This script was intended to be able to use vultr firewall and block all IPs and only whitelist your own IP.
because vultr don't accept a dynamic DDNS domain (like no-ip)
This script will update vultr with your new ip every time it changes
for example i have a freepbx server running in vultr so i set a firewall to only allow my location to access the server
Assuming you have a vultr account (if you dont have one you can use my affiliate link and Get $100 for the first 30 days)
- go to the firewall tab, and click 'Add Firewall Group'
- select the protocol you would like to open for yourself like TCP
- enter the port or range for example
1 - 65535 - select one source the ip (not important as the script will update it
- IMPORTANT, add a any word as a note to your rule, so the api can find it, for example i use my username
mbrctv
api_key vultr api key
firewallgroup the firewall ID
notes the note you added for reference
ddns_domain (Optional) the ddns domain if you have
smtp_server (Optional, defaults to gmail)
user (Optional, defaults to from_email) username passed in smtp server authentication
password (Optional) smtp server password
from_email (Optional) if you want email notification each time the IP changed
to_email (Optional) array of emails (can be array with only 1 email)
from_name (Optional) sender name
you can set api_key as global, or set it for each firewall rule
you can set email or in global or for each firewall
To loop forever with a configurable delay between polls edit ddns.py and set loop_forever to True. The delay time is configurable,
defaulting to 60 seconds.
Create a task in Task Scheduler to run every 30 minutes. Follow the Microsoft guide for basic task creation.
Open Task Scheduler and click "Create Task...". Give it a name and create a new trigger. Click "Daily". Under "Advanced Settings" click to repeat the task every 30 minutes and change "for a duration of" to "Indefinitely". Add a new action to start a program and browse to your Python executable. Add the ddns.py script as an argument.
