Mongoose
Embedded TCP/IP network stack with embedded web server, Websocket, and MQTT client (by cesanta)
Project mention: Sans-IO: The secret to effective Rust for network services | news.ycombinator.com | 2024-07-03A long time ago I had "fun" implementing all sorts of network protocols with such an event based library on C: https://github.com/cesanta/mongoose

kyanos
Kyanos is a networking analysis tool using eBPF. It can visualize the time packets spend in the kernel, capture requests/responses, makes troubleshooting more efficient.
-
boopkit
Linux eBPF backdoor over TCP. Spawn reverse shells, RCE, on prior privileged access. Less Honkin, More Tonkin.
-
M3 at work, Acer Swift 3 at home. Both are comparable in that regard. You can do 200k QPS of actual work (a little protobuf parsing, a little old-school ML, handling the networking, a little HTTP1.1 parsing, ...), more if you just want vanity metrics, just by wrapping something like uSockets [0] and not doing anything to explicitly pessimize the system.
You can do better with a hand-crafted solution, but most projects don't need anything fancier.

ucall
Web Serving and Remote Procedure Calls at 50x lower latency and 70x higher bandwidth than FastAPI, implementing JSON-RPC & REST over io_uring ☎️
-
DDOS-RootSec
Explore RootSec's DDOS Archive, featuring top-tier scanners, powerful botnets (Mirai & QBot) and other variants, high-impact exploits, advanced methods, and efficient sniffers. Ideal for cybersecurity professionals and researchers.
-
Modbus-STM32-HAL-FreeRTOS
Modbus TCP and RTU, Master and Slave for STM32 using Cube HAL and FreeRTOS
-
-
As far as I know, there are two transparent proxy softwares that can make SOCKS5 proxy available as transparent proxy supporting TCP and UDP: redsocks (forked from old redsocks, which doesn't support TCP transparent proxy) and hev-socks5-tproxy. This is an example config file for hev-socks5-tproxy to host TCP transparent proxy on port 22222 and UDP transparent proxy on port 22224. Debug output is enabled.

-
AMP-Research
Research on UDP/TCP amplification vectors, payloads and mitigations against their use in DDoS Attacks
-
ngx_healthcheck_module
nginx module for upstream servers health check. support stream and http upstream. 该模块可以为Nginx提供主动式后端服务器健康检查的功能（同时支持四层和七层后端服务器的健康检测）
-
netxduo
Eclipse ThreadX - NetXDuo is an advanced, industrial-grade TCP/IP network stack designed specifically for deeply embedded real-time and IoT applications
For those looking for options like LwIP, consider NetXDuo [1] and its counterparts ThreadX, FileX, LevelX, and UsbX (I use TinyUSB instead).
It has been one of the top commercial RTOS network stacks for, I think, 20 years. It moved hands a couple of times and now is supported by the Eclipse Foundation and is MIT-licensed. I'd use it over LwIP.
