IP Port monitor
-
I am trying to write a client app that can monitor IP ports. Like which ports are taken and what are they being used for. I have done some work with WinSock and Win32 networking API, but can't find anything about this. I would prefer a means to set a message if on a single port or multiple ports that fire when the port becomes active, but will settle for a port listener that will check the ports and tell me what is going on with them. Has anyone tried this before? Thanks. Leo T. Smith Senior Programmer/Analyst Hartwick College

Try look at the open Source project WinDump (for Windows) or TcpDump (for unix). It sniffs all network trafic based on filters! But you have the source and can make your own filters..... http://www.tcpdump.org/ http://netgroup-serv.polito.it/windump/ Cheers, Frank

The OS is Actually any of the Win32 Platforms. I will use the Win32 API's to detect OS, and the whichever code is necessary (UniCode conversion also is not an issue). I would prefer API calls or direct TCP/IP functions over MFC Wrappers. Leo T. Smith Senior Programmer/Analyst Hartwick College

Hello Leo, There is a very good article by Ton Plooy in the February 1998 edition of the Windows Developers' Journal. The title is : "Scanning Internet Ports". A sample program with full source codes is also given. The following is the link to the article : http://www.wdj.com/articles/1998/9802/9802b/9802b.htm?topic=articles I believe the sample program will be perfect for you. Best of luck. Regards, Bio.
