什么反 ddos​​ 安全系统 python 用于套接字 TCP 连接？

Question

More in detail, would like to know:

• what is the default SYN_RECEIVED timer,
• how do i get to change it,
• are SYN cookies or SYN caches implemented.

I'm about to create a simple special-purpose publically accessible server. i must choose whether using built-in TCP sockets or RAW sockets and re-implement the TCP handshake if these security mechanisms are not present.

Answer 1

What you describe are internals of the TCP stack of the operating system. Python just uses this stack via the socket interface. I doubt that any of these settings can be changed specific to the application at all, ie these are system wide settings which can only be changed with administrator privileges.
