILES .Bl -tag -width Pa -compact .It Pa /var/yp/[domainname]/ypservers The NIS ypservers map containing the names of all servers in a particular NIS domain. .El .Sh SEE ALSO .Xr ypserv 8 , .Xr ypxfr 8 , .Xr yp 8 .Sh BUGS The mechanism for transfering NIS maps in NIS version 1 is different that that in NIS version 2. This version of .Nm yppush has support for transfering maps to NIS version 1 systems, but this support has not been tested and is not guaranteed to work. Fortunately, the majority of systems today use NIS version 2. .Sh LICENSE This program is covered by the GNU Public License version 2. .Sh AUTHOR Tobias Reber (original Linux version) .br Bill Paul (port to FreeBSD and various changes)
