What options from the nmap manual have you tried?

I have something that I've deployed here, but it is very cut-down in the information it returns, so it might not be what you want. What is your eventual goal? Is it:-
  • Find all ports open on a whole range
  • Find devices that are up in a range
  • Find which devices are not offering a particular port or are down
  • Something else?

There is hopefully a neat tool to save you some work, but you need to be clear what your goal is first.



Kind regards,
Robin
