  • 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 24004, and is it reachable?

Linux

sudo ss -ltnup 'sport = :24004'      # process listening on 24004
sudo lsof -nP -i :24004

macOS

sudo lsof -nP -i :24004

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 24004 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 24004
netstat -ano | findstr :24004

From another machine

nmap -p 24004 -sV <host>
sudo nmap -sU -p 24004 <host>
nc -zv <host> 24004

Block it in the firewall

sudo ufw deny 24004/tcp                                         # Linux (ufw)
