Question

我以前使用带有登录凭据的珊瑚板，但SSH似乎无法正常工作，因此我从珊瑚上移走了密钥，以便生成新的密钥，现在它不允许我进入板中了。我对此不满意，请回答。这是我的大学项目。如何更改目录中的快捷键？

Waiting for a device...
Connecting to green-horse at 192.168.101.2
Key not present on green-horse -- pushing

Couldn't connect to keymaster on green-horse: [Errno 111] Connection refused.

Did you previously connect from a different machine? If so,
mdt-keymaster will not be running as it only accepts a single key.

You will need to either:
   1) Remove the key from /home/mendel/.ssh/authorized_keys on the
      device via the serial console

- or -

   2) Copy the mdt private key from your home directory on this host
      in ~/.config/mdt/keys/mdt.key to the first machine and use
      'mdt pushkey mdt.key' to add that key to the device's
      authorized_keys file.

Failed to push via keymaster -- will attempt password login as a fallback.
Can't login using default credentials: Bad authentication type; allowed types: ['publickey']

ssh也应该起作用（这是我所使用的），但是您需要在主机上生成一个密钥，然后将其放入开发板上的~/.ssh/authorized_keys中，其中可能有多个密钥文件，而mdt必须是其中之一。

要恢复mdt访问，可以在此处检查：https://coral.ai/docs/dev-board/mdt/#recover-mdt-access
要使用ssh进入板，请生成您自己的ssh密钥：

ssh-keygen

您的新密钥将位于~/.ssh/id_rsa.pub中，您可以将该密钥放在板上以进行ssh。

有什么办法可以用我的珊瑚开发板解决此问题？
