Scan a Public Ip with Nmap
I'm a beginner and I would like scan a pc on another local network.
I am 192.168.1.4 (for exemple) and I would like scan my other pc (for exemple 192.168.1.2) at home from my laptop at my friend's house. I have the public ip of my pc but I don't know how to:
- connect my laptop to my local network at home
- find my pc on this local network (with nmap)
- which command use?
Thank you a lot for your help and sorry for my bad english
