To solve this problem, you need to use a scheduled cron job in Telegram with specific settings to handle errors and updates for the
dyndns skill.
Here's a detailed solution including bash script as provided:
**Step 1: Create a bash script**
Create a new file, e.g.,
.hermes/cf-dyndns.sh, and paste the following code into it:
``
bash
#!/bin/bash
# Send NO_REPLY if no change occurs
if echo "$2" | grep -q -i "ERROR"; then
echo "NO_REPLY"
else
# Send an update message to all three targets if one line shows a success update
while IFS= read -r line; do
target=${line%%:*}
message="DynDNS Updated: $$ ( ${line#*:} )"
case $target in
"telegram:-1003980922525" *)
telegram_message=\"$message\"
;;
"discord:1511697499654459422" *)
discord_message=\"$message\ ;;
"telegram:1812605657") })
telegram_message=\"$message\
;;
esac
echo "$telegram_message"
done <<< "$1"
fi
`
**Step 2: Set up cron job for cf-dyndns.sh
**
Open the crontab editor and add the following line at the end of each day:
`
0 23 * * * /root/.hermes/cf-dyndns.sh "https://cdn-api DynaDNS.co.uk/v1/yourDynName.php?token=yourToken&maxAge=1728000"
`
If your DynDNS API has the required endpoint, this should update any existing records with an ok
status within 2 weeks. Otherwise, it will show a "NOCHANGE" message to all three channels.
Here's how to set it for Telegram and Discord:
* Use https://cdn-api DynaDNS.co.uk/v1/yourDynName.php?token=yourToken&maxAge=1728000
as the second argument in the cron job.
* Ensure that your DynDNS API has the required endpoint, and if not, update it accordingly for a successful DynDNS update.
Please note that you should replace yourDynName.php
, yourToken
, and yourDyn`: with your actual DynDNS settings.
