I have been using nmap as well. But nmap is not able to identify OS for many IP addresses, so I am trying to find another tool to use alongwith nmap. I have been strugling with xprobe2. If it interests anyone, you can check the issue I am facing here: https://www.linuxquestions.org/questions/showthread.php?p=5859188#post5859188
