Port 2802: Veritas TCP1 — A Named Port Nobody Talks About

What Port 2802 Is

Port 2802 sits in the registered ports range (1024–49151). These are ports that applications and vendors can formally claim with IANA, the organization that maintains the global port number registry.

According to IANA, port 2802 is assigned to:

• TCP: Veritas TCP1
• UDP: Veritas UDP1

The registrant is Veritas — the enterprise software company best known for NetBackup, one of the most widely deployed backup and recovery platforms in large corporate and data center environments. ¹

What "Veritas TCP1" Actually Means

Honest answer: not much on its own.

Veritas registered a block of ports with generic placeholder names — "TCP1," "TCP2," and so on. This is a common pattern in IANA registration: a vendor stakes out port numbers for future use, gives them provisional names, and the ports may or may not see significant deployment. There is no publicly documented protocol specification for what "Veritas TCP1" is meant to carry.

NetBackup itself uses a well-known set of ports for its primary operations — notably port 1556 (Veritas PBX, the private branch exchange for internal process communication) and port 13724 (VNETD, the NetBackup legacy networking daemon). Port 2802 does not appear prominently in NetBackup's official firewall documentation. ²

The name is a name. The port is a reservation. The activity, if any, is undocumented publicly.

Other Observed Uses

Port 2802 has also been associated with SpellForce 2, a real-time strategy game, which uses ports 2802–2803 for multiplayer connectivity. This is a classic example of a game picking a registered-but-quiet port for its own networking needs — not officially assigned, just practically available. ³

Why Registered Ports Sometimes Stay Quiet

The registered range exists so vendors and developers can formally claim port numbers — preventing the chaos of two major applications accidentally colliding on the same port. But IANA registration doesn't require the port to be widely used or even deployed at all. Many registered ports are:

• Reserved for internal enterprise software that never ships publicly
• Claimed for a product version that was discontinued
• Held as precautionary assignments around active ports
• Simply registered and forgotten

Port 2802 appears to be in this category: formally assigned, rarely seen in the wild, carrying a name that raises more questions than it answers.

How to Check What's Using Port 2802 on Your System

If you see port 2802 active on a machine you manage, identify the process:

Linux / macOS:

sudo ss -tlnp | grep 2802
sudo lsof -i :2802

Windows:

netstat -ano | findstr :2802
# Then look up the PID:
tasklist | findstr <PID>

If it's a Veritas product, you likely have NetBackup or related Veritas software installed. If it's something else entirely — that's normal. Quiet registered ports get borrowed by applications all the time.
