![]() This class contains Microsoft Windows Logon Protocol parser functions. This class contains Microsoft Windows Browser Protocol parser functions. This class contains Loopback Protocol parser functions This class contains Logical Link Control Protocol parser functions This class contains Internet Packet Exchange Protocol parser functions This class contains Internet Protocol parser functions This class contains Internet Control Message Protocol parser functions This class contains Hyper Text Transfer Protocol parser functions This class contains Ethernet Protocol parser functions This class contains Extended Interior Gateway Routing Protocol parser functions This class contains Domain Name Service Protocol parser functions This class contains Data Link Switching Protocol parser functions This class contains DCE/RPC Protocol parser functions. This class contains Cisco Discovery Protocol parser functions This class contains Address Resolution Protocol parser functions This class contains Apple Talk Address Resolution Protocol parser functions I also added some functions both to add support for different OS and to extend the use of ported functions. This class contains all ported functions of PacketNt.dll of WinPCap library. It contains functions for starting and stopping a capture session, loading and saving functions of captured packets, reading and writing function of capture parameters, etc. This class contains device specific constants. It contains variable reading functions, bit decode function, node display function, Win32 API functions, format functions, etc. This class contains all utility functions. This class contains device specific constants and structures. This class contains protocol related constants and function. CaseSenitivity enables to sort string data in case order and Enabled helps enabling or disabling the sort method to run. ColumnType defines what format the desired column is. Direction enables to sort data from lower to higher or higher to lower. The class has the following members:ĬurrentColumn defines which column will be used to sort the ListView. This class enables to sort list view items. It is the main project file which enables to communicate with other classes and to display captured packets. ![]() I am alone, and to port all protocols to C# is absolutely time consuming and tiring. At this point, I will be very happy if some of you are interested in this kind of projects, to finish it. My aim is to add all protocols supported by Etheral to my program and to make it available to all of you. Now my program supports over 15 protocols. ![]() And then (after getting the source code of it ), I used the source code to learn the protocol structures. It is really a great program and free.įirst I traced the packets captured by Etheral and built some protocols and was able to display them in my test program. My next search was to find a program with free source code that can display packets. Yes, now I could catch packets from the network card but I wasn't able to display them. And all these happen, a new class was created, Function. And then I wrote a new class to make capture process easy. After many weeks and debug trials, I finished it. So I decided to port the base library of WinPCap named PacketNt.dll to C#. My search attempts gave a result and I found a free library named WinPCap.Īfter previewing the WinPCap source code, my first trial was to write a wrapper class for it. And then decided to learn how it is done. And I noticed that many of them were using packet sniffer libraries. So I made a search on net about programs that can receive messages created by NetSend. I knew a program which I had downloaded and tested years ago. To say the truth, I didn't know how I could do that. ![]() Marc asked me "What about receiving message". 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.
