NAME

hprop - propagate the KDC database

SYNOPSIS

-words [-m file | --master-key= file ] [-d file | --database= file ] [--source= heimdal|mit-dump|krb4-dump|kaserver ] [-r string | --v4-realm= string ] [-c cell | --cell= cell ] [-S | --kaspecials ] [-k keytab | --keytab= keytab ] [-R string | --v5-realm= string ] [-D | --decrypt ] [-E | --encrypt ] [-n | --stdout ] [-v | --verbose ] [--version ] [-h | --help ] [host [: port ] ] ...

DESCRIPTION

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:

heimdal

a Heimdal database

mit-dump

a MIT Kerberos 5 dump file

krb4-dump

a Kerberos 4 dump file

kaserver

an AFS kaserver database

-k keytab --keytab= 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 options are only valid if hprop is compiled with support for Kerberos 4 (kaserver).

-r string --v4-realm= string

v4 realm to use.

-c cell --cell= cell

The AFS cell name, used if reading a kaserver database.

-S --kaspecials

Also dump the principals marked as special in the kaserver database.

-K --ka-db

Deprecated, identical to `--source=kaserver'

EXAMPLES

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

 $ hprop slave-1 slave-2
 

Convert a Kerberos 4 dump-file for use with a Heimdal KDC:

 $ hprop -n --source=krb4-dump -d /var/kerberos/principal.dump \
   --master-key=/.k | hpropd -n
