What is Security ModeUnconnected queue: In the three-way handshake protocol, the server maintains an unconnected queue that opens an entry for each client's SYN packet (syn=j), which indicates that the server has received the SYN packet, sends a confirmation to the client, and is waiting for the client's confirmation packet. The connection identified by these entries is in Syn_RECV state on the server. When the server receives the confirmation package from the customer, the entry is deleted and the server enters ESTABLISHED state.Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history.Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer.But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them from stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.　　●我本将心向明月，奈何明月照沟渠。日和从今年春天开始就是高中生了，更赞的是她好不容易说服妈妈让她一个人生活，正当日和像只快乐的小鸟前往租屋处时，确发现有人捷足先登!!原来是妈妈担心她自己一个人，所以特地找了儿时玩伴来陪她共同生活，问题奏志是男生啊，妈妈到底是哪根筋不对劲啊……下河？大苞谷听愣住了。Master Control End: The master control end is some hosts illegally invaded and controlled by attackers.
