Is port 2649 dangerous?

We have no specific security note for port 2649. 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 2649, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2649'      # process listening on 2649
sudo lsof -nP -i :2649

macOS

sudo lsof -nP -i :2649

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2649 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2649
netstat -ano | findstr :2649

From another machine

nmap -p 2649 -sV <host>
sudo nmap -sU -p 2649 <host>
nc -zv <host> 2649

Block it in the firewall

sudo ufw deny 2649/tcp                                         # Linux (ufw)

04 FAQ
What is port 2649 used for?

Port 2649 is assigned by IANA to vpsipport (VPSIPPORT).

Is port 2649 TCP or UDP?

Port 2649 is registered for TCP and UDP.

Is it safe to open port 2649?

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 2649 is open?

On Linux run "ss -ltnup 'sport = :2649'", on macOS "lsof -nP -i :2649", and on Windows "netstat -ano | findstr :2649" to see the local process. From another machine, "nmap -p 2649 <host>" shows whether it is reachable.
