Is port 14250 dangerous?

We have no specific security note for port 14250. 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 14250, and is it reachable?

Linux

sudo ss -ltnup 'sport = :14250'      # process listening on 14250
sudo lsof -nP -i :14250

macOS

sudo lsof -nP -i :14250

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 14250 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 14250
netstat -ano | findstr :14250

From another machine

nmap -p 14250 -sV <host>
sudo nmap -sU -p 14250 <host>
nc -zv <host> 14250

Block it in the firewall

sudo ufw deny 14250/tcp                                         # Linux (ufw)

04 FAQ
What is port 14250 used for?

Port 14250 is assigned by IANA to cps (Fencing Server).

Is port 14250 TCP or UDP?

Port 14250 is registered for TCP and UDP.

Is it safe to open port 14250?

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 14250 is open?

On Linux run "ss -ltnup 'sport = :14250'", on macOS "lsof -nP -i :14250", and on Windows "netstat -ano | findstr :14250" to see the local process. From another machine, "nmap -p 14250 <host>" shows whether it is reachable.
