For this purpose we work on crontab: $ sudo nano /etc/crontabĪt the bottom, the following entry is simply added and the change is saved on the crontab: # NO-IP update To execute the bash script at regular intervals, a cronjob must be created. LOGTEXT="(error) Could not understand the response from No-IP. Retry the update in no sooner than 30 minutes." How to properly install No-IP Dynamic Update Client (DUC) under Raspbian SiZiOUS.
