Can someone tell me: where can i find TCP/IP stack in Busybox source code ?

Answer 1

Busybox does not contain a TCP/IP stack. It makes system calls to the operating system to do networking operations.

Here is a good starting place to read about the kernel side of things: Anatomy of the Linux networking stack.

Answer 2

In Unix-based Systems, the TCP/IP stack is actually built into the kernel, not user space, so Busybox doesn't actually implement it. If you want to actually find that stack, look in the Linux kernel that you will use with busybox. Many people choose to use the older (2.4) kernels because they are lighter weight than later ones.
