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.小葱忽然笑起来，对云影道：师傅，我娘说，你做的菜是大家闺秀，她做的菜是乡野村姑，各有风味。1948年，彼时战后的德国正处于重建阶段，东部和西部即将面临长期分裂对立的局面。沃尔夫家族的工厂历经四代传人，有着长达80年的历史。如今这个家族企业面对着复杂多变的环境局势，不得不在夹缝中求生存...Judgment: However, the quality of express packaging is still good for the moment.
