I need to test my nmap script, which crashes when many ports are open. So I need a script (python/bash) that opens n ports on a server.

How could I do that?

Thank you

  • Please show your code and explain the error clearly: how is it crashing ? – Anonymous Mar 22 '20 at 17:28

Perhaps use netcat(1) (command is nc) to listen on the ports of interest (it isn't called the swiss army knife of networking for nothing). If any ports are below 1024, you'd need to run it as root.
