Project Name:   Packet Capture and Analyzer
 Programmer:   firat kocak
 Type:   Network
 Technology:  C#
 IDE:   NONE
 Description:   The first idea of writing a packet sniffer program came from a reply to my comments on one of the projects named "NetSend ( Sending popup messenger messages between computers )" by Marc Clifton. Marc asked me "What about receiving message". To say the truth, I didn't know how I could do that. I knew a program which I had downloaded and tested years ago. But I didn't know the way of it. So I made a search on net about programs that can receive messages created by NetSend. And I noticed that many of them were using packet sniffer libraries. And then decided to learn how it is done. My search attempts gave a result and I found a free library named WinPCap.

After previewing the WinPCap source code , my first trial was to write a wrapper class for it. But what I did was not what I expected. And I had no control over the code. So I decided to port the base library of WinPCap named PacketNt.dll to C#. After many weeks and debug trials, I finished it. And then I wrote a new class to make capture process easy. And all these happen, a new class was created, Function. Yes, now I could catch packets from the network card but I wasn't able to display them. Because I had no idea what they meant. My next search was to find a program with free source code that can display packets. Yes, yes, as you guess, I found it. Its name is Etheral. It is really a great program and free.

First I traced the packets captured by Etheral and built some protocols and was able to display them in my test program. And then (after getting the source code of it ), I used the source code to learn the protocol structures. Now my program supports over 15 protocols. My aim is to add all protocols supported by Etheral to my program and to make it available to all of you. At this point, I will be very happy if some of you are interested in this kind of projects, to finish it. I am alone, and to port all protocols to C# is absolutely time consuming and tiring.

witch IDE did u use .i can't make this program work
thx

we want any software to run this project?

Hi,

i am doing Packet Capture and Analyzer project..
i download the pacanal.zip from your post....
but it is not executing... could you help me to run the project...
