Día de cerrar proyectos externos, y organizar mejor los tiempos para avanzar con la creación de contenido gratuito para el blog de #juncotic y el canal de #Youtube... y seguir avanzando con el curso de #hardening #GNU #Linux, que ya queda menos para terminar!

Ah, y sí, empezar a cargar contenido en la nueva plataforma de aprendizaje de JuncoTIC, y optimizar los detalles... pronto novedades!

TCP/IP stack: TheWire13 1.1 for AmigaOS 1.3

Marcel Jähne has published TheWire13, a lightweight TCP/IP stack designed specifically for 68k Amigas running AmigaOS 1.3.
TheWire13 features SANA-II networking, ARP, IPv4, UDP, TCP client connections, a DNS resolver, ICMP ping, a DHCP client, and a bsdsocket.library compatibility layer. So far, the stack has been tested with the a314eth.device and the enc62413.device.

TheWire13 opens new networking options for older Commodore Amiga computers

TheWire13 is one of those releases that sounds simple at first: a lightweight TCP/IP stack for AmigaOS 1.3. That short description is the whole story, and als

Its depressing. #UNIX/#linux is an operating system build around a UART. #TCPIP is designed to make the network look like a #UART. Files are made of UART characters. PIPES are virtual UARTS. Then a ton of optimizations and trickery is added on top to make you forget it’s an UART operating system and make sure it still performs. https://www.linusakesson.net/programming/tty/index.php

🌗 偶發的 `ECONNRESET` 錯誤分析（上）
➤ 當網路通訊遇上「髒」Socket，隱藏的 TCP 重置危機。
✤ https://movq.de/blog/postings/2026-05-05/1/POSTING-en.html
本文探討了在同一機器上運作的兩個服務之間，為何會出現偶發性的 `ECONNRESET` 錯誤。作者透過模擬測試環境，重現了客戶端在讀取資料時收到連線重置的現象。經由 `tcpdump` 與 `strace` 的深入分析，作者發現若伺服器在客戶端尚未讀取完所有資料時便強制關閉 Socket，TCP 協定便會發出 RST 封包，進而導致客戶端出現連線重置錯誤。這種「伺服器端過早關閉連線」的問題在實際生產環境（如 Nginx 與 Gunicorn 的組合）中同樣存在。
+ 這篇分析非常透徹，遇到 `ECONNRESET` 時大家通常會懷疑防火牆，但沒想到是因為應用程式層過早關閉 Socket 導致 TCP 髒資料殘留。
+ 很有啟發性！特別是提到 Nginx 與 Gunicorn 的互動，

I've built a SANA2 TCP/IP stack that works on Amiga OS 1.3!
https://mytube.madzel.de/w/5bm2KTwwBTVvhUT4HHWCcG

amitcp13 (working name) is a standalone TCP/IP stack and minimal bsdsocket.library implementation for AmigaOS 1.3.

The stack runs as a separate process. The current bsdsocket.library is a client-side shim that forwards socket calls to the running stack service through an Exec MsgPort.
