01 Security

Is port 2144 dangerous?

We have no specific security note for port 2144. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 2144, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2144'      # process listening on 2144
sudo lsof -nP -i :2144

macOS

sudo lsof -nP -i :2144

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2144 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2144
netstat -ano | findstr :2144

From another machine

nmap -p 2144 -sV <host>
sudo nmap -sU -p 2144 <host>
nc -zv <host> 2144

Block it in the firewall

sudo ufw deny 2144/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2144" -Direction Inbound -LocalPort 2144 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2144 used for?

Port 2144 is assigned by IANA to lv-ffx (Live Vault Fast Object Transfer).

Is port 2144 TCP or UDP?

Port 2144 is registered for TCP and UDP.

Is it safe to open port 2144?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 2144 is open?

On Linux run "ss -ltnup 'sport = :2144'", on macOS "lsof -nP -i :2144", and on Windows "netstat -ano | findstr :2144" to see the local process. From another machine, "nmap -p 2144 <host>" shows whether it is reachable.
