putty 连接到 VM CentOS 7 (Vagrant / Virtualbox) 时出现问题

我已经使用 Vagrant (2.2.3) 和 Virtual Box (5.2.24) 在 Windows 10 上以这种方式创建了一个 VM CentOS7（遵循这些说明...https://blog.centos.org/2019/02/updated-centos-vagrant-images-available-v1901-01/）

vagrant init centos/7
vagrant up

一切正常

然后我安装了 Guest Addition (rif.https://github.com/dotless-de/vagrant-vbguest）， 这样

vagrant plugin install vagrant-vbguest

我的最终结果Vagrantfile如下

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.synced_folder ".", "/vagrant", type: "virtualbox"

  config.vm.provider "virtualbox" do |vb|
     vb.memory = "4096"
     vb.name = "Test"
   end
end

执行vagrant up效果很好

VM 启动，但当我尝试使用 IP 地址 (192.168.33.10) 通过 Putty（端口 22 上的 SSH）连接时，出现以下错误

我哪里做错了？

我已经解决了！

我已编辑/etc/ssh/sshd_config文件并将其sudo vi /etc/ssh/sshd_config更改#PasswordAuthentication yes为PasswordAuthentication yes（取消注释该行...）。

然后我使用命令重新启动了 sshd 服务 sudo systemctl restart sshd ，现在当我从 Putty 连接我的 VM CentOS 7 时一切正常。
