　　Compared with SYN cache method, SYN? Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).A couple hires a professional digger (underground structure explorer) to help them find their friends, who mysteriously disappeared in the subway.黑豹（邓光荣）是一名用高额金钱便可请得到而从未失手的职业侠盗。某夜，黑豹受政府内政部要员秋Sir（黄锦燊）重金邀请，偷取一个“银盒”，以试新装之保安系统。黑豹于是找来一班各有特殊技能的人来帮手，分别是嘉嘉（吴家丽）、孟波辉（梁家辉）、程仁（任达华）、Robert（张卫健）及黑豹的师妹青青（林青霞）。　　雯雯的妈妈（龚蓓苾 饰）带着她走进了一个有奶奶（张芝华 饰）、爸爸（金粮 饰）和哥哥（陈薪羽 饰）的新家，然而，雯雯随之面对的是排山倒海般的爱向她袭来，在这样的爱之下，婆婆和媳妇、儿子和父亲、丈夫和妻子、继母和儿子、母亲和女儿的矛盾交错冲击，雯雯的妈妈终于心力交瘁了，虽然她不顾一切地想要了解和帮助她的女儿，但这样的亲子关系最后仍然以难以捉摸的失败告终——雯雯选择将自己封闭在了一个完全由爸爸的童话故事《地下根娘》的想象世界中，她仍然在自己的绘画中穿越地心，借此逃避爸爸去世的事实，全家矛盾最终以奶奶的求神拜佛而激化，雯雯的妈妈带着她离家啦。 这时，小哥哥英勇出击，他首先参与了雯雯的寻找根娘Jiangsu Province
