01 Security

Is port 2532 dangerous?

We have no specific security note for port 2532. 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 2532, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2532'      # process listening on 2532
sudo lsof -nP -i :2532

macOS

sudo lsof -nP -i :2532

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2532 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2532
netstat -ano | findstr :2532

From another machine

nmap -p 2532 -sV <host>
sudo nmap -sU -p 2532 <host>
nc -zv <host> 2532

Block it in the firewall

sudo ufw deny 2532/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2532" -Direction Inbound -LocalPort 2532 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2532 used for?

Port 2532 is assigned by IANA to ovtopmd (OVTOPMD).

Is port 2532 TCP or UDP?

Port 2532 is registered for TCP and UDP.

Is it safe to open port 2532?

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 2532 is open?

On Linux run "ss -ltnup 'sport = :2532'", on macOS "lsof -nP -i :2532", and on Windows "netstat -ano | findstr :2532" to see the local process. From another machine, "nmap -p 2532 <host>" shows whether it is reachable.
