title: Remote host Identification has changed
body: <p>I try to copy a file to my remote server with scp.</p>
  
  <pre><code>sudo scp atlassian-jira-6.4-x64.bin username@ip-adress:/
  </code></pre>
  
  <p>When I execute, I get the error:</p>
  
  <pre><code>WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
      IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
  Someone could be eavesdropping on you right now (man-in-the-middle attack)!
  It is also possible that a host key has just been changed.
  The fingerprint for the RSA key sent by the remote host is
  (fingerprint)
  Please contact your system administrator.
  Add correct host key in /var/root/.ssh/known_hosts to get rid of this message.
  Offending RSA key in /var/root/.ssh/known_hosts:1
  RSA host key for IPADRESS has changed and you have requested strict checking.
  Host key verification failed.
  </code></pre>
  
  <p>So I removed the known_hosts file from ~/.ssh and tried the command again. But still there is this message coming up. Where do I need to modify my files then besides the .ssh folder? </p>
