The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.陈启一看，是爱丽丝打来的。为免涉足江湖恩怨情仇，玉云龙 （萧正楠饰） 与姐玉娇凤（简慕华饰）安份守己经营客栈生意，谁料云龙为重夺旧爱艾冰冰（汤洛雯饰）芳心毅然参加新晋英雄大赛，因而牵涉揭发东厂黑幕，被东厂的仇不群（黄智贤饰）收入监牢，娇凤救弟心切，暗中放风指客栈有隐世宝物，不群不单立即释放云龙，更派出左右手仇在心（陈凯琳饰）跟随云龙到客栈收取情报，此事亦引来各路隐世英雄一一涌现，各施奇谋，期间令一直寻找杀害双亲的在心发现真相，倒戈相向对付不群之余，更与云龙产生感情，决心一同改革武林，令本已奄奄一息的武林再现生气，但二人却陷入本是慈悲老人任我飞（姜大卫饰）筹谋已久的复仇大计……Dogs go and do singing and stuff.
