what anti-ddos security systems python use for socket TCP connections?

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.

Solution

  • 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, i.e. these are system wide settings which can only be changed with administrator privileges.
