Is port 3214 dangerous?

We have no specific security note for port 3214. 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 3214, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3214'      # process listening on 3214
sudo lsof -nP -i :3214

macOS

sudo lsof -nP -i :3214

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3214 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3214
netstat -ano | findstr :3214

From another machine

nmap -p 3214 -sV <host>
sudo nmap -sU -p 3214 <host>
nc -zv <host> 3214

Block it in the firewall

sudo ufw deny 3214/tcp                                         # Linux (ufw)

Is port 3214 TCP or UDP?

Port 3214 is registered for TCP and UDP.

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 3214 is open?

On Linux run "ss -ltnup 'sport = :3214'", on macOS "lsof -nP -i :3214", and on Windows "netstat -ano | findstr :3214" to see the local process. From another machine, "nmap -p 3214 <host>" shows whether it is reachable.
