User
[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.

The code snippet appears to be related to managing and maintaining Dynamic DNS (DDNS) servers using Hermes, a popular command-line tool for managing network services. The specific task is to update the DDNS settings in multiple destinations (targets). Here's a step-by-step breakdown of what you need to do based on the provided code:
1. **Identify the targets:** First, find out which targets have been updated. In this case, it seems to be happening for three different channels: Telegram (:-1003980922525), Discord (1511697499654459422), and your personal DM channel (1812605657). Keep note of these IDs.
2. **Test the output:** Run the provided cron job cf-dyndns.sh 2>&1, which will execute the script in background, and then wait for it to finish (you can see this using pkill -f cf-dyndns.sh).
3. **Check for errors or non-zero exit codes:**
* If you run into "ERROR" or a non-zero exit code:
+ Send an update message with a warning to the affected targets (Telegram, Discord, and DM) along with your report of the error message ⚠️ DynDNS Error: [error output] in each channel.
* If there is successful updating without errors (* -> OK) as seen in lines like "->OK:":)
+ Send an update message with "🔄 DynDNS Updated" only to the affected targets (Telegram, Discord).
4. **Never send the standard "no change" notice.**
Here is a modified version of the command that checks for errors and sends updates manually.
``bash
#!/bin/bash
# Output directory in case error occurs or exit due to failure
OUTPUT_DIR="/var/hermes/output"
# Execute the script with argument 2>&1 (output from command executed)
if [ $? -ne 0 ]; then
echo "ERROR: Execution finished with non-zero return code $?"
fi
# The original script was:
# bash /root/.hermes/skills/cf-dyndns.sh # Note that execute instead of runbash
# Run the script directly in background using -jn option & (Note note the correction)
# We're checking for no errors to prevent sending out messages.
execute cf-dyndns.sh 2>&1
if [ $? -ne 0 ]; then
echo "ERROR: Execution finished with non-zero return code $@"
else
# Only send updates if there were successful modifications or commands ran which didn't result in failure.
# Update Telegram, Discord, and DM in your personal list of targets:
target_ids=1003980922525 1511697499654459422 1812605657
# Iterate over your targets
for ((i=0; i<${#target_ids[@]}; i++)); do
target_id=${target_ids[$i]}
if [ $? -ne 0 ]; then
echo "ERROR: Executed command failed ($target_id)"
else
update_message="DynDNS updated in your ${target_id}..."
case $target_id in
telegram) update_message+=" channel-1003980922525-$'\''"
;;
discord) update_message+=" channel-1511697499654459422-$'\'"'
;;
"chat") update_message+=" channel-%'s-(DM)-1812605657" ;;
esac
echo "$update_message\n"
fi
done
