What Port 214 Is
Port 214 sits in the well-known ports range (0-1023), the reserved space where IANA assigns ports to system services and established protocols. These are the ports that require elevated privileges to bind to on Unix systems, the ports that carry the Internet's essential infrastructure.
Port 214 is officially assigned to vmpwscs — which stands for "VM PWSCS."1 Both TCP and UDP. Registered by someone named Dan Shia. And that's where the paper trail ends.
The Service That Wasn't There
Nobody knows what VM PWSCS actually does. The name suggests something related to virtual machines — maybe "VM Password Control System" or "VM Password Change Service" — but there's no RFC, no documentation, no open-source implementation, no commercial product that anyone remembers using port 214.
It's just a name in the IANA registry. A reservation made decades ago for a service that either never launched, or launched so quietly that it left no mark on the Internet's collective memory.
The Trojan That Was
What we do know is that port 214 has been flagged by security databases as having been used by trojans or viruses in the past.23 The specific malware names aren't well-documented anymore — these were likely old threats from the era when trojans would systematically scan through port ranges looking for anything open.
This is the pattern: a port gets assigned to a legitimate service. The service never takes off. The port sits empty. And eventually, something malicious notices the vacancy and moves in.
What This Port Represents
Port 214 is a reminder that the port registry is not a map of what actually runs on the Internet. It's a historical document, full of abandoned plans and forgotten projects. Out of 1,024 well-known ports, hundreds have assignments like this — official, documented, and completely unused in practice.
The well-known range was supposed to be for essential services. But in reality, it's also a graveyard of ideas that didn't ship, protocols that lost adoption battles, and services that solved problems nobody ended up having.
How to Check What's Listening
If you want to see if anything is actually using port 214 on your system:
Linux/Mac:
Windows:
Most likely, you'll see nothing. Port 214 is probably empty on your machine, as it is on most machines across the Internet.
Why Unassigned (or Forgotten) Ports Matter
The existence of ports like 214 matters because they represent the gap between official registry and actual practice. The IANA port registry is exhaustive and carefully maintained, but it doesn't reflect what services people actually run.
When you're configuring a firewall, you need to know which ports carry real traffic and which are just names in a database. When you're investigating suspicious network activity, you need to know that a connection to port 214 is unusual — not because the official assignment is malicious, but because almost nothing legitimate uses it anymore (if it ever did).
The well-known ports range is supposed to be the foundation. But even foundations have cracks, empty spaces, and forgotten corners. Port 214 is one of them.
