Is port 2934 dangerous?

We have no specific security note for port 2934. 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 2934, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2934'      # process listening on 2934
sudo lsof -nP -i :2934

macOS

sudo lsof -nP -i :2934

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2934 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2934
netstat -ano | findstr :2934

From another machine

nmap -p 2934 -sV <host>
sudo nmap -sU -p 2934 <host>
nc -zv <host> 2934

Block it in the firewall

sudo ufw deny 2934/tcp                                         # Linux (ufw)

What is port 2934 used for?

Port 2934 is assigned by IANA to 4-tieropmcli (4-TIER OPM CLI).

Is port 2934 TCP or UDP?

Port 2934 is registered for TCP and UDP.

Is it safe to open port 2934?

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 2934 is open?

On Linux run "ss -ltnup 'sport = :2934'", on macOS "lsof -nP -i :2934", and on Windows "netstat -ano | findstr :2934" to see the local process. From another machine, "nmap -p 2934 <host>" shows whether it is reachable.
