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 database 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:

a Heimdal database
a MIT Kerberos 5 dump file

+.It Fl k Ar keytab , Fl Fl keytab= Ns Ar keytab The keytab to use for fetching the key to be used for authenticating to the propagation 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.


The following will propagate a database to another machine (which should run hpropd(8)):
$ hprop slave-1 slave-2
