Cloudflare dynamic dns not working
-
There seems to be some confusion on what the valid parameters are for the cloudflare client api. So just to help get this ball moving in the right direction here are the relevant parts of the api.
Link to full api - https://www.cloudflare.com/docs/client-api.html#s5.22 - Client Operations
All GET/POST requests should be directed at the client gateway interface, located at:https://www.cloudflare.com/api_json.html
2.1 - Basic Parameters
Every GET/POST request must include at the following basic parameter(s):"tkn" - This is the API key made available on your Account page.
"email" - The e-mail address associated with the API key.
"a" - To define which request is being made, the client should POST an "a" parameter. The "a" specifies which action you'd like to perform. Specific actions are described in Section 3 below.5.2 - "rec_edit" – Edit a DNS record
Edit a DNS record for a zone. The record will be updated to the data passed through arguments here.Input:
Requires the basic parameters described in Section 2.1 of this document. In addition you must pass the following parameters:"z" - The target domain
"type" - Type of DNS record. Values include: [A/CNAME/MX/TXT/SPF/AAAA/NS/SRV/LOC]
"id" - DNS Record ID. Available by using the rec_load_all call.
"name" - Name of the DNS record.
"content" - The content of the DNS record, will depend on the the type of record being added
"ttl" - TTL of record in seconds. 1 = Automatic, otherwise, value must in between 120 and 86400 seconds.
"service_mode"[applies to A/AAAA/CNAME] - Status of CloudFlare Proxy, 1 = orange cloud, 0 = grey cloud.The minimum amount of information that you would need to provide an update for foo.bar.com with the current IPv4 address is:
tkn=CLOUDFLAREAPI
email=me@bar.com
a=rec_edit
z=bar.com
type=A
name=foo
content=%IP%To manually update the IP for foo.bar.com you should be able to run the following -
curl https://www.cloudflare.com/api_json.html?a=rec_edit&tkn=CLOUDFLAREAPI&email=me@bar.com&a=rec_edit&z=bar.com&type=A&name=foo&content=%IP% -
You must include an `a' parameter, with a value of wl|chl|nul|ban|comm_news|devmode|sec_lvl|ipv46|ob|cache_lvl|fpurge_ts|async|mirage2|img.q|minify|stats|zone_check|zone_ips|zone_ss|vote_ss|app|ip_lkup|set|app_req|app_req_list|app_version|custom_cert_set|custom_cert_purge|custom_cert_load_multi|custom_cert_load|ersubmit|zoneupload|user_notification_remove|pref_set|zone_file_purge|zone_file_refresh|zone_settings Additionally, email and tkn parameters are required.That message that comes back interactively doesn ot mention "rec_edit" at all. Someone who uses Cloudflare should tell them that the message is old/out-of-date - because that causes confusion to people trying to get their client working!
curl https://www.cloudflare.com/api_json.html?a=rec_edit&tkn=CLOUDFLAREAPI&email=me@bar.com&a=rec_edit&z=bar.com&type=A&name=foo&content=%IP%"a=rec_edit" got repeated twice in there - I guess it will not break? But should not be necessary.
Someone post an actual successful update URL string (with their password "tkn" and domain name obfuscated) and then we can easily make the pfSense code do the correct thing.

For me it wasn't working either, because you need to add the record_id, which you need to request with the rec_load_all API function before.
I extended the dyndns.class in /etc/inc/, so now it's working for me.
I can now use the Web-Interface, albeit MX and Wildcards are not working.
It's a rather dirty fix imo, but it's working, for me ;D.Edit:

Hello,
… So we have some new update for this planned... ? :-\
ps : for people like me who cannot wait for pfs cloudflare, try this => http://www.ubuntugeek.com/how-to-use-cloudflare-as-a-ddclient-provider-under-ubuntu.html ... It works! :D

Thank you. Great first post & welcome to the forums! Works for me too, hopefully this will get rolled into pfSense soon.

I didn't like how much was hardcoded, so here is what I did to get it working on mine. I am currently running 2.2 but the fork/commit is based on the current master. The majority of this was from brainlesscurls: https://github.com/brainlesscurls/pfsense/commit/4f3ce17b98919e464044cbc983e31549b595bdc3
Here is the code that I created, it does not correctly handle the response coming back or check if cached differs at all:

I have sorted this not after a lot of research.
I stumbled across this website: http://blog.t-m-s.co.uk/ with a blog post with exactly our issue and solution with a very good explanation on the use of the CloudFlare API.
I recommend reading through this completely to understand what is going on.
After following the steps in the website and tweaking a few things to cater for my needs it's up and running beautifully.

I actually worked out a fix at the dyndns.class file:
CloudFlare now requires a "record ID" in order to update an address, for such I did another curl call before pfsense change of the IP in order to get the record ID from the target.
Also the CloudFlare URL is quite different from the one in the original file of pfSense.
if you open the /etc/inc/dyndns.class, line 607, the original case looks like:
case 'cloudflare':
$needsIP = TRUE;
$dnsServer ='www.cloudflare.com';
$dnsHost = str_replace(' ','', $this->_dnsHost);
$URL = "https://{$dnsServer}/api.html?a=DIUP&email={$this->_dnsUser}&tkn={$this->_dnsPass}&ip={$this->_dnsIP}&hosts={$dnsHost}";
curl_setopt($ch, CURLOPT_URL, $URL);
break;I change it to:
case 'cloudflare':
$needsIP = TRUE;
$dnsServer ='www.cloudflare.com';
list ($host,$zone) = split('.', $this->_dnsHost, 2);
$getid = "https://$dnsServer/api_json.html?a=rec_load_all&tkn={$this->_dnsPass}&email={$this->_dnsUser}&z=$zone";
$crl = curl_init();
$timeout = 5;
curl_setopt ($crl, CURLOPT_URL,$getid);
curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
$ids = curl_exec($crl);
curl_close($crl);
$json_ids = json_decode($ids, true);
$jsonIterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($json_ids),RecursiveIteratorIterator::SELF_FIRST);
$recid=0;
foreach ($jsonIterator as $key => $val) { if(!is_array($val)) { if ($key == "rec_id") { $recid=$val; } if ($key == "name" and $val == $this->_dnsHost) { break; } } }
$dnsHost = str_replace(' ','', $this->_dnsHost);
$URL = "https://{$dnsServer}/api_json.html?a=rec_edit&tkn={$this->_dnsPass}&email={$this->_dnsUser}&id=$recid&z=$zone&type=A&name=$host&content={$this->_dnsIP}&service_mode=1&ttl=1";
curl_setopt($ch, CURLOPT_URL, $URL);
break;In the Dynamic DNS interface all the information is pretty much the same, except the password must be the Token ID found at https://www.cloudflare.com/my-account ("Your API key is: ")
With this change he is automatically updating CloudFlare but the cached IP address still 0.0.0.0, something else must change to make this value also correct.
I hope this help to fix the problem for other people as well.

I hope this help to fix the problem for other people as well.I tried your fix but it just makes pfsense spit out crash reports and it still don't appear to be updating.I didn't delete my old cloudflare entry and start over so I assume that is what caused it to not load the changes. -
So after spending some time at this I came up with a working solution that uses CloudFlare's latest API. Be sure to use your account API key for the password field instead of your account password.
It updates the cached IP also and handles some basic errors.
Tested on 2.2.3-RELEASE 32 bit and 64 bit systems without errors.
If you choose "Diagnostics -> Edit File" then open the "/etc/inc/dyndns.class" file and edit the lines to the ones below.

Thank you det0nat3.
That patch pretty much covers all that I was looking for.
-
wonders what's wrong with diff …
-
Is this still broken in 2.2.3?
Shouldn't it be possible to use a "custom" dyndns entry instead of the api?
Edit:
I used @__det0nat3__ solution, thanks! -
Thank you det0nat3!!!
n1!
I'm on 2.2.3-RELEASE (amd64) and still not working as is but your fix did the trick!
Would be great if it was in 2.2.4 ;)

Just updated to 2.2.4 and now getting this error:
/rc.dyndns.update: DynDNS: PAYLOAD: E_INVLDINPUT
DynDNS was previously working flawlessly after following this thread, any suggestions? Do I just redo the edit?

Yeah, just happend to me too, seems like the update did an overwrite of the file.
Is there an ETA of a fix for this? -

Has anyone had any luck on the 2.2.5 update? Aparently CloudFlare DNS was fixed.
When I try this I get "Invalid HostName" - I have tried the zone ID, hostname but no luck.

On 2.2.5, Works no problem for me as of right now. I used the API. Never had it set up before. Got to this article when using my password returned 0.0.0.0
use your CloudFlare API

To add onto what humungus said about the API. On 2.2.5 when trying to setup a DDNS entry with CloudFlare instead of entering in the password for your CloudFlare account put in the API Key from the CloudFlare My Account page.
