You would write the following Python script to fetch and update the DynDNS info:
``
python
def fetch_and_update_dyndns():
# Update your dynDNS settings as needed (e.g., dns-server, port)
print("Updating dynDNS settings...")
dyndns_output = (
""" STATUS: NO_CHANGE
Error message:
`
You can replace the text between """ and "\"
with a real error message if you need it. This tells DynDNS to output "STATUS:NO_CHANGE" instead of logging an incorrect status.
Please make sure you have the necessary permissions to access yourDynDNS settings on your target device(s).
Next, you would call this function whenever you want your dynDNS info updated:
`
python
if __name__ == '__main__':
fetch_and_update_dyndns()
`
Do not run this script inside a cron job. Instead, it should be part of a scheduled task to check the DynDNS status once an hour for up-to-date information.
Note: The commands provided only update one target with "OK:", and do not send any reply or notification messages that other targets might rely on as their own notifications.
For your second requirement, here is a sample Python script using requests
library:
`
python
import requests
def check_status(target):
try:
response = requests.get(f'http://{target}/status')
return response.text.strip()
except requests.exceptions.RequestException as e:
print(f"Failed to fetch the dyndns info: {e}")
if "no change" not in [line.lower() for line in response.text.split('\n')]:
raise
targets = ["www DynDNS.com", "tele2 DynDNS.de"]
for target in targets:
check_status(target)
``
You can run this script once an hour using celery or any other task queue to fetch the status.
Make sure you have the necessary permissions to access your DynDNS settings on your target device(s).
