# WHATPORT(5862)

## NAME

port 5862 — Unassigned — Unassigned at IANA, sitting one below the PlanetPress Suite Messenger registration on 5863.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 5863 to ppsuitemsg (PlanetPress Suite Messenger) but leaves 5862 empty, and no common product defaults to it. Adjacency is not evidence — a service on 5862 has no necessary relationship to its registered neighbour. As with the rest of the unassigned 58xx block, identify the listener directly.

## EXPOSURE

**Expose with care.** Unknown service on an unregistered port. Determine what it is before allowing traffic to it.

## CHECK

```sh
sudo lsof -nP -iTCP:5862 -sTCP:LISTEN
```
