If one is found, it checks if the host key send by the remote host matches the Known host key. We recommend however that you select an Host Verification Strategy to prevent man-in-the-middle attack. They are different verification strategies: With this configuration, an authorised Jenkins user with Computer.

CONFIGURE need to manually approve/disapprove the remote host key in Jenkins if it has changed.

Poke results: The known_hosts file does not exist, so the initial load raises an exception, and the SSHClient has an empty Known Hosts object.

When the key is added by the Auto Add Policy, it initially triggers a save call for the file, which attempts to reload the known_hosts file contents, just in case it was externally changed since it was loaded (https://github.com/paramiko/paramiko/blob/master/paramiko/client.py#L137).

Since the file didn't exist at original load time (and still doesn't exist), an exception is raised here as well, bypassing the save code that would normally rewrite/create the file.

The second time the connect() call is made, the host entry is in the Host Entry object (just not saved to disk) so it is found, and not re-added, which would trigger a call to save_host_keys().

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.
