TCP - how to create your own package?

Question

C++ / C#

Good afternoon! How to create your own package in C ++ and what will it transfer?

Answer 1

C TCP usually does not work in packets. Work in streams or Streams. This is a normal level for an application programmer. And I almost do not know tasks other than student labs where someone suddenly needed a package as such.
There are plenty of examples. API: socket(), connect(), bind() ,listen().
Therefore, the author may need a fundamentally different protocol. Applied UDP. Or a more system IP, but the latter is more difficult to work with. OSes prohibit it directly. Through it, it is easy to arrange various Syn-Flood attacks. You need to somehow elevate privileges or use third-party libs.

Answer 2

Create and send - for example, in Python using the socket library. What will he send? - Well, what you put in it, it will transmit.
