packet sniffer

[W3SK]

Hello guys,

I downloaded the example from here: https://forums.ni.com/t5/Example-Code/Ethernet-Packet-Sniffer-Utility-Using-WinPcap-Functions/ta-p/3...

How do I add wireshark to look like?
Packets need to be put back read and stored in some format.
For example, when I send a picture, so the captured packets will be able to put together again.

Packets can connect as HTTPANALYZER, but data must be in shape  .halog or .xml

Please help me (my mail: petercinto@gmail.com).
I am willing to pay.
Thx.

Peter

Your question is not clear at all. The example you linked to uses WinPCap to capture the packets, and provide a simple frontend to see the data. Wireshark works the same way - it alsos uses WinPCap on Windows to capture packet data, and provides a pretty frontend to the packet data. So, what are you trying to do? Make the example look like Wireshark? I also don't understand what you mean by "Packets need to be put back read and stored in some format.". If you know the format of the data that you are receiving then what is the question?

Hello smercurio_fc

program packet sniffer using WinPcap library and it works great.
problem is displayed in multicolumn listbox packets in the order as they come.
I want my program as look wireshark.
I have loaded 100 packets and I can switch between them arbitrarily and decrypted data are shown below the multicolumn listbox.
Question: how do you remember the captured packets and writes them to the listbox with the option to switch between them?
               In which the SubVI is possible to realize this?

I am a beginner ...

thx. for advice

Peter,

It would seem that you are trying to log the packets, and look at a historical/chronological representation of them.  This example does not contain the ability to log packets, only view them in real time.  If you want to log packets like Wireshark, it would require you developing some add-ons, as it is not a functionality included in the subVIs.  

On a seperate note, it seems like Wireshark performs the function you are looking for, is there a reason to copy the functionality in LabVIEW?
