  • Last updated on

Verbose output is essential for proper analysis. You can enable logging for the client service to receive detailed information. Information for analysis, serialized by the Barracuda Network Access Client, is stored on the local hard drive if verbosity is enabled. These files can be found in the log directory located in the Barracuda Network Access Client installation directory.

  • connect.xml – Information about connectivity and connection errors.

  • downloadLocal.xml – Contains data received if a local-computer-based health evaluation succeeded.

  • downloadUser.xml – Contains data received if a user-based health evaluation succeeded.

  • health.xml – Last health evaluation result returned by the Access Control Server.

  • healthLocal.xml – Last health evaluation result for local-computer-based health evaluation.

    • /usr/local/bin/barracudavpn
