nmap -sn is likely to be a good starting point. If you know a port that is open, then you can try nmap -sS/-sU -p port host where -sS selects a TCP SYN scan and -sU selects a UDP scan, -p specifies the port, and host is what it says on the tin. For example, a typical host would probably give reasonable results for: $ nmap -sS -p 22,3389 192.0.2.1 That will check the default SSH and Microsoft RDP ports on 192.0.2.1. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
