Hi !

Where can I found a C/C++ source code (with device-drive or not) for
list all TCP/UDP ports and your own processes ?

I found a source code for list in Windows XP only… but dont work with
Windows NT/2000 (only list ports)…
http://www.sysinternals.com/files/netstatp.zip

Any help is welcome…

Thank you

Marcos

IP Helper API's is the ONLY documented way
to get this info and process relationship is available
only on XP. There are a few un documented and
unreliable solutions available on net, do a google for "PortUser"

Hi!

I had the same problem. Here’s how I solved it:

Enumerate all handles of type “file” of the particular process (do this in
Ring3). With the handle you get the kernel-object-address. Step into Ring0 and
get the related device-object of that file-object. Check if the
device-object is one of the TDI devices (\Device\Tcp, \Device\Udp). If yes, then query
(TDI_QUERY_INFORMATION) the device for the IP-address and port-number.

That’s it!

Hope that helps.

Hi !

Where can I found a C/C++ source code (with device-drive or not) for
list all TCP/UDP ports and your own processes ?

I found a source code for list in Windows XP only… but dont work with
Windows NT/2000 (only list ports)…

Any help is welcome…

Thank you
