This script will change ssh listening port from the default 22 to 9000, this is a delibrate choice to help avoid malicious attempts to scan/break into your VPS.
As of 2023, many VPS providers enable firewalla by default & only allow 22 in their default setting. You need to make sure port 9000 is open before running this script on your server, else there's no way to ssh into your server & you have to do full reinstall.
On Ubuntu, the firewall manager is ufw, you can check its status using ufw status. I personally would turn the firewall off by running ufw disable.
You can use namp to check whether a specific port is open on remote machine: nmap -Pn {ip} -n {port}

That being said, running init.sh requires sudo access, do it at your own risk.
