BitNinja Linux Agent: Modernized PID Paths and Improved Service Reliability

This BitNinja Linux Agent release updates PID file handling across several modules, improves service startup coordination, and addresses an issue that could lead to high CPU load in CaptchaHttp. It is available through the beta and frequent update channels.

Modernized PID File Handling

BitNinja now migrates PID file references from the deprecated /var/run directory to the modern /run directory. This aligns PID file locations with current Linux FHS and systemd practices, where /run is typically provided as a tmpfs.

The update also relocates the BitNinja MQ and Process Analysis PID files to /run , while Reliable Auto Update receives consistent PID file handling. Dispatcher, WAF3, and related services also receive updated daemon PID path configuration.

Service Startup and Rule Application

PortHoneypot now waits until all critical dependencies are available before starting. This prevents premature startup and helps ensure consistent rule application.

CaptchaHttp CPU Load

CaptchaHttp includes a fix for an issue that could lead to high CPU load.

WAF Pro Optimization

WAF Pro now supports a static file exclude regex for optimization. This allows static files to be handled according to the configured exclusion pattern.

Service and Log Directory Configuration

The release updates log directory permissions for several BitNinja services and standardizes them where specified. Dispatcher, Process Analysis, Reliable Auto Update, and WAF3 receive log directory permission updates, including consistent 0750 permissions where applicable. WAF3 also receives configured service PID file and log permission settings.
