01 Security

Is port 2483 dangerous?

We have no specific security note for port 2483. 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 2483, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2483'      # process listening on 2483
sudo lsof -nP -i :2483

macOS

sudo lsof -nP -i :2483

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2483 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2483
netstat -ano | findstr :2483

From another machine

nmap -p 2483 -sV <host>
sudo nmap -sU -p 2483 <host>
nc -zv <host> 2483

Block it in the firewall

sudo ufw deny 2483/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2483" -Direction Inbound -LocalPort 2483 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2483 used for?

Port 2483 is assigned by IANA to ttc (Oracle TTC).

Is port 2483 TCP or UDP?

Port 2483 is registered for TCP and UDP.

Is it safe to open port 2483?

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 2483 is open?

On Linux run "ss -ltnup 'sport = :2483'", on macOS "lsof -nP -i :2483", and on Windows "netstat -ano | findstr :2483" to see the local process. From another machine, "nmap -p 2483 <host>" shows whether it is reachable.
