  • 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 6144, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6144'      # process listening on 6144
sudo lsof -nP -i :6144

macOS

sudo lsof -nP -i :6144

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6144 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6144
netstat -ano | findstr :6144

From another machine

nmap -p 6144 -sV <host>
sudo nmap -sU -p 6144 <host>
nc -zv <host> 6144

Is port 6144 TCP or UDP?

Port 6144 is registered for TCP and UDP.

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.
