@nebulon @girish @d19dotca Thank's a lot @d19dotca ! For me is a little bit complex append that command in cronjob and I don't know if Cloudron make some integrity test at boot time to try to check if turn is on or off.
Another solution is to use VPS provided firewall to lock that doors... But as @nebulon wrote, one improvement could be add rate-limiting and/or start that services on demand.
Thank's all for your answer 🙂
