@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@
@ 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 the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
5c:4d:dd:fd:xxx:93:f0:33:9xxb2:8f:c8xxx.
Please contact your system administrator.
Add correct host key in /Users/Matthew/.ssh/known_hosts to get rid of this message.
Offending key in /Users/Matthew/.ssh/known_hosts:1
RSA host key for xxxxxx has changed and you have requested strict checking.
