The SSL variant of the IONA Orbix 2000 CORBA locator daemon.
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.
Expose with care
It is middleware plumbing, not a public service; keep it on the application network even though this variant is TLS-wrapped.
