何况现在六县附近全是龙且的军队，若是没有人引开龙且的注意，妻子和儿子想要平安离开无疑也是非常困难的。顾涧忙请他坐下，问道：周先生觉得黎章此去胜算如何？周先生对他抱拳道：将军，在下原本对西行只有五分把握，听了这黎章的安排，已经有八分胜算。尹旭暗赞一声，历史记载王离确实参与了巨鹿之战，自己知道不奇怪。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."No, it's all sent at home." Huang Jinbo told him, "Go out by yourself and stop that. Be careful."In an interview with the parents of Jiang Yang's expected primary school students, the students of the practice team heard a completely different voice from the school: the teacher's qualification was low, the teaching was not responsible, the children were allowed to cheat in exams in order to achieve results, the school had potential safety hazards, and junior high schools were set up at random... All kinds of problems surfaced. What kind of education do the students receive? Did school really follow the tenet of "everything for children"? The players were very worried.
