Eric Hughes was plagued with what, at first, loked like a DOS on his system. As it turns out, he was the lucky renter of an IP address that a busy P2P net believed was a willing participant. After being pounded for days and his firewall logs busting at the seams, he opted for a new DHCP-assigned IP address. Unfortunately, many ISPs aren't terribly responsive to such requests, so he took matters into his own hands & changed his MAC address. Release & renew and bingo...no more nasty UDP trash-o-grams filling his logs.
