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?

Honestly, Cisco still is king for this. Look for some CCNA training courses to get a proper education on networking. Just get the material, don’t worry about the exam.
YouTube, CBT Nuggets, and INE all have plenty of courses.
Yup. And the official training books are still a great resource for learning everything from the basics to more advanced stuff.
I bought an updated set a couple of years ago, and they still hold up.
I still reference my Cisco Press CCIE routing TCP/IP volume 1 and 2 from 2005
Network Chuck’s earlier videos are pretty good, especially the You Suck At… series.
Unfortunately he’s been pushing AI shit lately.
Network Chuck
They are archived for download at https://archive.org/details/NetworkChuck. That way you don’t have to jump through all of YT’s bs.
At least the AI-related videos of his I’ve seen were about running models locally, and for relatively legitimate use cases (training text-to-speech voices and commanding Home Assistant), so it could be worse.
Yeaaah was thinking the same… He got me into docker containers and I’m glad I did ! Nice and easy introduction :) but his last 10 or so videos are all about AI and stuff… ://
There’s lots of good stuff on YouTube, including from David Bombal and Jeremy Cioara. If you’re more of a listening-while driving person, years ago the Security Now podcast did a “how the internet works” series that gives a terrific overview of the TCP/IP stack (it’s from 2006, but it’s still very applicable). And if you like to read, Michael Lucas just released a “Networking for Sysadmins” book, which is excellent.
Hi! I really enjoy the THM service: https://tryhackme.com/module/networking They have a bunch of different modules to study. They do cater more to Cyber Security, but Networking is definitely included there!
If you search for “data communications and networking” you will find alot of learning materials.
Eg:
How I learned the most was building a home server and figuring out all the problems along the way. LAN, WAN, VPN, iptables, DNS…
