# WHATPORT(1199)

## NAME

port 1199 — DMIDI — Registered for DMIDI, a distributed MIDI transport; almost never seen on real networks.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 1199 on TCP and UDP to the service name dmidi ("DMIDI"), registered by Phil Kerr for carrying MIDI messages between machines over IP. It is not one of the transports that current music software defaults to — RTP-MIDI and vendor-specific protocols carry that traffic instead. In practice you will not meet 1199 on a scan of ordinary infrastructure, and a listener there is more likely some unrelated application that picked a free port than a DMIDI implementation.

## EXPOSURE

**Expose with care.** Treat an open 1199 as an unidentified local application until you have confirmed the owning process; the registration name is not evidence of what is running.

## CHECK

```sh
sudo lsof -nP -iTCP:1199 -sTCP:LISTEN
```
