洪霖这才变色，忍气问道：晚辈并非逼迫，乃是诚心求娶，何故不问皂白就拒绝？世家大族亦有良人，一定认准寒门小户，难道寒门小户养出来的都是高洁之人？晚辈看这清南村里品性鄙陋、贪婪不讲理的不知有多少，也并非都如传闻那般纯朴实在。Disk.startup ();15.5 Night blindness treatment is ineffective and unqualified.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.Some people may have embarked on a one-way trip to death 1-3 months in advance, during which some changes will occur.王穷想了一下，微笑上前道：既然点到下官，下官便说几句实话，希望能对案情有所助益。
