01 Security

Is port 4447 dangerous?

We have no specific security note for port 4447. 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 4447, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4447'      # process listening on 4447
sudo lsof -nP -i :4447

macOS

sudo lsof -nP -i :4447

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4447 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4447
netstat -ano | findstr :4447

From another machine

nmap -p 4447 -sV <host>
sudo nmap -sU -p 4447 <host>
nc -zv <host> 4447

Block it in the firewall

sudo ufw deny 4447/tcp                                         # Linux (ufw)

What is port 4447 used for?

Port 4447 is assigned by IANA to n1-rmgmt (N1-RMGMT).

Is port 4447 TCP or UDP?

Port 4447 is registered for TCP and UDP.

Is it safe to open port 4447?

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 4447 is open?

On Linux run "ss -ltnup 'sport = :4447'", on macOS "lsof -nP -i :4447", and on Windows "netstat -ano | findstr :4447" to see the local process. From another machine, "nmap -p 4447 <host>" shows whether it is reachable.
