Abstract
This provider connects to a GridFTP server, reads its banner, and puts the banner in the
Index Service. If the connection cannot be made in 30 seconds or some other error occurs, the
server is marked as down. This provider is an execution aggregator provider. These providers are
quite useful as is and additionally serve as an example of how to create others. The perl script
and configuration file can be modified to the user's liking once installed. This provider has a
perl script and an XML configuration file. The perl script is used to obtain information and
formated the information into xml output. The output is written to stdout where it is gathered
and put into the Index Service. The XML file is of a common format that is explained here. After
installing the package the xml configuration files will be copied to
$GLOBUS_LOCATION/etc/globus_wsrf_mds_index/default_providers/ where the
DefaultIndexService will find them and use them to register the provider.

This is an execution aggregator source based information provider.
The following configuration is required for this information provider:
In order to grant permission to the installed perl scripts the user must edit the file: $GLOBUS_LOCATION/etc/globus_wsrf_mds_index/jndi-config.xml such that the tags:
<parameter> <name>executableMappings</name> <value> aggr-test=aggregator-exec-test.sh, pingexec=example-ping-exec </value> </parameter>includes the new provider. For example:
<parameter> <name>executableMappings</name> <value> gridftp-info=gridftp-banner.pl </value> </parameter>This provider connects to a gridftp server, reads its banner, and puts the banner in the index. If the connection cannot be made in 30 seconds, or some other error occurs the server is marked as down. To change what server is to be monitored edit the file:
GLOBUS_LOCATION/etc/globus_wsrf_mds_index/default_providers/gridftp-info-reg.xml
and change the line:
<RegistrantEPR xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/03/addressing" xmlns:agg="http://mds.globus.org/aggregator/types"> <wsa:Address>ftp://www.SITE.COM:2811</wsa:Address> </RegistrantEPR>from "ftp://www.SITE.COM:2811" to the server of your choice.

General security considerations associated with the container and all MDS services apply. See: Aggregator Framework.
By default, the aggregator sources do not use authentication credentials -- they retrieve information using anonymous SSL authentication or no authentication at all, and thus retrieve only publicly-available information. If a user or administrator changes that configuration so that a service's aggregator source uses credentials to acquire non-privileged data, then that user or administrator must configure the service's aggregator sink to limit access to authorized users.
