KEA-DHCP-DDNS(8) Kea KEA-DHCP-DDNS(8)

NAME

kea-dhcp-ddns - DHCP-DDNS process in Kea

SYNOPSIS

kea-dhcp-ddns [-v] [-V] [-W] [-d] [-c config-file] [-t config-file]

DESCRIPTION

The kea-dhcp-ddns service process requests an update of DNS mapping based on DHCP lease-change events. It runs as a separate process that expects to receive Name Change Requests from Kea DHCP servers.

ARGUMENTS

The arguments are as follows:

Displays the Kea version.
Displays the extended Kea version.
Displays the configuration report.
Sets the logging level to debug with extra verbosity. This is primarily for development purposes in stand-alone mode.
Specifies the configuration file with the configuration for the DHCP-DDNS server. It may also contain configuration entries for other Kea services.
Checks the syntax of the configuration file and reports the first error, if any. Note that not all parameters are completely checked; in particular, a service socket is not opened.

DOCUMENTATION

Kea comes with an extensive Kea Administrator Reference Manual that covers all aspects of running the Kea software - compilation, installation, configuration, configuration examples, and much more. Kea also features a Kea Messages Manual, which lists all possible messages Kea can print with a brief description for each of them. Both documents are available in various formats (.txt, .html, .pdf) with the Kea distribution. The Kea documentation is available at <https://kea.readthedocs.io>.

Kea source code is documented in the Kea Developer's Guide, available at <https://reports.kea.isc.org/dev_guide/>.

The Kea project website is available at <https://kea.isc.org>.

MAILING LISTS AND SUPPORT

There are two public mailing lists available for the Kea project. kea-users (kea-users at lists.isc.org) is intended for Kea users, while kea-dev (kea-dev at lists.isc.org) is intended for Kea developers, prospective contributors, and other advanced users. Both lists are available at <https://lists.isc.org>. The community provides best-effort support on both of those lists.

ISC provides professional support for Kea services. See <https://www.isc.org/kea/> for details.

HISTORY

The b10-dhcp-ddns process was first coded in May 2013 by Thomas Markwalder.

Kea became a standalone server and the BIND 10 framework was removed. The DHCP-DDNS server binary was renamed to kea-dhcp-ddns in July 2014. Kea 1.0.0 was released in December 2015.
