sudo ss -ltnup 'sport = :9183'      # process listening on 9183
sudo lsof -nP -i :9183

macOS

sudo lsof -nP -i :9183

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9183 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9183
netstat -ano | findstr :9183

From another machine

nmap -p 9183 -sV <host>
sudo nmap -sU -p 9183 <host>
nc -zv <host> 9183
