You can see that the attacker will only have to send a few SYN packets every ten seconds or so to disable a specific port.

您会发现，攻击者只要每十秒钟左右发送几个syn包就可以禁用特定端口。

The problem that can occur with TCP is when a rogue client forges an IP packet with a bogus source address, then floods a server with TCP SYN packets.

当恶意客户机使用虚假的源地址来伪造一个 IP 报文时，TCP 就会出现问题了，这会大量 TCP SYN 报文攻击服务器。

youdao

The server allocates resources for the connections upon receipt of the SYN, then under a flood of SYN packets, eventually runs out and is unable to service new requests.

服务器在接收syn报文之前，要为连接分配资源，但是在大量产生SYN报文的情况下，最终会耗尽自己的资源，从而无法处理新的请求。
