I tried using ssh-keygen -R but it gave some error. I tried to ssh to my router using the ssh command, then it asks for the password but I couldn't log in as it gives permission denied. However, when I try using sudo, it again gives the old error of WARNING: POSSIBLE DNS SPOOFING DETECTED! and Remote host identification has changed. I saw a number of similar issues but most of them get solved by the above command. What's the way to resolve it? Any help is appreciated.ssh command verbose output strong text
