# WHATPORT(1035)

## NAME

port 1035 — mxxrlogin (MX-XR RPC) — Registered as "MX-XR RPC" to Valassis — a vendor-private RPC service with no public specification.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 1035 to `mxxrlogin`, described as "MX-XR RPC", registered in 2003 by Valassis and last modified in 2015. It is a proprietary remote-procedure-call service; no protocol document, client, or server is publicly available, so the registration is essentially all there is to know. As with its neighbours, an open 1035 on a scan is far more likely to be a dynamically assigned Windows RPC endpoint from the old 1025-5000 range than the registered service.

## EXPOSURE

**Expose with care.** A login-bearing RPC service with no public specification cannot be audited from outside — keep anything answering here on a private network until you know what it is.

## CHECK

```sh
nmap -Pn -sV -p 1035 TARGET
```
