PfSense Dynamic DNS configuration for he.net

mdpugh · Jan 19, 2012, 8:26 PM

Has anyone set up Dynamic DNS in pfSense 2.0.1 for he.net (standard IPv4 DNS, not the tunnelbroker)? I've tried every combination of username and password (those I use to log onto he.net and the <domain>.com and MD5 hash generated from the DDNS column of the Free DNS Management page). I've tried each combination with and without the wildcard enabled since I found info in the dns.he.net forum that wildcards have been disabled. In every case I get 0.0.0.0 showing in red for the Cached IP. An excerpt from the system log shows:

Any idea what I'm doing wrong?

Nobody? With as many people who are evidently using HE for IPv6 access, it's hard to believe no one has helped themselves to their free DNS. I certainly would like to know how to configure Dynamic DNS for dns.he.net.

https://dns.he.net/ says "Dynamic DNS - We're leaving this down here until we're happy with it ;)" I wonder what that means.

Oh man, this is an old post, but I hope I'm not too late!

The way it works is simple, you enable dynamic dns on the HE interface and then you generate a DDNS Key that will become your password. Then in pfSense use the complete dynamic hostname like foo.example.com in both hostname and username.

it is seem still no normal work.

I configured it exactly as you said, but I could never get it to work either. I switched to static addresses so it's no longer an issue.

what's do you mean? what's switched to static addresses? we should talk about the dns.he.net,right now?

mdpugh · Apr 22, 2012, 2:58 PM

To clarify: I configured my system as MageMinds suggests (although I did so long before after following instructions posted by someone in the he.net dns forum). It still did not work for me. I had been meaning to switch to static public IP addresses anyway and the time seemed to have arrived. I no longer have dynamically configured addresses so I don't have to continually update the DNS servers at he.net. Surely, that is self-explanatory.

To anyone else seeing the curl error, this is what I have found.

The curl error is related to this bug http://curl.haxx.se/mail/tracker-2010-12/0008.html, basically curl is trying to bind an ipv6 address on an ipv4 interface. My first thought was to add the curl ipv4 option to the script, but it seems that this option is missing in PHP 5.2 https://bugs.php.net/bug.php?id=47739. What worked for me, since I was running the DNS forwarder anyway, was to add just the ipv4 address for dns.he.net to the host overrides in the DNS forwarder. You should be able to accomplish the same thing by adding this to your hosts file but I haven't tested that.

I have to find two solution. I have test these solution. :)

edit /var/etc/hosts file or edit the /etc/inc/dyndns.class file.

change dyndns.class file to:

case 'he-net':
$needsIP = FALSE;
log_error("HE.net: DNS update() starting.");
$server = "https://ipv4.dyn.dns.he.net/nic/update?";
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERPWD, $this->_dnsHost . ':' . $this->_dnsPass);
curl_setopt($ch, CURLOPT_URL, $server . 'hostname=' . $this->_dnsHost);
break;

or just edit hosts file add:

184.105.242.3 dyn.dns.he.net
