The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.徐文长用一种阴沉的神色望向杨长帆，你有这个胆魄么？呼……杨长帆也逐渐冷静下来，沉吸一口气，露出了与徐文长相同的神色，为了一个何永强，有必要如此么？凭你我两只蚂蚁，真的吃得动象么？运势。[Squat Belt: Selection of Weightlifting Belt and Strength Lifting Belt and Introduction of Weightlifting Shoes] [Original]战国时代，礼崩乐坏。周天子狩猎大典遇刺，七国诸侯与后妃臣公皆有嫌疑。危机四伏，波谲云诡，精心布局的阴谋环环相扣。战火烽烟，诸侯并起，大时代中，秉承理想与信仰的旷世奇才鬼谷子王蝉，踏上了勤王之路，与门生孙膑、庞涓、苏秦、张仪等壮志凌云之士，前赴后继，匡扶正义，拯救天下。　　多年后，韩梅梅和李雷，还能牵手吗？奥斯卡金像奖获奖导演戴维斯·古根海姆（《难以忽视的真相》《他叫我马拉拉》）带来新作《走进比尔：解码比尔·盖茨》。这部全新的三集纪录片探索了著名技术先驱、商业领袖和慈善家比尔·盖茨的思想和抱负。在辞去微软首席执行官职务之后，盖茨将时间和出色才智投入到解决一些世界上最持久的问题上，由此便开始了现代史上最伟大的职业生涯第二幕。该剧集深入并真实地描述了比尔·盖茨在人生历程中经历的成功和挫折，以前所未有的深度让我们了解了比尔·盖茨，他的乐观、好奇心和热情曾激发他对微软的初始愿景，现在也激励他为世界上一些最复杂的问题寻求解决方案。《走进比尔》记录了这些努力与个人时刻，采访了比尔和梅琳达·盖茨，以及他们的朋友、家人、慈善事业和商业上的合作伙伴，塑造了一个富于创新的真实的人物形象，在改变世界之后，他可能还将改变人们看待世界的方式。In short, there are still many people who have not reported the case for various reasons.
