Port 3472: jaugsremotec-1 — A Ghost in the Registry

What Port 3472 Is

Port 3472 sits in the registered ports range (1024–49151) — the middle tier of the port numbering system, between the well-known ports used by HTTP, SSH, and DNS, and the ephemeral ports your operating system assigns on the fly to outgoing connections.

The registered range is where applications and services claim a permanent home. You apply to IANA, describe what your software does, and if approved, the port number becomes yours in the registry. Forever — even if your software disappears.

Port 3472 was registered as jaugsremotec-1, for a service called JAUGS N-G Remotec 1. Port 3473 holds its companion, jaugsremotec-2. Together they suggest a client-server or dual-channel remote control system, where "N-G" likely meant "next generation."

Who JAUGS was, what Remotec actually did, and whether it ever shipped — no documentation survives online. The registration is the only evidence that it existed at all.

What the Registered Range Means

The registered range has about 48,000 port numbers. A few thousand of them are actively used by software millions of people depend on. The rest are a mix of legitimate applications with small user bases, abandoned registrations from companies that dissolved, and placeholder names that never became real products.

Port 3472 appears to be in that second category. You are unlikely to find this port in use for its registered purpose on any modern system.

Checking What's Using This Port

If you see port 3472 open on a system you're investigating, the registered name explains nothing useful. Check what process actually opened it.

On Linux or macOS:

# Show the process using port 3472
sudo lsof -i :3472

# Or with ss (Linux)
sudo ss -tlnp | grep 3472

On Windows:

# Show process ID using port 3472
netstat -ano | findstr :3472

# Then look up the process
tasklist /FI "PID eq <pid>"

On any system with nmap:

nmap -sV -p 3472 localhost

Whatever you find won't be JAUGS. It will be something else — a development server, a gaming application, or software that chose this number because it was available and not famous enough to cause conflicts.

Why Ghost Ports Matter

The registered range is full of ports like 3472. They matter for a few reasons.

Security scanning context: When a scanner reports an open port, you need to know whether what's running matches what the registry says. Port 3472 has no known official software in active use, so anything you find there warrants a closer look.

Port selection: Developers choosing port numbers for new applications often scan for "uncontested" registered ports — ones with no known active users. Ghost registrations like jaugsremotec-1 are often quietly reused in practice.

The registry's limits: IANA maintains the registry, but it doesn't enforce it. A registration doesn't guarantee active use, and active use doesn't require a registration. The gap between what the registry says and what the Internet actually does is wide, and port 3472 is a small example of that gap.
