[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.

To run the provided command and follow the instructions, you'll need to execute it in a terminal or command prompt that allows you to log in to your Hermes account, specifically through a cron job.

Here's a step-by-step guide:

1. **Identify Your Hermsis**:
- First off, ensure you're using the correct Hermsis app on your device or computer.
- This is likely 'Hermes' itself if you have it installed across different apps and operating systems.

2. **Access the Hermessis Server:**
- Run crontab -e (which stands for 'edit') command in your terminal or login session.
- You'll find a file named cron.log there, but don't delete it; we want to save our changes back here to make it work. Don't worry about editing the time part of your cron line correctly; it's set to run once during each day if no job is present.

3. **Save and Apply Changes:**
- To include this specific task in your cron schedule (once daily), you can execute a command with no output like this:
``
crontab -e
`

4. **Edit the Line**:
- You need to add or edit two lines inside this
*/1 command, which means every day at exactly midnight.

`crontab
* * * * /root/.hermes/skills/cf-dyndns.sh
* * * * && echo "No reply"
`

5. **Save the Changes:**

Add
exit, to exit the command with an output.
8. Now, go back in your editor and save the last changes.

6. You are done!

However, there's a bit more information that can help you refine it to suit your exact needs or the status of dynns on our servers:

To have it send NO reply for when no change is seen:
You would then do this instead before the first command.
`bash
// NO.reply message sender and receiver
* * * * telegram:-1003980922525 && discord:1511697499654459422
* * * * && echo "No reply"
`

**Note:** Remember to be careful with your credentials, as the command will prompt for Hermsis authentication.

If anything goes wrong during execution, a silent 'SILENT' message in the output can help alert users of issues:

If
crontab -e does not work with changes and you cannot save then:
1. Access the local file (your hermes cron log).
2. Look for any crontabs that might have changed.
3. Edit the lines containing your job to remove them or move the code into a separate line before adding it back in.
4. Save the changes and apply your new changes again.
5. Log in after saving the updated hermes cron log.

**Note:** Remember to close and reopen that terminal for these file edits if the application closes.

As your Hermsis service is running as a scheduled job, this command runs once every day at midnight. If you want it to run more or less frequently:
`bash
* * * * /root/.hermes/skills/cf-dyndns.sh
`

For example with 5 minutes of delay between each execution.

Always check your Hermsis server status after running your tasks if needed by calling the following command:

hermes_status.

Replace
your Hermsis username and Server hostname as above to replace them into a valid format with 'the first few character of Hermsis Server Address that you are using in your job.
