[IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user โ€” 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 โ€” 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: "โš ๏ธ 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: "๐Ÿ”„ DynDNS Updated: [relevant output lines]"
- Never send routine "no change" notices.

You want me to write a script that will perform the following tasks when run as a scheduled cron job:

1. Check the status of DynDNS servers.
2. Send notifications if there are any errors or changes in status.
3. Send updates with specific messages for each notified target.

To accomplish this, I would need to see the script that you're using. However, based on the provided information and the options mentioned (Sending a silent message with only "NOReply" and sending multiple different types of notifications), here is an example python script:

``python
import subprocess

# Define DynDNS commands for each target
telgrind_telegram = [
# Telegram private channel
f'Telgrind {substr} Telegram -d {status} |',
subbed_string={}
]

discord_target = {
'token' : 'token',
}

threading.Thread(target=logging.error, args=("DynDNS Error: *"), daemon=True).start()

def run_dyndns_commands():
# Check if DynDNS servers are up
try:
subprocess.check_call(['telgrind_telegram'][0],
f'Telgrind {mailgun_url}, -d {status}',
subbed_string={})
except subprocess.CalledProcessError as e:
print(f"DynDNS Error: {e}")
return False

# Send notifications if there are any errors or changes in status
threading.Thread(target=logging.warning, args=("DynDNS Updated:", discord_target)).start()

# Send update messages with specific target names
# and notification data
threading.Thread(target=logging.update, args=(mailgun_url,)).start()

return True

if __name__ == '__main__':
while run_dyndns_commands():
pass
`
Please make sure to provide your
mailgun_url` when creating the cron job.
