Bouncer

Bouncer is a Linux-based application designed to manage system access and monitor incoming connection attempts. It functions by filtering network traffic based on user-defined rules, allowing administrators to restrict access to specific services or ports. The software logs connection requests, providing a record of activity that can be reviewed to identify patterns in traffic. It is intended for use in environments where granular control over network entry points is required.

The application integrates with system-level networking components to enforce its filtering policies. It provides a command-line interface for configuring access lists and viewing real-time logs of blocked or permitted attempts. By acting as an intermediary between external traffic and local services, Bouncer assists in maintaining the defined boundaries of a system's network exposure. It is limited to the Linux platform and requires administrative privileges to modify system firewall or network configurations.
