Custom Dynamic DNS
-
Yes i would like the same thing, I use EveryDNS as a service (http://www.everydns.com/) and would like pfsense to do the updating…
thanks

If they publish an API or some kind of spec on doing remote updates, it might be possible.
I added support for namecheap.com's DynDNS a week or two ago and it didn't take much, but they used a different API than any other DynDNS provider we had.
Given the vast differences in how providers update, I doubt any generic method would be feasible and reliable.
EDIT: Looks like everydns wouldn't be too hard to add, based on http://www.everydns.com/eDNS.pl - someone could probably work similar code into our dyndns.class without too much effort.
-
Yes, you are correct that there are vast differences in how providers update, however they all follow a fairly common set of rules.
Usually something like send a request to URL "http://provider/update.php?username=un&password=Pa$$Key&ip=" then simply add the ip to the end and call fetch or php's http_get. The results shouldn't be too hard to generate rules for. Usually something very constant with maybe a date, or IP.
It really shouldn't be that hard to code, I might try to write something this weekend if I have time. -
Some do, yes. But their return codes vary wildly not only in text but also how they are delivered, and part of properly functioning dyndns updates is being able to detect successful updates and error conditions.
So it might be doable, but it would require a bit of work to make sure it worked properly. :-)

Absolutely, but limited support is better than none.
I see nothing wrong with simply making the user enter a string like "IP Updated to: %IP" and check that the output exactly matches that string and the return code is 200, other wise assume a problem, log it and try again in a couple of minutes. -
The way I see it there are two easy ways to implement support for Custom DNS:
1. Write it into the current Dyndns scripts in pfSense.
2. Use a prebuild dyndns program like http://www.inatech.eu/inadyn/: The one used by DD-WRT Firmwares to include custom dns.Although I think option 1 is a much better option, option 2 might allow for better support. Some (few) DDNS Providers support DD-WRT and have instructions on how to add it, and using the same program would guarantee that the same configuration will work.
I wouldn't mind doing option 1, but it might take me a while to get around to it. -
Doing it in pfSense may not be that hard - the code for dyndns isn't that hard to get around, it's easy to copy/paste and adjust.
Adding some GUI bits for a "custom" option wouldn't be too difficult for someone who knows PHP, HTML and JavaScript.

In that case, I'll go ahead and start working on it, though I might not have much time in the next week, so it might be a while before I can get around to finishing it.
-
Sure. Most of the code you'd need to look at is in /etc/inc/dyndns.class and /usr/local/www/services_dyndns.php
-
The attached patches work, although the GUI could be done a bit nicer.
Just```
patch -R /usr/local/www/services_dyndns.php < services_dyndns.php.txt
patch -R /usr/local/www/services_dyndns_edit.php < services_dyndns_edit.php.txt
patch -R /etc/inc/dyndns.class < dyndns.class.txt
patch -R /etc/inc/services.inc < services.inc.txtNotes: Currently, the cache file used is {$g['conf_path']}/dyndns_{$dyndns['interface']}{$dyndns['type']}.cache, which will result in a shared cache file for any two DDNS settings on the same provider, this might cause problems for people with multiple Custom Entries. The GUI of the current version states that freeDNS does not require a username, but the script currently requires it. Can someone with experience with freeDNS comment as to whether or not freeDNS requires a username. dyndns.class does not currently check that the server returned a sensible HTTP Status, only that the match string is equal. Also, it would be nice to eventually allow multiple match strings.

Version 2:
Much better GUI, and multiple match strings.
Patches now go the right direction, so just install the patches with```
patch /usr/local/www/services_dyndns.php < services_dyndns.php.txt
patch /usr/local/www/services_dyndns_edit.php < services_dyndns_edit.php.txt
patch /etc/inc/dyndns.class < dyndns.class.txt
patch /etc/inc/services.inc < services.inc.txtTested to work with tunnelbroker.net on the latest snapshot.

I haven't had a chance to test this (been a busy day) but it looks promising.
You could get the ID of the dyndns instance and append that to the name after the dyndns type perhaps, to make it more precise.
-
Version 3:
Allows for custom script execution on update failure,
Allows for requests to originate from an interface other than the one monitored (useful to call LAN scripts on update),
Uses a unique id in cache and debug files.Once again patch with```
patch /usr/local/www/services_dyndns.php < services_dyndns.php.txt
patch /usr/local/www/services_dyndns_edit.php < services_dyndns_edit.php.txt
patch /etc/inc/dyndns.class < dyndns.class.txt
patch /etc/inc/services.inc < services.inc.txtIssues: The GUI of the current version states that freeDNS does not require a username, but the script currently requires it. Can someone with experience with freeDNS comment as to whether or not freeDNS requires a username. dyndns.class does not currently check that the server returned a sensible HTTP Status, only that the match string is equal. When an entry is deleted, the script rechecks all interfaces and removes all cache files, it should gracefully move all cache files to the appropriate new ID number.

I do not agree totally with this patches and will make some modifications of them: -
Have fun do what you want - I do not claim any copyright to the above patches.

Hi!
While you are modifying the DDNS behavior, is it possible to add OpenVPN as an interface? I am using OpenVPN as a Client, and I am routing all my traffic through a public VPN provider. I am solving the DDNS issue now by using the DynDNS client on a server connected to the LAN, but of course, the ideal thing is to use pfSense for this.Thanks!
-
Zappca,
Have you tried assigning your openvpn instance as an OPT interface? (assign it, enable it, select "none" for the IP type)
It may do what you want then.
-
Unfortunatly it does not. I tried assigning the interface to the ovpnc1 port, but the DNS client was not able to retrieve the IP adress that OpenVPN was connected to. The adress reported back was 0.0.0.0.
-
Then it may be covered by the changes I've suggested here: http://redmine.pfsense.org/issues/904
May not happen for 2.0 though.
-
I've updated the patches to fix a couple bugs I've been seeing on the previous patches.
1. Because of the lines```
if (!empty($int))
break;in services.inc, only one dyndns provider will be updated per interface if services_dyndns_configure is called with an interface (it usually is), this is a bug in pfSense, and is unrelated to my particular patch, but effects all users of multiple dyndns providers on one interface (or should as far as I can tell). 2\. One of my providers automatically pings my IP Address to make sure it is up before allowing updating (tunnelbroker.net) thus /etc/inc/interfaces.inc had to be changed to allow filter_configure to happen before serivces_dyndns_configure. I added a sleep(1) to make sure the reload is done. All other previous issues still apply. Zappza: I don't use OpenVPN on my installation, so I don't know how pfSense handles the interfaces of it. If you could send an output of ifconfig -a (or at least the relevant parts) and the list of interfaces according to the webUI, I'll try to add it if I have time. New Patches are attached and can be applied through``` patch /usr/local/www/services_dyndns.php < services_dyndns.php.txt patch /usr/local/www/services_dyndns_edit.php < services_dyndns_edit.php.txt patch /etc/inc/dyndns.class < dyndns.class.txt patch /etc/inc/services.inc < services.inc.txt patch /etc/inc/interfaces.inc < interfaces.inc.txtAgain, I claim no copyright on the above patches, or anything posted previously.
