Welcome to the most brutally honest Linux networking guide you’ll ever watch! No fluff, no corporate nonsense—just real-world lessons, painful truths, and a few horror stories from the trenches.
?️ What You’ll Learn:
✅ How Linux network interfaces actually work (no, eth0 isn’t always eth0 anymore!)
✅ Essential networking commands (ip link, ping, traceroute, dig)
✅ Why Predictable Network Interface Naming saved us from the Teaberry Shuffle
✅ How one bad DNS change can take down your network (ask Facebook)
✅ The Phantom Duplex Shuffle—when your NIC just decides to mess with you
✅ The most important rule when calling your ISP (Hint: It’s always been working perfectly for two years!)
? Featuring LIVE demos! Because nothing says “Chaos Manor” like watching networking in real-time.
⚠️ Warning: This video contains strong sysadmin energy, real IT pain, and absolutely no subnetting tutorials. Buy a book for that. ?
