It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.“这部推理小说超好看！”系列第二弹。 这部暗黑剧以生活在夜晚世界的男人之复仇为主轴，揭露了在日本的地下社会一面。有着惊人过往的中介商——女玄；为了丈夫远赴日本打工的中国女性；与陌生对象假结婚的中年男子——剧中三人交换相互境遇和想法的同时，上演一场爱恨情仇。《X特工》是一部惊悚悬疑文武兼备的电视连续剧。以第二次世界大战中国上海地下抗日组织为背景，讲述了国共两党共同抗击日寇可歌可泣的英雄事迹……1942年第二次世界大战进入了更加残酷的白热化阶段。美国军部截获日本军方给上海日本驻军一秘密电文，但由于日方采用的是一次性解码系统，美方无法破译，因此美方要求中方尽快找到日军解码本。于此同时由于叛徒的出卖，日军在上海“特高课”总部“梅机关”汪伪特务组织76号联手对中方上海抗日地下组织发动了突然袭击，一夜之间，国共在上海地下组织几乎损失殆尽，军统上海站接到重庆密令，立即启动潜伏多年的王牌特工，代号为“铁铲”。令其不惜一切代价找到日军的解码本，查出敌人这次清剿行动背后的阴谋，同时中共也启动了资深的特工代号为“冰山”。但由于上海地下党组织大部分被破坏，一时与“冰山”无法取得联系。于是中共延安总部指令，香港地下党派遣新的领导人，潜入上海，并特指示长期潜伏在日伪控制区的金牌特工，汪秋霞；立即协助中方特工，重新恢复我上海地下抗日组织，设法查清敌人清剿行动背后真正的十年前，卡莉、斯宾塞和弗雷迪退出了一部最具标志性的电视剧，他们在20多岁时面对生活的不确定性，重新开始了人生的新篇章。5.
