# WHATPORT(2119)

## NAME

port 2119 — Globus GRAM gatekeeper — The Globus gatekeeper — GSI-authenticated job submission on grid computing clusters.

Protocol: TCP  
IANA registry

## DESCRIPTION

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.

## EXPOSURE

**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.

## CHECK

```sh
nc -vz TARGET 2119
```
