Is port 3230 dangerous?

We have no specific security note for port 3230. 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 3230, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3230'      # process listening on 3230
sudo lsof -nP -i :3230

macOS

sudo lsof -nP -i :3230

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3230 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3230
netstat -ano | findstr :3230

From another machine

nmap -p 3230 -sV <host>
sudo nmap -sU -p 3230 <host>
nc -zv <host> 3230

Block it in the firewall

sudo ufw deny 3230/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3230" -Direction Inbound -LocalPort 3230 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3230 used for?

Port 3230 is assigned by IANA to sftdst-port (Software Distributor Port).

Is port 3230 TCP or UDP?

Port 3230 is registered for TCP and UDP.

Is it safe to open port 3230?

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 3230 is open?

On Linux run "ss -ltnup 'sport = :3230'", on macOS "lsof -nP -i :3230", and on Windows "netstat -ano | findstr :3230" to see the local process. From another machine, "nmap -p 3230 <host>" shows whether it is reachable.
