PortListener XP is a port listener for Windows XP. The tool installs and then listens on particular ports. This tool listens on multiple ports in one instance, drops to the systray, and also logs to files. It does not log in real time, but it does accrue connection totals (aggregated for all ports) on the main window. There are options to change colors and show alerts for various warning levels, but they seemed useless to me. Also, you can set a banner or connection reply to be sent back to connecting sessions, but that didn’t appear to work for me either…however, I do like the systray and multiple port options.
