HPROP(8)

NAME
hprop - propagate the KDC database

SYNOPSIS
hprop [-m file --master-key=file] [-d file --database=file] [--source=heimdal|mit-dump|krb4-dump|krb4-db|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
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|krb4-db|kaserver Specifies the type of the source database. Alternatives include:

    heimdal
        a Heimdal database
    mit-dump
        a MIT Kerberos 5 dump file
    krb4-db
        a Kerberos 4 database
    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 kadmin/hprop 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.

    -4, --v4-db Deprecated, identical to ‘--source=krb4-db’.

    -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

Copy a Kerberos 4 database to a Kerberos 5 slave:

    $ hprop --source=krb4-db -E krb5-slave

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
