globus-gatekeeper-admin
GLOBUS-GATEKEEPER-(8) University of Chicago GLOBUS-GATEKEEPER-(8)NAME
globus-gatekeeper-admin - Manage globus-gatekeeper services
SYNOPSIS
globus-gatekeeper-admin [-h]
globus-gatekeeper-admin [-l] [-n NAME]
globus-gatekeeper-admin [-e SERVICE] [-n NAME]
globus-gatekeeper-admin [-E]
globus-gatekeeper-admin [-d SERVICE]
DESCRIPTION
The globus-gatekeeper-admin program manages service entries which are used by the globus-gatekeeper to execute services. Service entries
are located in the /etc/grid-services directory. The globus-gatekeeper-admin can list, enable, or disable specific services, or set a
service as the default. The -h command-line option shows a brief usage message.
Listing services
The -l command-line option to globus-gatekeeper-admin will cause it to list all of the services which are available to be run by the
globus-gatekeeper. In the output, the service name will be followed by its status in brackets. Possible status strings are ENABLED,
DISABLED, and ALIAS to NAME, where NAME is another service name.
If the -n NAME is used, then only information about the service named NAME is printed.
Enabling services
The -e SERVICE command-line option to globus-gatekeeper-admin will cause it to enable a service so that it may be run by the
globus-gatekeeper.
If the -n NAME option is used as well, then the service will be enabled with the alias NAME.
Enabling a default service
The -E command-line option to globus-gatekeeper-admin will cause it to enable a service alias with the name jobmanager. The
globus-gatekeeper-admin program will choose the first service it finds as the default. To enable a particular service as the default, use
the -e parameter described above with the -n parameter.
Disabling services
The -d SERVICE command-line option to globus-gatekeeper-admin will cause it to disable a service so that it may not be run by the
globus-gatekeeper. All aliases to a disabled service are also disabled.
FILES
/etc/grid-services
Default location of enabled gatekeeper service descriptions.
