Ask HN: Best “Full-Stack” Developer Reference on Linux Networking?
At recent jobs, however, these have been taking place at a much lower level and requiring a deep knowledge of networking in the Linux kernel. I've found the transition difficult and also have found it difficult to find a unified reference for all things Linux networking. The ones I find are either too basic or targeted for SysAdmins.
What I would love to find is something in the style of a Beej's Guide to socket programming (https://beej.us/guide/bgnet/) but covering the following:
1. Overview of Linux networking, including firewalls and routing tables.
2. The lifecycle of a packet through the kernel from coming in "over the wire" through delivery to an application socket (and vice versa).
3. An overview of network interfaces, virtual network interfaces, and the utilities to set them up, tear them down, and configure them. Also covering things like TUN/TAP devices, VLANs, PVLANs, network namespaces, etc (targeted for developers).
4. An overview of all the linux tools to shape traffic (queuing disciplines, etc) and measure network performance.
I have cursory understandings of each of these, and have had such a hard time finding a universal reference (again, the same way Beej's Guide is the de-facto reference for socket programming). Many books that seem to cover the topic are decade(s) old. Thanks for any help.
