From the Doc: 'Fport is a very practical command line utility, which finds out which server program is responsible for opening a system's ports. It runs on the command line. Reports all open TCP/IP and UDP ports and maps them to the owning application. This is the same information you would see using the 'netstat -an' command, but it also maps those ports to running processes with the PID, process name and path. Fport can be used to quickly identify unknown open ports and their associated applications.'
