This lite tool shows a list of the TCP and UDP ports in use.
Not only does it show the information but it also allows you to manage some options about the ports: detailed information, open or close connections, kill processes,...
Another interesting function is the possibility of creating a report in HTML with the current data.
The user can choose the data featured on each column. From the options menu you can enable and disable elements.
The information shown by CurrPorts can be: Remote IP, origin ports, destination ports, open type and much more.
