An update to my award winning Sniffer.Net which use my Sniffer.Net Library. I have included support for viewwing the contents of the packet by double clicking any packet from the list view. PackMon was my very first attempt of making a Network Packet Capturing tool in .NET i have created similar tools in vb6 using winpcap library. but this time i have created my own library in .NET which can monitor all network traffic. PackMon.NET is a .NET library is inspired by a similar code from http://www.mentalis.org/ their code was a great help for me i have converted some parts exactly the same from C#.Net to VB.Net but most of the code is entirely written by me. please give me Globes if you really like this code. you can use the library and provided sample application that use the library but please do give me credit for the same. This is still a beta version and i thought that together we can make it a really big and powerful project.
This time also i need support from you guys to help make this a really big success. i want to make it plugin based so that as one of user suggested we might use it as Firewall or bandwidth monitoring tool... there is so much that can be done with this but the next big update would be general purpose plugins plus editing the contents of the packet before sending to the target machine.

Nice... Very cool. thanks a lot. Would you also tell me how to display the packets in "readable" manner - in plain english like to see the contents of the package in english that in numbers?

This works great on a wired connection but fails on every wireless connection I try. Do you have any feedback on how to correct this. I thought you might want to include this functionality in future releases. (If this comment was disrespectful, please report it.)
Thanks you VERY much! That awsome! But there is a little problem... What about wireless connection? What I know, that the program "Ethereal" (for packet monitoring) dosn't working too until you tell the program not to capture in promiscuous mode (from the options), maybe it's could help...

Thanks for the suggestion and as we are very much busy in our live projects we could not get enough time to update this Open Source Project and need a community to help and enhance it to become more of a product rather being just a program. you can visit our website ie www.v2softwares.com to download the latest code and binaries for both versions of framework 1.1 and 2.0. we need the help of people who can actually part in the development of it and actively provide updates to it and we will make sure they would get enough recognision through our website and in credits section of the program.

The new version for Sniffer.NET is finally arrived. The major change in this version is the support of Plugins and the plugin architecture is very generic and every loaded plugin recieve the event on every packet arrive on the TCP stack either its incoming or outgoing packet and the plugin can reject or approve the request of this packet to be showned in the main application's list. the plugin manager is very powerful and a single assembly/DLL can contain more than one plugin. a sample plugin is also provided which act as a HTTP filter and once loaded only allow Tcp Traffic which arrive on port 80 or goes to port 80 of destination address. so you can use this plugin to show only HTTP Protocol's activities. i request you all to extend the funcionality by means of writing plugin for it.
Thanks

it is sad you do not mention neither credit where the original code comes from . This is not your own work mostly. Most code is from Mentalis.org and http://www.planetsourcecode.com/vb/scripts/ShowCode.asp?txtCodeId=2546&lngWId=10 (If this comment was disrespectful, please report it.)
below is half a function (can only a 1000 character message) to display the packet in a string format:
Public Shadows Function ToString(ByVal RawData As Boolean) As String Dim sb As StringBuilder = New StringBuilder(raw.Length)
If RawData Then Dim i As Integer = 0 While i < Raw.Length If Raw(i) > 31 Then 'sb.Append(CStr(Raw(i))) sb.Append(Encoding.ASCII.GetString(Raw, i, 1)) Else sb.Append(".") End If System.Math.Min(System.Threading.Interlocked.Increment(i), i - 2) End While Else (If this comment was disrespectful, please report it.)
below is the second of 3 messages with the function to display the packet in a readable format:
Else Dim rawString As String = Me.ToString(True) Dim i As Integer = 0 While i < Raw.Length Dim j As Integer = i While j < Raw.Length AndAlso j < i + 16 sb.Append(Raw(j).ToString("X2") + " ") System.Math.Min(System.Threading.Interlocked.Increment(j), j - 1) End While If rawString.Length < i + 16 Then sb.Append(" "c, ((16 - (rawString.Length Mod 16)) Mod 16) * 3) sb.Append(" " + rawString.Substring(i) + "" & Microsoft.VisualBasic.Chr(13) & "" & Microsoft.VisualBasic.Chr(10) & "") Else (If this comment was disrespectful, please report it.)
Last bit of the function(someone please clean up these posts for me and make public)......Just replace this function with the similar one in the packet class:
sb.Append(" " + rawString.Substring(i, 16) + "" & Microsoft.VisualBasic.Chr(13) & "" & Microsoft.VisualBasic.Chr(10) & "") End If i += 16 End While End If Return sb.ToString End Function (If this comment was disrespectful, please report it.)
Hi, I really like your work! I only using the PackMon.net.dll but my vb.net application only allows local admin users to use the dll. I have set up all the .net secruity settings but no luck! Any suggestions? (If this comment was disrespectful, please report it.)
There was a problem starting the packet monitor for interface 10.0.0.5 [The specified procedure could not be found] (If this comment was disrespectful, please report it.)
