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 sys-
tem’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 nonhashed entries. The system will
display the first-time authentication message (page 708) again as
OpenSSH verifies that you are connecting to the correct system.
