Is port 2447 dangerous?

We have no specific security note for port 2447. 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 2447, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2447'      # process listening on 2447
sudo lsof -nP -i :2447

macOS

sudo lsof -nP -i :2447

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2447 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2447
netstat -ano | findstr :2447

From another machine

nmap -p 2447 -sV <host>
sudo nmap -sU -p 2447 <host>
nc -zv <host> 2447

Block it in the firewall

sudo ufw deny 2447/tcp                                         # Linux (ufw)

04 FAQ
What is port 2447 used for?

Port 2447 is assigned by IANA to ovwdb (OpenView NNM daemon).

Is port 2447 TCP or UDP?

Port 2447 is registered for TCP and UDP.

Is it safe to open port 2447?

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 2447 is open?

On Linux run "ss -ltnup 'sport = :2447'", on macOS "lsof -nP -i :2447", and on Windows "netstat -ano | findstr :2447" to see the local process. From another machine, "nmap -p 2447 <host>" shows whether it is reachable.
