If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.Arcade Game Collection 194 brings together classic arcade games, The game includes very famous and classic masterpieces such as: Three Kingdoms War, Three Kingdoms, Dinosaur Age, Famous Generals, Street Fighters, Round Table Knights, Fast Strike Cyclone, Dungeons and Dragons, etc., king of fighters, Alloy Warhead, Caijing 1945, Horcrux, Shuangjielong, Snow Mountain Brothers, Magic Zone, Green Corps, Real Fast Strike, Soul, Hungry Wolf, Yuehua Swordsman, Dinosaur Age, Famous Generals, etc.或者与我尹旭反抗暴秦，我当你是兄弟，竭尽全力让维护你。何永强坐在轿车内，没想到一切都这么巧，一切都这么快。该剧并不是写给青少年的校园剧，而是写给我们大家的职场剧，和以往的校园剧从学校外面窥探学校和老师的方式不同，将直击校园内部的我们不熟悉的露骨真相。 徐玄振在剧中饰演私立学校临时老师高荷娜，作为没有资历的菜鸟老师，她进入的却是以教学出色闻名的大峙洞私立高中，被大家认为是空降兵和说谎精，就这样踏出了社会生活的第一步。 罗美兰饰演学校升学部部长朴成顺。她在学生面前是技高于人的“疯狗”，是典型女强人系列的“工作狂”。她是大峙洞学校的入学负责人。为寻找失踪的丈夫贺五洲，31岁的夏白露带着5岁儿子来到北京，开始了北漂生涯。因为租房子她遇到了陪读的杜芬芳，又因做小时工结识了来照顾怀孕女儿的安和平。安和平是贺五洲的前妻，而杜芬芳的丈夫正是告发贺五洲挪用公款的人。在服装批发市场夏白露遇到了不打不相识的挚友，创造了销售奇迹挖到了第一桶金，在求学的过程中，她邂逅了意外的感情，当她刚刚在北京找到立足之地时，贺五洲的意外出现让尘封的秘密一一揭开，赌瘾已深贺五洲四处作孽，使三个家庭陷入危机。坚韧的夏白露并没有被生活击败，她的精神打动了大家，在大家的帮助下，她开始了创业的一步。慢活干探丁志摩带领的「杂项调查小队」(ME)，专门处理琐碎案件，与世无争。直至急进派「大肚婆」龙丽莎加入，争住做队中「尸王」，从此改写小队的命运。丽莎破案「无底线」，跟志摩的作风大相迳庭，两人在查案过程中一直互不咬弦。车奕晨为面子当差，却因失误致同袍伤残，自此散漫成性。他在ME却重遇旧情人谷芝晴，并与警队小鲜肉李俊基，展开三角关系。一次行动，揭露志摩多年秘密，加上奕晨之失误，令丽莎陷于生死关头……
