I am trying to use DDNS to update Google domains. They have some instructions online (I am not allowed to post a url
but googling "google domain dynamic dns" provides a link to the support page I used)

Since it was not supported out of the box, I added a new entry for it in ddns_providers.conf with the URL template. I was able to create the entry, but then it fails to update saying it cannot retrieve the remote IP:

Sun Sep 29 20:01:43 2019 daemon info ddns_gargoyle[1471]: remote IP cannot be determined

I checked the source code of ddns_gargoyle and the only thing I can think would fail here is the call to gethostbyname. An nslookup of the domain fails strangely: it prints an Address 1 with the remote IP address as expected but then fails and returns an error.

I can probably do some more digging around, but I wanted to know if google domains would be supported or not since OpenWRT claims support for it but it is not in the providers for Gargoyle.

Can you share your conf entry?
It looks simple enough. Should be no reason it can't be supported.

I guess something went horribly wrong while I was trying it to get to work. I lost DNS resolution and could not get it to work again.
I restored the default configuration and manually made the changes again (replace the _ with a . for the url as I cannot paste url):

Code: Select all

service domains_google_com
	url_template                    https://[[USERNAME]]:[[PASSWORD]]@domains_google_com/nic/update?hostname=[[DOMAIN]]&myip=[[IP]]  
	required_variables              domain username password
	required_variable_names	DyDNS.DoNm,DyDNS.UsrN,DyDNS.Pssw
	success_regexp                  /^(good|nochg)/

And reconfigured from the UI and it works.

I am wondering if the changes I made manually in the ddns_gargoyle.conf are the culprit.
When I originally configured it, there was an error in the UI and it failed to save. So the second time I unchecked the enabled box, and saved.
I then looked up at the file and saw it was sourcing from internet. Since I set my modem on IP passthrough, I manually switched it to wan and then tried to start it manually. I now realize that the right way to do it was to set

Code: Select all

	ip_source	interface
	ip_interface	eth1.2

Also I noticed that these settings are lost when I update from the UI: it always revert to internet. I made the changes manually and started the ddns_gargoyle daemon from the command line for now.

Thanks

Thanks for sharing and I'm glad it is now working.
I'll add this as a new provider for an upcoming update.

You shouldn't need to change it away from using internet as a source, but you are certainly free to do so.
This setting is overwritten if you make any changes in the GUI. Most users don't need to modify this setting.
