01 Security

Is port 2146 dangerous?

We have no specific security note for port 2146. 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 2146, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2146'      # process listening on 2146
sudo lsof -nP -i :2146

macOS

sudo lsof -nP -i :2146

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2146 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2146
netstat -ano | findstr :2146

From another machine

nmap -p 2146 -sV <host>
sudo nmap -sU -p 2146 <host>
nc -zv <host> 2146

Block it in the firewall

sudo ufw deny 2146/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2146" -Direction Inbound -LocalPort 2146 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2146 used for?

Port 2146 is assigned by IANA to lv-not (Live Vault Admin Event Notification).

Is port 2146 TCP or UDP?

Port 2146 is registered for TCP and UDP.

Is it safe to open port 2146?

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 2146 is open?

On Linux run "ss -ltnup 'sport = :2146'", on macOS "lsof -nP -i :2146", and on Windows "netstat -ano | findstr :2146" to see the local process. From another machine, "nmap -p 2146 <host>" shows whether it is reachable.
