# WHATPORT(5859)

## NAME

port 5859 — wherehoo (WHEREHOO) — Registered to WHEREHOO, a location-service project from the early 2000s that no longer exists in the wild.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 5859 to wherehoo, "WHEREHOO", registered by Jim Youll for a location-oriented service of that name. The project is long defunct and there is no deployed base to speak of, so the registration is history rather than a description of what runs there. An open 5859 today is some other application that took an unclaimed-looking number.

## EXPOSURE

**Expose with care.** The registered service is dead, so anything listening is unidentified. Find the process rather than trusting the registry name.

## CHECK

```sh
sudo lsof -nP -iTCP:5859 -sTCP:LISTEN
```
