of a LINUX NETWORK STACK
The Linux kernel is in a military zone with
guaranteed punishments for all trespassers.
Let’s emulate the kernel and study
packet flow in the network stack.
Linux is a free operating system, and that’s a boon to all computer- savvy people. People like to know how the kernel works. Many books and tutorials are available, but until you have hands-on experience,
you won’t gain any solid knowledge. The Linux kernel is a highly secure and
powerful operating system kernel. If you try doing anything fishy, the kernel
will kill your program. Suppose your program tries to access any memory
location of the kernel, the kernel will send a SIGSEGV signal, and your
program will core-dump by a segmentation fault. Similarly, you might come
across many other examples of the kernel’s punishments.
