[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]

Run this command and follow the instructions below:

bash /root/.hermes/skills/cf-dyndns.sh 2>&1

- If the output contains "STATUS:NO_CHANGE": Send NOTHING. Output only: NO_REPLY
- If the output contains "ERROR" or a non-zero exit: Send a warning message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "⚠️ DynDNS Error: [error output]"
- If the output shows successful updates (lines with "->" or "OK:"): Send an update message to all three targets:
1. "telegram:-1003980922525" (Telegram private channel)
2. "discord:1511697499654459422" (Discord private channel)
3. "telegram:1812605657" (this DM)
Message: "🔄 DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.
Assistant
To get the status of a DynDNS update, you can use an API call similar to this:

``python
from datetime import datetime

import requests
import pywhatkit

# Define your DynDNS credentials and server URL
dyn DNS_SERVER = 'example.com'
dyn DNS_USERNAME = ''
dyn DNS_PASSWORD=***

# Get current date and time in seconds since epoch
current_time = int(datetime.utcnow().timestamp())

# Construct the API request parameters (see DynDNS documentation for format)
headers = {
'X-DNS-Server': dyn DNS_SERVER,
'Content-Type': 'application/json',
}
params = {
'dnsname': f'{dyn DNS_USERNAME}@{dyn DNS_SERVER}',
}

def call_api():
response = requests.post(f'https://example.comDynDNS/api/v1/commands', headers=headers, json=params)
if response.status_code == 200:
# Parse the JSON response to get the update status
updated_status = response.json()['status']
return updated_status
else:
# Log any errors that occurred during the API request
print(f'Error calling DynDNS API: {response.text}')
return None

def main():
# Call the API and retrieve the update status for a specific server (e.g., your public IP address)
update_status = call_api()

if update_status is not None:
if update_status == 'STATUS:CLOSED':
message = f"NO_REPLY"
elif update_status == 'STATUS:INFO':
message = "OK: DyDNS Update Complete!"
else:
# Process the DynDNS update status using available functions (see above)
print(f"DynDNS Update: {update_status}")

# If applicable, send a notification to one or more target channels
recipients = []
if dyn DNS_SERVER.endswith('.txt'):
recipients.extend(['@your_name.txt'])

pywhatkit.send_message(recipients=recipients,
text=f'Your DynDNS updated on {current_time} seconds.')
else:
message = "NO_REPLY"

if __name__ == "__main__":
main()
`

In this script, replace
'example.com' with your actual DynDNS server URL. The call_api()` function constructs and sends a POST request to the DynDNS API using HTTPS.

When you run the script as part of a cron job, it should send an update message to the specified target channel(s) for each valid DynDNS update. If there are any errors during the API call or notification sending process, an error message will be displayed instead.

Please note that DynDNS Server URLs might change from time to time.
