Is port 3084 dangerous?

We have no specific security note for port 3084. 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 3084, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3084'      # process listening on 3084
sudo lsof -nP -i :3084

macOS

sudo lsof -nP -i :3084

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3084 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3084
netstat -ano | findstr :3084

From another machine

nmap -p 3084 -sV <host>
sudo nmap -sU -p 3084 <host>
nc -zv <host> 3084

Block it in the firewall

sudo ufw deny 3084/tcp                                         # Linux (ufw)

What is port 3084 used for?

Is port 3084 TCP or UDP?

Port 3084 is registered for TCP and UDP.

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 3084 is open?

On Linux run "ss -ltnup 'sport = :3084'", on macOS "lsof -nP -i :3084", and on Windows "netstat -ano | findstr :3084" to see the local process. From another machine, "nmap -p 3084 <host>" shows whether it is reachable.
