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.
《白发魔女传》是第一部使用新武侠剧风格的电视剧，矫枉必须过正，所以不管什么，都是越夸张越好，近乎腾云驾雾的轻功，几丈远的剑气，真气化作各种猛兽形状……这样的特效乍一看非常唬人，但是如果观众看多了，就会审美疲劳，发现其实相当华而不实，会有一种群魔乱舞的感觉。

She can change their lives, if they can change hers. But with only one embryo left, can Dan and Emily trust a teenage girl they barely know with their last chance to have a family?
