• linux搭建SSH服务器


    搭建ssh服务器

    1.安装ssh服务器:sudo apt-get install openssh-server

     2.查看ssh配置文件:vim /etc/ssh/sshd_config

    # Package generated configuration file
    # See the sshd_config(5) manpage for details
    
    # What ports, IPs and protocols we listen for
    Port 22
    # Use these options to restrict which interfaces/protocols sshd will bind to
    #ListenAddress ::
    #ListenAddress 0.0.0.0
    Protocol 2
    # HostKeys for protocol version 2
    HostKey /etc/ssh/ssh_host_rsa_key
    HostKey /etc/ssh/ssh_host_dsa_key
    HostKey /etc/ssh/ssh_host_ecdsa_key
    HostKey /etc/ssh/ssh_host_ed25519_key
    #Privilege Separation is turned on for security
    UsePrivilegeSeparation yes
    
    # Lifetime and size of ephemeral version 1 server key
    KeyRegenerationInterval 3600
    ServerKeyBits 1024
    
    # Logging
    SyslogFacility AUTH
    88 lines yanked         

    # Authentication:
    LoginGraceTime 120
    PermitRootLogin prohibit-password
    StrictModes yes

    RSAAuthentication yes
    PubkeyAuthentication yes
    #AuthorizedKeysFile %h/.ssh/authorized_keys

    # Don't read the user's ~/.rhosts and ~/.shosts files
    IgnoreRhosts yes
    # For this to work you will also need host keys in /etc/ssh_known_hosts
    RhostsRSAAuthentication no
    # similar for protocol version 2
    HostbasedAuthentication no
    # Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
    #IgnoreUserKnownHosts yes

    # To enable empty passwords, change to yes (NOT RECOMMENDED)
    PermitEmptyPasswords no

                                          1,1           Top
    

     说明:

      Port 22  //默认使用22端口,也可以自行修改为其他端口,但登录时要打上端口号
      #ListenAddress   //指定提供ssh服务的IP,这里我注释掉。
      PermitRootLogin   //禁止以root远程登录
      PasswordAuthentication  yes  //启用口令验证方式
      PermitEmptyPassword   //禁止使用空密码登录
      LoginGraceTime  1m   //重复验证时间为1分钟
      MaxAuthTimes   3    //最大重试验证次数
      保存修改好的配置,退出。

    3.我们先不修改,先择启动服务器

    4.使用SSH客户端登录

    (1)Linux客户机
      # ssh 192.168.1.100   //输入服务器IP登录,不加用户名默认以root身份登录
      或者
      # ssh hui@192.168.1.100   //以hui身份登入服务器


    (2).windows下使用远程登录客户端登录
      时下最流行的是putty这款登录软件,无需安装,下载下来就可以使用,简单、方便、安全!
      ·当服务器使用口令验证方式时,只需输入用户名和密码即可
