01 Security

Is port 2340 dangerous?

We have no specific security note for port 2340. 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 2340, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2340'      # process listening on 2340
sudo lsof -nP -i :2340

macOS

sudo lsof -nP -i :2340

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2340 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2340
netstat -ano | findstr :2340

From another machine

nmap -p 2340 -sV <host>
sudo nmap -sU -p 2340 <host>
nc -zv <host> 2340

Block it in the firewall

sudo ufw deny 2340/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2340" -Direction Inbound -LocalPort 2340 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2340 used for?

Port 2340 is assigned by IANA to wrs_registry (WRS Registry), wrs-registry (WRS Registry IANA assigned this well-formed service name as a replacement for "wrs_registry".).

Is port 2340 TCP or UDP?

Port 2340 is registered for TCP and UDP.

Is it safe to open port 2340?

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 2340 is open?

On Linux run "ss -ltnup 'sport = :2340'", on macOS "lsof -nP -i :2340", and on Windows "netstat -ano | findstr :2340" to see the local process. From another machine, "nmap -p 2340 <host>" shows whether it is reachable.
