  • 【转】ubuntu下允许root用户ssh远程登录

    原文链接 http://blog.sina.com.cn/s/blog_7e64a87b0100rn8w.html

    SSH服务器,可以通过SSH协议来访问远程服务器,代替telnet和ftp。

    但是ubuntu默认是不启用root用户也不允许root远程登录的。所以需要先启用root用户

    启用root用户:sudo passwd root      //修改密码后就启用了

    安装OpenSSH server:

    1. 使用apt命令安装openssh server

    $ sudo apt-get install openssh-server

     

    2. 可以对 openssh server进行配置

    $ sudo vi /etc/ssh/sshd_config

    找到PermitRootLogin no一行,改为PermitRootLogin yes

     

    3. 重启 openssh server

    $ sudo service ssh restart

     

    4. 客户端如果是ubuntu的话,则已经安装好ssh client,可以用下面的命令连接远程服务器。

    $ ssh xxx.xxx.xxx.xxx

    如果是windows系统的话,可以使用SSH Secure Shell等ssh软件进行远程连接。

    spark@liuhy:~$ sudo vi /etc/ssh/sshd_config 
    
    # Authentication:
    LoginGraceTime 120
    #PermitRootLogin without-password
    PermitRootLogin yes
    StrictModes yes
    
    
    spark@liuhy:~$ sudo service ssh restart 
    ssh stop/waiting
    ssh start/running, process 2977
    spark@liuhy:~$ 
    
    
    spark@liuhy:~$ ssh root@192.168.1.112
