Hi Drygdryg,

I'm tried to use your script to discovery my network device without luck. Could you help me?

First, make sure that you run the script as root. Try running nmap with the specified arguments manually:

sudo nmap -sS -O --osscan-guess -T4 -n 172.16.232.0/24

I am getting the same error. I tried running the command manually and it worked fine directly in nmap.
