# WHATPORT(8765)

## NAME

port 8765 — Ultraseek HTTP (registered) — Registered to a search appliance nobody runs any more, so a listener here today is almost always someone's own app.

Protocol: TCP  
IANA: ultraseek-http

## DESCRIPTION

IANA registers 8765 as ultraseek-http, the HTTP interface of the Ultraseek enterprise search server (Infoseek, later Verity and Autonomy). That product has been out of circulation for years, so the registration is history rather than a prediction. What you actually find on 8765 is usually an unrelated service that picked a memorable four-digit port. Identify the process before assuming anything about the protocol.

## EXPOSURE

**Expose with care.** The verdict depends entirely on what is really bound there; treat an unidentified HTTP-ish listener as unauthenticated until you have checked.

## CHECK

```sh
sudo lsof -nP -iTCP:8765 -sTCP:LISTEN
```
