01 Security

Is port 3231 dangerous?

We have no specific security note for port 3231. 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 3231, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3231'      # process listening on 3231
sudo lsof -nP -i :3231

macOS

sudo lsof -nP -i :3231

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3231 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3231
netstat -ano | findstr :3231

From another machine

nmap -p 3231 -sV <host>
sudo nmap -sU -p 3231 <host>
nc -zv <host> 3231

Block it in the firewall

sudo ufw deny 3231/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3231" -Direction Inbound -LocalPort 3231 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3231 used for?

Port 3231 is assigned by IANA to vidigo (VidiGo communication (previous was: Delta Solutions Direct)).

Is port 3231 TCP or UDP?

Port 3231 is registered for TCP and UDP.

Is it safe to open port 3231?

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 3231 is open?

On Linux run "ss -ltnup 'sport = :3231'", on macOS "lsof -nP -i :3231", and on Windows "netstat -ano | findstr :3231" to see the local process. From another machine, "nmap -p 3231 <host>" shows whether it is reachable.
