Argus: GSI PEP Callout: Troubleshooting


By default the GSI PEP Callout module logs info and error via syslog.

The syslog facility used is local5 and the identifier is gsi_pep_callout. These log messages are typically in /var/log/messages

Enabling Debug Information

You can enable the debugging mode of the GSI PEP Callout module to troubleshoot your problem.

Environment Variables

You can set the following environment variables to enable debug mode:

  • GSI_PEP_CALLOUT_DEBUG_LEVEL Set the debug level from 0 (none) to 9 (lot of info). Default is 0.
  • GSI_PEP_CALLOUT_DEBUG_FILE Set the file to log the debugging information. Default is stderr.


This example shows how to start the GridFTP server in debug mode. The configuration files gsi-authz.conf and gsi-pep-callout.conf must be correctly configured as describe here.

# set the gsi-authz config to use (default /etc/grid-security/gsi-authz.conf)
export GSI_AUTHZ_CONF=/etc/grid-security/gsi-authz.conf
# set the gsi-pep-callout config to use (default /etc/grid-security/gsi-pep-callout.conf)
export GSI_PEP_CALLOUT_CONF=/etc/grid-security/gsi-pep-callout.conf

globus-gridftp-server -d 255 -p 9999 -debug

The GridFTP server is now running and listening on port 9999. Use the uberftp client or globus-url-copy to connect to the server with your Grid credentials and obtain debugging information from the server:

  • uberftp -P 9999 HOSTNAME
  • globus-url-copy file:///etc/passwd gsiftp://HOSTNAME:9999/tmp/e33
