# WHATPORT(16001)

## NAME

port 16001 — FileMaker Server admin connector (fmsascon) — FileMaker Server's local-only Admin Console URL: http://localhost:16001/admin-console.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 16001 as fmsascon, "Administration Server Connector", to FileMaker. Claris documents it as the way to open the Admin Console on the primary machine itself — http://localhost:16001/admin-console — and states plainly that port 16001 is only available on the local host, not from a remote machine. Remote administrators use the HTTPS console on the server's normal web port instead.

## EXPOSURE

**Do not expose.** Documented as loopback-only. If 16001 answers from another host, either the binding was changed or something other than FileMaker Server is listening.

## CHECK

```sh
curl -sI --max-time 5 http://localhost:16001/admin-console
```
