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 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
+.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. This is the default if no option is supplied.
- -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
