I’m stumped. I’ve hit a wall and this one’s an old one. Back in the day when I was taking networking courses, I always had a sinking feeling whenever my instructor started on this topic. Today as I struggle with mastering linux, I’ve hit the same wall, but this time I hope to bust through it.
Here’s the course I’m going through. Hope it helps you somewhere!
