Is port 2434 dangerous?

We have no specific security note for port 2434. 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 2434, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2434'      # process listening on 2434
sudo lsof -nP -i :2434

macOS

sudo lsof -nP -i :2434

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2434 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2434
netstat -ano | findstr :2434

From another machine

nmap -p 2434 -sV <host>
sudo nmap -sU -p 2434 <host>
nc -zv <host> 2434

Block it in the firewall

sudo ufw deny 2434/tcp                                         # Linux (ufw)

04 FAQ
What is port 2434 used for?

Port 2434 is assigned by IANA to pxc-epmap (pxc-epmap).

Is port 2434 TCP or UDP?

Port 2434 is registered for TCP and UDP.

Is it safe to open port 2434?

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 2434 is open?

On Linux run "ss -ltnup 'sport = :2434'", on macOS "lsof -nP -i :2434", and on Windows "netstat -ano | findstr :2434" to see the local process. From another machine, "nmap -p 2434 <host>" shows whether it is reachable.
