Is port 9084 dangerous?

We have no specific security note for port 9084. 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 9084, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9084'      # process listening on 9084
sudo lsof -nP -i :9084

macOS

sudo lsof -nP -i :9084

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9084 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9084
netstat -ano | findstr :9084

From another machine

nmap -p 9084 -sV <host>
sudo nmap -sU -p 9084 <host>
nc -zv <host> 9084

Block it in the firewall

sudo ufw deny 9084/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 9084" -Direction Inbound -LocalPort 9084 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 9084 used for?

Port 9084 is assigned by IANA to aurora (IBM AURORA Performance Visualizer).

Is port 9084 TCP or UDP?

Port 9084 is registered for TCP and UDP and SCTP.

Is it safe to open port 9084?

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 9084 is open?

On Linux run "ss -ltnup 'sport = :9084'", on macOS "lsof -nP -i :9084", and on Windows "netstat -ano | findstr :9084" to see the local process. From another machine, "nmap -p 9084 <host>" shows whether it is reachable.
