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:r4COfaGRW6a9yYrF2tQRnKeZbPJj1UKfJyBBfliBJPw.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:2
ECDSA host key for 10.0.0.8 has changed and you have requested strict checking.

查看上面的提示信息，提到了ECDSA 主机**已经改变了，需要重新验证；解决方法如下：
[[email protected] ~]# cat .ssh/known_hosts
10.0.0.100 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBDZ
2U70/h64gLIwwkU/aDMNS3iojTZKjJEWJLhgYMR1UuzAZ0U8+2CET+LOSLNfzKwu/HsZ+RLVY1anKbl8GaoM=
10.0.0.8 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBAJAD
BLVf9YypCk5SyI6SqsVLJ3sgSBR8LY7iC3kExg17RaybzCgxqQhEP7+RuOerMlgSJpBGmE/8dMBhC4cKMc=
删除对应的IP地址，即10.0.0.8的ECDSA：
[[email protected] ~]# cat .ssh/known_hosts
10.0.0.100 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBDZ

重新连接生成ECDSA：
[[email protected] ~]# scp /data/redhat-release.gpg 10.0.0.8:/data/
The authenticity of host '10.0.0.8 (10.0.0.8)' can't be established.
