Port 1114: Mini SQL — The first free database

Port 1114 carries mSQL (Mini SQL), the database that made the dynamic web possible.

What Runs on Port 1114

Port 1114 is registered for mSQL (Mini SQL) on both TCP and UDP. This was the first lightweight, affordable SQL database management system—created at a time when database software cost thousands of dollars and required expensive hardware.¹

The Story

In 1993, David Hughes was building a network monitoring system called Minerva. He needed a database. The problem: no free SQL database existed. Enterprise databases were expensive and too heavy for the modest hardware he was using.

Hughes tried adapting Postgres, but it was too slow. So he built his own—a minimal implementation of SQL that could run on low-specification systems. He called it Mini SQL, or mSQL.²

Released in 1994, mSQL became the first freely available SQL implementation for Linux and Unix systems. It wasn't feature-complete. It didn't implement the entire SQL standard. But it was fast, lightweight, and cheap enough for developers to actually use.³

Why This Port Mattered

Before mSQL, database-driven websites were rare. Databases were enterprise tools. mSQL changed that. By the mid-1990s, it had become a key technology in the rise of dynamic web applications—letting developers store and retrieve data without expensive licensing.⁴

Companies like HP, Cisco, Tandem, Cray, and General Electric incorporated mSQL into their products. By the late 1990s, it had a large and widespread install base.

Then MySQL arrived. Inspired by mSQL, MySQL was created in 1995 to be faster and more flexible. By 1996, mSQL development began to stagnate. By 1999, MySQL had surpassed it in popularity.⁵

Today, mSQL is still maintained by Hughes Technologies, primarily for internal use and existing licensees. But its legacy is everywhere: it proved that SQL databases could be lightweight, accessible, and affordable. It taught the web how to talk to databases.

How It Works

mSQL implements a subset of the SQL standard optimized for performance on minimal hardware. The protocol on port 1114 handles client-server communication—queries go in, results come back.

The design philosophy: do less, do it fast. mSQL sacrificed features for speed and simplicity, making it viable on systems that couldn't run traditional databases.

Security Considerations

mSQL is rarely seen in modern production environments. If you find port 1114 open on a system, it's likely either:

• A legacy installation still running mSQL
• An unofficial use of the port by another service
• A historical system preserved for compatibility

Check what's actually listening:

# On Linux/Mac
sudo lsof -i :1114

# On Windows
netstat -ano | findstr :1114

The Ghost in the Port

Port 1114 carries a ghost of the early web. For a few crucial years in the mid-1990s, this was where the Internet learned that databases didn't have to be expensive, slow, or complicated. Every dynamic website, every database-driven application you use today—they all trace back to the moment David Hughes decided to build his own SQL implementation because nothing else existed.

MySQL gets the credit. PostgreSQL gets the respect. But mSQL got there first.
