I recently followed this great thread about adding DDNS functionality to VYOS DHCP Server.
It worked as described and I was able to get DDNS working and updating a bind DNS server.
However it seems some devices on my network all report the same hostname (because who would buy multiple smart plugs?).
Anyway to get round this I planned on setting the hostname using the “ddns-hostname” option using the “static-mapping-parameters” setting which should insert it into the “host” block.
I seem to be able to set other custom DHCP options using this method but setting ddns-hostname fails to commit saying “check your options!”
This is confirmed working on VYOS 1.4-rolling-202306010317 (running isc-dhcpd-4.4.3-P1). It should also work with Infoblox (NIOS and Bloxone DDI with some tweaking to the shared key) however if you have access to Infoblox use DHCP relay or run the B1DDI KVM image on the VYOS box. Infoblox makes this whole thing soooo much easier.
Hi @Shrug666! NICE job on fixing the issue and finding a solution, and thank you for sharing your working config! It’s always helpful to contribute to the community and help others facing similar challenges.
