01 Security

Is port 2441 dangerous?

We have no specific security note for port 2441. 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 2441, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2441'      # process listening on 2441
sudo lsof -nP -i :2441

macOS

sudo lsof -nP -i :2441

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2441 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2441
netstat -ano | findstr :2441

From another machine

nmap -p 2441 -sV <host>
sudo nmap -sU -p 2441 <host>
nc -zv <host> 2441

Block it in the firewall

sudo ufw deny 2441/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2441" -Direction Inbound -LocalPort 2441 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2441 used for?

Port 2441 is assigned by IANA to pvsw-inet (Pervasive I*net Data Server).

Is port 2441 TCP or UDP?

Port 2441 is registered for TCP and UDP.

Is it safe to open port 2441?

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 2441 is open?

On Linux run "ss -ltnup 'sport = :2441'", on macOS "lsof -nP -i :2441", and on Windows "netstat -ano | findstr :2441" to see the local process. From another machine, "nmap -p 2441 <host>" shows whether it is reachable.
