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.　　电视剧《风声传奇》是华谊兄弟的年度谍战巨制，由金牌导演董志强执导，廖凡挑梁主演，刘威葳、张歆艺、胡可分饰剧中的李宁玉、顾小梦和新角色林迎春。此外，《借枪》中的“小菊”李乃文、田雨、胡海峰、宗平、冯恩鹤、海一天等演员也有不俗表现。陈文羽打断了陈启的话。2018-02-28 15:56:42The force of the collision between the two bodies is nothing more than the flower that this force urges to bloom.
