# WHATPORT(3077)

## NAME

port 3077 — Orbix 2000 Locator SSL — The SSL variant of the IONA Orbix 2000 CORBA locator daemon.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 3077 as `orbix-loc-ssl`, Orbix 2000 Locator SSL, the TLS-protected counterpart to the plaintext locator on 3075 (with configuration on 3076 and its SSL variant on 3078). Orbix is IONA's CORBA ORB, later a Micro Focus product, and the locator daemon is what CORBA clients ask to resolve object references to a running server. You meet it only inside long-lived enterprise middleware estates — telco, banking, insurance — and essentially nowhere else. An open 3077 says a CORBA infrastructure is still running here.

## EXPOSURE

**Expose with care.** It is middleware plumbing, not a public service; keep it on the application network even though this variant is TLS-wrapped.

## CHECK

```sh
openssl s_client -connect TARGET:3077 -brief </dev/null
```
