Unlock TCP Secrets: Visualizing Handshakes and Retransmissions with Wireshark & tcpdump

This guide walks you through building test environments, capturing packets with tcpdump, visualizing them in Wireshark, and dissecting TCP features such as three‑way handshake, retransmission timers, fast open, flow control, Nagle algorithm and delayed ACKs, while showing the exact Linux kernel parameters that control each behavior.
