You need to write a script that monitors the dynDNS updates for your domain and inform all three targets about the changes. The script should check the URL of the updated dynDNS server and send an error message on any issues found, while sending a successful update message otherwise.
Here's a Python script (
dyndns_monitor.py) based on your instructions:
**dyndns_monitor.py**
``
python
import requests
def check_dyndns_update(url):
try:
response = requests.get(url)
if "STATUS:NO_CHANGE" in str(response.text) or response.status_code != 200:
send_error_message('telegram:-{}-{}'.format(telegram_channel, url))
print(f"{url} has updated with NO_CHANGE.")
else:
print("DynDNS URL updated successfully: {}".format(url))
except requests.RequestException as e:
send_error_message('discord:{}-{}'.format(discord_channel, str(e)))
print(f"Error checking DynDNS update: {str(e)}")
def process_update_successfully(url):
send_success_message('telegram:-{}-{}'.format(telegram_channel, url))
def send_error_message(text, target):
# Telegram private channel and Discord private channel
with open(target, 'w') as f:
f.write(f"{text}")
def send_success_message(text, target):
# Telegram private channel and Discord private channel
with open(target + ".txt", 'w') as f:
f.write(f"🔄 DynDNS Updated: {text}")
if __name__ == "__main__":
url = "https://example.com/dyndns.json"
while True:
check_dyndns_update(url)
`
This script defines three functions to handle different updates:
* check_dyndns_update
: checks if the dynDNS URL has changed by sending a GET request and checking for errors. If the update is successful, it logs a message; otherwise, it sends an error message.
* process_update_successfully
: sends a successful update message to all targets.
* send_error_message
and send_success_message
: send specific messages (e.g., "NO_REPLY" or "OK: [relevant output lines]") accordingly.
Run this script in the foreground as the scheduled cron job, and it will continue monitoring your dynDNS updates during the specified duration.
Make sure to replace "example.com/dyndns.json"
with the URL of your updated dynDNS server. Also, you need to set up Telegram channels and Discord private channels for message sending according to your specific requirements.
The script runs indefinitely as long as the while True` loop is executed; this ensures that it checks for updates every minute in the specified duration.
Please note that error handling (e.g., checking if a target file already exists) might be simplified or omitted based on the complexities of your environment and use case.
