CHAPTER 16: ADVANCED CONFIGURATION
Someone could be eavesdropping on you right now using a 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
ab:7e:33:bd:85:50:5a:43:0b:e0:bd:43:3f:1c:a5:f8.
Please contact your system administrator.
Add correct host key in /.ssh/known_hosts to get rid of this message.
Offending key in /.ssh/known_hosts:1
RSA host key for remhost has changed and you have requested strict checking.
Host key verification failed.
If the host key has legitimately changed, it can be removed from the ~/.ssh/known_hosts file and the new fingerprint added. If it has
not changed legitimately, this indicates a serious problem that should be investigated immediately.
