使用scp传输文件 Host key verification failed.解决

在用scp传输文件时,看到如下报错信息:

ysgz@ysgz:~/Desktop$ scp check.sh ysgz@192.168.3.6:/tools
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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:KcPDWuynzibxrbck/KdtmHw0/HBdw8oG5ujdex5mync.
Please contact your system administrator.
Add correct host key in /home/ysgz/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/ysgz/.ssh/known_hosts:1remove with:ssh-keygen -f "/home/ysgz/.ssh/known_hosts" -R "192.168.3.6"
ECDSA host key for 192.168.3.6 has changed and you have requested strict checking.
Host key verification failed.
lost connection

这不是什么大问题，只需要按照提示信息,删除~/.ssh/known_hosts即可，

rm -rf ~/.ssh/known_hosts

删了再次scp的时候可以自己生成

ysgz@ysgz:~$ cat ~/.ssh/known_hosts

我出现这个的原因，是不小心把“@”错敲成了“:”
