Fport介绍

fport supports Windows NT4, Windows 2000 and Windows XP

fport 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.

Usage:

C:\>fport
