Occasionally, you may receive an error message upon logging in to a system such as the following:

@@ 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.

This can be a result of normal system maintenance that results in a changed RSA public key, or could be an actual security incident. If the RSA fingerprint displayed by your SSH client does not match the OLCF-authorized RSA fingerprint for the machine you are accessing, do not continue authentication; instead, contact help@olcf.ornl.gov.
