Is port 2471 dangerous?

We have no specific security note for port 2471. 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 2471, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2471'      # process listening on 2471
sudo lsof -nP -i :2471

macOS

sudo lsof -nP -i :2471

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2471 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2471
netstat -ano | findstr :2471

From another machine

nmap -p 2471 -sV <host>
sudo nmap -sU -p 2471 <host>
nc -zv <host> 2471

Block it in the firewall

sudo ufw deny 2471/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2471" -Direction Inbound -LocalPort 2471 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2471 used for?

Port 2471 is assigned by IANA to seaodbc (SeaODBC).

Is port 2471 TCP or UDP?

Port 2471 is registered for TCP and UDP.

Is it safe to open port 2471?

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 2471 is open?

On Linux run "ss -ltnup 'sport = :2471'", on macOS "lsof -nP -i :2471", and on Windows "netstat -ano | findstr :2471" to see the local process. From another machine, "nmap -p 2471 <host>" shows whether it is reachable.
