用SSH传输文件时出现下面的信息
[root@xx]# scp -r CentOS7.2-Mini-Newton.tar.gz newton_install-V1.0.4 / 192.168.122.100:/root/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 SHA256:9XvufSSIeZ7MAurIZ1Qw9Z13YV1Zcim2kthmAlECgYw. Please contact your system administrator.

文件传输不过去，只需要删除.ssh目录下的known_hosts文件就能传输了
[root@xx]# rm -rf ~/.ssh/known_hosts
