Extended TCP/IP Stack In Linux: Netfilter Hooks and IP Table

https://www.amazon.com/gp/product/1118887735

The chapter about debugging is rather outdated - it describes LKCD/lcrash environment but all new kernels have kexec/kdump facility and 'crash' is the preferred debugger for those vmcores. Maybe 2.4 kernels and lkcd are still relevant for embedded Linux (2.4 has a smaller memory footprint), I am mainly interested in normal systems.
