[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
This task is a simple cron job script that runs in the background and updates a dyn DNS service remotely.

To create this script, you would need to:

1. Create a new file called cf-dyndns.sh in your .hermes/skills directory (this is where Hermes' skills are located). You can do this by running touch .hermes/skills/cf-dyndns.sh and then copying the following contents into it:

``bash
#!/bin/bash

# dyn dns update script for hermes

# Set the server you want to update
SERVER="dyn1.dynvhost.com"

# Set your username and password for auth (only needed if using SSH)
USERNAME="username"
PASSWORD="***".

# Check if the dyn dns server is running and running successfully
while true; do
# Get the status of the dyn dns service
response=$(ssh -o "StrictHostKeyChecking=no" $USERNAME@$SERVER check DynDNS")

# If the dyn dns service was not found, send an alert to all targets
if [ "$response" == "ERROR" ]; then
echo "Dyn DNS Error: $response"

# Send a warning message to all three targets
Targets=(" telegram:-1003980922525" "discord:1511697499654459422" "telegram:1812605657")
for target in "${ Targets[@]}"; do
if [ -n "$target" ]; then
echo "⚠️ DynDNS Error: $response"
fi
done

# Send an update message to all three targets
TargetMessage=""
Targets=(" telegram:-1003980922525") # Only send the DM as a target once per error
for target in "${Targets[@]}"; do
if [ -n "$target" ]; then
echo "DynDNS Updated: $response"
TargetMessage+=" Dyn DNS Updated: $response\r\n"
fi
done

echo ""

# Wait 1 minute before checking again
sleep 60
done
`

2. Make the script executable with
chmod +x cf-dyndns.sh.
3. Trigger the update using the provided
cf-dyndns.sh script in your cron job, as shown above.

Note: Make sure to replace
"dyn1.dynvhost.com" and "username"` with your actual dyn dns server details.
