DNS-O-Matic dynamic DNS broken on many routers

Post by ittroll » Thu Aug 06, 2020 10:09 am

It would seem that OpenDNS are now redirecting logins to the DNS-O-Matic service which has broken the update mechanism used by my BiPAC 8900AX R2. :evil:

I suspect other Billion routers will be affected as are routers from other manufacturers. The change happened mid-July, OpenDNS have not yet responded to any support tickets.

Is there any chance that this can be fixed in the firmware? Alternatively, it would be great if more Dynamic DNS services could be supported, especially a Custom URL option (like the one in DD-WRT) which would open up many more options.

Current theory is that DNS-O-Matic implemented a 301 redirect from http to https which the ddns client does not support.

ddnsd: update all.dnsomatic.com request failed. Please check the setting.

If this is the case, sounds like it would be simple to fix in firmware.

Just being able to schedule a ping of a custom URL would do the trick.

Folk on the DD-WRT forum have found that changing the URL to the following works.

Code: Select all

https://updates.dnsomatic.com:443/nic/update?hostname=
Hopefully engineering can make this simple change, or better still, allow us to customise the URL.

Attached is the DNS-O-Matic fix for the 8900 series (8900X-R3, 8900AX-1600R2 and 8900AX-2400)

I just tried Zcomax8900AX-R2_2.52.d4.afw on my 8900AX-1600 R2 and it says it is an illegal image. :o

Re-downloaded and tried again but got the same message.

I am currently running 2.52.d3

That one installed OK and does indeed fix the DNS-O-Matic updates. :D

Many thanks to all involved in this fix.
