If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. 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.2. Each receiver analyzes the request and then either processes it or passes it down.这么想着，她便奇怪地问胡钧道：你们家没有佃户？若是你见了他们的日子。该剧讲述了从1997年至2014年十几年的跨度下，刘诗诗与郑恺饰演的男女主角从高中到社会，在理想与现实中迷茫、妥协与抗争的故事Poet Yu Xiuhua himself is a typical example of "life is not easy".又看看小葱，忽然轻声坚定地说道：我眼下不会定亲的，再过两年——不对，是三年，算上今年就是三年，过三年我再定亲。若是没有实际利益，韩信是不会轻易动兵的。
