Is port 2283 dangerous?

We have no specific security note for port 2283. 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 2283, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2283'      # process listening on 2283
sudo lsof -nP -i :2283

macOS

sudo lsof -nP -i :2283

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2283 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2283
netstat -ano | findstr :2283

From another machine

nmap -p 2283 -sV <host>
sudo nmap -sU -p 2283 <host>
nc -zv <host> 2283

Block it in the firewall

sudo ufw deny 2283/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2283" -Direction Inbound -LocalPort 2283 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2283 used for?

Port 2283 is assigned by IANA to lnvstatus (LNVSTATUS).

Is port 2283 TCP or UDP?

Port 2283 is registered for TCP and UDP.

Is it safe to open port 2283?

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 2283 is open?

On Linux run "ss -ltnup 'sport = :2283'", on macOS "lsof -nP -i :2283", and on Windows "netstat -ano | findstr :2283" to see the local process. From another machine, "nmap -p 2283 <host>" shows whether it is reachable.
