Which program uses port 9992, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9992'      # process listening on 9992
sudo lsof -nP -i :9992

macOS

sudo lsof -nP -i :9992

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9992 -State Listen | Select LocalAddress, OwningProcess

netstat -ano | findstr :9992

From another machine

nmap -p 9992 -sV <host>
sudo nmap -sU -p 9992 <host>
nc -zv <host> 9992
