大神，你的固件自己装 OpenClash 始终遇到问题，但是我又喜欢这个最极简的固件。当前版本是 21.02-SNAPSHOT r15894-69b77dc3b4，OpenClash v0.40.7 能启动但是上不了网，v0.40.8 以上版本启动不了。

[nicholas-opensource]

请问您有日志提供吗，自己安装OpenClash是非常不错的选择

感谢您的回复！我去开一个新贴贴日志

I want to ask a question.
I downloaded openwrt source code, and I want to modify the iptables,NAT,filter files , then to compile the source code.
I face a problem which it is that I didn't find the path of these files for example in target or package or any where.

So, if you can tell me how can I find the path of these files, and If you give me some notes.

Thanks.

I want to ask you a question.

Is there in openwrt source code a file responsible for packet capture or sniffer or raw socket?

Firewall can make reject, accept or redirect, but how it can know the packet detailed, on what it depend on which file ?

[nicholas-opensource]

Tcp dump

https://openwrt.org/packages/pkgdata/tcpdump

[omransh]

Is tcp dump already installed and worked in openwrt ? or I should make something to activate its role ?

[nicholas-opensource]

opkg update && opkg install tcpdump

You can use like tcpdump -i any -w files.cap to export cap files and open it in the Wireshark

Brother,
I search about .c file written in c language that responsible for packet capture(like packet socket), and used for nating,filtering ..etc .
So, can you tell me where can I find this file ?

[omransh]

I need to see the code of packet capture(udp,tcp) in networking in the Linux Kernel.
Can you tell the location of file that contain the code?

[nicholas-opensource]

I am not very familiar with the Linux network stack. I'm sorry I can't help you

集成大鹅了吗～哥哥

[nicholas-opensource]

当然，路径/usr/bin/dae，daed也集成了

[Alexrobot03]

哥哥，TP 5480咋样

[nicholas-opensource]

初始版本的配置是很好的，现在有些减配，而且方案现在有些老了。此外系统比较难用，需要一点设置技巧。高通的配置对全安卓方案来说很不错，但是对于使用bcm的Apple设备来说不太理想，没有针对awdl进行优化。

[Alexrobot03]

N100刷完进不去系统，直接进了BIOS，404的没问题，不知道咋回事～

[nicholas-opensource]

当然不是的～

您的头像那嘴唇看起来好sexy，有点骚😆

歪，110吗？

大佬帮忙算个命，遇到一个很奇葩的菜鸡问题，手机是水果，WiFi是5480，不开代理10000.gd.cn手机电信本地测速650Mbps（开dae速度差不多），但是用openclash测速10000.gd.cn手机端速度850Mbps，这是什么原理。

[nicholas-opensource]

建议用ookla speedtest，电信测速我无力吐槽
