Is port 2284 dangerous?

We have no specific security note for port 2284. 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 2284, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2284'      # process listening on 2284
sudo lsof -nP -i :2284

macOS

sudo lsof -nP -i :2284

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2284 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2284
netstat -ano | findstr :2284

From another machine

nmap -p 2284 -sV <host>
sudo nmap -sU -p 2284 <host>
nc -zv <host> 2284

Block it in the firewall

sudo ufw deny 2284/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2284" -Direction Inbound -LocalPort 2284 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2284 used for?

Port 2284 is assigned by IANA to lnvmaps (LNVMAPS).

Is port 2284 TCP or UDP?

Port 2284 is registered for TCP and UDP.

Is it safe to open port 2284?

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 2284 is open?

On Linux run "ss -ltnup 'sport = :2284'", on macOS "lsof -nP -i :2284", and on Windows "netstat -ano | findstr :2284" to see the local process. From another machine, "nmap -p 2284 <host>" shows whether it is reachable.
