Please notice that the root password can't be restored on our VPS and dedicated server. In case you loose your root password we can only do a backup of your VPS (and send you the file for local mount) or mount your hdd on an extra server.
If you have your server encrypted most likely all your data is lost.
For this kind of reason, we recommend:
Do not set your root password to a 60-letter long password that is hard to type within 10 seconds (timeout time on a Linux shell) - 20 letters are secure to and a simple fail2ban or CSF firewall will stop attacks
Much better of course is to set a key auth, that way brute force is impossible.
We also do not recommend changing the SSH port unless you are sure what you are doing, it will not bring you any extra security, and the port can be revealed by a portscan within seconds. In case of a DDoS attack, the non-standard port is also may blocked by the DDoS protection.
If you want to gain security setup key auth on your SSH (see also https://help.ubuntu.com/community/SSH/OpenSSH/Keys )
