# WHATPORT(1029)

## NAME

port 1029 — solid-mux (Solid Mux Server) — Registered in 2004 as "Solid Mux Server"; on a real scan it is usually a Windows RPC endpoint instead.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1029 to `solid-mux`, described as "Solid Mux Server", registered in November 2004 to an individual assignee. The protocol has no public specification and no open implementation, so the registration is effectively the whole record. What you actually see on 1029 is the same story as its neighbours: on Windows 2000/XP/Server 2003 it falls inside the old 1025-5000 dynamic RPC range and gets handed to whichever DCOM or RPC service starts early, which is why scanners commonly label it `msrpc`.

## EXPOSURE

**Expose with care.** No public protocol to reason about; if it turns out to be a Windows RPC endpoint, it should not be internet-facing at all.

## CHECK

```sh
nmap -Pn -sV -p 1029 TARGET
```
