03 Check it

Which program uses port 6502, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6502'      # process listening on 6502
sudo lsof -nP -i :6502

macOS

sudo lsof -nP -i :6502

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6502 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6502
netstat -ano | findstr :6502

From another machine

nmap -p 6502 -sV <host>
sudo nmap -sU -p 6502 <host>
nc -zv <host> 6502

Block it in the firewall

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 6502 is open?

On Linux run "ss -ltnup 'sport = :6502'", on macOS "lsof -nP -i :6502", and on Windows "netstat -ano | findstr :6502" to see the local process. From another machine, "nmap -p 6502 <host>" shows whether it is reachable.
