The Globus gatekeeper — GSI-authenticated job submission on grid computing clusters.
globus-gatekeeper is the front door of Globus GRAM: it authenticates an incoming TCP connection with GSI (X.509 proxy certificates over GSSAPI), maps the client's distinguished name to a local Unix account through the grid-mapfile, and then starts the requested service, normally a job manager that submits work to the site's batch scheduler. Running as root it defaults to port 2119. You find it on academic and national-lab compute clusters, alongside the GRIS information service on 2135. The Globus Toolkit itself is retired; surviving deployments run the community-maintained Grid Community Toolkit.
Expose with care
It is designed to be reachable between grid sites, but it runs jobs as local users on the strength of your CA trust and grid-mapfile. Only expose it with those maintained and the software patched — an abandoned gatekeeper is remote job execution on unsupported code.
