# WHATPORT(82)

## NAME

port 82 — XFER Utility — Registered to the XFER Utility, a service nobody runs; in practice another spillover HTTP port.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers port 82 as 'xfer — XFER Utility', assigned to Thomas M. Smith, on TCP and UDP. There is no RFC, no specification anyone cites, and no implementation in general circulation. What actually turns up on 82 is the same thing that turns up on 81 and 83: an additional HTTP listener, an admin panel, or a proxy placed on the next free port after 80. Fingerprint it as HTTP first; the registered name tells you nothing useful.

## EXPOSURE

**Expose with care.** Whatever is here is unregistered in practice and usually cleartext HTTP; judge it by the service you actually find, not by the IANA name.

## CHECK

```sh
curl -sSI --max-time 5 http://TARGET:82/
```
