Gandi LiveDNS v5 as DynDNS provider

This is just a simple curl command to put in your crontab that updates some domain managed by Gandi LiveDNS v5. The reason behind this is that while DDclient has a PR that enables Gandi support, the project itself doesn't seem to be actively maintained anymore (see recent issues).

Replace the domain and API key with your own ones and put the following into your cron file:

curl -d "{\"items\":[{\"rrset_type\": \"A\", \"rrset_values\": [\"$(dig +short myip.opendns.com @resolver1.opendns.com)\"]}]}" -X PUT -H "Authorization: Apikey REDACTEDAPIKEY" -H "Content-Type: application/json" https://api.gandi.net/v5/livedns/domains/example.com/records/foobar > /root/last_dyndns_out.txt 

The current configuration uses REDACTEDAPIKEY to change foobar.example.com to the IP address obtained by a DNS request to myip.opendns.com. Make sure you have dig installed!

Optionally, pipe the output into some file you check regularily, into a logging system, or Email it automatically.
