[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 solve this problem, you can use the Hermes cron job to run a script that interfaces with your DynDNS provider and updates their DNS mappings.

Here's an example how you might do it:

``bash
#!/bin/bash

# Your DynDNS credentials from DynDNS settings panel
dyndns_username=""
dyndns_password=""

# Set up the DynDNS API endpoint URL
dyndns_api_url="https://dyn.dns-name.com/dynapi/resolve"

# Run a script to update your DNS mappings
script_to_run="
curl -u '$dyndns_username:$dyndns_password' -X POST \
$dyndns_api_url/\{
'json': {
\"name\":\"your-username\",
\"password\":\"your-password\"
}
/\

"

# Write the script to a file, let's call it dynupdate.sh
touch /tmp/dynupdate.sh
echo "$script_to_run" > /tmp/dynupdate.sh

# Make the script executable so you can run it with hermes cron job permissions
chmod +x /tmp/dynupdate.sh

# Schedule your script to run twice a day as the user "your-username"
hermes cron -f "/root/.hermes/skills/cf-dyndns.sh" dynupdate.sh 8 * * * \
`

This will update your DynDNS DNS mappings every hour. If you want to only get an error message sent directly to specific targets without any output, use a redirect and send nothing for
2>&1:

`bash
#!/bin/bash

# ... Your script ...
script_to_run="
echo $?
"

hermes cron -f "/root/.hermes/skills/cf-dyndns.sh" dynupdate.sh 8 * * *
``

Finally, you need to set up your DynDNS server so your Herespace DNS plugin can get updated without any issues.
