Question

我有一台MacBook，但由于错误，我尝试为GitHub设置pas无字ssh访问权限，并且肯定搞砸了。我是Mac的新手，我不知道如何解决以下问题。

当我尝试建立ssh连接时，得到以下信息

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 RSA key sent by the remote host is
SHA256:DrvZ0osXO8YCnPwEaWyiGKf/SxQGcCZBoNcPrhEdKmI.
Please contact your system administrator.
Add correct host key in /Users/rakeshravi/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/rakeshravi/.ssh/known_hosts:4
RSA host key for rivanna.hpc.virginia.edu has changed and you have requested strict checking.
lost connection

根据我在在线论坛上发现的内容，我正在尝试以下命令，但是无济于事。

ssh-keygen -R hostname

我得到以下答复。

do_known_hosts: hostkeys_foreach failed: No such file or directory

Answer 1

您可以使用自己喜欢的编辑器文件/Users/rakeshravi/.ssh/known_hosts打开并删除第4行并保存该文件。下次您尝试连接到主机时，系统将要求您将新密钥添加到known_hosts

Answer 2

添加选项 -o "StrictHostKeyChecking no"。这将禁止任何检查。示例：

    ssh root@localhost -o "StrictHostKeyChecking no"

ssh远程主机标识已更改，无法修改ssh密钥
