Sending ICMP Packets with Python Socket: Adventure in Signaling

In this article, I demonstrate how to craft and send ICMP packets using Python raw sockets, covering packet structure, checksum calculation, and low-level network communication.

Beej (aka Brian Jorgensen) got tired of all his friends asking him how to do stuff with networking-programming in C —

So, in the mid 1990s he put it all online for free.

And, he has been updating it since then.

It covers: TCP, UDP, IPv4, IPv6, blocking & non-blocking I/O, client-server programming, select(), poll(), and more.

Beej's Guide to Network Programming has been an influential book.

Omar Ashour and I are now live-streaming Monday morning around 10:00am-ish MDT. Will we always be live? Not sure, but for now we are having a good time. Come join us if you can.

Our last live-stream we started writing a C program to send a ping. Why? Because Omar Ashour wanted to learn more about low-level networking. Spoiler: we didn't complete the app but we do have a good discussion of hex, binary math, and bit shifting in-between the over two hours of fumble around C.

New World Fabric devlog goes over the interface and rules for the system that automatically networks running C++ code with real examples from Narball. https://www.youtube.com/watch?v=uVlNlhh-mT8

I made a video explaining how my game engine warps time to hide network latency. It includes a bunch of animations showing the tradeoffs of some other common networking approaches as well. https://www.youtube.com/watch?v=g52nosxz4cY

Go workshop - 2º encontro

Laboratório Hacker de Campinas, quarta-feira, 9 de julho às 19:00 BRT

No nosso segundo encontro, vamos constinuar a desconstrução do feed-reader e conhecer um pouco mais dos tipos da linguagem e discutir alguns erros comuns.

Esse sessão será 100% mão na massa.
