我正在寻求一些有关 SSH 的帮助。
我有一台 Mac，上面安装了 VirtualBox。上面有 2 个 VM，一个是 Windows 10 VM，另一个是 Ubuntu。两个 VM 在仅主机网络上互相暴露。
我在 Windows VM 上使用 PuttyGen 生成了一个 ssh 密钥，复制到剪贴板，在我的 ubuntu vm 上打开 authorized_keys 文件并将其粘贴为-s。此后，我成功地从 Windows ssh 连接到 Linux (Ubuntu)。
现在，我希望我的 Mac 也能有同样的行为，能够通过 SSH 连接到 Ubuntu VM。不幸的是，它不起作用。它显示 permission_denied。我尝试了所有可能的方法，在网上搜索了很多，但无济于事 :( 这是我遵循的步骤 - 请有人帮忙。提前谢谢！
我在 Mac 上生成了 ssh 密钥 - 使用“ssh-keygen -t rsa -b 4096”命令，该命令将密钥存储在我的 id_rsa.pub 文件中。
这是我的 Mac 上的 .ssh 文件夹的样子
drwx------ 5 JK staff 170 Nov 14 21:27 . drwxr-xr-x+ 36 JK staff 1224 Nov 14 20:10 .. -rw------- 1 JK staff 3243 Nov 14 21:27 id_rsa -rw-r--r-- 1 JK staff 756 Nov 14 21:27 id_rsa.pub -rw-r--r-- 1 JK staff 345 Nov 14 16:42 known_hosts现在我将密钥从 id_rsa.pub 复制到了 mu ubuntu 上的 authorized_keys 文件中
Ubuntu /.ssh 目录如下所示
drwx------ 2 vagrant vagrant 4096 Nov 14 21:53 . drwx------ 4 vagrant vagrant 4096 Nov 15 01:40 .. -rw-r--r-- 1 vagrant vagrant 1557 Nov 15 03:47 authorized_keys我甚至尝试执行 chmod 700 authorized_keys，但没有成功
我可以确认 Mac 上的公钥已成功复制到 Ubuntu 上的 authorized_keys
这是 ssh 输出

根据您的帖子，您在 /.ssh/authorized_keys 中安装了您的公钥，并且您正在以用户“vagrant”的身份进行连接，这意味着您必须在 /home/vagrant/.ssh/authorized_keys 中安装您的公钥
