01 Security

Is port 3209 dangerous?

We have no specific security note for port 3209. 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 3209, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3209'      # process listening on 3209
sudo lsof -nP -i :3209

macOS

sudo lsof -nP -i :3209

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3209 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3209
netstat -ano | findstr :3209

From another machine

nmap -p 3209 -sV <host>
sudo nmap -sU -p 3209 <host>
nc -zv <host> 3209

Block it in the firewall

sudo ufw deny 3209/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3209" -Direction Inbound -LocalPort 3209 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3209 used for?

Port 3209 is assigned by IANA to netwkpathengine (HP OpenView Network Path Engine Server).

Is port 3209 TCP or UDP?

Port 3209 is registered for TCP and UDP.

Is it safe to open port 3209?

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 3209 is open?

On Linux run "ss -ltnup 'sport = :3209'", on macOS "lsof -nP -i :3209", and on Windows "netstat -ano | findstr :3209" to see the local process. From another machine, "nmap -p 3209 <host>" shows whether it is reachable.
