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.撂下一句：来日沙场上见真章。……寅时。方杰和方明是自幼丧母并相依为命的孪生兄弟，一根稻草定乾坤，尚显稚嫩的哥哥方杰牺牲自己出外打工养家糊口，一直供养弟弟读完公安大学。早在九十年代初，10币大案轰动全市，已成为苍海市刑警队长的方明在案犯追捕中，为掩护女同事陈静，不幸负重伤变成植物人。从这一刻起，本就暗恋方明的陈静决定为这份渺茫的情感守护一生。身为苍海市风云人物的汉通集团总经理方杰，仍象少时悉心照顾着弟弟。十年后，苍海市又响炸雷：十年前10案中的假币在一起抢劫银行运钞车案件中再次现身，植物人方明奇迹苏醒，并接手了此案。冥冥之中是命运驱使？也许十年前留下诸多悬疑的假币案向世人撒了弥天大谎？方明的苏醒带给自己和周围人几多惊喜几多愁：面对前妻朱敏的关心佯装不知而压抑自己，面对迷人女富商热情的追求顾虑重重而爱恨两难……这一切让看在眼里的陈静更加心痛方明的侦破工作迷雾重重、扑朔迷离；哥哥方杰一向顺手的生意也屡屡受挫，而且在他公司下属的工厂、娱乐城里频频出现制造伪钞的踪迹，妻子茹晓芊自10币案后就神秘地疯疯癫癫，是栽赃陷害？还是另有隐情……例如那腊肉，时间保存的越长，越是香味浓郁。小葱用食指点着自己鼻尖问道：我？那两个护卫用力点头，忐忑道：是……是将军。
