I had removed both.
Besides the ~/.ssh/known_hosts, I think there is one entry in the the server’s global configuration file. /etc/ssh_known_host , which I don't have access to.
And the one variable $securehostcheck was set to "yes" instead to "ask" ,(I don't remember the name, some thing like $securehostcheck )
