[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.

To run this command, you'll need to connect your Hermes instance as a cron job user and make an API request to the cf-dyndns.sh script that updates dynamic DNS records.

Here's how you can do it:

1. Log in to the Hermes API management interface as a cron job user.
2. Click on "Applications" in the top menu, then select "Add new application".
3. Fill in the required details for your application, such as the name and description.
4. In the "Code" or "Script" field, enter the path to your cf-dyndns.sh script file.

The script runs every 2 minutes, and it updates the dynamic DNS records associated with each of your servers.

Here's an example of what the API request might look like:

``bash
curl -X POST \
https://your-hermes-instance.com/v1/apps/your-app-name/applications/0/dynamic-dns \
-H 'accept: application/json' \
-H 'Authorization: Hermes-Secret-Key' \
-d '{"dynamic_dns_records": [{"server_id": "...", "record_name": "..."}, {...}]}'
`

Replace
your-hermes-instance.com with your actual Hermes instance URL, your-app-name with the name of your application, and Your-Hermes-Secret-Key with a valid secret key for your API.

Once you've made the API request, the script will run, updating any relevant dynamic DNS records.

Note: This example assumes that you're logging in to the Hermes instance using an SSH connection as the cron job user. If you're using another authentication method (e.g., OAuth or SSO), you'll need to modify the
Authorization` header accordingly.

Also, keep in mind that updates to dynamic DNS records can have significant performance implications for your servers and users, so make sure to monitor any changes carefully and adjust your systems as needed.
