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.Has the landlord summed up　　2004年2月9日，沈浩作为安徽省第二批选派到农村任职干部来到了小岗村。自从实行大包干以后，由于种种原因，小岗村是“一夜越过温饱线，二十年没跨过富裕坎”。在沈浩到任之前的十年间，曾有五六名县乡干部先后到小岗村挂职任书记，却并没有让小岗村人满意。这更加激发他去实现自己的梦想，小岗村给他带了希望，去一个实现自我价值的地方。他们始终不知道的是，众人此时都处于一场梦境之中。　　遭敌反扑“围剿”失败后，韦拔群到广州。进入广东农讲所学习。后他返回东兰，也建立农讲所，教育、组织农民起来进行革命。
