From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Resources for learning Linux Networking (iptables, namespaces, firewall, NAT, interfaces...)? preferably text resources (books, articles, etc) (lemmy.ml)

Hi all,

I am looking for recommendations on resources to learn Linux networking. I am primarily hoping for text resources such as books, guides, blog series, articles, etc. I have trouble focusing on videos.

I am mainly targeting linux networking topics, such as how the linux networking stack works, and things like iptables, network namespaces, network interfaces, sockets, NAT, firewalls, internal IP-addressing, subnetting, routing, proxying, internal DNS, and anything that I may not know exists but is related to these concepts and linux networking in general.

Any recommendations?

That was honestly what I was trying, but I felt myself blindly following tutorials without understanding what any of those components are or doing. And searching individual terms was not good enough. The concepts seem intertwined, and searching the web only gave me surface level explanations that didn't cut it.

build some of your own projects then. For example, my router has split routing between sites that require no VPN and normal sites. Find a project to do that isn't covered by tutorials, or read manuals instead of tutorials

I've fallen in the same hole before. tbh in my experience you don't really learn much until things start breaking.
