Is port 2034 dangerous?

We have no specific security note for port 2034. 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 2034, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2034'      # process listening on 2034
sudo lsof -nP -i :2034

macOS

sudo lsof -nP -i :2034

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2034 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2034
netstat -ano | findstr :2034

From another machine

nmap -p 2034 -sV <host>
sudo nmap -sU -p 2034 <host>
nc -zv <host> 2034

Block it in the firewall

sudo ufw deny 2034/tcp                                         # Linux (ufw)

04 FAQ
What is port 2034 used for?

Port 2034 is assigned by IANA to scoremgr ().

Is port 2034 TCP or UDP?

Port 2034 is registered for TCP and UDP.

Is it safe to open port 2034?

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 2034 is open?

On Linux run "ss -ltnup 'sport = :2034'", on macOS "lsof -nP -i :2034", and on Windows "netstat -ano | findstr :2034" to see the local process. From another machine, "nmap -p 2034 <host>" shows whether it is reachable.
