| WinPcap Drivers (which are
basically ports of libpcap for Windows NT) are excellent tools using which you can both
read and write to the network on Windows NT. I've personally used Winpcap v 2.02 with
great success. Not only could you capture packets, but (using libnetnt) you can also craft
your own packets! What more can one ask for? However, the
latest release v 2.1 seems to be horribly broken! It is supposed to run on both Windows NT
and Windows 2000. However, it does neither. I had a Windows NT 2000 Professional box
running WinPcap v2.1 on a D-Link Adapter. All my captured packets were garbage! I also
cross-checked with their own Analyzer app! It just could not decode packets! (I observed
the same behavior on Windows NT also. BTW, both were fresh builds. So no DLL problems
here)
Moral of the story: Before porting your apps to Winpcap v2.1,
pls. test it thoroughly! |
