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.《蚵丰村》是导演龙吟的首部长片作品，讲述滨海渔村的故事，全片以16mm底片拍摄，除了呈现沿海渔塭的独特美感，也试图捕捉传统村舍与寺庙信仰幽远的在地气息。一如台湾岛本身杂揉多样的海国特色，这部片邀请到了不同背景与文化底蕴的创作者，包括俄罗斯摄影师Aley Elagin、捷克声音设计师Vojtech Zavadil、马其顿灯光师Vladimir Dimoski等人，卡司则由「国民老爸」喜翔带着新生代演员林禹緒、陈莘太同台飙戏。Rui Yi interviewed some parents who chose to cultivate their children's thinking ability.
