在 #331 里也提到了这个报错，按照他的环境，我无法重现。 你可以自己先多测试测试，尝试给出其他更多环境不同的信息吗？ 发一下 In #331, this error was also mentioned. According to their environment, I am unable to reproduce it. Can you please do more testing yourself and try to provide additional information about different environments? upload result please ，shell : bin/ecapture tls -i eth0 -w a.pcapng

歪个楼，请问你的blueline是怎么用上5.10的内核的，可以展开一下吗 😃 |
|
17万刀片服务器自带的 |
|
了解了，那应该是 redroid 或者 cuttlefish 之类的技术吧? |
应该是你的内核不支持network emulation。 内核编译需要启用相关配置，你可以参考如下链接。 It should be that your kernel does not support network emulation. Enabling relevant configurations is required during kernel compilation, and you can refer to the following link. https://itecnote.com/tecnote/linux-rtnetlink-answers-no-such-file-or-directory-error/ |

重新编译内容后，发现抓到的pcap中没什么请求内容 |
|
抓包文件 |
|
你使用的启动命令、测试shell分别是什么？ 我觉得大概是你监听的网卡不对，不是流量经过的网卡 What are the startup commands and test shells you are using? I think it's probably because you're monitoring the wrong network interface, not the one that the traffic is passing through. |
|
我想把抓包的数据写到数据库，将记录保存下来 |
|
应该是eth0 130|blueline:/data/local/tmp # ifconfig eth0 Link encap:Ethernet HWaddr 48:ad:08:45:1c:01 |
|
使用命令 tc qdisc add dev eth0 clsact |
嗯？ 这条命令有什么问题吗？ 你这个问题的错误原因，在 #347 (comment) 描述的很详细了。 |
|
执行命令不反馈空记录了，到记录无法写入pcap |

完整的命令行发出来，别总发不全的信息。沟通成本很高 |

这里抱错了，我第一次遇到，租需要debug一下。 你的运行环境可以给一下吗？ 详细信息。 |
|
可以的，给个邮箱我发你 |
|
版本信息贴在这呗，不用发邮箱 |
|
OS: [安卓12] 这是环境信息，我的意思你要不远程设备看下 |
|
嗯，这硬件配置，我确实准备不来。 你在我微信公众号里留言吧，我到时加你。 |

感谢大神的支持 |
