Title: Custom DDNS - How to see the HTTP Response
Post by: Vinez on May 06, 2021, 03:28:59 pm

Hello all,

Hope you can help me, I have searched the forum but found no related posts so here i go

I am setting up a custom ddns with my registrar, I have it fully configured, however i need to troubleshoot it by viewing the http response. i have turned on verbose logging and can see some messages in the logs. However i need to see the full http response.... How can i get this information? Do i need to setup SSH access and find it in the logs somewhere else? Is it not saved in the logging?

Thanks for helping in advance !

Other then what you have already done I'm not sure if that's available in OPNsense and it doesn't look to be a feature of the plugin.  I normally just get a DDNS update tool that works with your registrar (or a command line tool like noipy) that allows you to see the full response.

Just try the updating url in your browser and see what you get. The DDNS service will usually respond with something like IPv4: <address> or IPv6: <address> whet it succeed

Thanks for help!

How could I then confirm the curl command is running? Maybe my problem is in the syntax I am using I have to following filled in in the "update url" field.

curl X PATCH \ -H "Content-Type: application/json" \ -H "Authorization: Bearer KEYHERE" \ -d ' {   "dnsEntry": {     "name": "www",     "expire": 60,     "type": "A",     "content": "%IP%"   }  }  ' \ "ADRESSHERE"

in the logs it says it successfully updates the ip but I think it only updates the cache, I think it is not running the curl command. I tried looking with the packet capture with no success. I can confirm my curl command is working in "Visual Code". so maybe my syntax is wrong for opnsense. sorry I have tried to look for examples of custom dns setups but could not find any examples. How would I convert to an URL?

Again your help is greatly appreciated !

Few hours later

I am nearly there XD, I have edited the plugins php file to support my provider TransIP the api looks similar to that of DigitalOcean.

/services_dyndns_edit.php: Dynamic DNS Record ID (): PAYLOAD: {"error":"Please supply the 'dnsEntries' parameter"}

That is how far I am now...

something is wrong with my array syntax in the code below:

$hostData = array("data" => "'dnsEntry': {
                                               'name': 'www',
                                               'expire': 60,
                                               'type': 'A',
                                               'content': '$this->_dnsIP' }");

I have tried many things but new to php, maybe you can see or spot the problem?

All solved now, I can put in a pull request on GitHub if you are interested in adding the ISP TransIP to the list of supported ISP's.

Nice, I'd be interested in that too, as I'm planning to migrate my domains to TransIP soon.

I'm also interested in TransIP ddns support. I did not see a pull request yet. Is your code available somewhere?

Thanks,
