Cron not working?

Dear forum peers,

I have installed Dietpi and I absolutely love it. So much faster, lightweight etc etc.

I have installed pi-hole, PiVPN and unbound and everything works well. However, I have DDNS and cron does not seem to work.
I am new to the idea of Dietpi having its own folders so I may be doing something wrong here. I have installed my script in both cron minutely(every 5 minutes) and cron hourly (default on the 17th minute of each hour). If I run the script, it immediately updates the IP so i know it works. However, cron does not run it as dietpi wants it to. There seems to be no crontab for me to change. What am I doing wrong? Is there a switch to turn on cron?

root@RPi:/etc/cron.hourly# cat

#Run OVH update
/usr/local/bin/ > /dev/null 2>&1

root@RPi:/etc/cron.hourly# cd /etc/cron.minutely/

root@RPi:/etc/cron.minutely# ls  readme.txt

root@RPi:/etc/cron.minutely# ls -lrt
total 8

Judging from here, all I needed to do is just remove the ending from to just ovh

yes correct, you would need to remove the .sh from your script.

As an alternative you could have a look to dietpi-ddns. If you have an update link, you would use the custom entry.
