  • 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 3382, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3382'      # process listening on 3382
sudo lsof -nP -i :3382

macOS

sudo lsof -nP -i :3382

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3382 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3382
netstat -ano | findstr :3382

From another machine

nmap -p 3382 -sV <host>
sudo nmap -sU -p 3382 <host>
nc -zv <host> 3382

Block it in the firewall

sudo ufw deny 3382/tcp                                         # Linux (ufw)

What is port 3382 used for?

Port 3382 is assigned by IANA to fujitsu-neat (Fujitsu Network Enhanced Antitheft function).

Is port 3382 TCP or UDP?

Port 3382 is registered for TCP and UDP.

Is it safe to open port 3382?

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 3382 is open?

On Linux run "ss -ltnup 'sport = :3382'", on macOS "lsof -nP -i :3382", and on Windows "netstat -ano | findstr :3382" to see the local process. From another machine, "nmap -p 3382 <host>" shows whether it is reachable.
