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.Denial of service attack: An attacker intentionally causes a computer or network to fail to function properly by some means, thus failing to provide the required services to legitimate users or degrading the quality of service.何员外余光一扫，瞥眼道：还差5分。远方海天一线处，已经依稀看到了盖伦船的影子，与预计到达的时间几乎分毫不差。“板凳”是上海滩一个杂耍班小人物的名字。板凳这个人只求太太平平地生活，甚至浑浑噩噩地混日子。他原本心无信仰，胸无热血，与政治和革命更是从无瓜葛，毫不相干。他活着仅仅为了活着，哪怕苟且偷生，不惜蒙羞含耻。他一定能会给电影版张无忌一个结局。　　本剧以全新视角诠释医院、医生及患者。剧中的女主人公怀着做一名为患者说话的医疗诉讼专业律师的志向，克服各种困难成为住院医，全剧通过她的视角，站在患者的立场上，审视医院里的人间百态，从而引起观众的共鸣。此外
