01 Security

Is port 20014 dangerous?

We have no specific security note for port 20014. 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 20014, and is it reachable?

Linux

sudo ss -ltnup 'sport = :20014'      # process listening on 20014
sudo lsof -nP -i :20014

macOS

sudo lsof -nP -i :20014

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 20014 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 20014
netstat -ano | findstr :20014

From another machine

nmap -p 20014 -sV <host>
sudo nmap -sU -p 20014 <host>
nc -zv <host> 20014

Block it in the firewall

sudo ufw deny 20014/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 20014" -Direction Inbound -LocalPort 20014 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 20014 used for?

Port 20014 is assigned by IANA to opendeploy (OpenDeploy Listener).

Is port 20014 TCP or UDP?

Port 20014 is registered for TCP and UDP.

Is it safe to open port 20014?

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 20014 is open?

On Linux run "ss -ltnup 'sport = :20014'", on macOS "lsof -nP -i :20014", and on Windows "netstat -ano | findstr :20014" to see the local process. From another machine, "nmap -p 20014 <host>" shows whether it is reachable.
