我在 Windows 7 主机上运行 Oracle Linux VM,并尝试通过 ssh 连接到我的 MacBook。
我已经在我的 Mac 中创建了私钥/公钥。我已将内容复制到文件夹中的文件id_rsa.pub
中。我已将当前用户的权限更改为。和 的权限已更改为。authorized_keys
.ssh
authorized_keys
600
~
~/.ssh
700
我还使用以下命令将 Oracle Linux VM 中的内容复制id_rsa.pub
到authorized_keys 文件中
ssh-copy-id
在我的 Mac 中,我还有一个 Oracle Linux VM,我可以从 Windows 计算机中的 Oracle Linux VM 完美地通过 ssh 连接到该 VM。
但是,我无法仅使用以下命令 ssh 进入我的 Mac:ssh macdomain
我必须使用:ssh username@macdomain
才能成功 ssh。如果没有用户名,它会要求我输入密码,最终结果是:
Permission denied (publickey, keyboard-interactive)
这是我的 sshd_config 文件:

我用谷歌搜索并查看了几乎所有相关主题,但无济于事。
答案1
您在 VM 中的用户名与 Mac 上的用户名不同。默认情况下,ssh
如果您未明确指定,则假定用户名相同。它试图登录不存在(或者您尚未设置)的用户,这就是它总是失败的原因。
为了避免这种情况,您可以每次指定用户名,或者设置您的.ssh/config
文件在虚拟机中像这样:
Host mac
Hostname macdomain
User yourmacusername
这将仅覆盖该主机的默认用户名。如果您愿意,也可以ssh mac
不使用主机名。
