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.这一段饭，他也吃的比往常多。南洋是利益的根本，美洲是未来的希望，他哪个都不愿丢。鲍勃是一个秘密特工，身手矫健的他曾经为CIA立下了汗马功劳。他曾经单枪匹马闯进匪巢，直取匪首的脑袋；他曾经阻止恐怖分子在纽约安放炸弹；他还曾经截堵住毒贩、逮到过通缉犯。在CIA高层的眼中，鲍勃是一个上天下地，无所不能的超级特工。当鲍勃没有任务的时候，他会带起傻乎乎的黑框眼镜回到家中，过上普通人的生活。他现在准备退休了，所以搬到了现在的住所--女朋友吉莉安家的隔壁。山田洋次执导，桥爪功、吉行和、妻夫木聪、苍井优等出演的[家族之苦]确认拍续集，原卡司会回归。续篇将继续以喜剧形式讲述这家人之间的羁绊，据悉续集会涉及 “死亡”。影片将于2017年初夏在日本上映。
