In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.中原某市，市郊发生一起杀人案件，某公司董事长被人杀害尸体被肢解，市公安局接到报案后马上赶到案发现场，展开详细调查。随着调查的探入，一个庞大的黑神会团伙逐渐浮出水面，黑神会团为绑架勒索、杀人灭口。特警队临危授命，火速出击，欲将团伙一网打尽，但团伙的几个主要头目却突然失踪，究竟是谁泄露了机密？案情北后陷藏黑色真想，杀机暗诵，黑恶势力如影随形……Original by several English users, please abide by the specifications for reprinting.　　生活在纽约的POP艺术家姜勇基与同事乔安爱得轰轰烈烈，一次与罗仁静的偶遇给他留下了深刻的印象。Among the "waking up" experiencers, Ellie actually experienced a knock at the door by death because of a "failure" and never dared to talk about "suicide" again.讲述农民工；牛润田，为了救治患病的妻子，进城务工，一路上见义勇为，偶遇千金小姐于菲菲将其救下，并当了其私人保镖，因此也卷入了以李雄为首不法分子的纷争中，牛润田与坏人斗志斗勇，将于菲菲父女救下，法网恢恢疏而不漏，以李雄为首的不法分子最终被绳之以法。牛润田回到精武村把妻子病治好，并带领村民们搞生态养殖，共同致富。
