01 Security

Is port 2514 dangerous?

We have no specific security note for port 2514. Its risk depends on the program actually listening on it. General advice for network services services:

  • Answer only the networks that need the service (no open resolvers, relays or reflectors).
  • UDP services can be abused for DDoS amplification: rate-limit or block them at the edge.
  • Disable legacy test services that have no use in production.

03 Check it

Which program uses port 2514, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2514'      # process listening on 2514
sudo lsof -nP -i :2514

macOS

sudo lsof -nP -i :2514

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2514 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2514
netstat -ano | findstr :2514

From another machine

nmap -p 2514 -sV <host>
sudo nmap -sU -p 2514 <host>
nc -zv <host> 2514

Block it in the firewall

sudo ufw deny 2514/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2514" -Direction Inbound -LocalPort 2514 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2514 used for?

Port 2514 is assigned by IANA to facsys-ntp (Facsys NTP).

Is port 2514 TCP or UDP?

Port 2514 is registered for TCP and UDP.

Is it safe to open port 2514?

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. Answer only the networks that need the service (no open resolvers, relays or reflectors).

How do I check if port 2514 is open?

On Linux run "ss -ltnup 'sport = :2514'", on macOS "lsof -nP -i :2514", and on Windows "netstat -ano | findstr :2514" to see the local process. From another machine, "nmap -p 2514 <host>" shows whether it is reachable.
