This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.珠光璀璨该剧讲述了职场萌新记者程了与棋坛风云人物盛景初之间陪伴守护的治愈系甜恋故事，蕴含中华文化丰富内涵的创新题材搭配全新组合CP该剧讲述了抗战时期，以欧阳锋为首的一群爱国热血青年，与日寇及汪伪政府特务展开一系列斗争的故事"Then when you shot these 'dogs' with guns, how many shots did you need on average to kill one?"
