The RSA host key for foo-bar.net has changed,
and the key for the corresponding IP address 127.0.0.1
is unchanged. This could either mean that
DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.
Offending key for IP in /home/user/.ssh/known_hosts:6

From man ssh-keygen (SSH-KEYGEN(1)) -R hostname Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above). Try this:

ssh-keygen -R hostname [-f known_hosts_file]
