通过Paramiko的SFTPClient进行的无密码连接不起作用

Question

我有两个lxd容器，一个master，另一个是slave。我已经将master的ssh-key粘贴到slave的{}，这样我就可以通过简单地从master到{}进行无密码登录

ssh <slave-user>@<slave-ip>

没有任何密码。在

现在，我想用paramiko的SFTPClient将一些文件从master发送到slave。代码应该是：

^{pr2}$

我在我的master节点上运行这段代码，10.154.151.252是{}的IP地址。请注意，我可以使用ssh轻松地将这两个连接起来。在

当我尝试使用无密码登录时，问题就来了。我也试过了 transport.connect(username="root",password="")，但那也没用。在

那么，我是不是遗漏了一些显而易见的东西？在

这是我生成的paramiko日志
