linux搭建SSH服务器
linux，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

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
