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?

    Most tutorials, even recent ones, reference iptables. Never seen nftables. One example is WireGuard guide.

        True; but many guides & tutorials that came out long after that still give their examples/instructions in iptables. Esp. those that involve ifup/ifdown/etc. scripts.

        (although nftables is considerably easier to read, IMHO)

      I’ve never seen nftables, or should I say never noticed nftables, when ever I’ve seen documentation it’s always referenced iptables, if it has mentioned nftables I’m guessing my brain just glossed over it. It’s kind of like with networking configuring with /etc/network/interfaces rather than with netplan or network manager or systems or ifup ifdown, or anything else I’ve missed
