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).李敬文正无法可施，忽然李敬德飞快地跑到西厢耳房旁的一棵桂花树下，捡了根树枝，在地上捣腾了一会，也不知弄了些什么，跑过来对着青莲身上戳过去。1990年代初。为追求新生活，山村姑娘扣儿（赵明明 饰）告别青梅竹马的男友田牛（纪原 饰）来到他乡，结识开有一家小旅馆的赵鬼（张山 饰），后者给了她诸多生活上的帮助。田牛不甘被扣儿小瞧，立志创业，几番辛苦终于得到酿制樱桃酒的秘方，成功借此成为知名企业家，并改名田家兴。扣儿带赵鬼回 到家乡，不把赵鬼放在眼里的田家兴以为一定能把扣儿娶到手传宗接代，但见识过外面世界的扣儿并不愿做一心为男人而活的传统女人。少女时代泰妍将担任预计今年上半年播出的女团回归大战Mnet《Queendom 2》的主持人。Consumer Xu: Not for the time being.
