Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).果然董翳和左明太想留住他，将东阿一带的船只全部收集到两个渡口，不留一舟，让尹旭无船可用。但是今天，任我行、向问天、令狐冲却是神情肃穆，抱着有去无回的决心，踏上这个黑木崖。一场围剿贩枪歹徒的行动在短短七分钟内结束，数名歹徒被击毙，头目许志海被生擒。任务完成的干净利落，但林河市公安局局长李健却忧心忡忡，边境线上接连发生涉枪大案，再不整治，后患无穷。按照李健的指示，林河市公安局侦查员张猛以犯人身份潜入监狱，准备从罪犯许志海身上挖出线索。 几经努力，张猛成功赢得了许志海的信任，但许志海对枪的事始终守口如瓶。一个偶然的机会，许志海抢夺垃圾车越狱，张猛毫不犹豫紧跟许志海登上垃圾车。逃亡途中，许志海被公安干警击毙，临终前，他嘱托张猛去俄罗斯的拉维斯克市找自己的哥哥许志强。KBS的一档新节目,于2011年6月4日首次播出,以邀请前辈歌手为主人公,后辈歌手用自己的风格改编其名曲来演唱(偶像歌手翻唱经典老歌)对抗这样的形式进行的节目.与《我是歌手》不同的是,没有淘汰,但不排除歌手因日程问题替换和暂时下车.同时段MBC播放《我们结婚了》,SBS播放《鲫鱼面包》。
