Ok, so i tried to nmap a computer on the cable network here in my city.
It said the host seems down so I added the switches for zeroping and XMAS, now it says the host is up ...GOOD. but it just not proceeds anywhere and after some time I ctrl+c it to exit,
I assume that the box is behind a firewall and a PROXY. so is there a way to reach that (maybe by bypassing the proxy) box since i have root priviledges on that and still cannot remote access it.
Also if there is a documentation on bypassing the proxy server.
