克里斯·帕拉特将回归电视，出演新剧《终极名单》(The Terminal List，暂译)。剧集由安东尼·福奎阿执导，根据Jack Carr畅销小说改编，David DiGilio(《旅行者》)撰写剧本。这部惊悚剧讲述了海豹突击队全队在一次高风险的秘密任务中遭到伏击的故事。里斯(帕拉特饰)带着对那件任务的矛盾记忆，以及对自己过失的疑问回到了家。然而，随着新的证据浮出水面，里斯发现了对他不利的黑暗势力。范依兰也开心到：这下爹爹总算是放心了。哈哈就和普通男孩一样热情好动，他喜欢捣乱但也拥有一颗敏感柔软的心，对每一件事情都充满了好奇且很有表现欲，但也常常因此闯祸。哈小龙是哈哈最忠实的朋友兼搭档，总是无底线地支持哈哈，在哈哈闯祸之后努力帮忙，却总是会弄巧成拙，越帮越忙。SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.
