环境准备

python2.7（调试用到）
wireshark（抓包工具）
notepad++（修改代码用到）
一款支持刷入第三方系统(openwrt)的路由器
该路由器已联网并获得开发者(root)权限
一根网线
下载软件WinSCP
下载软件putty，32位操作系统请下载putty32，64位系统请下载putty64

一、刷入固件

先刷入不死鸟控制台，再通过不死鸟控制台刷入固件，避免因操作失误造成路由器变砖

获取路由器root权限

以极路由1S HC5661A为例，在您购买满14天后，请先登录极路由器后台，然后依次开通、安装开发者插件

开通开发者模式：“云插件”>“路由器信息”>“高级设置”>“开通”
安装开发者插件：“云插件”>“全部插件”>“开发者模式”>”确定”

其他路由器可查看其他教程获取root权限。

刷入不死Breed

下载Breed

Breed是一个路由器的Bootloader（Bootloader 意为引导加载器，即为用于加载操作系统的程序。它是一大类此类功能程序的统称。现在的 BIOS、UEFI、GRUB、RedBoot、U-Boot、CFE等都是 Bootloader），装它的目的是为了下一步刷入固件（ROM）。以极路由1S HC5661A为例，不同型号下载不同的Breed，请务必对号入座，下载breed-mt7628-hiwifi-hc5661a.bin

上传到指定目录

使用WinSCP登入你的路由器后台，其中：

主机名：你的后台管理地址(比如192.168.1或者192.168.1.199)

账号：root

密码：你的后台管理密码

端口：1022或者22(自行测试)

模式：SCP

登陆成功后进入/tmp目录，将刚才下载的breed-mt7628-hiwifi-hc5661a.bin上传到这个目录

刷入Breed

使用putty64登入你的路由器后台，主机名、账号、密码、端口均与上述相同，登入成功后键入以下命令

mtd -r write /tmp/breed-mt7628-hiwifi-hc5661a.bin u-boot

显示rebooting后等待路由重启完成，不死uboot就完成了刷入了。（注意，为了确定百分百刷入成功，建议此时什么都不要动，等待5分钟后再进行其他操作）

请严格按照先后顺序操作

用网线让路由器的LAN口与电脑的网口相连接；
PC设置为自动获取IP(一般默认自动获取IP)；
路由器断电(就是拔插头)；
首先按住reset不放！，确保没有松开reset键后，然后，插入路由器电源；
保持按住reset 3-4秒左右，路由器灯开始一闪一闪的时候，松开reset；
PC网卡获取到192.168.1.x的地址（如未获取到手工设置），一般是192.168.1.1 ；
浏览器访问 192.168.1.1，接着你就会看到一个uboot控制台的界面。

为了保险起见，首先进行固件备份，以备不时之需。严重强烈建议极路由用户刷Breed后，第一次进入后台就备份一次，这样以后想要重新刷回官方系统时原有功能不会受到影响，仍然能够访问云平台。

现在正是开始刷入OpenWrt固件，依次点击固件更新→勾选固件→点击选择文件，选择我们刚刚下载的openwrt-18.06.2-ramips-mt76x8-hc5661a-squashfs-sysupgrade.bin，然后耐心等待固件刷入完成。

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-4a9SJQNp-1638352440059)(https://raw.githubusercontent.com/Editblog/PicGo/main/img/20211201175342.png)]

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-kWceV26l-1638352440060)(https://raw.githubusercontent.com/Editblog/PicGo/main/img/20211201175350.png)]

安装完成后会自动重启，这时可以不断刷新浏览器，直到管理界面显示出来，如果没有显示，建议稍后使用192.168.1.1访问管理页面。

账号:root

密码:默认为admin

二、确定所使用客户端版本

打开学校的客户端，右上角可以看见ver5.2.0（D）

三、网络抓包

1、先断开网络，注销并关闭drcom客户端。

2、打开wireshark，选中你联网用的那个连接。双击开始抓包！如图所示：

软件会进入如下界面

现在打开drcom客户端，拨号连接并在线保持1分钟左右，然后注销，完全关闭drcom后，选择wireshark的停止抓包

选择File-save 选择保存路径，并重命名该文件为dr.pcapng (拓展名为.pcang)

完成抓包

四、解析数据

1.此处提供 drcom_p_config.py 与 latest-wired.py的代码

2.drcom_d_config.py 和 latest-wired.py 和 dr.pcapng 放入同一个文件夹中

3.在文件夹下运行命令python drcom_d_config.py > config.txt生成config.txt文件

4.用Notepad++打开config.txt（为避免不必要的麻烦，以下操作所有的文件全部用它）得到的内容是类似这样的：

server = "192.168.100.150"
username = ""
password = ""
host_name = "LIYUANYUAN"
host_os = "8089D"
host_ip = "10.30.22.17"
PRIMARY_DNS = "114.114.114.114"
dhcp_server = "0.0.0.0"
mac = 0xb888e3051680
CONTROLCHECKSTATUS = '\x20'
ADAPTERNUM = '\x01'
KEEP_ALIVE_VERSION = '\xdc\x02'

5.全选复制config.txt的所有内容，关闭，并把config.txt重命名为drcom.conf（不要忘记填写账号和密码）

6.测试是否可以使用，运行命令行python latest-wired.py ，看看能不能上网。可以的话，就说明抓包没错。

五、路由器配置

1.进入路由器管理后台，搜索dogcom，将两个插件安装

2.在网络里面会出现dogcom选项，将步骤四中解析到的drcom.conf的内容拷贝到配置文件里面，点击保存应用，此时手机与电脑连接WiFi就不需要进行登陆认证
