# WHATPORT(8019)

## NAME

port 8019 — QuickBooks Database (qbdb) — Registered to Intuit as the QuickBooks database dynamic port.

Protocol: TCP  
IANA: qbdb

## DESCRIPTION

IANA lists 8019 as qbdb, "QB DB Dynamic Port", part of the block Intuit registered for QuickBooks Desktop. In a multi-user QuickBooks installation the Database Server Manager on the file-hosting PC uses this port so workstations can open the company file. Outside a Windows LAN running QuickBooks it is a rare port with no other well-known occupant.

## EXPOSURE

**Do not expose.** It is a file-hosted accounting database service designed for a trusted local network. Nothing about it is built to survive the open internet.

## CHECK

```sh
nmap -sV -Pn -p 8019 TARGET
```
