The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.板栗暗叹了一声，知道周爷爷今日要定下孙女婿了，看这情形自己凶多吉少。该剧改编自欧阳墨心人气小说《到开封府混个差事》，讲述了鬼马少女金虔女扮男装进入开封府成为一名捕快，与展昭、公孙策、包拯、锦毛鼠、冰姬等人共同缉凶破案，并揭开一起巨大阴谋的故事。Yellow-green system: kudzu vine, amurense amurense, etc.大流行时期的爱情。 虽然现在并不是出去约会，结识某人并坠入爱河的最佳时机，但Key和Chen在增强的社区隔离中找到了彼此，并以让他们感到惊讶的方式建立了联系。 尽管大流行带来了种种限制，挑战甚至危险，当他们彼此了解时，一些非常特殊的事物开始在他们之间绽放。 在我们被迫彼此分开的时代，爱有力量连接我们吗？
