# 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
