SSH Security Warning Dialog Box
The SSH Security Warning dialog box is displayed when a remote host key is not saved in the host key database or the fingerprints of the remote host key and the saved host key are different.
Accept Once
Accept host key for this connection only. The host key is not saved and the same dialog box opens at the next connection. This is useful when a server host key changes often or the user rarely connects to the server.
Accept and Save
Save host key and process the connection. This dialog box does not open on the next connection. This is useful when the fingerprint is correct and the user connects to the host frequently.
Cancel
Host key is not accepted and connection is cancelled.
