对练姐姐负情，对师门辜恩的卓一航只能枯坐孤峰上，苦守着优昙仙花。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.“将军农民”甘祖昌解放后始终不忘让乡亲们都过上好日子的庄严约定，毅然请辞职务，带着妻子龚全珍和孩子回乡，带领乡亲们艰苦奋斗，改变家乡落后面貌Elf=ELF ('001')When traveling on icy and muddy roads, the top speed is 30 kilometers per hour.风景如画的桂林，壮族群众刘二刘三姐兄妹，与老渔夫、阿牛、舟妹住在一起亲如一家，过着勤劳幸福的生活。刘三姐和姑娘们喜欢在山上边采茶边唱歌。地主莫怀仁霸占茶山禁止百姓采茶，但乡亲们在刘三姐的鼓舞下拔掉了禁止采茶的牌子。莫怀仁气急败坏，又想禁止百姓唱歌。刘三姐与莫怀仁打赌，只要他在对歌中取胜，就可以禁歌。莫怀仁请来秀才与刘三姐对歌。百姓纷纷前来观看。刘三姐机敏过人，用山歌战胜了对手，莫怀仁狼狈逃走。但他不甘失败，又出毒计，把刘三姐抢到家中百般威胁，刘三姐坚贞不屈，阿牛勇敢地闯进莫家将刘三姐救走，莫怀仁带领家奴乘船追赶，百姓帮助刘三姐逃走。刘三姐和阿牛用山歌表白了彼此心意。封建官府下令禁歌，刘三姐带领乡亲们用歌声进行反抗，但在封建黑暗势力的压迫下，刘三姐被迫离开。但她继续在新的地方，用自己的歌声鼓舞民众，唤起大家与封建势力做斗争。每个中国人都知道，在台湾还有一座故宫博物院，号称世界五大博物馆之一。台北故宫中65万件艺术珍品，其中92%的文物来自于北京紫禁城的清宫遗存，是国之重器，国之瑰宝。60年前，它们漂洋过海落户台湾，整整60年的两岸隔阂，对13亿大陆国人而言，它们依旧很神秘。
