01 Security

Is port 14500 dangerous?

We have no specific security note for port 14500. 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 14500, and is it reachable?

Linux

sudo ss -ltnup 'sport = :14500'      # process listening on 14500
sudo lsof -nP -i :14500

macOS

sudo lsof -nP -i :14500

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 14500 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 14500
netstat -ano | findstr :14500

From another machine

nmap -p 14500 -sV <host>
nc -zv <host> 14500

Block it in the firewall

sudo ufw deny 14500/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 14500" -Direction Inbound -LocalPort 14500 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 14500 used for?

Port 14500 is assigned by IANA to xpra (xpra network protocol).

Is port 14500 TCP or UDP?

Port 14500 is registered for TCP.

Is it safe to open port 14500?

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 14500 is open?

On Linux run "ss -ltnup 'sport = :14500'", on macOS "lsof -nP -i :14500", and on Windows "netstat -ano | findstr :14500" to see the local process. From another machine, "nmap -p 14500 <host>" shows whether it is reachable.
