@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

The ECDSA host key for raspberrypi.local has changed,

and the key for the corresponding IP address 192.168.3.12

has a different value. This could either mean that

DNS SPOOFING is happening or the IP address for the host

and its host key have changed at the same time.

Offending key for IP in /home/fseigojp/.ssh/known_hosts:1

  remove with:

  ssh-keygen -f "/home/fseigojp/.ssh/known_hosts" -R "192.168.3.12"

@    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:ZF2oZwd0xaZPE/PL9JnFWnD5tjpGXWYj+xuL0T5KGvQ.

Please contact your system administrator.

Add correct host key in /home/fseigojp/.ssh/known_hosts to get rid of this message.

Offending ECDSA key in /home/fseigojp/.ssh/known_hosts:3

  remove with:

  ssh-keygen -f "/home/fseigojp/.ssh/known_hosts" -R "raspberrypi.local"

ECDSA host key for raspberrypi.local has changed and you have requested strict checking.

Host key verification failed.

というエラーがでるので

ssh-keygen -f "/home/fseigojp/.ssh/known_hosts" -R "raspberrypi.local"を実施
