参考#82 心跳认证错误的原因可能是crc校验部分是八字节 #92 似乎是一个成功的例子

## 运行drcom.py得到以下结果 pppoe: received challenge response packet:070110000202000092dd55010a1e84d8a8a80000e659f16700000000dc020000 pppoe: send heartbeat request packet:0702600003000000000000000a1e84d80062006992dd550136d1af410000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 pppoe: heartbeat response failed, retry pppoe: reset idx to 0x01 pppoe: send challenge request packet:0701080001000000 pppoe: received challenge response packet:0701100002030000afdd55010a1e84d8a8a80000e659f16700000000dc020000 pppoe: send heartbeat request

运行drcom.py时因为发送心跳后一直 response failed，所以没有执行 keep_alive_2 的代码

[ly0]

82 的脚本试过了吗

[JerryChaox]

试过了还是不行

[ly0]

@JerryChaox 反馈一下#82 的日志到这个issue里吧

[JerryChaox]

代码里面好像并没有运行到 _gen_crc 那一块呀

[mchome]

正常，因为修改的是keepalive部分23333333

[JerryChaox]

上传一个Linux系统下(ubuntu 16.04LTS, 关闭了防火墙)广东工业大学5.2.1p可用的官方拨号客户端 root下运行privilege, 然后pppoe拨通之后(账户名前面要加\r\n), 运行DrClientLInux就可以拨通. https://pan.baidu.com/s/1bo9Aecv dtgz 贴上一个拨通后的日志,希望有用: dubug_log.txt

[ly0]

发一下一个正常客户端登陆的截包

[mhlau233]

目前只能用交换机+代理共享了

[ly0]

@liuminghao233 如果有时间看一下#82最后回复测试一下

[mhlau233]

@ly0 已发

[JerryChaox]

参考#82最新脚步!!!

[Linjieqiang]

@JerryChaox 同广东工业大学 搞定了吗？

[ouyangyueying]

@JerryChaox 广工同胞，搞掂了？
