To simulate the routings in Linux—core—common open research emulator

http://www.segurancaremota.com.br/2014/01/simular-roteamentos-no-linux-com-core.html

If you are looking for an environment light, practical and efficient to simulate networks, this environment is the core.

Best of all is that if all goes well, it 's just save the configuration files (default quagga) and up to its routers.

With this system, you can train your skills with networks in an environment totally safe.

So we go to the "hands - on" and install the system. I made a "compiled" after reading the documentation in the official site - http://www.nrl.navy.mil/itd/ncs/products/core

The instructions will follow shortly after the video, but remember, I
did this article in a Linux Kali (Debian), so if you'll do in other
distribution there may be some variation. In the Fedora also worked
perfectly.
