[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 analyze the status of DYNDNS (Dynamic DNS), you would typically use this command, where 'YOUR_DYNDNS_IP' is your DynDNS server IP and 'YOUR_ZONE_NAME' is the name of your website.

``python
import subprocess

def check_dyndns_status(server_ip, zone_name):
# Check if status changed successfully
output = subprocess.check_output(['your_command_here', f"statusNOCHANGE {server_ip} {zone_name}"], stderr=subprocess.STDOUT)

if "STATUS:NO_CHANGE" in str(output):
return False
else:
return True

# Usage example with Telegram
tgbot_key = "YOUR_TELEGRAM_KEY"
tgbot_token = "YOUR_TELEGRAM_TOKEN"

server_ip = "YOUR_DYNDNS_SERVER_IP"
zone_name = "YOUR_ZONE_NAME"

if check_dyndns_status(server_ip, zone_name):
print(f"DynDNS updated: Successful")
else:
print(" DynDNS updated: No Change")

# Usage example with Discord
discord_bot_key = "YOUR_discord_BOT_KEY"
discord_token = "YOUR_discord_BOT_TOKEN"

server_ip = "YOUR_DYNDNS_SERVER_IP"
zone_name = "YOUR_ZONE_NAME"

if check_dyndns_status(server_ip, zone_name):
print(f"DynDNS updated: Successful")
else:
print(" DynDNS updated: No Change")

# Usage example for silent delivery
try:
subprocess.check_output(['your_command_here', f"statusNOCHANGE {server_ip} {zone_name}'], stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as error:
if "ERROR" in str(error):
print(" DynDNS updated: No Change")
`

Replace the placeholders (
YOUR_DYNDNS_SERVER_IP, YOUR_ZONE_NAME, etc.) with your actual server IP, zone name, and Telegram bot key/discord bot token. Make sure to run these commands as a cron job or scheduler if you're not familiar with how they handle output and errors.

For silent delivery or when you don't care about the actual status of DynDNS, the [try-except-catch-missone-otherwise](https://en.wikipedia.org/wiki/Errno) block will catch the exceptions raised by
subprocess.check_output instead of the command itself, in case any of them fail.

Here's a brief note on error handling:
1. The command outputs will not be cached; each run may return different results.
2. If an exception is raised (like a syntax error or permission denied), the catch block will try to continue without showing the specific output related to the error.

While this approach works well for many tasks, remember that using
try-except` blocks can sometimes lead to less informative error messages. In these situations where you require more detailed logs and want to know whether an operation failed or timed out, consider setting up logging before sending commands.
