01 Security

Is port 4044 dangerous?

We have no specific security note for port 4044. Its risk depends on the program actually listening on it. General advice for other services services:

  • 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 4044, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4044'      # process listening on 4044
sudo lsof -nP -i :4044

macOS

sudo lsof -nP -i :4044

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4044 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4044
netstat -ano | findstr :4044

From another machine

nmap -p 4044 -sV <host>
sudo nmap -sU -p 4044 <host>
nc -zv <host> 4044

Block it in the firewall

sudo ufw deny 4044/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4044" -Direction Inbound -LocalPort 4044 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4044 used for?

Port 4044 is assigned by IANA to ltp (Location Tracking Protocol).

Is port 4044 TCP or UDP?

Port 4044 is registered for TCP and UDP.

Is it safe to open port 4044?

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 4044 is open?

On Linux run "ss -ltnup 'sport = :4044'", on macOS "lsof -nP -i :4044", and on Windows "netstat -ano | findstr :4044" to see the local process. From another machine, "nmap -p 4044 <host>" shows whether it is reachable.
