# WHATPORT(7749)

## NAME

port 7749 — Unassigned — Unassigned — it sits in the long empty 7748-7776 gap below the game-server crowd on 7777.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA's last registration before this gap is 7747 (prgp, Put/Run/Get Protocol); 7748 through 7776 are unassigned, 7749 among them. Nmap has no service name for it and scores it near 0.015% open frequency. Nothing standard claims it, so treat any listener as application-specific and identify it locally.

## EXPOSURE

**Expose with care.** Unregistered port, unknown service — resolve the owning process before making a firewall decision.

## CHECK

```sh
sudo lsof -nP -iTCP:7749 -sTCP:LISTEN
```
