For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.韩平、叶红、文安三位刚刚步入社会生活的都市女性的事业、爱情、身世之谜诸方面的矛盾纠葛为主线，心充满机遇而又潜伏风险的现代都市生活为背景，反映她们的奋斗与失落、欢乐与感情，借以勾勒当代女性全新的生活理念与追求，在他们不同命运的轨迹中，伴随着各色各样的人物的渐次登场，展示了一幅幅色彩斑斓的当代都市生活的图景。同时，也表现了这种生活的丰富以及当代女性复杂的精神世界。王舒望和陆露在泰国相遇相识，经历了一系列惊心动魄的事情之后，相爱了。回国后，两人准备结婚，却遭到了双方家庭的反对。王舒望放弃了北京的事业，来到上海，开了一家陶瓷店，向陆露的家人证明自己可以给陆露更好的生活。陆露的父母依旧认为王舒望和陆露不合适，不同意他们的婚事。王舒望的异父异母姐姐赵燕也多次来到上海，还和陆露的妈妈蒋妙音发生了争吵。这让两人的婚事再度拖延。陆露和王舒望的爱情不断经受着来自双方家庭的打击和考验。此剧被称为TVB版《蜗居》。Lucy Worsley's Nights At The Opera, a two-part series featuring Sir Antonio Pappano, will explore the history and music of key opera cities.马德录执着地摇摇头，坚持到：不会的，就是蒙大将军的佩剑。
