01 Security

Is port 14000 dangerous?

We have no specific security note for port 14000. 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 14000, and is it reachable?

Linux

sudo ss -ltnup 'sport = :14000'      # process listening on 14000
sudo lsof -nP -i :14000

macOS

sudo lsof -nP -i :14000

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 14000 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 14000
netstat -ano | findstr :14000

From another machine

nmap -p 14000 -sV <host>
sudo nmap -sU -p 14000 <host>
nc -zv <host> 14000

Block it in the firewall

sudo ufw deny 14000/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 14000" -Direction Inbound -LocalPort 14000 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 14000 used for?

Port 14000 is assigned by IANA to scotty-ft (SCOTTY High-Speed Filetransfer).

Is port 14000 TCP or UDP?

Port 14000 is registered for TCP and UDP.

Is it safe to open port 14000?

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 14000 is open?

On Linux run "ss -ltnup 'sport = :14000'", on macOS "lsof -nP -i :14000", and on Windows "netstat -ano | findstr :14000" to see the local process. From another machine, "nmap -p 14000 <host>" shows whether it is reachable.
