03 Check it

Which program uses port 32483, and is it reachable?

Linux

sudo ss -ltnup 'sport = :32483'      # process listening on 32483
sudo lsof -nP -i :32483

macOS

sudo lsof -nP -i :32483

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 32483 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 32483
netstat -ano | findstr :32483

From another machine

nmap -p 32483 -sV <host>
sudo nmap -sU -p 32483 <host>
nc -zv <host> 32483

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 32483 is open?

On Linux run "ss -ltnup 'sport = :32483'", on macOS "lsof -nP -i :32483", and on Windows "netstat -ano | findstr :32483" to see the local process. From another machine, "nmap -p 32483 <host>" shows whether it is reachable.
