01 Security

Is port 2244 dangerous?

We have no specific security note for port 2244. 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 2244, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2244'      # process listening on 2244
sudo lsof -nP -i :2244

macOS

sudo lsof -nP -i :2244

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2244 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2244
netstat -ano | findstr :2244

From another machine

nmap -p 2244 -sV <host>
sudo nmap -sU -p 2244 <host>
nc -zv <host> 2244

Block it in the firewall

sudo ufw deny 2244/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2244" -Direction Inbound -LocalPort 2244 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2244 used for?

Port 2244 is assigned by IANA to nmsserver (NMS Server).

Is port 2244 TCP or UDP?

Port 2244 is registered for TCP and UDP.

Is it safe to open port 2244?

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 2244 is open?

On Linux run "ss -ltnup 'sport = :2244'", on macOS "lsof -nP -i :2244", and on Windows "netstat -ano | findstr :2244" to see the local process. From another machine, "nmap -p 2244 <host>" shows whether it is reachable.
