hi all,

I am trying to use winpcap to capture, send packets.

I found code from code project which uses dotnetWinpCap.dll for this
purpose. but it is not recognizing any packets, when ReceivePacket
method is called. can any one please tell me why it doesn't recognize.

is there any other way to capture, send packets and create log for the
received packets.

Thank you for your help in advance.

This just on DIGG.com

" As a lot of you may already know, there have been some issues with
WinPcap and version skew, as in different versions of the driver being
required for different pieces of software to work with it. This being
the case, I reccomend you to install the version of WinPcap that comes
with Ethereal even if you already have a version of this driver
installed. This will help to prevent any possible issues in the
future."

That will be the stuff dated 2003
www.codeproject.com/dotnet/dotnetwinpcap.asp
or maybe even the same 0project dated 2004 from
http://www.tutorialmaniacs.com/packe...t-library.html
by the same author that links to the 1st

The message board has some posts, although it look like a dead project.

No, as you must by doing what you are attempting realise it's not
exactly a trivial exercise or answer. The lack of detail you provided is
not helpful either.

You would have started at
http://www.winpcap.org/
then you would have downloaded some of the open source code and looked
at how it works.

Not forgetting all the documentation, examples IIRC came in the
developer pack.

Oh and just looking the .NET stuff in the additional docs and papers
section.

Maybe the ethereal developer list, should be someone there that could
give some pointer where else to look.

What ever you do, source code , data out / data in , error messages
always help.

Just saying it's not working or doing anything is useless.

thanks for the replies.

I did see the documentation and the sample code provided in the
winpcap.org.

yes it is the same .net project. I couldn't find much
help/documentation for the .net dll.

iam trying to analyze an IDS. so i am planning to use ethereal to
capture packets. I thought of using dotnetwinpcap.dll to send packet. I
am also trying to create a log for the packets which sucessfully passes
through the IDS, so that I can evaluvate the IDS.
I am a new B to winpcap,packets,IDS. I couldn't figure out why the dll
is not recognizing packets.
any ideas about this is much appreciated.

Stick to that , rather than dotnetwinpcap.

There are lots more exapmles / apps in C/C++ source code for generating
packets.

It's been a long time since I looked but there are quite a lot of
generators , www.google.com , mailing lists etc.

The only thing I have now is NAI Sniffer Pro and it's built in
generator, that's only because it's what's used at work.

In fact is has a very nice testing facility, record some traffic and
either replay it internally as a loopback or send back out on the wire.
This is great for test setups, as the same data set is repeatable.
