01 Security

Is port 2484 dangerous?

We have no specific security note for port 2484. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 2484, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2484'      # process listening on 2484
sudo lsof -nP -i :2484

macOS

sudo lsof -nP -i :2484

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2484 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2484
netstat -ano | findstr :2484

From another machine

nmap -p 2484 -sV <host>
sudo nmap -sU -p 2484 <host>
nc -zv <host> 2484

Block it in the firewall

sudo ufw deny 2484/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2484" -Direction Inbound -LocalPort 2484 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2484 used for?

Port 2484 is assigned by IANA to ttc-ssl (Oracle TTC SSL).

Is port 2484 TCP or UDP?

Port 2484 is registered for TCP and UDP.

Is it safe to open port 2484?

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. Bind the service to localhost or a private network, never to a public address.

How do I check if port 2484 is open?

On Linux run "ss -ltnup 'sport = :2484'", on macOS "lsof -nP -i :2484", and on Windows "netstat -ano | findstr :2484" to see the local process. From another machine, "nmap -p 2484 <host>" shows whether it is reachable.
