  • 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 3013, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3013'      # process listening on 3013
sudo lsof -nP -i :3013

macOS

sudo lsof -nP -i :3013

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3013 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3013
netstat -ano | findstr :3013

From another machine

nmap -p 3013 -sV <host>
sudo nmap -sU -p 3013 <host>
nc -zv <host> 3013

Block it in the firewall
