hprop

HPROP(8)						    BSD System Manager's Manual 						  HPROP(8)

NAME

     hprop -- propagate the KDC database

SYNOPSIS

     hprop [-m file | --master-key=file] [-d file | --database=file] [--source=heimdal|mit-dump] [-r string | --v4-realm=string] [-c cell |
	   --cell=cell] [-k keytab | --keytab=keytab] [-R string | --v5-realm=string] [-D | --decrypt] [-E | --encrypt] [-n | --stdout]
	   [-v | --verbose] [--version] [-h | --help] [host[:port]] ...

DESCRIPTION

     hprop takes a principal database in a specified format and converts it into a stream of Heimdal database records. This stream can either be
     written to standard out, or (more commonly) be propagated to a hpropd(8) server running on a different machine.

     If propagating, it connects to all hosts specified on the command by opening a TCP connection to port 754 (service hprop) and sends the data-
     base in encrypted form.

     Supported options:

     -m file, --master-key=file
	     Where to find the master key to encrypt or decrypt keys with.

     -d file, --database=file
	     The database to be propagated.

     --source=heimdal|mit-dump|krb4-dump|kaserver
	     Specifies the type of the source database. Alternatives include:

		   heimdal   a Heimdal database
		   mit-dump  a MIT Kerberos 5 dump file
	     +.It Fl k Ar keytab , Fl -keytab= Ns Ar keytab The keytab to use for fetching the key to be used for authenticating to the propaga-
	     tion daemon(s). The key hprop/hostname is used from this keytab.  The default is to fetch the key from the KDC database.

     -R string, --v5-realm=string
	     Local realm override.

     -D, --decrypt
	     The encryption keys in the database can either be in clear, or encrypted with a master key. This option transmits the database with
	     unencrypted keys.

     -E, --encrypt
	     This option transmits the database with encrypted keys.

     -n, --stdout
	     Dump the database on stdout, in a format that can be fed to hpropd.

EXAMPLES

     The following will propagate a database to another machine (which should run hpropd(8)):

	   $ hprop slave-1 slave-2
