For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.刘若英和张柏芝原是流光速车队里的灵魂人物，两人搭档取得了无数的比赛冠军。然而，在一场关键比赛中，两 人突然失踪导致车队败北并由此解散。一年后，流光速车队的教练林志颖决定重组车队，并挖掘了身为出租车司机的汤唯……TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified.通过外部矛盾，也逐渐暴露了内部矛盾。事到如今，他再无别的办法，只亡命仰天大吼，救命。宅男意外穿进仙侠世界,秒变仙宗反派BOSS羽凌风,为摆脱炮灰厄运,拯救失足魔尊楚烨,开挂闯关开启漫漫洗白之路！
