Dynamic DNS support for Gandi LiveDNS?

Antimatter47

Hello,

Gandi.net supports updating DNS records using their API, both on their old DNS platform and their new LiveDNS platform. Would it be possible to support this in pfSense's dynamic DNS feature? A quick search found a few scripts that are supposed to do this for LiveDNS:

https://github.com/Gandi/api-examples/blob/master/bash/livedns/mywanip.sh
https://github.com/cavebeat/gandi-live-dns
https://github.com/plut0nium/gandi-dynamic-livedns
https://github.com/rmarchant/gandi-ddns

Alternatively, I have very limited scripting and command line skills, but how realistic would it be to run one of these scripts on a pfSense machine, using whatever mechanism it is that triggers pfSense's built-in dynamic DNS clients to perform an update, to trigger the custom script?

Thanks!

I am using this script with a cron entry.


0 	* 	* 	* 	* 	root 	/usr/local/bin/gandi.sh

I had to install bash since it doesnt come with FreeBSD. The downside is that it is not linked to WAN. You may want to look at this.

–---------------------------------------------------------------------------------
Second approach was to run nginx/php on a separate FreeBSD server. The script i used were


$cat /usr/local/bin/mywanip4.sh

#!/usr/local/bin/bash

DOMAIN="mydomain.com"
RECORD="myrecord"
APIKEY="MYKEY"

API="https://dns.api.gandi.net/api/v5/"

IP4=$1

if [[ -z "$IP4"  ]]; then
    echo "Something went wrong. Can not get your IP from WAN "
    exit 1
fi

if [[ ! -z "$IP4" ]]; then
    DATA='{"rrset_values": ["'$IP4'"]}'
    curl -s -XPUT -d "$DATA" \
        -H"X-Api-Key: $APIKEY" \
        -H"Content-Type: application/json" \
        "$API/domains/$DOMAIN/records/$RECORD/A"
fi

# cat /usr/local/www/nginx/gandi_update.php 
   if(isset($_GET['ip']) && filter_var($_GET['ip'], FILTER_VALIDATE_IP))
   {
      $output = shell_exec('./mywanip4.sh ' . $_GET['ip']);
      echo "OK";
   }
   else
      echo "FAIL";
?>

I had to install php56-filter and bash packages on the FreeBSD server to make it work. The update URL was http://192.16.1.2/gandi_update.php?ip=%IP%

I have added Gandi LiveDNS as a Dynamic DNS Client.
