The warning message tells you the line number of the entry in the
known_hosts file:

  Add correct host key in /home/rmy/.ssh/known_hosts to get rid of this message.
  Offending key in /home/rmy/.ssh/known_hosts:22
  RSA host key for localhost has changed and you have requested strict checking.
  Host key verification failed.
