TCPI/IP network stack simulator implemented in C. The simulator implements Basic Layer 2 (MAC Addresses, Arp) and Layer 3 (Routing , IPs) functionality.
Implementation works with Linux and MacOS
- make >= 4.1 (Linux, Mac)
- Clone this repo.
- Make a build directory in the top level directory:
mkdir build && cd build - Compile:
make - Run it:
./test.
$./test
