PynamicDNS

Python script to perform dynamic DNS using AWS Route53 on a Raspberry Pi or other Linux hosts

See this post at tynick.com for full instructions.

Run Manually

You can run the script manually to test.

It will look something like the following if your public IP doesn't match your DNS record...

root@raspberrypi:~# python3 ~/PynamicDNS/PynamicDNS.py pynamicdns.tynick.com X0XXXXXX000X0
---------------------------
Public IP:             xx.xx.xx.xx
pynamicdns.tynick.com: yy.yy.yy.yy
---------------------------
DNS VALUE DOES NOT MATCH PUBLIC IP
DNS CHANGE SUCCESSFUL
root@raspberrypi:~#

pynamicdns.tynick.com: xx.xx.xx.xx

NO CHANGE NEEDED

Run Via Cron

Once you confirm that it is working, you'll want to make a new cronjob so that it checks your IP every 5 minutes.
