As shown in the above figure, the server side provides NTP service. Attacker sends an NTP monlist Request to the server, but its source IP address is not its own IP address, but the IP address of the target. After the server receives the request, it will send a Response message to Target (not Attacker). Since Reponse contains 600 time synchronization records with Server, which is much larger than Request and consists of many messages, amplification is realized.范亚父轻叹一声，似乎是在提醒项羽。On the morning he is set to star in a career-changing blockbuster film, an Irish actor trying to live down his rocky past confronts a series of devastating events that threaten his sobriety, his loved ones, and ultimately his life.故事是从一个离奇的婚礼开始：大明年间，秀丽的江南蒋州，孟大学士才貌绝世的女儿，孟丽君要出嫁了。她要嫁的是豪门皇亲刘捷的儿子，刘奎壁。可本该是喜上眉梢的新娘，却泪流满面，麻衣素服，这究竟是为了什么……传国玉玺在手，国力数倍于汉国，还要向刘邦称臣的话岂不是笑话？尤其是刘邦这样不自重，嚣张倨傲的情况下。The attacker first forged the address to initiate a SYN request to the server (can I establish a connection?) The server will respond with an ACK + SYN (Yes + Please confirm). The real IP will think that I did not send the request and did not respond. The server does not receive a response and will retry 3-5 times and drop the connection after waiting for a SYN Time (typically 30 seconds-2 minutes).
