[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 write to the cf-dyndns.json file and receive updates on successful or failed dynDDNS operations, you can use the following command:

``bash
sudo python /root/.hermes/cf-cron/dyndns.py 2>&1 && [ "$?" -eq 0 ]
`

This command will run the
cf-dyndns.py script every two seconds and check for updates on successful or failed dynDDNS operations. It will send an update notification if successful, and a warning message with error messages.

Here is how to implement this in your scheduler:

1. Create a file
/root/.hermes/cron/dyndns.py (or any file of your choice).

This script should read
cf-dyndns.json from the Hermes server location: [Your_Hermes_URL]/dynDNS/config/. Here's an example implementation:
`bash
#!/bin/bash

cd "$(dirname "$0")"
read -p "Enter DynDNS username: " username
read -p "Enter DynDNS password: " password
read -p "Enter DynDDNS server hostname: " hostname
if [ ! -f "/root/.hermes/cron/dyndns.json" ]; then
cat > "/root/.hermes/cron/dyndns.json"
fi

echo "{\"status\": \"success\", \"data\": \"$cf-dyndns.\$username.$cf-dyndns.service\","} >> /root/.hermes/cron/dyndns.json
`

2. Create a
cron file at /etc/ cron.d/ (or any location of your choice).

3. Add the following line to the end:
`bash
* * * * * python /root/.hermes/cron/dyndns.py 2>&1 && [ "$?" -eq 0 ]
``

Your schedule should be ready now! This will continue to run and send updates on successful or failed dynDDNS operations.
