ssh登錄 The authenticity of host 192.168.0.xxx can't be established. 的問題

scp免密碼登錄：Linux基礎 - scp免密碼登陸進行遠程文件同步

執行scp一直是OK的，某天在本地生成了公鑰私鑰后，scp到某個IP報以下錯誤

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

參考：好記心不如爛筆頭，ssh登錄　The authenticity of host 192.168.0.xxx can't be established.　的問題,即可不修改/etc/ssh/ssh_config文件的配置而解決此問題

ssh  -o StrictHostKeyChecking=no  192.168.0.xxx　

輸入密碼

 

再次scp，正常輸入密碼，問題解決。

ssh連接The authenticity of host can't be established

修改/etc/ssh/ssh_config文件的配置，以后則不會再出現此問題

最后面添加：

StrictHostKeyChecking no

UserKnownHostsFile /dev/null
