A really very simple IP update script using duckdns.org dns service.
Edit update_ip.sh script.
Set your duckdns token in $duckDnsToken variable and your subdomain name in the $domain variable
You can also modify the refresh interval in $updateIntervalMinutes variable.
update_ip.sh --install
It will add a new entry to the current user's cron to run the script each $updateIntervalMinutes.
In case something went wrong during the update process, it will write a message log in '/var/sys/log'.
Just enjoy!
