## 2.1. Windows系统

* 安装ssh

   直接安装git工具即可支持ssh

安装完后确认：
```
xiaojiazhu@ubuntu:~/project/rkipc/battery/ipc-rk1106/ipc-sdk/cmake-shell$ ssh
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
           [-b bind_address] [-c cipher_spec] [-D [bind_address:]port]
           [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
           [-i identity_file] [-J [user@]host[:port]] [-L address]
           [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
           [-Q query_option] [-R address] [-S ctl_path] [-W host:port]
           [-w local_tun[:remote_tun]] destination [command]
```

* vscode安装ssh插件

   使用 Remote - SSH 插件

* ssh密钥配置

1. Windows生成密钥；
2. 把xxx.pub文件内容拷贝到虚拟机的ssh目录下的authorized_keys文件；
此处是：

```
xiaojiazhu@ubuntu:~/project/.ssh$ pwd
/home/xiaojiazhu/project/.ssh
xiaojiazhu@ubuntu:~/project/.ssh$ ls
authorized_keys  id_rsa  id_rsa.pub
```

这样设置后，每次登录ssh无需手动输入密码；

3. 在Windows远程登录虚拟机：
   
参考命令：ssh xiaojiazhu@192.168.1.29

```
PS C:\Users\xjz\.ssh> ssh xiaojiazhu@192.168.1.29

## 2.2. vscode设置

配置文件参考

```
Host dgiot // 自定义的主机名
  HostName 192.168.1.29 // 远端的IP地址
  User xiaojiazhu 用户名
  Port 22
  IdentityFile "C:\Users\xjz\.ssh\id_ed25519" // 本端的私钥文件路径
  ForwardAgent yes // 忽略
```

多个远端IP复制即可。
