Where can I learn about networking? (sopuli.xyz)

I tried to study a bit from beej.us and I appreciated the style of teaching, but ultimately thought it wasn't for me as it didn't go much into depth and focused more on creating C programs. Is there some source from where I can learn in a comprehensive yet easy to understand manner the fundamentals of computer networking, at least to the extent that is relevant for selfhosting?

Old school recommendation, but the O’reilly book “Network Warrior” is actually a good read. It walks through common networking technologies, explains why they’re needed and how they’re used. Provides an excellent foundation of knowledge.

If books are more to the OP's liking, some that I've read that I've found useful:

  • Building a Home Cybersecurity Lab
  • Deep Dive into Linux Networking: Configuring Firewalls, VPNs, and Secure Connections
  • The Home Network Manual
  • Home Networking Bible

ETA: One more. This is more of a start to finish kind of course but networking is definetly covered. Takes you from day one with your linux distro and a blank slate, all the way to scripting, all in easily digestible chapters: https://linuxupskillchallenge.org/

Ohhhhh, I'd forgotten about this. Good one.
