Many times when I try to log-in to a Raspberry Pi via SSH I get the following message:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! 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. The fingerprint for the ECDSA key sent by the remote host is SHA256:8ayjxAjx4Kar+HObByJH0JBPCfWwAGHytmiNKGxUl90. Please contact your system administrator. Add correct host key in /home/peterm/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /home/peterm/.ssh/known_hosts:8 remove with: ssh-keygen -f "/home/peterm/.ssh/known_hosts" -R "192.168.1.9" ECDSA host key for 192.168.1.9 has changed and you have requested strict checking. Host key verification failed. Q1: What is creating this Host key, Is it a combination of the hardware and the Raspbian OS? Q2: How do I change the system so that it is not 'strict checking'? and [Q3] do I want to as this PC is also used for Internet access? All of my Pis use the same IP address for Ethernet connection, and a different fixed IP address for wireless connection. I only ever connect one at a time. Thanks for your help.
