-### Is my connection compromised? Remote host identification has changed
-
-On Monday 25 April 2022, the login nodes received an update to RHEL8.

-@    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 a host key has just been changed.
-The fingerprint for the RSA key sent by the remote host is
-xx:xx:xx.
-Please contact your system administrator.
-Add correct host key in /home/hostname/.ssh/known_hosts to get rid of this message.
-Offending RSA key in /var/lib/sss/pubconf/known_hosts:1
-RSA host key for user has changed and you have requested strict checking.
-Host key verification failed.

-Please follow the instructions at [migration to RHEL8]({{ hpc_infrastructure_url }}/migration_to_rhel8)

-You will also find how to hide the warning.
