  • 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 5744, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5744'      # process listening on 5744
sudo lsof -nP -i :5744

macOS

sudo lsof -nP -i :5744

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5744 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5744
netstat -ano | findstr :5744

From another machine

nmap -p 5744 -sV <host>
sudo nmap -sU -p 5744 <host>
nc -zv <host> 5744

Block it in the firewall

sudo ufw deny 5744/tcp                                         # Linux (ufw)

Is port 5744 TCP or UDP?

Port 5744 is registered for TCP and UDP.

Is it safe to open port 5744?

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 5744 is open?

On Linux run "ss -ltnup 'sport = :5744'", on macOS "lsof -nP -i :5744", and on Windows "netstat -ano | findstr :5744" to see the local process. From another machine, "nmap -p 5744 <host>" shows whether it is reachable.
