SYN attack is a kind of DOS attack. 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.周菡心道，可我想住你家呢。Deep water torpedo (mine x 100)电视剧《爱的相对论》中，罗晋饰演的原野是名副其实的富二代，父亲是上市集团的总裁，事业成功，感情生活却异常混乱，不久前迎娶了足以做原野妹妹的第四个老婆。原野坚持过着自食其力的生活，本打算在和白领女友夏楠结婚后逃离纷争不断、毫无温暖可言的家，享受温馨的二人世界。偏偏事与愿违，因为某些原因他们不得不与专制的父亲、幼稚的小妈住在同一屋檐下。可他的麻烦也接踵而至，四个妈也因为不同的缘由相继纠缠到了一起，将他和夏楠搅入了五花八门的事端之中……谭云是望月镇小贵族谭家的少爷，但鸿蒙至尊转生之人需要受到生死刺激才能觉醒，所以谭云在起初的十六年一直是一个被人欺负鄙视的废柴。在婚礼中，谭云撞见未婚妻与司徒家少爷偷情并被殴打，在将死之时终于觉醒了鸿蒙至尊的记忆。The concept of content-based products, broadly speaking, is a product form that meets users' content consumption needs.
