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
FPort v2.0 - TCP/IP Process to Port Mapper

Pid Process Port Proto Path
392 svchost -> 135 TCP C:WINNTsystem32svchost.exe
8 System -> 139 TCP
8 System -> 445 TCP
508 MSTask -> 1025 TCP C:WINNTsystem32MSTask.exe
392 svchost -> 135 UDP C:WINNTsystem32svchost.exe
8 System -> 137 UDP
8 System -> 138 UDP
8 System -> 445 UDP
224 lsass -> 500 UDP C:WINNTsystem32lsass.exe
212 services -> 1026 UDP C:WINNTsystem32services.exe

The program contains five (5) switches. The switches may be utilized using either a '/'
or a '-' preceding the switch. The switches are;

Usage:
/? usage help
/p sort by port
/a sort by application
/i sort by pid
/ap sort by application path

Jeff is correct. Right click on the fport.exe, then choose Properties, then select the compatability tab, and finally check: compatability mode :: windowsxp

most of the problems you people are having seems like you are not using a command prompt:

Go to startrun type cmd
now run fport from the directory it is installed in.

I like to put it in windirsystem32

good luck
