无法SSH本地主机

我无法SSH本地主机。我已经在我的Ubuntu 12.04 LTS(32位)上安装了OpenSSH服务器。

连接到网络(IP:192.168.1.2)
安装hadoop,为本地机器运行hadoop。

这是我得到的:

最佳答案

评论中,您的OpenSSH服务器配置文件(/etc/ssh/sshd_config)为空。通过清除并重新安装来重新安装配置文件:

  1. 删除配置文件:

    sudo rm /etc/ssh/sshd_config
    
  2. 吹扫:

    sudo apt-get purge openssh-server
    
  3. 安装:

    sudo apt-get install openssh-server
    
  4. 醇>

    可能不起作用,请遵循:如何恢复配置文件?
