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.　　凯丽早已对阿羿拼命工作，无暇顾及家庭产生不满。一日又因凯丽与前男友道别时被阿羿看到，两人误会加深。可惜阿羿此时需进营集训，更使凯丽对两人的感情感到心灰意冷，遂决定从阿羿的住所中搬出。在天下失序、列强割据的战乱时代，僧人祥庵将一名孤儿从中国带到了日本。孤儿名叫仔太郎，他背负着一个惊人的秘密。与祥庵失散后，孤苦无依的仔太郎带着爱犬飞丸前往赤池之国的万觉寺，在途中遇见了神秘剑士“无名”。仔太郎遭到追杀，危急时刻无名救了他一命。从此两人结伴同行。性格乖僻的浪人和紧闭心扉的少年虽然磕磕碰碰不断，但渐渐成了好朋友。
