No I don't know what bullshit program you use. We setup real networks to work on, so there's no need for simulation. But yes I can see where that would be useful if there isn't funding for a real setup.
Your the noob actually do you know what Packet Tracer is? Its not a packet grabbing program its a network simulation program that allows you to design and mange your own network web. So before you go insulting people do a little research.
