腾讯云服务器重装系统后,SSH报错问题解决

本人因为服务器配置有点乱, 重置了一下系统. 结果发现本地SSH连接不上, 报以下错误 :

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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:HMTDHqBPQZI1+KasA6ZxwA/OL1BI7v0r9fSL6kfRIgk.
Please contact your system administrator.
Add correct host key in /Users/hgw/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/hgw/.ssh/known_hosts:1
ECDSA host key for 124.222.223.222 has changed and you have requested strict checking.
Host key verification failed.

在csdn上看到最多的办法是删除 /Users/hgw/.ssh/known_hosts, 结果仍旧无效 .

解决办法

修改 /Users/hgw/.ssh/known_hosts 配置文件内容, 将远程主机发送的ECDSA密钥修改替换掉原来的

hgw@HGWdeAir ~ % vim /Users/hgw/.ssh/known_hosts
# 内容为
124.222.223.222 ecdsa-sha2-nistp256 SHA256:HMTDHqBPQZI1+KasA6ZxwA/OL1BI7v0r9fSL6kfRIgk.

好啦问题解决啦
