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.一颗子弹出膛，两世命运流转。纨绔富二代孙祺龙（魏大勋饰）回到了1936年的旧上海，传奇厨师张志刚（魏大勋饰）却来到了2016年，两人竟互相带着对方的身份和命运交换穿越了80年？传家宝的秘密，爱与恨的纠葛，一切谜题静待解答。且笃定时空万变，唯爱不变！汪魁坐在马上哈哈大笑道：胡钧，你可吃大亏了。两个性格迥异的女孩因为一次青春的叛逆结缘，陆可和沈思怡成为了彼此最重要的朋友。但因为沈思怡霸道无理的性格，两个女孩在高考后的夏天彻底断交，沈思怡远赴国外。康家一家住在广州西关老屋已经几十年了，康伯（龚锦堂饰）、康婶（黄锦裳饰）生了四个儿子，分别是祁光（苏志丹饰）、祁宗（郭旭饰）、祁耀（彭新智饰）和祈祖（徐若琪饰），四个儿子最近都结婚了，老大阿光娶了个河南姑娘（丁玲饰）、老二阿宗娶了个本地姑娘（虎艳芬饰）、老三阿耀娶了个上海姑娘、老四阿祖更厉害，娶了个德国姑娘（郝莲露饰）。这下一屋子天南地北的人全集齐了，各地文化在此交融，地域、文化间的隔膜在这一大家庭里闹出不少笑话，康家几乎每天都是生活趣事。不用吩咐，蒲俊、苏岸等人已经在组织人打扫战场。
