我有这个 ssh 配置
Host srv.example.com srv
HostName srv.example.com
User theo
PasswordAuthentication no
ServerAliveInterval 240
ServerAliveCountMax 2
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
我在 mingw 中打开 git 控制台，从我的电脑和遥控器中删除旧的 .ssh/id_rsa 密钥，然后输入
> ssh-keygen -t rsa
...
> ssh-copy-id -t ~/.ssh/id_rsa.pub srv
(password prompt)
> ssh aiadm
[email protected]: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password,keyboard-interactive).
