Is port 2524 dangerous?

We have no specific security note for port 2524. 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 2524, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2524'      # process listening on 2524
sudo lsof -nP -i :2524

macOS

sudo lsof -nP -i :2524

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2524 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2524
netstat -ano | findstr :2524

From another machine

nmap -p 2524 -sV <host>
sudo nmap -sU -p 2524 <host>
nc -zv <host> 2524

Block it in the firewall

sudo ufw deny 2524/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2524" -Direction Inbound -LocalPort 2524 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2524 used for?

Port 2524 is assigned by IANA to optiwave-lm (Optiwave License Management).

Is port 2524 TCP or UDP?

Port 2524 is registered for TCP and UDP.

Is it safe to open port 2524?

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 2524 is open?

On Linux run "ss -ltnup 'sport = :2524'", on macOS "lsof -nP -i :2524", and on Windows "netstat -ano | findstr :2524" to see the local process. From another machine, "nmap -p 2524 <host>" shows whether it is reachable.
