Is port 14001 dangerous?

We have no specific security note for port 14001. 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 14001, and is it reachable?

Linux

sudo ss -ltnup 'sport = :14001'      # process listening on 14001
sudo lsof -nP -i :14001

macOS

sudo lsof -nP -i :14001

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 14001 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 14001
netstat -ano | findstr :14001

From another machine

nmap -p 14001 -sV <host>
sudo nmap -sU -p 14001 <host>
nc -zv <host> 14001

Block it in the firewall

sudo ufw deny 14001/tcp                                         # Linux (ufw)

04 FAQ
What is port 14001 used for?

Port 14001 is assigned by IANA to sua (SUA).

Is port 14001 TCP or UDP?

Port 14001 is registered for TCP and UDP and SCTP.

Is it safe to open port 14001?

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 14001 is open?

On Linux run "ss -ltnup 'sport = :14001'", on macOS "lsof -nP -i :14001", and on Windows "netstat -ano | findstr :14001" to see the local process. From another machine, "nmap -p 14001 <host>" shows whether it is reachable.
