OpenSSH是用于使用SSH协议进行远程登录的主要连接工具。它对所有流量进行加密，以消除窃听，连接劫持和其他攻击。此外，OpenSSH还提供了一整套安全的隧道功能，多种身份验证方法和复杂的配置选项。

OpenSSH套件包含以下工具：

远程操作使用 ssh， scp和 sftp完成。

使用ssh-add， ssh-keysign， ssh-keyscan和 ssh-keygen进行密钥管理。

服务端由sshd， sftp-server和 ssh-agent组成。

win10 开启OpenSSH服务

设置-应用-应用和功能-管理可选功能-添加功能
安装OpenSSH服务器和客户端，提示需要重启完成安装，重启电脑

非 win10 安装OpenSSH服务

1. 下载OpenSSH windows版本

下载地址：https://github.com/PowerShell/Win32-OpenSSH/releases

2 解压到C:\Program Files\OpenSSH （官方要求地址）

3 cmd到OpenSSH服务

1）安装sshd服务

powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1

2）开放22端口（如果你在windows关闭了防火墙并配置了入站规则可以不执行如下命令，多执行不影响）

netsh advfirewall firewall add rule name=sshd dir=in action=allow protocol=TCP localport=22

3）配置开机自启sshd服务

sc config sshd start= auto

到此就安装完成

4) 将C:\Program Files\OpenSSH添加到path中，免得每次都要切到C:\Program Files\OpenSSH才能使用ssh，启动ssh服务

net start sshd

新增系统环境变量

启动OpenSSH服务

net start sshd

OpenSSH SSH Server 服务正在启动 .

OpenSSH SSH Server 服务已经启动成功。

OpenSSH服务新增用户

net user root 123456 /add

net user root 123465 /active

OpenSSH验证是否安装成功

安装成功之后，在cmd命令提示符窗口中输入 ssh 即可运行OpenSSH。如下图

3.安装WinRAR--远程解压zip包

1）安装WinRAR解压软件（5.30版本）

2）新增系统环境变量

WinRAR 解压命令

winrar x D:\WebVr\zip\0ebbd570a3cd424fadd6947742e7073f\Train.zip -r D:\WebVr\zip\0ebbd570a3cd424fadd6947742e7073f\

SSH远程winrar不是内部或外部命令，也不是可运行的程序

问题描述：

1.通过ssh远程控制用户

命令：ssh [email protected] 输入密码后

2.通过winrar命令行解压文件

命令：winrar x 文件路径及文件名 -r wenjian 文件路径

示例：winrar x D:\WebVr\zip\71ee2c8ef24248e9b1368cac6831f16b\Train.zip -r D:\WebVr\zip\71ee2c8ef24248e9b1368cac6831f16b\

提示：

解决办法

根本来说， WinRAR 在系统变量的PATH路径信息没有更新

1.通过ssh远程控制用户

命令：ssh [email protected]

2.回显环境变量

命令：echo %PATH%

3.查看系统环境变量以及用户环境变量

4.对比系统环境变量与回显环境变量是否一致，不一致为此问题的原因

5.修改系统环境变量，（winrar建议安装在默认位置）

6.重启openssh服务，重新加载PATH信息

命令：services.msc

7.回显环境变量，最终检查

命令：echo %PATH%

红色框为新增路径，蓝色框为原来错误路径，蓝色框路径存在不影响

8.解压

命令：winrar x 文件路径及文件名 -r wenjian 文件路径

示例：winrar x D:\WebVr\zip\71ee2c8ef24248e9b1368cac6831f16b\Train.zip -r D:\WebVr\zip\71ee2c8ef24248e9b1368cac6831f16b\
