Is port 3014 dangerous?

We have no specific security note for port 3014. 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 3014, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3014'      # process listening on 3014
sudo lsof -nP -i :3014

macOS

sudo lsof -nP -i :3014

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3014 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3014
netstat -ano | findstr :3014

From another machine

nmap -p 3014 -sV <host>
sudo nmap -sU -p 3014 <host>
nc -zv <host> 3014

Block it in the firewall

sudo ufw deny 3014/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3014" -Direction Inbound -LocalPort 3014 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3014 used for?

Port 3014 is assigned by IANA to broker_service (Broker Service), broker-service (Broker Service IANA assigned this well-formed service name as a replacement for "broker_service".).

Is port 3014 TCP or UDP?

Port 3014 is registered for TCP and UDP.

Is it safe to open port 3014?

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 3014 is open?

On Linux run "ss -ltnup 'sport = :3014'", on macOS "lsof -nP -i :3014", and on Windows "netstat -ano | findstr :3014" to see the local process. From another machine, "nmap -p 3014 <host>" shows whether it is reachable.
