Port 20014: FileWave Booster — The Caching Layer That Scales Device Management

What This Port Does

Port 20014 operates in the registered ports range (1024-49151), the middle tier of the port system where vendors can register specific services with IANA. This port primarily serves FileWave Booster communications—the encrypted SSL channel for client-to-Booster and Booster-to-Booster traffic in FileWave's device management infrastructure.¹²

FileWave is enterprise device management software. Boosters are caching servers deployed across a network to distribute software packages, updates, and configurations to managed devices (computers, tablets, phones) without every request hammering the central server. Port 20014 carries the encrypted version of these communications.

The Architecture

Port 20014 doesn't exist in isolation. It's part of a port pair:

• Port 20013: The base port (now deprecated)
• Port 20014: The SSL/encrypted version (port 20013 + 1)

When you configure FileWave to use port 20013, it automatically sets up 20014 as the encrypted channel. Modern FileWave deployments prioritize 20014, using encryption by default.¹

How It Works

Client to Booster: When a managed device needs a software package, it connects to the nearest Booster on port 20014 instead of reaching back to the main FileWave server. The Booster either has the package cached or fetches it once and serves it to all requesting clients.

Booster to Booster: Boosters communicate with each other on ports 20014 and 20018, synchronizing their caches and coordinating distribution across the network.¹

This architecture solves a genuine problem: if you're managing 10,000 devices and push a software update, you don't want 10,000 connections flooding your main server. The Boosters absorb that load, each serving hundreds or thousands of local clients.

The DART Reporting Confusion

Some port databases list 20014 as "DART Reporting server."³ This appears to be an unofficial designation that doesn't reflect the port's primary real-world use in FileWave deployments. It's marked as unofficial and unencrypted in those databases—ironic, given that 20014's actual purpose in FileWave is specifically to provide encryption.

This is common in the registered port range: ports get listed under one name in databases while being actively used for something completely different in production environments.

Security Considerations

Port 20014 carries encrypted traffic (SSL/TLS) in FileWave deployments. This is important because the traffic includes:

• Software packages and installers
• Configuration files
• Device inventory data
• Management commands

Firewall rules: If you're running FileWave with external devices, you need to open port 20014 for incoming connections to your Boosters.⁴ Make sure you're actually getting encrypted connections—verify the SSL configuration rather than assuming it's working.

Network segmentation: Boosters often sit at the edge of network segments (remote offices, DMZs). Ensure port 20014 is only accessible from legitimate managed devices and other Boosters, not the entire Internet.

How to Check What's Using This Port

On Linux/macOS:

sudo lsof -i :20014
sudo netstat -tulpn | grep 20014

On Windows:

netstat -ano | findstr :20014

If you see something listening on 20014 and you're not running FileWave, investigate. It could be:

• Another application using this registered port
• The mysterious DART Reporting server
• Something you should be suspicious of

Why Unassigned/Registered Ports Matter

Port 20014 illustrates how the registered port range works in practice:

Registration doesn't mean universal adoption: FileWave registered these ports for their use, but there's no guarantee another vendor won't use the same port for something else. The DART Reporting designation suggests exactly that happened.

Unofficial use is common: In the registered range (1024-49151), ports can be registered with IANA, but enforcement is impossible. Your application can listen on any port in this range. Registration is more like a courtesy—"hey, we're using this"—than a hard claim.

Context determines meaning: Port 20014 means FileWave Booster in an enterprise environment with device management. It means DART Reporting server in some other context. It means nothing in particular on your laptop unless you're running one of those services.

The registered port range is the Internet's middle ground—not the well-known ports that everyone agrees on (0-1023), not the free-for-all of ephemeral ports (49152-65535), but the negotiated space where vendors stake claims that may or may not be honored by everyone else.
