vibe coding 了个端口敲门工具，欢迎体验 knock-proxy 是一个端口敲门 TCP 转发工具。服务端用防火墙默认 DROP 公网 TCP 端口；客户端先发送 knock ，服务端验证后临时放行来源 IP ，然后客户端连接同一 TCP 端口，完成 HMAC-SHA256 二次认证并转发到本机 upstream 。 适合隐藏 SSH 、RDP 、数据库管理端口、Web 管理后台等 TCP 服务。 项目地址 <https://github.com/ming79486/knock-proxy> via V2EX 分享创造 标签: #端口#TCP#knock ⚡️探索号频道 ⚡️探索者频道 ⚡️探索者交流群 ⚡️ Youtube 频道：科技探索者 每天推荐有趣内容，欢迎订阅、转发。

[$] More accurate congestion notification for TCP 更准确的 TCP 拥塞通知机制 AccECN 即将在 Linux 内核 7.0 版本中默认启用。这一机制改进了 TCP 协议中显式拥塞通知（ECN）的精度，有望提升公共和私有网络中的流量传输效率。 AccECN 通过更精细地反馈网络拥塞状况，帮助 TCP 连接更及时地调整数据传输速率，从而减少延迟和丢包。该功能已在过去几个内核版本中逐步引入，7.0 版本将默认开启以供广泛使用。 原文链接：https://lwn.net/Articles/1058666/ #网络协议#Linux内核#TCP#ECN #AIGC Read more

http://www.jaggedverge.com/2017/11/how-a-web-page-request-makes-it-down-to-the-metal/ How a web page request makes it down to the metal by : Janis Posted in : Tutorials, work-in-progess Tags : #NGINX, #Python No Comments The other day I was interested in how many steps occur between sending a #POST or #GET#request from a website to the actual processing that happens on the CPU of the #server. I figured that I knew bits and pieces of the puzzle but I wanted to see the complete path from the highest levels of abstraction all the way to the lowest without missing anything too big in-between. It turns out that in a modern web system there are a lot of steps. I have been really fascinated by this much like the explorer that wants to find a path from one known place to another. If you are interested in better understanding how your computer works you might find walking along this path with your tech stack helpful.
