Mr-Pstar7/ZeroDoS — reverse-engineered prompt

Build me a simple C++ command line network testing tool for my own lab, not something meant to attack public sites. I want it to open lots of concurrent connections to a test server I control so I can learn about threading and connection handling. It should let me pass in a host, port, max sockets, and number of threads, plus optional timing settings like small delays and how often to print status updates.

Please make it easy to compile and run on Linux and Termux with g++. Add a help screen with example usage, and show live stats like active connections and basic progress. Put in strong safety limits so it only works on localhost or private network addresses by default, with clear warnings if someone tries anything else. If possible, include clean shutdown, input validation, and comments so a beginner can understand the code. Look up current docs online if you need to.
