SSH登录连接Linux服务器提示The authenticity of host can't be established ECDSA key
fingerprint is SHA256: Are you sure you want to continue connecting
(yes/no/[fingerprint])?
SSH ECDSA key fingerprint is SHA256
解决SSH The authenticity of host can't be established
SSH命令连接云服务器:ssh root@服务器ip地址,提示如下:
The authenticity of host ' ' can't be established.
ECDSA key fingerprint is SHA256:.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
SSH连接服务器为什么会出现这个提示?新手站长网猜测可能是一种安全机制,出现这种情况一般有两个原因,一个是第一次登录云服务器,另一个是主机key发生了变化,解决方法很简单,输入yes,然后回车即可。
那么问题来了,如果经常出现这个SSH提示怎么办?可以在SSH的时候加上StrictHostKeyChecking选项,新手站长网举例说明:ssh -o
StrictHostKeyChecking=no root@你的本地IP地址。
还有一种彻底去掉SSH主机验证的方法,就是修改/etc/ssh/ssh_config配置文件,在ssh_config配置文件中添加:
StrictHostKeyChecking no UserKnownHostsFile /dev/null
新手站长网是不建议这么做的,毕竟不安全。而且一边输入yes回车即可解决问题,没必要这么麻烦。
