Port 2770: Veronica — A Ghost from Gopherspace

What This Port Is

Port 2770 is formally assigned by IANA to Veronica, a search engine built for the Gopher protocol. It operates over both TCP and UDP.

Gopher is not the web. It predates the web — a text-based, menu-driven system for navigating distributed information, developed at the University of Minnesota in 1991. Gopher had no URLs, no HTML, no hyperlinks in the modern sense. You navigated menus. Documents lived on Gopher servers. It was genuinely useful, and for a brief window, it was how a lot of people accessed information on the Internet.

Veronica was Gopher's search engine.

What Veronica Was

Steven Foster and Fred Barrie at the University of Nevada, Reno released Veronica in November 1992. The name is a backronym: Very Easy Rodent-Oriented Net-wide Index to Computer Archives. (It's also a nod to Archie Comics — the Archie search engine, which indexed FTP archives, came first.)

Veronica worked the way modern search engines work: a crawler visited Gopher servers continuously, indexing the titles of every menu item it found. Users could then search those titles with keywords. By early 1994, Veronica was processing over a million searches per month across an index of roughly 15 million items from around 5,000 Gopher servers.¹

That was the peak. Netscape shipped later that year. The web had images. Gopher didn't. The rest is history.

The Port Assignment

Port 2770 carries a registration to Jonas Oberg in the IANA registry — a contact associated with Veronica's later development. The assignment covers both TCP and UDP.

The protocol behind it is not formally documented in a publicly available RFC the way HTTP or SMTP are. Veronica queries traveled over TCP, piggybacking on Gopher's basic request-response model: send a search string, receive a Gopher menu of matching items. Simple, functional, gone.

What's on This Port Today

Almost certainly nothing. Gopher servers still exist in small numbers — a community of hobbyists maintains "Gopherspace" — but Veronica's original infrastructure is long defunct, and port 2770 sees essentially no traffic in any standard network analysis.

If you see activity on port 2770 on your systems, it is not Veronica. Check what's actually running.

How to Check What's Listening

On Linux/macOS:

# Show what process is listening on port 2770
ss -tlnp | grep 2770
# or
lsof -i :2770

On Windows:

netstat -ano | findstr :2770

If something shows up, look up the process ID to find out what it actually is.

Why Unassigned (or Nominally Assigned) Ports Matter

The registered port range runs from 1024 to 49151. IANA tracks assignments here, but registration doesn't mean a service is active — it means someone once claimed the number. Veronica is a clean example: formally assigned, practically dormant for thirty years.

This matters for security. An unexpected service listening on a registered port is worth investigating. Malware and unauthorized services often bind to obscure registered ports precisely because administrators assume something "official" must be there. Port 2770 lighting up on your network is not Veronica come back from the dead. It's something else.

A Note on Gopherspace

If you're curious what Gopher actually felt like, it still runs. A small community maintains active Gopher servers accessible today. Veronica's spirit lives on in a replacement called Veronica-2, reachable through any Gopher client. Port 70, not 2770 — but the same idea, thirty years later.²
