Cron does not work on Openwrt. How to setup?

Question

linux

There is this script:

*/10 * * * * root curl "http://myddns.ru/ddns/?login=мойлогин&pass=мойпароль&domen=domen.myddns.ru"

The script is supposed to update my IP in DDNS records, but after reboot it doesn't work. If you just execute it, the update happens. In /var/log/ did not find logs on Crontab.
I ask you to help
ps - for security purposes, I removed the login-password.

Answer 1

1. Make sure /etc/crontab has a newline character at the end
2. Enable (/etc/init.d/cron enable) and restart the cron daemon (/etc/init.d/cron restart)
3. Try adding /dev/null 2>&1 at the end of the script

Answer 2

By analogy with Ubuntu: Specify the full path to curl
