I am considering attacks, actually i have proof of them and that's why i am posting here, trying to find out how they can get in other than SSH and FTP.

I do regular updates of my server so as far as i know everything is patched, should be no vulnerabilities,also,no one else has access to the server.

To brute-force my root account 506938 times they will need 253469 IP's cause they get permanently banned after 2 failed login attempts, but even if they did, my password is over 30 randomly generated characters long including upper + lower case letters, numbers, symbols and brackets.

For comparison a 10 char password with upper + lower case letters and numbers has a bit over 107 Billion combinations so i wish them good luck if they try to brute-force their way in lol.

Thats why i've posted here though to find out other ways they can get in other than SSH or FTP login so i can take measures to stop them or reduce their chances of success.
