This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.年前的科学家塞斯刚刚发明一台能传送物体的“电动传送机”，这台机器能将物体分解，传送完成后再自动合成还原。兴奋不已的塞斯决定亲自体验一下电动传送，于是，他进入了传送仓。不幸的是，一只苍蝇这时也飞进了传送仓，于是，在机器将分解后的塞斯的分子再合成时，将苍蝇的分子也合成到了塞斯的体内。塞斯成了拥有一半苍蝇基因的蝇人......13岁的内特·福斯特（Nate Foster）是一个不受欢迎的中西部孩子，他幻想着成为百老汇音乐巨星。然而，与此同时，内特甚至无法在中学的戏剧作品中扮演一个像样的角色，在合唱团中扮演一棵树，而不是他渴望的主角。然而，当他和他最好的朋友利比在父母不知情的情况下策划了一次大胆的纽约之旅，为《丽洛与斯蒂奇：音乐剧》试镜时，内特可能即将实现他毕生的梦想。但首先，他必须克服一系列滑稽的障碍，这些障碍在每一个滑稽的转折点都会给他的百老汇冒险带来灾难。
