The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. 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.凌梓铭和程一是从小一起长大的好朋友，他们来自两个不算完整的家庭，凌梓铭从小和二姨一起生活，程一由奶奶抚养长大，也正因如此，两个男孩在情感上相互搀扶，一同长大。进入青春期的两个人，逐渐在心理上产生了变化，尚且年少的男孩们，根本不懂什么是“爱”，他们一次次的试探彼此，却一步步的渐行渐远……医学院医药学教授陆炳文最近心情很不好研究一种代号为RT4抗癌新药虽然已经取得重大突破但就距离成功只有一步之遥时候由于资金问题陷于停顿而更使陆炳文头疼与学术研究纠缠一起说不清家务事……Move传销公司总裁一番激励人心的演说，让晓秋决心加入传销，企图改变自己的人生！而担任空姐的晓夏，遭到一名客人摸了一把，晓夏忍气，技巧地让对方不敢再逾矩，坐在附近的威廉看在眼里，对这女生留下深刻印象。叶家大姐晓春还没嫁进许家，许家父母就已将晓春当媳妇使唤，严密监控着晓春的一举一动。单亲爸爸志勇面对沈默寡言、孤僻自闭的祖望，苦无对策，只好屡将责任丢给晓春，为了孩子的未来，晓春付出许多，和志勇一家人建立了深刻情谊。一日，惠雯与小女儿晓冬口角冲突，晓冬竟离家出走，没想到她居然跑去跟男友同居，面对叛逆的晓冬，惠雯烦恼不已，不知该怎样将她导回正轨...该剧是《不要单身要恋爱》的系列剧第二部。苞谷见大哥终于同意他留下，高兴地笑了，忙抬胳膊配合他们脱衣。
