Assuming English isn't your first language... Did you look here? http://netcat.sourceforge.net/ Life's more painless for the brainless.

If you tell me where you are located at I can send you the want ad's. Not sure having been fired is too good on a resume. See, if you try to hack your corporate lan you will end up being fired. We usually don't try to help people do stupid stuff. You have to do that on your own. I read it wrong and answer it wrong too. So get off my case you peanut.

Even if you just try to scan the network, most probably you will be terminated and sent to jail in worst case if get caught. Proper way is check with the network administrator on what is the procedure to have Internet access.
