ssh登录　The authenticity of host 192.168.0.xxx can't be established.　的问题

Posted 2020-08-26 黄洪波写点东西的地方

scp免密码登录：Linux基础 - scp免密码登陆进行远程文件同步

执行scp一直是OK的，某天在本地生成了公钥私钥后，scp到某个IP报以下错误

The authenticity of host \'192.168.233.137 (192.168.233.137)\' can\'t be established.
ECDSA key fingerprint is SHA256:EsqTfeCJ34DnGV66REuRRPhoFwaLuee5wxFgEAZ8b9k.
Are you sure you want to continue connecting (yes/no)? 
Host key verification failed.
lost connection

参考：好记心不如烂笔头，ssh登录　The authenticity of host 192.168.0.xxx can\'t be established.　的问题,即可不修改/etc/ssh/ssh_config文件的配置而解决此问题

ssh  -o StrictHostKeyChecking=no  192.168.0.xxx　

输入密码

 

再次scp，正常输入密码，问题解决。

ssh连接The authenticity of host can\'t be established

修改/etc/ssh/ssh_config文件的配置，以后则不会再出现此问题

最后面添加：

StrictHostKeyChecking no

UserKnownHostsFile /dev/null
