I have a Linux 6.2 vps with a cpanel. I think possibly that i have been the subject of a brute force attack that has locked me out. I am trying to access my root server via putty but cannot do this because I am getting this error No support authentication methods available-server sent public key gssapi-keyex gssapi with mic. So I cannot get in via Cpanel or the root server HELP.
If you have any servers logged in for that cPanel server as root or try to login as root(to that cPanel server) from a different machine. Then, this doc can help further!
