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.

-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
