Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP? The process of a SYN flooding attack.纵火、凶杀、绑架、制毒、抢劫……为打击犯罪分子的嚣张气焰，公安部特成立十几个特别案件侦破组，分赴大江南北、长城内外，专攻大案、要案和重案。包公奇案之双城记初始扑朔迷离，错综复杂，但包公厉眼如炬，洞察秋毫，往往从蛛丝马迹入手，调查取证为据，排除干扰势力，巧用智谋，最终真相大白，使罪犯无所遁形……　　为了帮丈夫洗脱罪名，宁小燕忍下心中的痛毅然挺身帮助秋犁东山再起。最终，两人在长辈们的大度大爱和兄弟姐妹们的纯真亲情感召和抚慰下，深刻感悟到夫妻一场的弥足珍贵，捐弃前嫌，重新走到一起。1985-92播出7季，还拍了两部电视电影的ABC老剧《百战天龙 MacGyver》，被CBS接手翻拍。MacGyver在原剧中是个不喜用枪的人，但却能用一把瑞士刀等东西解决各种事件。CBS对本剧的关注度很高。新版主演会年轻10年，讲述20多岁的MacGyver被招入一个隐秘的部门，剧中会解释他是如何学到一身如何解決难题的不同技能。
