Linux networking debugging is a specific muscle — and these 5 tools are 90% of it. This lesson teaches the modern toolkit: ip (replaces ifconfig + route), ss (replaces netstat), curl (your HTTP swiss army knife), dig (DNS), and ping (still useful). 🎯 In this lesson: ✓ ip a — show interfaces (the new ifconfig) ✓ ip route — show routing table ✓ ss -tlnp — listening ports + processes (new netstat) ✓ curl -v + -I — HTTP debugging ✓ dig — DNS lookups (A, MX, NS, SOA) ✓ ping + traceroute (still useful, with caveats) ✓ nmcli + nmtui — NetworkManager from the shell ✓ /etc/hosts, /etc/resolv.conf — the config files ⏱ Chapters: 00:00 — Why these 5 tools 01:00 — ip a + ip route 01:30 — ss for open ports 02:00 — curl deep tour 02:30 — dig for DNS 03:00 — ping + traceroute 04:00 — Config files: hosts, resolv.conf 05:00 — Debug a real outage 🔗 Networking cheat sheet: https://dargslan.com ◀ Previous: L05 — Packages ▶ Next: L07 — SSH #Linux #LinuxNetworking #DevOps 🔔 Subscribe for weekly IT insights: https://m.youtube.com/channel/UCv2QLrkCMSBljYG5XKd8IEA About Dargslan: We are dedicated to sharing high-quality, practical IT knowledge.
