Port Listener is a free, lightweight utility designed to enhance network troubleshooting by listening on specified TCP ports. It is ideal for developers, sysadmins, and security analysts who need to monitor network connections and analyze incoming data. The latest version, 2.00, introduces exciting new features including real-time visibility of TCP/IP connections, allowing users to see remote hosts connecting in real time.
One of the standout features is the built-in HTTP response capability, which enables the tool to respond to incoming HTTP requests with an HTML reply—an excellent way to confirm remote reachability. Additionally, Port Listener offers real-time data display, letting users monitor incoming traffic as it happens. It supports multiple instances, allowing users to track several ports simultaneously while running in System Tray mode to keep the workspace organized. Whether you’re troubleshooting connectivity issues, testing application communication, or conducting security analysis, Port Listener is an invaluable tool for enhancing your networking toolkit.
