[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.

Here's a simplified version of your command and the corresponding Python code:

``python
import subprocess
import time

def run_command(command, target):
try:
output = subprocess.check_output(command, shell=True)
print(output.decode('utf-8'))

except subprocess.CalledProcessError as e:
print(f"[ERROR] {target}: {subprocess.output(e.stdout)}")
except Exception as e:
print(f"[ERROR] {target}: Invalid command")

time.sleep(1) # Introduce a small delay to avoid flooding the output

# Run the given command and specify the targets
run_command(["sh", "/root/.hermes/skills/cf-dyndns.sh"], "telegram:-1003980922525, discord:1511697499654459422")
`

However, this approach has some limitations:
- The Python script can get stuck if another process uses it while the command is running.
- It doesn't provide any error handling or notification for successful updates from DynDNS.

To mitigate these issues, you might want to use a service like
supervisor (to be installed via PyPI and pip install supervisord).

Here's an example using
supervisor.py:

`python
import subprocess
import time

def run_command(command, server, port):
stdin = f"start -t {port} {command}"
supervisor.start("dyndns", ['python3', '-u dyndns_manager.py', server])

run_command(["sh", "/root/.hermes/skills/cf-dyndns.sh"], "telegram:-1003980922525, discord:1511697499654459422")
`

Remember to install
supervisor before running the script.

To check DynDNS status for successful updates:

`python
import subprocess

def update_dyndns_status(host):
try:
output = subprocess.check_output(["ps", "-ef", host], shell=True)

if "OK" in str(output).strip():
print(f"\n{host}: Updating {time.ctime()} OK")

except Exception as e:
print(f"[ERROR] Update from {host}: {e}")
