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.　　周自横的妻子爱慕虚荣，抛夫弃子出国了。周自横为了守护心爱的杨白，主动要求下放到五七干校当医生。夏博文非常痴爱杨白，生怕失去，像供奉女神般地无微不至地照顾，洗衣做饭，帮她嗑瓜子仁暖被窝，甚至卖血换钱只为杨白买唱机听戏……种种“情”“爱”时时感动着杨白同时又折磨压迫着她，“离婚”二字始终话到嘴边却无法说出口……圣诞假期临近，居住在悉尼的格蕾丝和丈夫亚当及她的妹妹李前往澳大利亚北部——一个有鳄鱼出没的生态公园度假。公园内人潮攒动，欢乐气氛四处蔓延。这三个酷爱冒险的人相中了死水巴里河，于是决定次日向那里进发。他们错过了开往巴里河的游船，于是乘坐当地人吉姆的摩托艇驶往目的地。风和日丽，清爽时节，他们一心欣赏优美的自然风光，却完全忽视危险的存在。突然，小船遭到鳄鱼袭击，吉姆落水，格蕾丝他们就这样被困在了这个隔绝之地。
