# WHATPORT(6788)

## NAME

port 6788 — SMC-HTTP — Registered in 2002 by Sun as smc-http — the cleartext sibling of the management console on 6789.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 6788/tcp and 6788/udp as smc-http, registered in November 2002 by a Sun Microsystems engineer. It is the HTTP half of the pair whose HTTPS half sits on 6789, the port Oracle's Solaris administration console still uses. There is no public protocol document for the registration itself, so on a modern network an open 6788 is either legacy Sun-derived management tooling or unrelated software using a free port.

## EXPOSURE

**Do not expose.** A management console reached over plain HTTP hands its session and credentials to anyone on the path. If the tooling still exists, use its TLS listener and firewall this one off.

## CHECK

```sh
curl -sI http://TARGET:6788/
```
