How to Diagnose Network Packet Loss: Practical Steps from ping to tcpdump

This guide explains how to systematically investigate network packet loss on Linux by collecting timestamps, routing, interface and kernel statistics, using ping, tracepath, curl, netstat, ss, nstat, ip, ethtool, nftables/iptables, and tcpdump on both ends, then narrowing the failure scope, fixing MTU, conntrack, soft‑interrupt or firewall issues, and validating the fix with metrics and roll‑back procedures.
