Or you can use all.dnsomatic.com which is a special wildcard host name. This will update all the domains which you have setup in your DNS-O-Matic account.

That's true, I'd forgotten that bit!

PS: SSH'd into router, and couldn't see any evidence that the DDNS daemon was running. I think that it tries to start, but fails. Tried to find log files, but OS very locked down.

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

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.

Still awaiting feedback from our engineers

Further investigation: sending a http request to http://username:password@updates.dnsoma ... urhostname, does result in a re-direct to https://updates.dnsomatic.com, but it still returns 'good xxx.xxx.xxx.xxx', so I can't see why the ddns daemon would reject it.

Whilst browsers support redirection it would appear that the DDNS daemon has not be coded to do so.

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.

I have a test firmware for the Bipac 8800NLR2, which our engineers hope will resolve the issue with DNS-O-Matic.

If anyway one wants to test please feel free to, and let me know the results, if the results are positive we can roll out the fix for other models.

The firmware above seems to resolve the issues with DNS-O-Matic (confirmed by another user)

Great news! I have an 8900AX-1600 R2 and so hopefully this fix can be rolled out to this and other models.
