New tool release - "Egress Buster" - Find outbound ports

This write-up documents a simple penetration-testing toolset: `egressbuster` (runs on an internal/victim host to attempt outbound connections across a port range) and `egress_listener` (an Internet-facing listener that logs successful inbound connections). The author explains how to run the tools, shows sample listener output demonstrating which outbound ports were allowed, and notes practical limitations (OS issues when creating >1000 listeners and that the socket handlers are multithreaded for speed).
