Is port 9284 dangerous?

We have no specific security note for port 9284. 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 9284, and is it reachable?

Linux

sudo ss -ltnup 'sport = :9284'      # process listening on 9284
sudo lsof -nP -i :9284

macOS

sudo lsof -nP -i :9284

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 9284 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 9284
netstat -ano | findstr :9284

From another machine

nmap -p 9284 -sV <host>
sudo nmap -sU -p 9284 <host>
nc -zv <host> 9284

Block it in the firewall

sudo ufw deny 9284/tcp                                         # Linux (ufw)

04 FAQ
What is port 9284 used for?

Port 9284 is assigned by IANA to visd (VERITAS Information Serve).

Is port 9284 TCP or UDP?

Port 9284 is registered for TCP and UDP.

Is it safe to open port 9284?

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 9284 is open?

On Linux run "ss -ltnup 'sport = :9284'", on macOS "lsof -nP -i :9284", and on Windows "netstat -ano | findstr :9284" to see the local process. From another machine, "nmap -p 9284 <host>" shows whether it is reachable.
