The password entered by ssh user @ localhost on the mac terminal cannot be properly logged in. After returning today, the system suddenly becomes very strange, in the past, ssh user @ localhost was used in the mac terminal to enter a password to connect to the remote SSH server. The following error is always prompted during connection today: kenforlin :~ Kenforstar $ sudo ssh root@192.168.1.203Password: @ WARNING: remote host identification has changed! @ It is possible that someone is doing something nasty! Someone cocould be eavesdropping on you right now (man-in-the-middle attack )!
