  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 6506, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6506'      # process listening on 6506
sudo lsof -nP -i :6506

macOS

sudo lsof -nP -i :6506

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6506 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6506
netstat -ano | findstr :6506

From another machine

nmap -p 6506 -sV <host>
sudo nmap -sU -p 6506 <host>
nc -zv <host> 6506

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 6506 is open?

On Linux run "ss -ltnup 'sport = :6506'", on macOS "lsof -nP -i :6506", and on Windows "netstat -ano | findstr :6506" to see the local process. From another machine, "nmap -p 6506 <host>" shows whether it is reachable.
