DynDNS was always the dynamic IP service of choice, but I could never get it to work properly, and I was always stuck with their lame domain names as I’m too cheap to pay for their serivces.
Luckily services of all kinds, including DNS Providers, have caught on to the fact that people want API’s. If there’s an API to do DNS updates, I can script a solution.
1 2 3 4 5 6 7 8 9 10 11 12 #!/bin/bash curl https://www.cloudflare.com/api_json.html \ -d 'a=rec_edit' \ -d 'tkn=1234512345qweqwe1234512345' \ -d 'id=12345' \ -d [email protected]' \ -d 'z=jrgns.net' \ -d 'type=A' \ -d 'name=home' \ -d "content=$1" \ -d 'service_mode=0' \ -d 'ttl=3600'
Quick and dirty. This updates a domain (home.jrgns.net) with id 12345 with the
IP address that’s passed as the first argument to the script. There’s a bunch of
ways to get your external IP, my favourite is
but I just run this script as the
postscript of my ddclient (which updates another
1 2 3 4 5 6 7 8 9 10 # /etc/ddclient.conf protocol=dyndns2 use=web, web=myip.dnsomatic.com ssl=yes server=updates.someservice.com [email protected] password='123456' daemon=3600 postscript=/home/jrgns/bin/cloudflare_dynamic_dns.sh
I’m sure the same can be done with outer services such as Route 53? Has anyone tried something like this?
