Why HN links it

HN readers link saminiir's five-part "Let's code a TCP/IP stack" series, which builds a TCP/IP stack in code from Ethernet and ARP through TCP data flow and retransmission.

Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

    ARP's fun but it's arguably the least fun bit of the TCP/IP stack.

    In case you didn't realize it at first (I didn't until I happened to click on "/home"), this is the first of a 5-part series: 1. Ethernet & ARP (this post) 2.

    A good way to internalize how everything works is to mess around with pcaps and Wireshark. Try using libpcap (or even just scapy) to decode protocols and see if you can match the Wireshark output, then move up to reconstructing streams and dealing with quirks like fragmentation, etc. If you're looking for something more structured and/or in-depth, try implementing a basic userspace tcp/ip stack. We had a few project…

    Here's one of three parts on coding your own TCP/IP stack. I haven't gotten around to it, but it looks solid. http://www.saminiir.com/lets-code-tcp-ip-stack-1-ethernet-ar...
