Port 1419 is officially registered with IANA as "Timbuktu Service 3 Port."1 It belongs to the registered ports range (1024-49151), where vendors can claim specific port numbers for their applications.
But here's the thing: the application that owns this port doesn't exist anymore.
What Timbuktu Was
Timbuktu was remote control software before remote control was ubiquitous. First developed in the late 1980s by WOS DataSystems, it let you see and control another computer's screen across a network—a remarkable capability when most people were still using floppy disks to transfer files.2
The software used a suite of four consecutive ports for different functions:3
- Port 1417 - Control channel
- Port 1418 - Screen observation (remote viewing)
- Port 1419 - Send files (file transfer to remote system)
- Port 1420 - Exchange files (bidirectional file transfer)
Port 1419 specifically handled the "Send Files" service—one-way file transfers from your machine to the remote computer you were controlling.
The Journey Through Ownership
Timbuktu changed hands several times. WOS Data Systems was purchased by Farallon Computing in July 1988. Farallon became Netopia in 1999. Motorola acquired Netopia in 2007. Eventually the product line ended up with Arris.2
On April 28, 2015, Arris sent an email to customers: development of Timbuktu was ending. Sales would stop in 90 days.2
What This Port Means Now
Port 1419 is a ghost port. Officially registered, technically assigned, but serving software that no longer exists. It's a fossil in IANA's port registry—evidence of a product that mattered in its time but has been replaced by VNC, Remote Desktop Protocol, screen-sharing features built into operating systems.
You might occasionally see port 1419 listed in unofficial uses—some sources mention IBM WebSphere Application Server using it for RPC over HTTP4—but these are informal observations, not official assignments.
The Registered Ports Range
Port 1419 sits in the registered ports range (1024-49151). This range was created so vendors could claim port numbers for their applications without the strict requirements of well-known ports (0-1023). You register with IANA, you get your port, your application uses it.
The system works when applications are active. When they die, the port remains registered—a nameplate on a door to an empty room.
Checking What's Listening
If you want to see if anything is actually using port 1419 on your system:
Linux/macOS:
Windows:
Most likely, nothing will be there. Timbuktu hasn't been sold since 2015, and most installations have long since been replaced.
Why Ghost Ports Matter
The existence of ports like 1419 reveals something about how the Internet's infrastructure works. Port numbers are finite—only 65,535 exist. The registered range holds thousands of assignments to applications that are dead, dying, or barely used.
IANA doesn't routinely reclaim registered ports when software dies. The registry grows but rarely shrinks. Port 1419 will likely remain "Timbuktu Service 3 Port" indefinitely, even though Timbuktu Service 3 is gone.
This isn't a problem—we're not running out of ports. But it's honest. The Internet carries the weight of its history. Every protocol that ever mattered, every application that once solved a real problem, leaves traces. Port numbers are one kind of trace.
Port 1419 is a memorial to software that made remote control possible before it was easy.
