Is it possible in Linux to prohibit the creation of sockets by programs that run as a specific user?
The user uploads the program to the server, runs it and uses the ports. How to forbid the user to use server ports, is there a possibility and is it possible at all?
I would like to allow the user only one port, a specific port.

Answer 1

If you forbid the user to open sockets, he will not be able to run any program that connects somewhere, it must also open a socket to open a session
