cPFence offers a powerful, browser-based WebUI for managing all monitoring and security settings across your Enhance cluster. The WebUI is fully mobile-friendly, so you can manage monitoring and resource thresholds from any device—including your phone or tablet.
Our DDos protection module instantly blocks any IP with more than 100 concurrent connections (CONNECTIONS_LIMIT) to the server. It is designed to block aggressive IPs that repeatedly attempt attacks. Initially, the block is temporary, but if the same IP triggers multiple attacks, it results in a permanent block, and our IPDB is updated accordingly so all servers get the latest protection. You can adjust the limit in the configuration file located at /opt/cpfence/config.conf. The default value of 100 is recommended for optimal performance.
You can adjust all monitoring / DDos settings and notification thresholds for a specific server or all servers using the WebUI, or edit the configuration file manually if you prefer the CLI.
How to Adjust Owl Monitoring and Thresholds in the WebUI
- Open the cPFence WebUI on your Main Control Panel server.
- Go to System Settings from the sidebar menu.
- Use the Switch Server dropdown (bottom left) to select the server you want to adjust or choose All Servers for cluster-wide settings.
- Click Adjust Settings (One Server) or Adjust Settings (All Servers) as needed.
- Click Load Current Settings, make your changes (such as setting CONNECTIONS_LIMIT for DDos protection or enabling/disabling Owl monitoring or setting thresholds for CPU, memory, disk, etc.), and click Save & Restart to apply.
