💖 KEA-DHCP-DDNS 💖

okay bestie, sit down, we're talking about kea-dhcp-ddns — the DHCP-DDNS process in Kea. it's giving backend queen energy and honestly? iconic.

✨ SYNOPSIS ✨

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

🌸 DESCRIPTION 🌸

so like, the kea-dhcp-ddns service process is the one that requests updates to DNS mapping, based on DHCP lease-change events. that's its whole thing. it runs as a separate process (main character, does not share a screen), and it expects to receive Name Change Requests from Kea DHCP servers. that's the vibe. it sits there, all pretty, waiting for the DHCP servers to slide into its DMs with a Name Change Request. 💅

🎀 ARGUMENTS 🎀

the arguments are as follows, no cap:

  • -v — displays the Kea version. just the version. simple. slay.
  • -V — displays the extended Kea version. yes bestie, there's more of it. 👑
  • -W — displays the configuration report.
  • -d — sets the logging level to debug with extra verbosity. this one is primarily for development purposes in stand-alone mode, so like, devs only, don't just casually use it in prod, iykyk.
  • -c config-file — specifies the configuration file with the configuration for the DHCP-DDNS server. plot twist: it may also contain configuration entries for other Kea services. multitasking queen fr fr.
  • -t config-file — checks the syntax of the configuration file and reports the first error, if any. and here's the tea: not all parameters are completely checked — in particular, a service socket is not opened. so don't go thinking a clean -t means everything's perfect, because it does not. 🙈

📚 DOCUMENTATION 📚

Kea comes with an extensive Kea Administrator Reference Manual that covers literally all aspects of running the Kea software — compilation, installation, configuration, configuration examples, and much 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. go look, it's cute. 🦋

💌 MAILING LISTS AND SUPPORT 💌

there are two public mailing lists available for the Kea project:

  • kea-users (kea-users at lists.isc.org) — intended for Kea users. that's the hangout spot for the user girlies.
  • kea-dev (kea-dev at lists.isc.org) — intended for Kea developers, prospective contributors, and other advanced users. big brain zone. 🧠✨

both lists are available at https://lists.isc.org. the community provides best-effort support on both of those lists — so like, be nice, everyone's volunteering their time. 🫶

ISC provides professional support for Kea services. see https://www.isc.org/kea/ for details. 💰
