Is port 2632 dangerous?

We have no specific security note for port 2632. 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 2632, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2632'      # process listening on 2632
sudo lsof -nP -i :2632

macOS

sudo lsof -nP -i :2632

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2632 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2632
netstat -ano | findstr :2632

From another machine

nmap -p 2632 -sV <host>
sudo nmap -sU -p 2632 <host>
nc -zv <host> 2632

Block it in the firewall

sudo ufw deny 2632/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2632" -Direction Inbound -LocalPort 2632 -Protocol TCP -Action Block  # Windows

What is port 2632 used for?

Port 2632 is assigned by IANA to irdg-post (IRdg Post).

Is port 2632 TCP or UDP?

Port 2632 is registered for TCP and UDP.

Is it safe to open port 2632?

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 2632 is open?

On Linux run "ss -ltnup 'sport = :2632'", on macOS "lsof -nP -i :2632", and on Windows "netstat -ano | findstr :2632" to see the local process. From another machine, "nmap -p 2632 <host>" shows whether it is reachable.
