This protocol allows it to transfer raw map database files from +the NIS master server and can be many times faster than the standard +transfer method, particularly for very large NIS maps. The +.Nm ypxfr +command will check to see if the +.Xr rpc.ypxfrd 8 +server is registered on the NIS master server and attempt to use +it if it is present. If it isn't it will fall back to the standard +transfer method, copying the map contents from +.Xr ypserv 8 +and creating new maps instead. +.Pp +Note that while the FreeBSD ypxfrd protocol is conceptually similar +to the SunOS ypxfrd protocol, FreeBSD's protocol is not compatible with +Sun's, therefore it will not work with Sun's ypxfrd server. FreeBSD +slave systems can still transfer maps from any non-FreeBSD NIS server, +however they will only be able to take advantage of the faster protocol +if the master server is also running FreeBSD. .Sh OPTIONS The following options and flags are supported by .Nm ypxfr : |
