rootd / XRootD

Remote access to ROOT data files — the rootd daemon, and today XRootD, the storage backbone of LHC computing.

TCP IANA registry

Description

IANA assigned 1094 to rootd, the ROOT file server daemon, for Fons Rademakers of the CERN ROOT project. rootd itself is long superseded by XRootD, which keeps 1094 as its default listening port and serves data across worldwide grid infrastructure such as the WLCG. Seeing it open means a scientific data server: a storage element, a redirector fronting a federation of them, or an analysis facility's cache.

Exposed to the internet?

Expose with care

Grid XRootD endpoints are intentionally reachable by remote sites, but only with an authentication plugin (GSI/X.509, tokens) configured and read scopes controlled. An XRootD server exporting paths with unauthenticated access is a data leak.
