报错案例：root@localhost:~# Connection to 192.168.1.16 closed by remote host.
Connection to 192.168.1.16 closed.

正常情况下/etc/proftpd/proftpd.conf文件配置DefaultRoot /storage/sdcard/ kyon

<Directory /storage/sdcard/>
    AllowOverwrite on
    <Limit ALL>
        AllowALL
    </Limit>
</Directory>

即可正常访问但是有时候不知道为什么，设置之后再起洞proftpd然后使用windows电脑连接就会显示无法访问可能没有权限而且断开ftp会话，同时ssh也莫名其妙断开了，再连ssh都连不上了只能重启再开

解决办法就是：如上把注释掉#DefaultRoot /storage/sdcard/ kyon或者直接删除，然后在默认文件下创建目标文件夹软连接到默认文件夹下，因为没有DefaultRoot设置时登录就会进入用户文件夹，所以我们通过设置软连接欺骗ftp这个文件夹是用户文件夹下的，同时以防万一把前一步的Direct什么什么的protfpd自带权限配置也带上只需要一句ln -s /storage/sdcard/ /home/kyon/sdcard访问就是直接登录用户后加上目标文件夹即可访问，因为这个软连接windows不知道的但是路径里写上Linux就会反馈文件夹给windows变能用
