Port 3314: Unify Object Host — Registered, Forgotten

What Port 3314 Is

Port 3314 sits in the registered port range (1024–49151). These ports are documented by IANA, the organization that manages port assignments, to prevent collisions between applications competing for the same number.

IANA lists port 3314 as assigned to "Unify Object Host" (service name: uohost), registered in July 2012 by Daegis Inc. ¹

The Company Behind It

Daegis Inc. began as Unify Corporation, a software company that built application development tools and databases in the 1990s. In 2010, Unify merged with an eDiscovery firm and renamed itself Daegis. In 2015, OpenText acquired Daegis. ²

The "Unify Object Host" was likely a component of Unify's application server infrastructure — a host process for distributed objects in their development platform. No public documentation of the protocol survives in any meaningful form. The software that used this port is effectively gone.

The IANA entry remains. It will remain.

What This Means in Practice

If you see traffic on port 3314 today, it is not "Unify Object Host." That software isn't running anywhere you're likely to find it.

What you might find:

• Custom applications that picked 3314 arbitrarily or because it appeared "free"
• Malware that scans for or uses unmonitored registered ports as a communication channel
• Nothing — the most common answer

The Ghost Problem

IANA registered port space has thousands of entries like this one: software that was registered, used briefly or never, and then abandoned when the company dissolved, pivoted, or was acquired. But registered ports are permanent. IANA does not reclaim them.

This creates a landscape where roughly 40% of registered ports are assigned to software that hasn't been meaningfully deployed in years. Port 3314 is one of them.

The practical consequence: you can't assume a registered port is active or meaningful just because it has a name in the IANA database.

How to Check What's Listening on Port 3314

If you want to know what's actually using port 3314 on a machine you control:

On Linux or macOS:

ss -tlnp | grep 3314
# or
lsof -i :3314

On Windows:

netstat -ano | findstr :3314

If something appears, check the process ID against your running processes. If nothing appears, the port is idle — which is the expected result for port 3314 on any modern system.
