Description AMBER KELPEN 2017-08-03 15:46:07 UTC
When attempting to log in to x11 I receive this message and am unable to go any further.

bash-3.2$ ssh Amberk@17.104.244.1

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
SHA256:bcsa1TLRCS7tlNnHjrRsOFpQB6lCmZP58Gsl8Zf7o2o.
Please contact your system administrator.
Add correct host key in /Users/amberkelpen/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/amberkelpen/.ssh/known_hosts:1
RSA host key for 17.104.244.1 has changed and you have requested strict checking.
Host key verification failed.
bash-3.2$ 


This is a floor wide issue for our department and is causing widespread issues across the floor as we are no longer able to update our queues and gather reporting.

That message has absolutely nothing to do with X11.  As the message says, the ssh host key from that server does not match what it was in the past, and as a security measure, you are not being connected to the machine.
