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.　　Peter和Nathan也将试图回到过去的生活中, Peter将拯救他人的生命, 但是这将使他和家族, 朋友产生隔阂,但是Peter将和一个"能力强大"的美丽女子坠入爱河, 这会让他发现生活真正的乐趣在于与人交流. 而Nathan每天都将对自己有新的发现,因为事实上他是Sylar.云青山道：其实进入巴蜀，若是由东向西正面走，确实必须要进入夷陵。田文洁与丈夫贺立群用了半生积蓄，购买了一栋新建公寓的楼房，对即将开始的新生活充满了美好的期待。
