I dont know if you realize what this is actually doing, however its essentially attacking ( performing a dos ) on the IP you specify. It's illegal, though the chance of prosecution is low, but i could see your ISP limiting/cutting/banning you if it goes on. the better way to do it is to use a lag switch, network bridge, or router mod. If none of these then atleast put your router's ip, or another IP on your home network into nettools instead of attacking some random guy's server.
