顾涧沉吟了一下，道：想是让他戴罪立功。In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. 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).第二更。而后将战舰上九成的火炮拆卸转移埋伏在岸上，并且留下八成兵力守卫安汶，余下两成兵力驾船出海，在北侧苏拉群岛绕道突袭肯达里。青木不敢相信地问：你说啥？马小六红着眼睛道：有人听桃花谷的差大爷说，玉米叫狼叼走了，吃的连骨头都不剩……郑老太太往后一倒，又一次晕了过去。影片讲述了安可带着男友关天去医院看病，可是男友进入手术室以后就再也没出来。焦急的安可开始寻找，她发现手术室里空无一人，而且整个医院里也变得空无一人。同时医院也开始发生各种怪事，太平间复活的阴尸、走廊里闪现的鬼影、地下车库里出现的怪物、男友电话里传来的求救声，整个医院仿佛就是人间地狱……　　在侦破过程中，杨大志面临着爱情、友情以及亲情的重大考验。作为廉署员工，他究竟能否舍情取义，发挥廉洁精神呢？
