OpenSSH会在iOS上安装SSH服务，以给外界提供一个通过ssh接入iOS的途径。

这里用的最多的一般只有2个命令：ssh和scp，前者用于远程登录，后者用于远程拷贝文件。

ssh用法：ssh user@iOSIP

示例：Mac远程连接iphone

wifi:~ clf$ ssh root@192.168.2.2
The authenticity of host '192.168.2.2 (192.168.2.2)' can't be established.
ECDSA key fingerprint is SHA256:o2jgbSUKqlEYdg+5xzJsOvY63ZnxhcOCeRxZo9Ibw/Y.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.2.2' (ECDSA) to the list of known hosts.
root@192.168.2.2's password: 
iPhone:~ root# 

scp用法：

1）把文件从本地拷贝到iOS上

scp localFilePath user@iOSIP:romoteFilePath

2)把文件从iOS拷贝到本地

scp user@iOSIP:romoteFilePath localFilePath
