When you try to connect to a remote system using an OpenSSH client and you see a message warning you that the remote host identification has changed, what has happened? What should you do?
What will be an ideal response?
This message indicates that the fingerprint of the remote system is not the
same as the local system remembers it. Check with the remote system’s
administrator to find out if something changed. If everything is in order,
remove the remote system’s key from the file specified in the error message
and try logging in on the remote system again using ssh. You can use ssh-
keygen with the –R option followed by the name of the remote system to
remove both hashed and non-hashed entries. The system will display the
first-time authentication message (page 773) again as OpenSSH verifies that
you are connecting to the correct system.
