Dependencies

To ensure ConfigServer Firewall & Security (CSF) functions correctly, all required dependencies must be installed. Some dependencies are essential for the core operation of CSF, while others are only necessary if you plan to use specific optional features.


Optional Features

  • To enable Statistics ST_ENABLE = "1", you must install:
    • GB Graphics Library
    • GD::Graph Perl Module
