Dynamic DNS + one.com?

biifer

Försöker hjälpa min far som har en domän och webhosting hos one.com. Är det möjligt att använda Dynamic DNS i pfSense och uppdatera DNS som ligger hos one.com? Tanken är att ha kvar webhosting, mail o.s.v hos one.com men ha vissa subdomäner "hemma". Någon som har provat detta?

Lugico

I made a python script that lets you dynamically change the IP address a dns entry is pointing to.
So far it only works for type A record subdomains. If you need a different type, please try to reconfigure the script yourself. If you're not experienced with python, you can contact me and i will try to adapt the script.

=== IMPORTANT EDIT ===
There is ~~a new version of this script, and also~~ a GitHub Repository.
Most recent version will always be on GitHub!

The outdated script can be found here:
http://lugico.de/ddns.py
Everything below is old.
=====================

execute it like this:

python3 ddns.py youripaddress

Run this every once in a while, maby through crontab, and you should be good.

you can get your ip address in plain text from this address: https://api.ipify.org/?format=text

combining the two could look like this (on linux):

IP=$(curl https://api.ipify.org/?format=text); python3 my_ddns.py $IP

Also, i dont speak swedish, i used google translate.
If you need any help using the script, feel free to contact me through this email: main@lugico.de

@Lugico

Thank you for the script, it works perfectly for me

hellfire

@technoid-se hi! is it still working?, been looking everywhere for something like this.

Lugico

@hellfire Yes the script should still be working, but you won't need to get your IP address beforehand andymore. The script will do that for you. I can send you an updated version, that is even simpler to use.

Lugico

Ok for everyone still finding this thread:

I made a new, updated version, that is much simpler to use.
~~https://lugico.de/one_com_ddns.py~~
Most recent version can be found on GitHub

Edit the file beforehand to fit your needs. All the things you might have to change are in the top few lines. Execute it like this:

python3 one_com_ddns.py

python can be downloaded and installed from here: https://www.python.org/downloads/
or on debian / ubuntu based machines, including raspberry pi OS, it can be installed using apt:

sudo apt-get install python3

You will also need to install the requests package.

sudo pip3 install requests

or

sudo pip install requests

on windows just remove the "sudo"

@lugico Thanks a lot, this well spare me 3rd party apps & the monthly verification.

I'm adding some keywords to make users find this (both swedish and English) :

dynamic ip one.com, update DNS automatically with your dynamic ip
dynamiskt ip one.com, uppdatera dns automatiskt med ditt dynamiska ip

hellfire

@lugico couldn't get it to work, got username, PW, and id number, domain everything is correct.
I noticed the id number is different depending on what subdomain you want to change..

{"result":null,"metadata":{"messages":[{"text":"No matching order found for current user matching requested domain name","code":"CRMRST_000302","arguments":null,"type":"error"}]}}
89.160.xxx.xxx (my ip)

Lugico

@hellfire that looks like the output from the old script. try using the new one
~~https://lugico.de/one_com_ddns.py~~
EDIT: Most recent version on GitHub

hellfire

@lugico will try, your previous link to the new script, links to the old one...

hellfire

@lugico it worked fine!
.. now I just need to learn python, so it can be tweaked (would be great if it saved the last updated ip and checked if the ip has changed before it logs in and update it)

Lugico

@hellfire I just added this feature. If you click the link again you should get the new version. It saves the last IP address in a file ("lastip.txt") and only if the content of the file and the current IP address don't match, the script gets executed.

hellfire

@lugico Works perfect! thx a lot!

@Lugico Is it so that I missed this terrific script by a mere half year?
(ie. the link provided above now leads to 404 page)

Lugico

Hi @eriond
I did some restructuring on my Website and forgot about the script.
Check the link again in a few minutes, I'll update it right now.

Eriond

@lugico Excellent, thank you! If there is a way to make it permanently available, like via the wayback machine or something similar, that would be great...

Lugico

Made a pastebin with the Script in case my Website ever doesn't work.

Edit: There is a GitHub Repo now

Lugico

Hello everyone,
as of recently one.com has changed their login back end. Therefore some changes on the script were necessary.

I have updated the script to work again as of Sep. 7th 2021.

The newest version is again available on my website (direct download), pastebin and now also on GitHub

Please always use the GitHub, as it's the most recent version.

hellfire

@lugico Thank you!
Really appreciate it!

DerDomml

@lugico I literally just registered on this website to say thank you!! You are my hero for making this script. Please notify us should you ever consider not supporting this script anymore!

You could also have a look at this question over on SO. Maybe we can rely on this "network interface restarts when ISP IP changes" and automatically run the script whenever that happens!

Could you test this patch to check that it works on the Services / Dynamic DNS tab?

Tried patching this but no luck. I'm new to this so good chance I messed it up somehow but here's the log.

@viktor_g Hi, just a small heads-up. I haven't actually used or contributed to pfSense yet so this is all still very new to me. I'll look into it though and try to give you feedback asap.

You can test one.com DDNS on the latest 2.6/22.01 RC

hi how do i install it on a pfsense +

markewert

Hello @viktor_g

I am trying to get this working on 2.6.0. I receive the following error no matter what variation of hostname or FQDN I use in the Hostname and Domain Name fields:

Mar 2 04:29:39 php-fpm 67880 /services_dyndns_edit.php: Could not find one.com hostname record id

Prior to that the log entries show that it did get the IP for the correct interface. I have verified the username and password are correct. Verbose logging is enabled. I am using a TTL of 600. On the status screen it shows status as failed (red X) with a cached IP in red of 0.0.0.0.

Please let me know if there is anything I should try or other info I can send.

THANKS!

Mark

markewert

Hello again. I realized how much I was over paying one.com for DNS service so I transferred my domain to a provider that works great with pfsense dynamic DNS. So I am no longer in need of help - or able to troubleshoot this. Thanks for the help you would have provided :)

Eriond

@markewert May we know which provider you switched to? I'm not too happy with one.com either, due to their email policy changes lately.

markewert

@eriond

Sure! I switched to dynu.com. It's full featured and just works (which is what you want in DNS). It's also very reasonably priced ($9.99 a year plus one-time $21.99 if you need to transfer a domain).

Here's their privacy policy. I'd appreciate it if you notice anything similar to what is giving you concerns about one.com. Thanks!

Was hoping this would be resolved in 2.6.0 but unfortunately I'm getting the same errors as @markewert and abandoning one.com isn't really an option for me.
Still hoping this can be resolved somehow.

I registered a domain on one.com today and just found out that the one.com DDNS updater in pfsense 2.6.0 doesn't work with it.

After quite a lot of hours this afternoon though I did finally manage to figure out what the issue is and fix it. The fix is not very nice though because I have 0 experience patching pfSense and basically 0 experience with php.

But the problems are these:

pfSense tries to log in by posting the form to the same URL it gets redirected to after visiting "https://www.one.com/admin/". This might have worked in the past but it doesn't work anymore. The form now has to be posted to the url pointed to in the <form>-tag action attribute.
Ugly? fix:

-$last_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
+//$last_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
+$dom = new DOMDocument;
+$dom->loadHTML($output);
+$formTag = $dom->getElementsByTagName("form")[0];
+$last_url = $formTag->getAttribute("action");

It seems like the login form data has to be posted in a different format.

// login in
-$post_data['username'] = $this->_dnsUser;
-$post_data['password'] = $this->_dnsPass;
-$post_data['credentialId'] = '';

-curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
+curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=' . $this->_dnsUser . '&password=' . $this->_dnsPass . '&credentialId=');
+curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));

This line seems to concatenate incorrectly:

-$url = "https://www.one.com/admin/api/domains/" . $this->_dnsDomain + "/dns/custom_records";
+$url = "https://www.one.com/admin/api/domains/" . $this->_dnsDomain . "/dns/custom_records";

(Result was that $url became "0")

After this I was getting HTTP 400/500 errors when downloading this page and it seemed to be some issue with remaining curl_setopt settings I was unable to reset. But I solved it for now by running:

curl_reset($ch);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_INTERFACE, 'if!' . $realparentif);

I also replaced the CURLOPT_COOKIE and cookie extractor regex with CURLOPT_COOKIEFILE & CURLOPT_COOKIEJAR located in /var/tmp, which might not be needed and might not be the most secure option.
Final problem is that the webinterface doesn't let me save an empty hostname which makes this script unable to update the ip for the root domain. For now I made an ugly hack which forces me to create an entry called "root" which gets replaced with "" in the update script which can then update the root domain. I tried to use "@" initially because the documentation says "Cloudflare, Linode: Enter @ as the hostname to indicate an empty field." but when picking Service type "One.com" the @ is still considered an invalid character.

For now I really have to go to bed but I might try to clean this up a bit more in the coming days/weeks. I'd like to figure out if I can avoid using curl_reset and perhaps go back to using CURLOPT_COOKIE instead of COOKIEJAR and COOKIEFILE. Perhaps after this I'll try to experiment with creating an actual system patch and/or report the issue over at redmine.

@arques Today I cleaned up my patch a bit and created a proper pfSense system patch that applies cleanly to version 2.6.0. I created a redmine issue about this and attached my patch to it. It can be viewed here: https://redmine.pfsense.org/issues/14276

Well done! But it is not applying to the pfSense+ version 23.01, I got out the following error;

EDIT:
Solved! By using that URL: DynDNS Patch

Arques

@dobby_ Okay, I actually never tried to upload to patch file so I'm not sure what's wrong with it. What I did was I just pasted the contents of the file in the "Patch Contents" field, and then I created the file afterwards after applying that way worked for me. Perhaps there could be something wrong with line endings or something with the file...

Glad the URL works instead though, that's probably a better way to apply the patch anyways.
